Streamlight has introduced the key-chain Blue Nano Light to commemorate Concerns of Police Survivors (C.O.P.S.), a national organization that supports surviving family and co-workers of fallen officers. Streamlight will donate $1 to C.O.P.S. for each Blue Nano Light sold. The tiny keychain light measures only 1.47 inches in length, but its white LED delivers 10 lumens and features a 100,000-hour lifetime. Fabricated from machined aircraft aluminum, the light runs up to eight hours powered by four IEC-LR41 coin cell batteries. It features a rotating on/off head switch and a non-rotating snap hook for easy one-handed operation.
