As tiny as peanut, powered by 4 alkaline button cells (IEC-LR41), as bright as 10 lumens. For this size, 10 lumens is pretty bright.Here’s size comparison of Streamlight’s Nano Light and my house key. So small and perfect for keychain, replacing my old Thrunite Ti that went to my mother’s pursue.
See how small it’s on my palm (I’m an average asian man). It came with a decent non-rotating snap hook for easy one handed operation when attached to a keychain.
Don’t get deceived by its size, this Nano Light will provide enough light to brighten your way to parking lot, locating your stuffs in a dark room, and a lot more than you can imagine.When I tried a ceiling bounce test, I saw the brightness of a 5 watt bulb being turned on.
I have no information on what emitter they use, it looks like a normal 5 mm LED to me. But I wonder how come a common 5mm LED can be this bright.
A Nichia, maybe?
