WTB LG 365nm UV led

[andrx]

for my triple UV flashlight

this is the led

LG 365nm UV led tested (LEUVA33W70RL00, from Simon)

[image] This is the newest 365nm led that the Convoy aliexpress store has for sale, although it has been on the market for at least 2 years, just not affordable for private buyers until now. Simon only sells it already reflowed on a 16mm copper DTP board and that is how I tested it. Unfortunately they (I ordered 2) were extremely dirty, so I had to do extensive cleaning of the die (tissue and isopropanol) before I could start the test. Here’s the two boards that I bought, the left led I already…

thank you

I don’t have any to spare, but are you averse to the Seoul Viosys that Simon is currently selling? They’re pretty comparable. He expressed a little frustration that he was seeing higher failure rates with both of them after selling many of each. Just hard for them to handle the heat from overdriving, even just a little, in flashlight hosts that can’t dissipate very well. I don’t know what Hank is using for his UV emitters but he generally picks good ones/good bins, so you might try asking him (I’m sure he’d sell some to you).

Mouser, Arrow, Digikey…haven’t looked but one of them may have the LG…just watch the bin. If you google the model more suppliers might come up. Might treat aliexpress sellers as suspect unless you can confirm that they are selling the genuine product…lots of fakes and used emitters being sold because of the covid uv fad.
