The Grote Industries BriteZone Handheld LED Work Lamp, No. BZ421-5, features a digital readout that lets users know precisely what battery charge level is left. The magnetic polymer base secures the lamp to most metal surfaces. The work lamp emits up to 1,800 lm and offers three light patterns (100 percent, 50 percent, and SOS). The rechargeable light charges in 3-1/2 hours and has a run-time of three hours.
