SL 2 and SL 6 are battery-powered task lights for construction sites. They are designed to overcome two limitations of typical jobsite lights: poor illumination quality and dangerous heat emission. Unique optics are surrounded not by mirrors, but by dark wells which absorb the stray light that causes internal shadows, leading to even, glare-free illumination across the work area. By using LEDs, heat output is reduced to safe levels. Where a traditional halogen bulb can reach over 117°C within 2 minutes, the SL 2 and SL 6 will not exceed 35°C. Heat sinks dissipate any heat to the rear of the tools, away from the user.
