How is the BEACON different from a regular headlamp?

It adds a rear safety beacon with steady and blinking modes that makes you visible up to a quarter mile from all directions. The front headlamp still gives 600 lumens of spot and flood light.

Does the beacon hurt battery life?

Yes. Running the beacon alongside the headlamp draws more power, so expect shorter runtime than headlamp-only use. Carrying a spare REDLITHIUM USB battery offsets this.

Will it fit my hard hat?

Milwaukee says the elastic strap, silicone grip and universal clips adjust to any size or type of hard hat.

Can I swap batteries instead of recharging?

Yes. The REDLITHIUM USB battery recharges in the light over Micro USB or can be swapped for a charged spare.

It is rated water and dust resistant and tested to 2-meter drops, not for submersion.

What comes in the box?

The light, a REDLITHIUM USB battery, a Micro USB charging cable and the hard hat mounting hardware.

About the Milwaukee 2116-21 USB Rechargeable BEACON Hard Hat Light

The Milwaukee 2116-21 is a USB rechargeable hard hat light that combines a headlamp with a BEACON personal safety light. The headlamp puts out up to 600 lumens and has spot and flood beams. The BEACON light has steady and blinking modes and, when used with the front headlamp, makes the wearer visible from all directions at up to 1/4 mile.

It attaches to a hard hat with an elastic strap, a silicone grip and universal hard hat clips. It is made for hard hats from major manufacturers and is not designed for use without one. It is intended for roadside, tunnel and underground work, spotters, signalers and people working around moving equipment.

The REDLITHIUM USB battery can be charged in the light through the Micro USB port, or swapped for another REDLITHIUM USB battery. An LED fuel gauge shows the battery charge. The light is water and dust resistant and withstands drops of up to 2 m.
