Test x3: AAA UV flashlights: Alonefire SV62 365nm, SV327 395nm, Topcom 395nm fluorescent paint LED

All 3 have their reasons to exist. For spotting things up close the SV65 seems great. The SV327 should cure glues and resin very fast and the Topcom will be slower to cure but is cheap. #UVflashlight #Alonefire #Topcom

Thnk you.... great job! 👍 just a question if you want: regarding alonefire sv62 how long the autonomy? 10 minutes? 1 hour? thanks again

Respectfully, you should read up on the differences between 365nm UV and 395nm, understand the difference between UV and visible light, and understand the safety between UV-A, UV-B, and UV-C. The new SV62 you got there is FAR more powerful than the other two lights with it being 3W. You can’t see it, though, because it’s 365nm and, more importantly, has a visible light filter on it. That’s why the lens is much darker. Visible light just doesn’t matter and, in most cases, actually makes things worse because you can’t see contrast. You’ve upgraded big time from the those other two lights. Also, all of those lights are UV-A, which is perfectly safe for brief periods. It’s when you get into UV-B and UV-C where you really need to start taking precautions.
Also, a little tip for you. The SV62 is compatible with 10440 rechargeable batteries. If you throw one of those in there, you’re gonna see an even larger performance increase from it.

I leave the good knowledge to comments like yours. Thanks!

The lower it is the better it is for curing, 395nm is closer to visible light, 365 is closer to uv

The true 365 nm UV is blueish and is better quality because there is less near-UV (visible violet) light spectrum leak.
