Klein Tools’ rechargeable, auto-off head lamp has a light sensor that detects when the unit is in bright light and, after three minutes, automatically turns it off to save battery. It also has a bracketed strap to remove the light for recharging and a silicone strap to secure the headlamp on a hard hat for no-slip, no-stretch use.

Princeton Tec’s EOS 360 multiuse hardhat headlamp is attached to a slip-resistant, rubberized LED band that fits standard and wide-brim hardhats. The LED band has constant-on and safety flash modes and is covered in reflective strips.
