5000w solar LED street light

- An interesting light, but also a prime example of how eBay sellers are very prone to out of control exaggeration to sell their wares.
The circuitry in this mass produced item has been "optimised" to the hilt, with the charging of the lithium cell controlled by the microcontroller, no voltage regulation and no resistor in series with the LEDs which results in quite a squirmy current when tested on a bench supply.
The LED current at various cell voltages was:-
4V = 2A
3.4V = 1A
3V = 600mA
2.5V = 11mA
The lithium cell capacity yielded a slightly lacklustre 1200mAh on the first cycle. I may run some more cycles on it.
There are a few hacks that can be done to this light. First one is to add a 1 ohm (2W) resistor (or higher) to cap the LED current to a sensible level. That will also give longer run time on a charge.
The easiest hack is to swap the lithium cell for a higher capacity one, but note that the solar panel is probably only rated about 100mA on a good day. So the larger cell will only have an advantage in PIR only mode and with just occasional triggering.
From a waterproofing perspective, the PCB would benefit from a coating of lacquer or grease to shield it from condensation, the battery contacts would also benefit from some grease and the on/off slide switch is best bypassed.
The shape and angle of the case means that it should be fairly resilient to rain.
The solar panel is laid into a recess in the plastic case and covered in resin. Extremes of temperature may cause delamination or cracking of the silicon strips. It will probably discolour and cloud quite quickly, but that can be improved by polishing it with a fine abrasive cream like T-cut or toothpaste.

This also keeps the channel independent of UA-cam's algorithm quirks, allowing it to be a bit more dangerous and naughty.

The 5000W is assuming 240V input. for the same current at a nominal 3.7V you get 77W. And of course that's the equivalent power if it was a tungsten filament lamp so the actual wattage is about 1/8 of that, ie 10W. That's Chinese maths explained.
Your maths does make sense. Unlike the Chinese.
Ah, _Communism._
Ah, the perils of commenting on Patreon stream videos, when they go public you haven't a clue what the replies are about 😂
Can NEVER believe anything that lying cheating lack of quality control POS communist china tells you. Had cheating china relays marked 25 amps but with a 20 amp resistive load burnt out in 6 weeks. At best contacts were cheap 10 amp and wire was only 16 guage .
Somehow I doubt it's as bright as 100 x 50W halogen GU10 or MR16 down lights.
Other than the nonsense description, this actually looks pretty good! I love how they have an actual battery holder to make swapping out batteries much easier.
2 weeks past and I just received this post a day or so ago..wth?
Clive, for energy and recycling purposes, ECM blower motors at either UK 50, and or 60 Hz, U.S. 120, 240 vac, these motors, after the drive module pukes, make an impressive wind and stream mill wheel driven generstor. Oem horsepower plays a part but would you look into snagging one used , failed motor at your local hvac contractor house and maybe figure the best outpout at the least driven rpm, and a rectification, regulation, charging circuit for a power bank for the average joe wanting to save dollars on the power company, and power led lighting, charge smaller cells, and tools, an inverter to run the older appliances at their listed voltages (until someone designs and markets appliances at half the now power requirements.
I have putzt with these and am amazed at the low rpms, power output, three phase to single conversion . At about 6 to 10 rpm can deliver 40 to 60 vac 3ph., 3 :1 bridge rectifier phase conversion and voltage regulator in dc mode drop to 32, 24, 15 vdc with management .
Water wheel and pulleys, a 48 inch or 122 cm wind blade..etc.
Unfortunately, my domestic partner pushed me to trash seven of these motors, ready to be assembled.

Yeah as a solar powered garden light it looks decent - depending on how many hours it lasts - not 5000 watt though 😂
You've pushed the S.O.S. button, so I've call the international emergency coalition. I've dispatched them to the Isle of Man. I told them to use the infrared imaging system on their Super Stallion to search for the 5 kilowatt streetlamp! I hope this helps.
Wow. That light uses more power than my electric clothes dryer
Lol even mine have same lamp module but have 2 battery in it
My first thought was "so... an electric fire starter?"
20000 of those and a really long extension cord and l could easily power my light sabre.
With households installing more and more efficient lighting, cities are being forced to install less and less efficient, higher-wattage streetlights to compensate, so as to keep generating capacity constant or something. (ROFLCOPTER)
Battery technology has really changed to the point that I could run my entire house power needs on a single lithium battery and solar charging system. 😁
When I saw the title that's what I thought. I was expecting to see 4 12.8v 100 amp hour LiFeP04 batteries! I think they mean 5000 milliwatts 🤣
I already do. I am off grid for say 90% of the summer months between the equinoxes with 4kw of panels and a 10kwh Lithium battery. To do that I got rid of my plasma TV and replaced it with an LED TV and all my lights are LED types. I run my washing machine and air fryer etc only when there is enough sun during the day so you do have to plan a bit but not much. I have a Smart For Two EV and during high summer I can often add say 10% charge to that per day which gives me 10 miles which is more than enough for me.
Heck one of the power banks Clive reviewed a few months ago could power a Tesla for about 3000 miles, if the advertised rating is true!
@@John_Ridley some advertisers quote lithium ion power banks in milliamp hours to make the figures look impressive. I bought a cheap portable power station where they claimed 27,000 milliamp hour. The battery pack was actually 9 amp hour at 11.1 volts (3 series cells). So they're basing that figure as if it was a single 3.7v cell. They must think people are dumb. I ended up returning it and buying a lithium iron phosphate battery one. The manufacturers of those tend to not talk such nonsense 😂
Lol solar power homes that charge a power box has been around for decades
Glad to see that the A2HSB Mosfet can handle 5,000 watts of power!! Also i wonder how much of a 'street' this would actually illuminate from the top of a high pole!
1351 amps at 3.7 volts. Ummmm .. 🤣
Considering that we usually use around 120W of power for streetlights I would say that a single pole would be enough for the entire road.
I was actually wondering if Clive would have measured current & voltage, just to have an excuse to take out his cink palculator, and do the math to work out the real power of this seemingly good light.
And also that solar panel must be awesome!
I have 12x325 Wp that cover the shed, this tiny panel would put them to shame 😂
Last year I bought a Bluetti AC300, 3000 watt battery power station. The battery was so heavy that I could not carry it. I should have bought this single 5000 watts capable 18650 cell instead.
@@Ale-bj7nd 120w for modern street lighting !!! I thought the reason for councils changing to LED'S was to save power!! I think the old sodium lamps were around 65watts !!
I have four lights in my yard which use a charge and control circuit similar to this one. They’re in metal enclosures and branded “Better Homes and Gardens.” Inside, there are two 18650 “Westinghouse 2000 maH” cells paralleled. The output is a Luxeon LED, supposedly 120 Lumens. The solar panel is about the same size as the panel shown in Clive’s video. The oldest lamp has been operating for more than three years on the original cells. That is over 1,000 charge cycles. There is a slight dusk detection difference in the MCU. On my lights, there is about 30 seconds of hysteresis programmed apparently to prevent the moving evening shadows or passing car lights at night from making the light cycle off/on.
I have dusk-detecting garden lights that I upgraded with higher-capacity batteries. They've been going strong for a good 3 years as well.
Ah, great! I can connect that 5 kW solar panel to my Jackery Powerstation, and basically run my whole house off the grid all summer!
Budget build
Aaaarrrggh 😂 you should have warned us to mind our eyes before turning on that powerful 5000 watt light 😂
5000w!, Must be so lovely and warm standing under it, being that is such a powerful heater. I guess the gullible don't know that 5000 watts electrical power consumption produces the same amount of heat no matter what the type of load.
Has that battery tester been featured in a video before? I must've missed it if so.
Yeah, that looks so much more convenient than a light bulb & a stopwatch.
It's the first time I've used it.
Wow! I'm so jealous, our laser cutter machine is only 2800 W! Imagine what you can cut if you concentrated that light! You'd be able to cut through the bullshit for sure 😃
It reminds me of the youtube ads were a high school kid has a new kind of heating tech they dont want you to know about 😂 or an ac unit that doesnt need a compressor 😮
Ac unit and no compressor.. exists, sort of...
Search adsorption refrigeration.. ammonia and water, hydrogen. The cycle starts with a small gas generated flame, and when temperature is achieved , flame is reduced to a minimum to just maintain that temperature. The old mechanical systems were best with fixed high and low flame points but have evolved with electronics to extinguish and relight the flame..which requires more parts and battery backup.
Great refrigerator/freezer in the wilderness where local power utility is not readily available.
I’m slightly surprised the SOS mode does nothing. If this device were used as a front porch light, you could activate it to let others know you’re having an emergency. It’s one of the few places the damned ubiquitous SOS mode in LED devices actually makes sense.
The five thousand watt “rating” probably refers to how many watts it can expend before it dies of some random fault.
I’m honestly surprised yours had the battery on a holder rather than the more common soldered leads. I bought one of those from a 100yen store a few weeks back to set at my apartment’s veranda. Mine looked the same except that the battery inside had some very thin copper wires soldered to it and fixed to the plastic by a square of double sided foam tapes.
I was surprised by the battery holder myself.
I now have 4 of these ... 3 have a holder and 1 soldered on. All are the hang li cells ~ 800 mAh measured. They are mfr in various incarnations and arrays
Holder actually saves some time while assembling parts together.
I love how excited Clive gets as he breaks into things. It’s infectious!
5Kw with that solar panel size??? That's amazing! Like 5000% efficiency! Seems like we've been fooled for a long time by all the solar panel manufacturing companies 🤣😅(just joking of course) Now for real, it should illuminate an entire city with a true 5kw led floodlight.
From the thumbnail view I thought it would be a fairly large fixture, not 5000W of course but maybe 5000 lumen, if I had been drinking when I saw its actual size I think I would be looking for another monitor by now 😂
Oh come on, their finger just slipped. They meant it's 5000K not 5000W :D
Is this like those computer speakers you'd see with wild claims on the box like 1000w PMPO etc 🤣
Maybe SOS only works at full brightness or when its turned off? Mod a bigger battery pack to it and good to go, but the fact it has an actual holder is pretty nice by itself.
Doubtless 5000mW
Only 5000W? Is this smallClive channel? I would rather see 50000000W on BigClive
The Freznel Lens in front of the infra red sensors is used to create areas of higher/ lower sensitivity to maximise the change in level as movement occurs across the detection area. This is how intruder PIRs operate.

Cheers, I stand corrected :)@@TheDutchShepherd
@@robames1293 thank you for educating is on how they work :)
I have to say that it is not often I can add something to Big Clive's explanations@@TheDutchShepherd
Oh my, yesterday I just opened up the same type solar street light to do some test and upgrade, but mine is smaller (6 cob 48 point led), battery 400mAh, solar panel 6.2v 70mA. Great for ambiance garden light with remote control, but the only issue is the flickering on mode 3, still flickering even after adding additional resistor to the led.
Random flickering can be cause by a failing LED. Continuous strobing flicker at a fixed frequency is often just visible pulse width modulation.
they just forgot one "m" -> it is 5000 mW! Or just the small "w" in 5000w means milliwats :D
The FET marked as A2SHB has an RDS(ON) of 75 milliOhms at 2.5V gate voltage and 50 mOhm at 4.5V. They're probably using the combined resistance and voltage drops of the FET, the J3Y transistor collector-emitter and the internal lithium cell series resistance as a form of regulation. Cost savings is the name of the game.
It produces the same amount of light as a 5000w heating element 😜
if these were advertised correctly i'd say they are solid products
5,000 watts...pretty much like the 9,000,000mAH 4 cell battery banks they keep trying to see me :)
I would be curious to find out if the solar cell can fully recharge the battery after, say, eight hours of continuous nighttime use. Many of the solar lamps I've seen fall short of that, resulting in the battery being so depleted after several days of use that the light turns off after only a few hours each night.
Did you measure the actual power of the LED array?
Answer is in the video description.
I have one of these but the version without a remote, it’s above my garage door which is in a dark corner and has been working merrily away for a couple of years now. It is set to come on bright when anyone enters the area but stays off when no one around, best solar powered one I have tried in that position as doesn’t get full sun where it is.
The solar panel size of the stamp is obviously enough to keep running the whole household. Fantastic. 😂
Definitely in the realm of fantasy!
1:00 Yeaaaaow! You should have given a warning when the 5000-watt streetlamp was turned on. My eyes hurt! 😂🤣😂
5KW from one 16450. Wow! Future is made today!
5000W off a single 18650 cell is more than what the short circuit current of even high drain 18650s are, so not even possible when the 18650 inevitably explodes and sets your garden on fire.
Electric aviation should be easy now.
I bought a few of these. Very good so far.
That should give you enough light in the dark,..
SO YOU CAN FIND A REAL FLASHLIGHT 😂 👍
...18650, battery toys are starting to catch up
I've had about a dozen of these running for 1-2 years at a couple of sites and they've been perfectly reliable, even the ones in a place with 5m of rainfall a year. They make a good amount of light.
There was a slight translation issue when the engineer sent it to the packaging for English person. It is not 5000W (watts), it is however 5000K, (Kelvin). That means the light color is white, and has quite a bit of blue light in it. Incandescent is 2700K.
This is rated in a similar fashion to the mini 90,000,000mAh available on ebay. I'm going to buy half a dozen and power my whole street for a few months!
We live halfway up a mountain in West Wales, with forest around us. We have 4 infrared lights, mainly for the 8 dogs while outside at night. In 2 years 2 of these lights hve been replaced because of water ingress or condensation. The lights in this post look pretty good to replace any future failures. Good post, appreciate it Clive 👍
Tipycal LEDs have an efficiency of around 100lm per watt. The most efficent LEDs can reach 150lm per watt. Now if that torch was really 5000W, it would have been a 500000 - 750000 lumens 'torch'!!!! Imagine that...
I cant even Imagine how much Light that is but apart from that, to run 5000 watts of LEDs, a HUUUUGE battery and a HUUUUGE control Board (boost or buck regulator) are needed. Such a thing would be so big that it could't even fit in a car!
And then... Of course... The price...
Of course with 6.99 pounds you can get a 5000W LED Light. 5000 chinese watts though.
lol.. I have an actual 500W LED work light panel, it is about 30 times the size of this 5kW street light.
3 too many zero's on the write up (not yours) about the output! 5 watts maybe!

I'd consider getting a couple of those for the front door, only problem is it's north-east facing so doesn't get a lot of sun, particularly in winter when they'd be most useful. I really need a mains solution, but I find it very hard to get trades people to come and do small jobs. I had a devil of a job getting somebody to come out and fix some buggered hinges on my windows.

It sounds like what you need is that wireless power over Wi-Fi which Wiggl says they can do. It’s been a couple of years and still waiting to see their product. What?, it might be a scam? Oh no.
There are similar solar lights with the panel separate so it can be put up on the roof pointing at the sun.
5000 watts! Thats more than every led light in my house combined...12 times over. You would need 3 small Honda generators to run that single light.
I just wish people didnt fall for this crap.
3.7 volt cell into mah is what Chinese maths lol how not even 500 watt relatively, the real is= (12v*400ah = 4.8k watt) buddy 5000watt are used in stadium lights not street
Would’ve been interesting to know the max output from the solar & the current those COBs draw when at full brightness. This would’ve given a typical charge & run time.
There's more data in the description.
At 5000 watts, it presumably produces several gigalumens.
Once you said the capacity of the battery, the description started to make sense... It's a 5000mWh battery....
I just ordered one from eBay. $9.99 + sales tax and free shipping. Not a bad deal. I don't expect it to be 5000 watts... 😆
"SOS?!"
These have been $3.99 usd (now $3.59) on Ali all week. Quite a decent light at that price. Ordered several, the unit that arrived 1st, the 18650 came in @ 29 gr 800mAh. Quite puny but actually probably sufficient for my needs. It is in holder so 1 min to pop in more capacity if needed. No on/off switch. On one unit I'm thinking i will add usb charging and 3000 mAh cell . Plus a clamp and it will be a good work/camp lamp that can last a while and be topped off if needed.
I've configured one of these for indoor use by replacing battery with super capacitors for safety and leaving it permanently connected to a USB power supply with a tp4056 module. That was my favorite DIY project. It was a different version which I bought for $2
I got 3 of these the other day ( they light up my garden well ) and this video shows up in my recommended, nice.
5000w much wow. So compact 😅
The only time this thing will be able to dissipate 5000W is if the battery explodes, it goes on fire or gets struck by lightning.
This reminds me of the obnoxious trend in advertising for grow lights, where you'll see something listed as a 1000w LED when in reality it's more like 100 watts and they are saying it has the same output as a 1000 watt HPS or MH and they basically never even come close.
If that was an actual 5kW light the plastic housing without cooling would melt so fast.
The power draw is probably exaggerated a factor around 1000.

Just found a 90 billion lumen street light on Ebay. Wouldn't that just melt the cars as they go by?
I think one would be hard pressed to find ANYTHING that costs 7 GBP and does not burst into flames when 5kW passes though it. Maybe a short piece of copper tube?
I wonder the rating scaled down to Barbie and Ken. Probably still not 5K. Maybe 5K color.
These lights are absolute crap. I made the mistake of buying some. ☹️
Honestly this light doesnt look bad if you want streetlight style garden lights. Could modify this for external dc supply or external battery
Or modify with the ability to have a built in USB 5V charger so it can be used to charge a device.
It could be powered from a USB style power supply.
Just found the new and improved 9000W version on eBay here in Aus. 😂😂
I wonder how hot this thing gets in direct sunlight ... and how hot the lithium cell gets subsequently ...
our size should be 100000w😂😂😂😂😂
SOS - Signal to the Chinese police. Soon they will arrive at your door. ;)
The plastic case will melt when you turn it up to full power and fry your breakfast on it.
Only a few hundred subs away from 1 million.
It's genuinely impressive how cheap they've got this stuff down to.
It wouldn't hold up long in the UV, that plastic frame will crack in days
UV damage is my issue. In Colorado my hodgepodge assortment of solar lights get 8 to 10 hrs a day of sunlight about 320 days a year. Plastic gets brittle in a hurry around here. Clear lenses turn hazy yellow and other things just crack and break. On a positive note moisture ingress is low and humidity is lower so I don't deal with a ton of corrosion.
I've bought 6 of these things, but didn't consider U at the time. You are quite right of course, so I'll have to keep an eye on them.
Paint some aluminium foil black and cover it. No need to worry about the uv anymore
The PIR sensor and IR receiver supply voltage supplied by the MCU could possibly be turned off completely by the MCU when the supply voltage dips too low, in order to protect the Li-ion-cell from being depleted beyond its minimum voltage. That MCU could put itself into deep sleep when the supply voltage dips too low, until it gets woken up by the dusk&charge pin.
The probable for got the “m”, 5000 milli watt 🥴
I see it has the same emitter-follower circuit that needs nothing but a zener diode to control the charge just like that other circuit you showed in "Perplexing Solar Light".
10:29 Where can you buy this 5000w solar panel🤣🤣🤣
Sorry Clive but I've just had a quick search on eBay and found a 6000W LED solar street lamp. Just 1 hour and eBay can add an extra kilowatt. Isn't technology marvellous.
Damn! And what's the bet that as soon as I order the 6kW one they release the 7kW one.
Probably close to 5000mW, it nice enough though.
Thanks for the teardown, I enjoy seeing what they put into these things.
5000 watts is cap. Should you had measured the led's actual current consumption?
Data in description.
There are otp microcontrollers with semi-precision voltage regulators on die to reduce component count but they can only source a couple of mA. In this circuit it looks like J3Y is set to be an emitter follower like you'd see on the output stage of an old linear reg. If you tweak the bench supply up to 5v what happens? It would be great if things like the esp range would have internal regulation for single cell lipo operation.
Could the MCU be doing a crude PWM on that charge transistor? And switching from output to input, then measuring the voltage on the 100 Ohm resistor?
It definitely has to sample it intermittently.
Dude! Look at the remote! Its got the wifis also! 😂😂😂
Bought 3pcs about four months ago. Only one works now. Took them apart, the same part failed: the solar panel. The solar cells are in series, the solder joint between them is broken somewhere.
The resin coating on the solar panel doesn't handle UV well, full of tiny cracks on all of them.
That's why I prefer the panels with the silicon laid on a fibreglass substrate. The differing thermal coefficient of expansion of the plastic and resin layers flexes in hot sun.
5 kW of power, more like 5000 mW = 5 W. They forgot the little m in the print. That is about the max output of that rechargeable lithium cell.
5000W PMPO, eh? On a more serious note, I like the big-ass COB LED.
Peak lightning strike.
Chingaleas description in eBay posting
I used a similar LED sensor lamp to build a high-power flashlight. The COB module that has all the led's can handle absurd level of current as soon as you bolt it to a radiator. Main drawback is that the array usually has all led's wired in parallel, making it susceptible to thermal runaway. I was able to get away with 15W (5A) of power from a panel that is even smaller than the one in the video. Needed an additional DC/DC converter to step-down battery voltage and regulate led current but those are not that expensive on ebay either.
Great tear down as usual. I was wondering, did you measure the current through the leds?
That data at various emulated cell voltages is in the description.
@@bigclivedotcomThanks
Actually quite a nice circuit if that MCU is designed to deal with wide voltage range. Neat when a single I/O is used to do multiple things (properly).
Lot of 3.3V devices will still work down to 1.8 volts and the A/D converter internal reference is regulated internally at the lowest operating voltage (1.8V) or less.
Imagine thinking that you could by a 5,000 watt lamp for about $8....
Having seen a "real" water cooled 5kW Xenon discharge light (ex. light-house in the days that they still used this technology), unless physics nowadays is different, that doesn't look like 5kW, mind you the light output is reasonable for a standby exterior light.
This reminds me of an interesting device I found this week in a thrift shop. It is like a late 80s or 90s compact electronic device that accepts a regular light bulb in one end and it screws into the house's outside lamp. If you turn that light on and off two times in quick succession, the bulb will go into an SOS mode and it either flashes or blinks SOS Morse code.
I wonder how it keeps track! Maybe a capacitor that keeps the electronics powered a brief moment? I would totally mail it from the US if it was interesting enough to analyze
It usually is a capacitor after a diode or bridge, with a sense resistor detecting the incoming supply presence.
@@bigclivedotcom thank you :)
Hi Clive! I have a suspect USB-C/A 40w Deathdapter here that squeals like a stuck pig when drawing the full 40w from it. Actually anything over 20w can cause it. Would you like to do a tabletop Xray with your AvE xray machine? If so where should I send it to?
Why does it make that high pitched sequel when it is in mode 3 (dusk sensor)?
I didn't hear that. It will be the pulse width modulation of the LEDs.
Is it possible they mean 5000mW and the printer screwed up ?
No. They always have a war of exaggerated ratings on eBay.
Ngl, after watching this I kinda want a few for the garden.😊
They are worth it and very bright which is what everyone wants
Looks like a nice little thing. This would be great for garden illumination if you don't have a suitable mains powered light available (assuming the solar panel can get enough sunlight).
They're also only about £6 (and they haven't been price gouged yet).
All it will do is remind you every day that it would have been better to just run that cable.
@@andreasu.3546 In some settings (such as allotments etc) it may not be possible to even run a cable due to a lack of a mains supply.
In this case, these lamps would be decent (although perhaps not perfect).

There’s a left-handed and a right-handed haggis variety. One runs one way round mountains and the other the other way.
They very rarely cross-mate, but if they do, the offspring is the very rare Inverbollock haggis. These are born with wings and no legs.
The downside is that they can only breed amongst themselves, and the males always terminally damage their undercarriage when they land so they never get to breed.
