Anyone tried the USB lights with bug zappers built in

Hey guys been seeing these USB/e27 lights pop up on eBay/wish/AliExpress now they're only 8w so nothing impressive. And they are blue/red grow leds (at 8w I'm not concerned about L per watt) But .. they come with a 1500v low amp bug zapper built in. I was concerned about that much volts in my tent. But running from a 5v USB it's Amps would be minimal. I'm guessing a capacitor builds power until needed. Then bam. Take that gnats/moths/flying thrips. Has anyone tested them?
Anyway I've ordered one and I do get minimal gnat issues so we should know if it's working. For $10 I'll give it a shot.

I was just thinking the same but with big regular bug zapper lights,/device's
