Are UVC LED Bulbs Bogus?

Because of the pandemic these UVC led bulbs are all over eBay. Are they really in the 200 to 300nm wavelength range or are they bs? Pretty expensive right now. I do have the cfl uvc lights that work great but would switch to led if legit.

Long lasting uvc/b leds are a recent thing, they are expensive and a prime target for scam… Be careful what and who you buy from. Also can take a while to kill stuff with them depending what it is. Uvc causes cancer rapidly.

I only like high CRI, I have or have had in order of pref:

Fireflies E07 219B SW45

Fireflies ROT66 219B SW45 D220 (in the mail)

Emisar D4 SST20 4000k frosted lens (the lack of some preset levels kinda makes me want to rate it lower though...)

Jaxman E2L 219c 5700k (indoor use only due to color temp)

Jaxman E2L 219c 4000k

Klarus Mi7

 

Varmint removal (throw):

Convoy M21A C8 ver SST20 4000k (5a)

Convoy S2+ SST20 4000k (3200ma)

considering single uvc led costs about 10-15 bucks minimum, (and those are top of uvc bandwidth, less effective part) yea, i’d say close to 100% of those uvc led bulbs sold, are scam.
digikey sells uvc leds in 270nm range less than a watt of power for around 120usd each.

yes ebay and amazon are littered with cheap uv-c claimed lamps.
real uv-c leds are not cheap so when you see a “corn bulb” loaded with hundreds for $15 you know its a scam.
purple is just purple.
not uv-c!
