Choice of power UV leds for a "multicolor" UV flashlight set

[CRX]

Djozz tested some UV emitters, you might find useful.

4 more 365nm UV-leds tested

Last december I updated my test method for 365nm leds and tested 4 leds (link). With the same method I tested and extra four 365nm leds and put all 8 in one chart. I think that this chart is getting way too busy, so for any more tests in the future I will only plot a selection of old tests for comparison. I measure the leds in my usual way, I test one bare led, if possible on a DTP-board, cooled very well, starting at low current and at each increasing current setting letting the led settle …

I use a Seoul Viosys 365nm with ZWB2 filter in my DQG Hobi pocket carry.

You almost always get some stray light from these emitters so appropriate filters are a good idea.
