The Energizer Hard Case Professional LED Work Light is ideal for both indoor and outdoor use due to its durability and reliability. It provides the performance you need to get the job done, thanks to innovative LED lighting technology. Whether it's stepped on, dropped, or bumped, the lamp's robust construction of ABS plastic, steel, and rubber, along with its waterproof design, can withstand falls from up to 7 meters and operates even in the toughest conditions. The oversized button allows for easy operation, even when wearing gloves. Switch between different power modes to adjust brightness and runtime: In high power mode, the lamp emits an intense, bright light of up to 300 lumens with a runtime of 6.5 hours.
