I just completed my first UV flashlight build in a convoy host.
I had ordered most of the parts last year, but with covid19 many of my parts never arrived such as my visible light filter.
Its a simple convoy S2+ host using their 1.5A driver I bought from their aliexpress store, im also using a 365nm LG3535 diode.
I think the output is more likely going to be around 4W since its a 3V LED running on a single 18650.
Other improvements I would like to see are a wider throw reflector, it seems fairly narrow beam with the standard reflector, and later I would like to upgrade to a more powerful diode and driver if anyone can recommend anything suitable for single cell operation. The LG3535 can run at 5W, im running about a watt below this i reckon.
Either way, its better than my crappy 380nm “3W” light that runs on 3AAA cells and drains them fast.
My uranium glass is glowing much better with this.
