Description
Full-size rechargeable aluminium duty light for professional users who need a 529 m beam and three selectable output levels.
The SL-20L is a full-size torch with a machined aircraft-grade aluminium body and a Type II anodised finish. On high it delivers 450 lumens and 70,000 candela for a 529 m beam, while the medium and low levels of 225 and 60 lumens suit close work.
Power comes from a 5-cell, 6.0 volt, 2.6 Ahr Ni-MH sub-C battery that is rechargeable up to 1,000 times and recharges fully within 9 hours, and the illuminated switch housing shows charge status while the light sits in its sleeve.
This item number is the 240 V AC and 12 V DC configuration and is supplied with two charge sleeves, so the same light can be kept ready at a base and in a vehicle.
