The 3M HL300IS is a versatile headlamp that allows hands free lighting for industrial workers that need Intrinsically Safe certification. 150 lumen intrinsically safe light with flood and spot lights for use with 3M hard hats. Weighing only 92 grams but able to run up to 108hrs in spot setting and 95hrs in flood setting, this waterproof (IPX-7 rated) hard hat mounted head lamp is popular for rugged industrial lighting applications or use in areas that require intrinsically safe equipment.
Comes with 3 AAA batteries and three attachment options. The rubber headband provides a secure attachment for the headlamp to most 3M hard hats. The 3M Dual Lock fastener works well for securing the headlamp to many hard hat designs and materials. Providing a strapless attachment option allows the headlamp to be secured without it interfering with earmuffs and other hard hat attachments. Securing the headlamp without at strap reduces interference with earmuffs and other hard hat attachments. The nylon headband allows the lamp to be worn by the user without wearing a hard hat.
