I wrecked B&Q's biggest LED lamp then bodged a repair

- A teardown of B&Q's (like Home Depot) biggest lamp. It didn't go to plan.
Things worthy of note. If opening one of these, you have to remove the two screws from the LED panel - as they aren't just tapped into the aluminium heatsink plate, but into plastic pillars that hold everything in.
Given the poor thermal coupling and 15.5W rating for such a small LED PCB I wonder if they melt those pillars. The base has reasonable heatsinking capability, but the poor contact hints at a short lamp life.
I'm surprised that this lamp isn't in the same style of the common single PCB lamps with a linear current regulator on the same panel as the LEDs. Especially given its high power rating. I guess they may evolve in that direction in the future, as it is a much simpler way of creating the high power lamps.
The globe on these lamps is well glued on. You may have to take your time cutting through the silicone-style glue with a blunt knife (don't use a sharp one). Be careful not to lever too hard, as it may crack the plastic shell of the base.
There's a lot of room inside, so plenty of room for different power supplies (like the roughed up capacitive dropper I made) or even a custom low voltage LED panel for 12V use.

When faced with two screws that were screaming "Unscrew Us" why does Clive still go with a blunt instrument and destruction? Because that is what Clive is. And it's why so many love his approach to electronics...
Right? I learned early on, "take out all visible screws first" but Clive has taught me otherwise as I grew older.
Jack hammer needed.
Having spent a short period working on the returns desk at B & Q I’m amazed it actually worked at all.
Thanks, Clive! I think I've found my new life motto. "Not to worry. It's what I've done." It's just so simple, easy, and powerful. I love it.
I, too noted what you have said. I love this rationalization.
(Looking at the scar on my hand as Clive describes how I got it...)
That's a lesson you only need to learn once. If you're lucky, that "once" is someone else - stay safe everyone!
"Cut towards your chum, not toward your thumb." I've got a few of those myself.
Fast cut/super thin cutting disks on angle grinders are great for making nice scars on your hand too :)
I remember the triage nurse saying "Yes, it probably is" in reply to my question "Is that the bone at the bottom?"
It was quite a sharp knife!
The scar on my hand is from trying to catch a falling soldering iron. Don't do that.
I've slices the back of my right hand fingers open with sharp chain saw chain probably over 100 times. Filing the saw in the dawn hours of the morning, feeling less than alert. Chisel bit saw chain makes a nice deep gash...
I really thought we were going to see Clive slice his hand open early on. Ergh.
He's done that before.
So did Clive.
I know what you mean. Every time it would slip I was wincing.
.... with concern indeed.
That was one of those nononono moments
You popped it
I feel like we should gift Clive one of these gloves that professional fishermen use... that look like chainmail.
As a bonus it increases contact surface which is exciting when it touches some angry pixies.
What's the glove for? Would love one if it prevents your fingers getting hooked but seems like a fantasy 😂
@@TheMcspreader so do they help prevent piercing? Might aswell get a cheap chefs mitt if not
@@StalwartShinobi
Oyster shuckers use them.
@@ro63rto As do butchers. They are chainmail, very, very fine chainmail, and very expensive.
i had some anxiety effects watching you carve into that orb. "for those of us playing along at home".
If you get bored listening to BigClive narrating his frustration, you're life is too easy.
... is too easy.
(Don't come here to learn English.)
How did you arrive at that conclusion? :-)
I got one of those scars when I was about seven or eight years old, except that I was only trying to forcibly open an orange 🍊
reminds me of when the "hard bastard" of my year 5 primary school class managed to cut his hand open while attempting to open a yogurt pot with a plastic spoon instead of peeling the lid off, which he deemed himself too badass to consider.
I got one with a potato peeler when I was about 5 trying to spudger open an apple.
Got mine stripping a cable with a knife.
Got a decent life long scar from a knick in a tape measure running over my thumb. Bleed like a stuck pig and I still feel uncomfortable when a tape measure retracts quickly.
I now imagine you always opening oranges with a spudger.
"This is looking fairly promising."
I glance back at the title to make sure I read it correctly.
"I'll just show you on the.. shhhhhhhhhhhhhhcematic" LOL that was too much
Love the way he says that
schmoooo
Hints of JB!
BC is the Sean Connery of lights.
@@johnpossum556 omg ur right
Always cut away from yourself. To prevent cut wounds. Always Clive!
As a youngster I followed that rule when making various balsa wood model airplanes. One day the knife caught the grain and I whittled my finger. I still have a faint V shaped scar. Lucky the bone stopped the blade in time :-)
On a globe, all paths lead back to the beginning.
Many years ago i was making an airfix model kit of the HMS Victory, I was using a scalpel and was trimming some of the plastic from where it had slightly overmoulded and was pulling the blade towards me. In moment of stupidity i slipped and the scalpel blade went blade first directly into the end of my thumb right up to the hilt. It didn't hurt until i pulled the bastard out and that's when i found out that you have a pulse at the end of your thumb as blood spurted in rather large quantities all over the place. I look back often and laugh at this lol
The advice that I has was "always cut towards your mate"!
Ave says "Cut towards your chum, not your thumb""
Try putting the screws in the plastic with a small counter rotation you will here a pop when the threads line up then tighten the screen clockwise. It works well for old brittle Retro handheld computer's.
That wasn't bad really. Though as a rule I do tend to seek out and remove lots of screws. It's quite frustrating though when you are looking for a screw or a clip or something and I'm sat here shouting "ITS BEHIND THE THINGY". In my news, whilst watching this, I managed to embed the top of the SMPSU chip in the amp I am working on into my ceiling. This is because one of the aforementioned stray screws ended up stuck between the pins of another component, most likely the resistor and capacitor that I haven't found yet.
I have one on those exact butter knives in my toolbox, it makes for a most excellent spudger
same, it also heats up very quickly on a ZVS
I have a scar on my thumb from opening a starwars light saber with a serated steak knife as a child, I waved my hand about rapidly and after mum fixed me (nhs nurse) I realised I got blood on the bedding that had just been washed and splattered the white hallway wall paper and all 🤣🤣
Interesting experiment. New favorite quote - "Not to worry, its what I have done."
You need a few guitar picks or extra spudgers to hold the gap when you make a gap.
Stabbing yourself with a blunt knife is not fun either. I laugh so much when everything go wrong. Thanks Clive!
A stab AND a bruise.
Im intrigued by the effeciency to be had from using the inductor.
Even more effecient if it doesn't turn on at though, I guess. Thanks Clive!
The good thing about a sharp spudger is that the scars are thinner and heal fast. The bad thing about a sharp spudger is that the scars are deeper and more plentiful. Darn tradeoffs!
Someone needs to market a sharp spudger with a depth limiter.
B&Q = Block & Quale. I'm full of useless information LOL :D
At first I saw BBQ ... reminded me of the ultrafire lithium battery brand like in barbecuing LEDs
And here was me thinking it was Buy & Queue ...
That's almost as bad as our dollar-store soap brand: Klar & Danver. lol
The vast majority of the "more expensive 3 to 10W" bulbs I have opened here in Canada look exactly like that one. It's the cheap ones that are so easy to hack.
"What's the take-away from this?" Seriously Clive? I've been watching your channel for almost a decade now and I can't count how many times I've shouted at the screen "Take the screws out!" of "You missed that other screw!".
Thanks for the informative videos.
I like it when things don't go exactly to plan, that's usually when a video gets a bit more interesting.
A nuse once said to me that a cut with a sharp knife is best for suturing, a blunt knife leaves a jagged edger
However, a sharp knife is likely to go deeper.
Hey Clive, I figured I'd just let you know the reason behind their usage of the "Confidential" watermark is tied to the licensing of that document. If you look at the bottom, it has been labeled as "For Customer Use Only". Their point of doing this is to allow them to more easily go after people re-hosting the document or ripping parts from it without referring to their own site.
Hammer time , advice coming from a HCV mechanic . push on through all the way to the danger Zone !
I'd understand why the chip didn't like you. I wouldn't be happy if you came at me with a knife. 😂
"I am Rodger. I am a Spudger."
Also "I may have used unreasonable force." is my new favorite expression.
I can just see you in some adventure movie, charged to bring the big bad in alive.
We see you in your leader's office, you open a suit case and dump out still smoldering shins, ankles and feet of the big bad.
"I may have used unreasonable force."
It'd be easier to say "He George Floyded that light!"
Skip forward? Heck no! I sat down with a cup of coffee and a bowl of ice cream for this episode!
Have you ever put ice cream in your coffee?
that sounds like a painful, tooth achy, combination, my friend.
@@absolutely1337 Nothing like applying a bit of thermal shock to your chompers whilst relaxing to a Big Clive video.
@@absolutely1337 oh no. The ice cream is delicious and the coffee is to prevent brain freeze!
I have only just seen your videos for the first time. I'm onto my fourth one now. It makes a change from politics. Thank you.
"Not to worry, it's what I've done.". What an attitude to have, very impressive.
"If its glass, wear gloves" how about leave the lamp alone man 🤣 you save me from wrecking my house to see how things work, cheers mate
You made me look at the big ass knife scar on my hand. I wish I would have seen this sooner lol
I would like to recommend my favorite tool for opening and peeling anything: a small (3cm wide) putty knife that has been sharpened at the tip.
I have two, one sharpened just at the very tip, with a pretty rounded curve to the edge, and one that has been thinned out much further. The rounded one is far more useful.
Butchers security gloves might be reasonable LOL
@@TheMcspreader The choice between spending some cash vs a broken hand seems an easy one to me.
Anyone else get the feeling when watching a Big Clive opening up that it's almost the prelude section to a Casualty / Holby City accident? I sincerely hope not however; Big Clive is the best viewing going (take notice BBC!).
In the future, giant bulbs may be the latest fashion craze for robot headlamps. O:-]
This form factor is nice and easy when replacing about similar size traditional incandescent bulbs (mainly on porches etc.). Mine has worked about 10 years already. I think it's 18W or 15W rated and from Biltema. Not cheap though, was about 12-15€ back then.
I often put a bit of Vaseline on those self-tapping screws to avoid them seize or cross thread. I use the same mod you just made for this lamp. It will work for years.
"thermally connected by luck" Oh man this hits home.
It makes me feel better that even Clive bodges repairs...it seems its all I do
yes, Clive, It's like matches, Clive. you know - Strike AWAY from you - like you were cutting string or making a wooden twig whislte. Right Clive, back to watching.( Just had to put in this comment) ... Love your stuff - Education with alarm and satisfaction! Slàinte Mhath.
Adding the thermal compound "Release the schmoo!!"
Re: Spudger:
"Sometimes it works, sometimes it doesn't, sometimes it cuts my hand down to the bone. Oh dear, let me get my biohazard-proof pie tin" :-)
Pie Tins - not the Princes ones that you tin open open - dont use the tops as a frisbee - throwing or catching it will end in tears
Personally when it all goes awry that's when things get uniquely cool as long as nobody gets hurt.
I would throw some into slow color changer LEDs under that dome it looks like it would diffuse VERY nicely.
Good stuff regardless!
That big glowing orb..... I listened for the sound, but evidently no one was running.
As a child, I used to get up to all the things BC gets up to now. Nothing electrical or vaguely electronic was safe from being reverse engineered. I was once levering a very hard plastic case apart with a screwdriver (IIRC) and the case shattered. I still have the 1.25 inch scar on my thumb where the plastic acted as a makeshift scalpel. It compliments nicely the star shaped scar from a flying molten solder ball from tapping the soldering iron on the table to clean the tip.
I have a small V shaped scar where a BB entered my hand. It stayed there for 2 days until I got to a hospital and had it removed.
I've had great success opening lamps like this with a stout ceramic paring knife. Other things to try might be nylon spudgers or nylon bicycle tire levers. The thickness of the blade is often essential in liberating the globe from the adhesive holding it to the base.
That's a delicious pi filter in the power supply. Pity the rest of the lamp wasn't so well ingineered.
"Clive, what's in your hand?"
"A knife!"
"NO!"
Love your videos Clive! Your voice is equivalent to the David Attenborough of the electronics world
I did a bit of Googling - Dodge City was a Scottish DIY chain that B&Q purchased. So from the perspective of people in Scotland, it would have looked like Dodge City changed its name to B&Q.
I love your color coding to tell what is all connected.
Bloody hell Clive, Dodge City, That's going back over 40 years ago, I'm surprised anyone remembers the name.
ILL BET NOBODY SKIPPED FORWARD RITE ? !!!!!!!!!!!!
Clive, you really scare me at times, lol. Fantastic viewing and really educational. I cannot thank you enough for this Channel.
I see a chainlnk glove in your future Clive. I thought for sure it was going to be a skin repair video. Keep that superglue close at hand my friend.
My only lamp-related scar is from learning the hard way that a blacklight LED bulb's globe, while it felt plastic, was in fact glass.
I wish you would do a capacitive dropper tutorial! You glossed over it here, But it's very interesting. I still have that doppler motion detector, I showed you on patreon years ago. I meant to convert it to 120v, but wasn't sure I had the whole story on the math involved. What is the math you do to determine the capacity of the capacitor? Reducing that capacitance by half, and doubling it properly for your audience would be like a safety PSA :)
Really appreciate your edutainment Clive, If only we had a cross between Pound land and Ebay. They could call it Poundbay. Cheapo solar lights in one isle, IR motion sensors and Arduino clones in the next. Just the next town over.
I did a mod to a ledlamp, and reducing the power by modifying the current limit resistor, is limited in range. I wanted to go back to 40% of the rated power and the lamp started flashing. 60% was the limit.
I bought a bunch of 10 ohm pots which I put in series with the existing current limit resistors. Makes life much easier.
Cheers 👍🤝🇳🇱
It was already B&Q before the acquisition of Dodge City. Founded in 1969 as Block & Quayle by Richard Block and David Quayle, shortly afterwards they shortened the name to B&Q. B&Q bought Dodge City at the beginning of the 1980s
"I have a knife." is quite possibly the scariest thing I've ever heard BigClive say. 😂
Now that was a FUN video to watch! Cheers 🍻
“If you ever get bored, you can skip forward”
There’s just one problem with that...
I *never* get bored on a Big Clive video.
I took off a cover for a 16led phillip bulb. It was tough, as the glue was so thick it almost covered the led's. I have more respect for your efforts to create this content. Thanks!
After I had a Philips LED bulb die after many years, I also attempted to take it apart. That thing was utterly shredded by the time I got into it.
Thank you Clive
When you say 'pause for a moment' the only pause is on your side. :)
You don't say...
unless you also pause the video to go ... make a cup of tea/coffee, but yeah we should get at least time passed info when the recording restarts.
Those near misses with the spudger were even scarier than the bits of your battery tear-down video that had, "Right ok. There is actually... There's flames. Ok, right, yeah. Not sure of the science of this but this is all going on fire quite rapidly. So that's quite an exciting chemical. Oh, this isn't necessarily quite good. Where is my explosion containment pie dish because my bench is rapidly going on fire."
"not to worry, it's been done" is going to be my new life motto
I've got a lamp just like that sitting next to me waiting for me to go to B&Q to buy a replacement. It ran very nicely in my living room for something like 5 years. I'm going to wait for my second vaccination before joining the queues to get into the shop. I had a quick check and I think my one has a glass globe, or at any rate one that doesn't deform when I press it.
One amazing big led 💡
I had 2 of these last year in a previous house and they were brilliant!
According to the subtitles this has an 8.2 megafart smoothing capacitor. Sounds about right.
I used to think light bulbs were magic from fairy dust, then I subscribed to Clive and found out they have MOSFETs, capacitors, coils, inductors, resistors, diodes and use that elect-trickery stuff. As long as he doesn’t start an equine channel my unicorns are safe!
I think you have to be British and in your late 50s-60s to get the Catweazel reference.
Picked up one of these cheap a while ago. Bright enough to replace a fairly typical 3 bulb fitting on it's own and (for fear of tempting fate) is still going strong after a couple of years.
Ah butter knives. I was spudgering two pieces of plastic apart while telling my daughter to be careful doing such things. The knife slipped and went into my left hand in the webbing between thumb and first finger down behind the palm. Hurt like all heck and didn’t bleed. Gave me the shakes. We could look down inside my hand, pretty cool actually, you would have appreciated it on a “look what’s inside here, they’ve really buggered the assembly of this one, why do they have that going there for, what?” No stitches and back to work the next day. Everybody wanted to see it until they saw it.
I had a similar experience yesterday. I wanted to dim down a 15W ceiling lamp. It has a SIC9554A which is the same chip as the BP one but from Shenzhen SI Semiconductors. As the sense resistor it had 5.6R in parallel to 1R. I just removed the 1R which should have given me roughly 2.7W output. But the lamp did not light up, when plugged in. Instead it gave a brief bright flash every time I unplugged it. With the 1R back in place it worked as before again. My assumption is that the LED short protection kicked in. I will try it tomorrow with a lower value sense resistor. So there seems to be a lower limit to the power you can set.
EDIT: I just had another look at the datasheet and noticed that Radj for the OVP is also dependent on the Rsense. so, when I sixfold the Rsense I should have divided the Radj by 6 as well
It's nice to see there is something to be done about the horrible overwork demanded of the LEDs and with very little intervention with the circuit. All you have to do is avoid messing with this lamp entirely and grab a cheap one you can mess with without cutting yourself and breaking it to bits in the process.
don't feel bad. I just fixed the board on a $150 tablet only to destroy the thing when replacing the back. Good times!
Ok, Big Clive, now that you have a nice low power LED lamp, you need to fire up the 3D printer and make a moon globe for it!
I have a long scar on my right wrist from opening a violin. The painting knife I used had a nick in the end. Fun times.
We also have the Bayonet lights here in Africa. Fun fact, as per standard. Lights inside the house are bayonet (except for ceiling fans) Lights outside are screw-in
Thanks, Clive, that was fun perhaps not so much for you but a good result in the end, you could always put your ridiculously large filament that you made in the globe.
Hey Clive. I've enjoyed your LED light videos lately. I can't help but think you have discovered remnants from the planned obsolescence incorporated into light bulbs by the Phoebus cartel. It's very interesting to watch you, perhaps unknowingly (?), call out these hacks that can modify performance of these goods to the optimum efficiency and longest life they can handle.
This thought had only occured to me while I was watching another UA-camr discuss planned obsolescence and how it elvoved from the light bulb industry.
I'd like to know if you knew of this, as I think E waste is a big deal now for the earth and it's environments. Especially nower days when we have the technology to prolong the life cycle of electronic goods, such as LED lights, that we can erase a lot of the waste created by these products.
You have made me see the electronical industry, as broad as it is, so differently. It's amazing! You have a real thing going, bubbling under the surface of these videos that could spread and empower a good change for technology. It's just the greed of businesses and labour pirates that keep people buying over and over, even if it is just a bulb from the pound store.
Thank you for this perspective
I've gotten a lot of stab wounds and ripped skin from trying to open things with those shitty precision screwdrivers trying to unscrew things with the tiny metal grip thing just ripped open my skin happened a lot 😂
rope burns too
“Shmoo” made me chuckle 😄👍
I had a (temporary) scar to show from opening an LED bulb case with a blunt spudger. :-)
A suggestion Clive. Although you may already do it. When replacing screws into existing holes, particularly of the self tapping variety into plastic, it's worth turning anticlockwise first and you often feel the thread click as it lines up the start of the screw thread with that of the thread in the plastic. It means that you're not cutting a new thread but following the existing thread.
I normally do. These screws were a strange type that didn't lead in easily.
A heat gun works really well on those kind of objects if they are glued together. The glue melts the 2 pieces togetherl the heat softens the bond making it much easier to take it apart
There's normal globes, then there's these big chubby bubbles on a tiny little connection. "Squish globe"
amazing that they actually beefed up the application notice standard circuit to make it more RFI compliant.
Clive, bodging things never(!) great video mate, nice to know you are well keep safe 😁
I like it when things don't go to plan.
"This is looking promising" does not coincidence that well with the video title 🤔
B&Q bought Dodge City in the 1980's, it was a hardware store exclusive to Scotland, I remember because my friend worked at one that didn't have its name changed until 2016 and many thought that it was a rip off company of B&Q, despite the fact that they the same company!
Say Clive??...... a little while ago you featured a light bulb that looked like a fireworks display.... you think there might be a way of decorating the big bulb casing shown here to give it a similar look??? A universe in a light bulb would make my day :). Great video dude, now i know that if i can get a few of those bulbs ill be able to make an LED panel on an old radiator and mount these in an array :)
That led: lasts a short life
My incandescent light bulb in my food closet: *ROOKIE NUMBERS*
Edit: its about to celebrate its 29th year after installlation or birthday on may 13th
Gotta pump up those numbers! :)
Meanwhile my LED walk in closet lamp just died 6 months in.
Remember when LED lamps were sold as "lifetime" bulbs? yeah, they will last a lifetime- of a fly.
@@wyvern4588 i've yet to see one that lasts "a lifetime", which is what, btw? :))
@@Termiic it was when LED lamps were brand new to market, they all claimed 25 years to lifetime warranties.
Best I got on an OLD led lamp was 6 years, better than the 0-2 years today.
@@wyvern4588 I have halogen-like ones (GU10) that have managed to survive for 4 years now, but they are also one of early designs.
That little tiny bit of PCB acting as a thermal break for soldering purposes is interesting. I wonder if that came late in the design process when they realized they were difficult to assemble? It seems like a very fiddly thing to have to add to the manufacturing process.
I'd guess it's picked and placed along with the LEDs.
