Inside a good quality Scangrip rechargeable LED worklight.
Since a co-worker had this rather nice rechargeable work light I asked if I could take it to bits and do a video on it. It's rated 20W and uses a 12V lithium pack to drive a 48 chip LED COB array. the case is very rugged and has a good optical system and heatsink. I've not tested the capacity of the battery pack.
