- A mosquito killer lamp teardown. Runs for an hour or so on a lithium 18650 1200mAh cell. Charged from 5V USB. Contains a lithium cell charger chip and a high voltage generator.

I recently bought a similar one, without the white light and without the Li-Ion. It runs on a cheap 5v 1A charger and I measured about 0.4A during runtime, and it has killed a lot of fruit flies and mosquitos. It's running 24/7.
Why would you buy a lamp for Mosquitos? I say let them fly around in the dark.
I don't want wasps in the shed.
Mosquitoes also can carry a number of diseases from other living things. That's the last thing anyone needs to deal with these days. I would have bug zappers all over my backyard if I could afford it, most all flies and mosquitoes go right for me when I'm outside and ignore almost everyone else 😢😢
I got your joke 😂
Bruh... Why did you get a weird magical and majestic light thing to kill my brothers
Wasps return to their nest at night :)
But does it work?
That 22MOhm resistor is not rated for such high voltage in such a small package! They should have used properly rated resistors or added 5-6 pieces of 10M resistors in series.
In my mosquito zapper bat, there's also a Cockroft Walton voltage multiplier that increases the voltage to 3kV. Originally, it had a 33nF / 2kV polyester film capacitor. I added a 68nF / 2kV cap and a 22nF / 2kV cap in parallel, and now mosquito zapping is a blast! The increased current (due to the low capacitor ESR and doubling the capacitance) doesn't just zap the mosquitoes; it instantly fries and blasts them!
BTW, the one you have doesn't just zap mosquitoes. It also zaps other insects, innocent crane-flies, probably lizards, and even midges, which are completely harmless...
Would have liked to know if it runs directly from the 5v1A supply for 24/7 use? Does it charge at the full 1 amp when the lipo is at minimum charge state? What voltage does it carry on the high side, and can it be "tuned" closer to the gap between the wires to make it more effective if an object fails to make mechanical contact between the leads?
So many questions, a missed opportunity for answers.
I tried one of these for some small flies that were annoying. No idea if they were gnats or fruit flies maybe but they were too small to touch both wires so it did not work for me. I'm looking for a smaller mesh size for the future. I ended up leading the pets out of the house by leaving a light on in the hallway to draw them out of the room they were in and then the back porch to get them out of the house. One light on at a time
I wonder if would still run off USB if you take the battery out ?
Now we may never know.
@@cheeseschrist2303 Yeah. :😞
I'd expect it would. If not you could likely trick it with a 4-4.2V Zener diode (plus current limiting resistor) in place of the cell (seen that done on tablets repurposed for stationary work after the battery died)
Are these any good for attracting and killing those tiny brown carpet moths (about 5mm) ?
Yes they are. I have one in the house for that purpose.
@@petertryndoch8857 many thanks.
Probably runs a long time because it only draws a heavy battery load while shocking bugs.. 🎉
I have an AC version of these. Very dim! The UV LEDs (their power supplies?) failed within a year.
Same. First one failed quick enough that the store gave me a new one under warranty. Second one lasted till the end of the summer that year, but did not live a particularly long life the next year.
I am not sure why these traps use ultraviolet lamps for mosquitoes the prey or blood host does not emit any light at all and are active at night in many places where there no light source . Flies and other insects are attracted to ultraviolet many flowers reflect frequencies in that wave length. I know that there are mosquito traps that use CO2 and infrared to attract then zap them both of which would work in the dark as well as the light
It charges at 5 Watts. It probably doesn't draw nearly as much when in operation. You should get considerably more than one hour runtime. You should test it and maybe swap in a better battery anyway.
I can guarantee those LEDs are ultraviolet, I have a lamp a lot like this and it emits that same purple light when it's on, but if I hold a sheet of paper up to it, the paper glows a white-blue, and much brighter than the visible purple light.I guess the ultraviolet LEDs output ultraviolet AND purple at the same time so you know it's on.
Hi! And how many mosquitto did you get?
@@yaroc07 Not many.
Pity you didn't measure that actual current draw, I think you'll find it's much less than the 5w on the label .... Maybe 5w when it's exterminating, or when using then white LEDs.
Julian, wasps have vital ecological roles transferring pollen and feeding on pests; they are an important part of nature. Great videos tho...
Yeah, I read that they're pollenators.
Wasps are aragant and wil sting you for no reason, while bees won't unless you bother them. All Wasps should be removed. They are just a bloody nuisance.
I have one of these. It doesn't even put out the correct wavelength of light.
...Strangely, there is no 'thumbs-up' button to click on your video....?
Ah, noticing that as well! Thought my browser or adblocker issue... I see the thumbs-up button, but when I click it, the previously shown dark button is now gone, it shows nothing!
wow
Scrunch up brown paper ,place in corner of shed.wasps think it's another wasps nest and don't hang around unfortunately it doesn't use batteries or electronics,why invent things when a paper bag does the job.
Wow, does that really work? I have a huge roll of brown paper. I'll try it.
Hi! I would be surprised that this trap will catch mosquito. I bet it will only catch flies and buterflies; but maybe I'm wrong? :)
Do mosquitos not like ultraviolet?
@@JulianIlett They are way more interested by CO2 than UVs
@@JulianIlett Not really. The can see polarized light which helps the females find water to lay their eggs in, but they are far more attracted to our CO2, body heat and other smells. There have been a few studies on "bug zapper" lights and they've shown them largely ineffective. They mostly end up killing moths.
@@yaroc07
Exactly. That's why the pet bottle trap is much more effective when used correctly.
Half a litre of active "Moonshine soup" will produce more CO2 than us humans, so a couple of those surrounding the BBQ party are very effective. Been there, tried that, got no bites to show for it. 🙂
@@bfelten1 What are the ingredients of "Moonshine soup" please?
I got a refund from AliExpress, because it is a weak lamp, and they falsely claimed it would cover a ridiculously huge area, and it barely attracted any insects compared to my standard UV insect k-ller!
LINK is broken
No it isn't
A fair amount of work has gone into mosquito traps. Dont waist your time with this one
Maybe you should learn about insects before you put out a video.
Maybe
