Description
A rechargeable aluminium-bodied duty torch delivering 450 lumens and a 529 m beam, for police, security and industrial users needing long-range light on shift.
The SL-20L is a rechargeable duty torch built around a machined aircraft-grade aluminium body with a Type II anodised finish. Its 5-cell, 6.0 volt, 2.6 Ahr Ni-MH sub-C battery can be recharged up to 1,000 times.
Three output levels cover both reach and endurance: 450 lumens at 70,000 candela for a 529 m beam on high, 225 lumens for 5 hrs on medium and 60 lumens for 20 hrs on low, with 3.25 hrs available at full output.
Key features
- 450-lumen high beam — High output gives 450 lumens at 70,000 candela for a 529 m beam and runs 3.25 hrs.
- Medium and low levels — Medium provides 225 lumens for 5 hrs and low 60 lumens for 20 hrs when endurance matters more than reach.
- Strobe mode — A strobe mode is available and runs 4.5 hours.
- Rechargeable Ni-MH pack — The 5-cell, 6.0 volt, 2.6 Ahr Ni-MH sub-C battery is rechargeable up to 1,000 times.
- Charge status indication — The illuminated switch housing indicates charge status, steady while charging and blinking when charging is complete.
- Anodised aluminium body — The machined aircraft-grade aluminium body carries a Type II anodised finish.
- Sealed polycarbonate lens — An O-ring sealed polycarbonate lens with a scratch-resistant coating protects the front of the torch.
- IPX4 and 1m impact — The light is IPX4 water-resistant and tested to 1m impact resistance.
Typical applications
- Police and security patrol work where a long-throw beam is needed after dark.
- Industrial and utility inspection in plant rooms, yards and enclosed spaces.
- Roadside and recovery duties for fire and emergency medical crews.
- Facility and perimeter checks on shift patterns where the light returns to a charger between rounds.
