Sure, Haggai. Glad to help you and the CPF community!
I do see that Tank007 has changed their LED description on their store page, but you can still find the old "Japan Nichia LED" on some of their UV flashlight pages on aliexpress (AliBaba marketplace site). Luckily, I did capture the information from their site when I ordered it when all of their UV products were advertised to have Nichia LEDs. Not to mention the email reply where they confirmed the exact Nichia model.
I'm still curious as to what LED is present and its specs. I'd imagine that the wavelength is within 10nm of the advertised 365nm as the light is minimally visible and causes OK fluorescence. But not as good as a Nichia, by what I've heard and read.
