Description
Full-size rechargeable polymer duty flashlight with four output modes, delivering 450 lumens and a 529 m beam for professional duty and utility users.
The SL-20LP is the polymer version of Streamlight's full-size professional duty light: a lightweight, impact-resistant nylon case with a non-slip rubber comfort grip, an O-ring sealed unbreakable polycarbonate lens with scratch-resistant coating, and a 5-cell, 6.0 volt, 2.6 Ahr Ni-MH sub-C battery that is rechargeable up to 1,000 times.
High, Medium and Low levels plus a strobe cover everything from close work to long-range identification, with 450 lumens, 70,000 candela and a 529 m beam on High and 60 lumens for 20 hrs on Low. The light is IPX4 water-resistant and tested to 1 m impact resistance, and measures 33.5 cm (13.2 in) at 0.59 kg (1.3 lbs) with battery.
An illuminated switch housing indicates charge status, steady while charging and blinking when charging is complete, and the light fully recharges within 9 hours.
