Currently looking at Nitecore P20UV for a light with UV output so I can use it to check my currencies, etc.
Would it be a good choice? I understand it’s in 365nm wavelength.
My concern is that the price is a little on the high side, not exactly ‘budget’. I would appreciate any input from all of you for suggestions on other UV lights.
Thanks keltex78 for the suggestion! The wavelength is more than 365nm, and some fluorescent details might be lost? Would there be too much visible light?
To my understanding, that Nitecore has a very descent UV-led. There are cheaper end better options if you consider building one yourself (or get someone to build it) using the Ledengin LZ1 365nm led or the Nichia NCSU 276A 365nm led.
no, it is a different one, but it being chinese and budget, don't expect miracles from it. There are no reports yet on BLF of someone who has one, I just spotted three crappy youtube videos this afternoon (search for convoy s2 uv).
I thought this was recommended for use in a P60 light? Just needs to run 2 cells for best performance, might be better with 3, but I recall 2 being the way it was recommended.
I have the Convoy S2 from Banggood. After 30 minutes of use it is still working. However, comparing to the kaidomain one: http://www.kaidomain.com/product/details.S009842 , it appears to have longer wavelength. For instance, red square on Windows XP license sticker is clearly visible in KD light, while pretty pale in BG one. However, the fluorescence on white paper is much bigger with Convoy, so I guess it gives much more UV, just with longer wavelength. Wild guess is about 380 nm peak wave.
