By popular request, a teardown of a bug zapper lamp. It's got three very distinct sections of circuitry and is quite nicely designed.
Note that this is a 200-250V lamp.
This video is a test video with louder audio.

Thank you BigClive. I am learning so much from you. Btw, I saw the fastest lap of the aisle of Man TT. Mind boggling.
New record 2023.
Makes me more concerned for the men that challenge that time trial. The machines are becoming so powerful that the penalty for failure sadly stacks up against them.
The Hopi looks to be very handy. Never seen one before..
Awesome
Those things kill everything but mosquitoes.
Clive is a true Engineer in his DNA. Engineers MUST take things apart to understand how they work. Their curiosity will not yield. What a fun channel. We need to get him to 1M subscribers!

It is suitable for 200Vac~240Vac or 90Vac~130Vac input voltage, with constant current accuracy less than ยฑ 4%. When SM2213EA adjusts the brightness in the 3-stage adjustment application, the output current can be changed in turn according to the power switch on and off, so as to change the brightness of the LED lamp. The adjustment ratio can be adjusted by external REXT resistance. When SM2213EA is in a 3-stage colour temperature adjustment application, the two output ports can be changed in turn according to the power switch on and off.
If I remember correctly, biting bugs, like bed bugs, mosquitoes and such are attracted to heat, not light, which is why theyโre such a pain from dusk on, because our bodies heat contrasts with the cold surrounding surfaces more when the sun is down making us more visible to them. Thanks for your videos, theyโre wonderful.
Omg dude i Love the break down of the circuitry but holy Smokes ya killing me with the popping open of the bulb x) they Screw off. Except for the bottom cables ofc. Unless mine's' are different model, which i wouldn't know much but Still gaves me anxiety Seeing the popping off apart the Sections Lol
I've been Looking to fix my bilbs as they began to flicker one day and then the function to the Light gor Somewhat wonky. I think i needa resloder Some components. Not Sure which ones though.
Ps. Yes. You're correct that the bugs that bite definitely don't pay much mind to the Light. So it's probably counterintuitive to have this bulb Set Up for that reason imo. However, i have Seen a few female mosquito Stuck on the Zappers when i done Some maintenance every now and then. I just know Some aren't fooled, as one day i had to connect tje extension cord to my Lamp desk and chased the Skeeter around my Shed Swinging wildly tryin to make it fly through the bulb haha.
IR or even just a warm resistor would do a better job at attracting biting bugs. They find you by both scent and body heat
"Kill A Watt" meters are everywhere…. not sure how accurate they are but if you're near a harbor freight you can score one same day no shipping if you really need one
My lamp is on it's third year now๐ And it zaps the bugs so they fleste thru the air and cross the room ๐
