This is NOT a cheapo cash-register display light, it is an actual tactical law enforcement light (that is our main business), shrunken to keychain size-cops keep them on their keychains for backup purposes. It is all machined aluminum, rechargeable (adaptor included), and has light output of 130 lumens (for perspective, a typical keyring light might be 10-20 lumens). It is really an extraordinary little tool.
