A 3-in-1 video as BB2K Airsoft reviews three products from Olight: Olight I5UV, Olight S1R Baton2, and the Olight i1R2 EOS... "Today I'll show you the Olight# I5UVBlack light lamp. With 1000 lumens and a wavelength of 365 nanometers, it is ideal for authenticity checks, hygiene checks, geocaching, searching for minerals and much more. The OlightS1R Baton II is a very compact, 1000 lumen EDC flashlight that is in no way inferior to its bigger brothers in terms of function and performance. The Olight i1r2EOS is so small that it can be placed unnoticed on a bunch of keys and is always there when it matters. With 150 lumens and a range of 40 meters, cell phone torch looks pale in comparison."
