Mosquito Lamp

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.

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...

Those 2kv caps don't last long due to constant shorts. Usually have to be changed every 6 to 9 months.

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

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 wonder if would still run off USB if you take the battery out ?

[mikepanchaud]

Are these any good for attracting and killing those tiny brown carpet moths (about 5mm) ?

[Moskito-brdc]

Bruh... Why did you get a weird magical and majestic light thing to kill my brothers

[DrKnow]

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?

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

[darkknight]

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.

[amirshakir]

Probably runs a long time because it only draws a heavy battery load while shocking bugs.. 🎉

[GWorxOz]

I have one of these. It doesn't even put out the correct wavelength of light.

[aaronbrandenburg]

When do you saying about The wasps.

And whether or not sensitive to that light.

This is really kind of the topic.However, this is something of interest that i'm found out and observed before finding out for sure.


Some mosts importantially bees.

Normally would not be attracted to the line. However, if the nest is disturbed night this can happen..

So
Most people would probably not even observe this most of the time.

Also, Something else if anyone has ever seen A cicada.

There was when real interesting.I did not realize but stirled the heck out of me with these guys one time.

Some species of cicadas actually have a distress call.

It's just about deafening, even bigger than the other calls of this caves.

One was on a wall and yes I got a good pick up the sky but haven't tried to take a closer pick and startled it and boy was iron for a surprise and a shocked system That is to the hearing.

It's interesting to think that some people will never realize until they've observed it first hand .

But yes, I can see an insect zapper zapping.Almost anything that would come its way and even if designed or implemented or handled or otherwise even opinion, none insect bodies spokennoise the person that's using it.

Ouch.

Haven't done this myself, but i've known someone that did once.

Then obviously only once after that experience.

They were replacing the black light tube and weren't thinking when they were checking at the maker's working and zap...

Surprise awakening that well.Couldn't fly about that better at the moment

[MarkDurbin]

Wasps return to their nest at night :)

[StephenBatchelor-lm]

Julian, wasps have vital ecological roles transferring pollen and feeding on pests; they are an important part of nature. Great videos tho...

[mrtechie]

I have an AC version of these. Very dim! The UV LEDs (their power supplies?) failed within a year.

[jonathanwood]

A fair amount of work has gone into mosquito traps. Dont waist your time with this one

[CoolDudeClem]

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.
