The SL 2 and SL 6 cordless work lights are characterised by their high illumination quality, which is generated without dangerous heat emission. The unique, mirrorless optics are surrounded by dark wells that absorb the stray light causing internal shadows. This ensures that the entire work area is illuminated evenly and without glare. By using LEDs, heat output and thus heat emission remain at a safe level not exceeding 35 degrees centigrade. Heat sinks dissipate any heat to the rear of the lamps, and thus away from the user.
