Milwaukee 2163-21 – Frequently Asked Questions

1) Will the Milwaukee 2163-21 headlamp attach to a standard hard hat, or does it only work handheld?
The 2163-21 mounts to a hard hat using 4 hard hat clips plus a rubber grip that holds it against the shell. It also detaches from the mount, so you can pull it off and use it as a task light or take just the light to a charger.
2) How bright is the Milwaukee 2163-21 hard hat headlamp and how long does it run?
Five output modes. Hybrid runs 600 lumens for 5 hours. Flood High and Spot High each put out 400 lumens for 9 hours. Flood Low and Spot Low drop to 100 lumens for 20 hours. If you need a full shift without touching the battery, run one of the low modes; hybrid is the mode for short bursts of maximum light.
3) How is the Milwaukee 2163-21 headlamp charged, and can crews swap batteries mid-shift?
It runs on a REDLITHIUM USB battery that charges through USB-C with the included 2 ft heavy duty cord. Charge times are about 50 percent in under 30 minutes, 80 percent in under an hour, and full in 2 hours. The battery is swappable and removable, so a crew can keep a second one charged and change it out instead of waiting.
4) Can I take the 2163-21 into a dusty crawlspace or work with it in the rain?
It carries an IP54 rating, so it handles dust and water spray, and it is built to survive 6 foot drops. That covers jobsite rain, overhead drips, and drywall dust. IP54 is not submersion rated, so do not dunk it.
5) Is the Milwaukee 2163-21 a spot beam or a flood beam?
Both. The headlamp has separate spot and flood modes at high and low, plus a hybrid mode that runs them together at 600 lumens. Use flood for close work like panel terminations or trim, spot for throwing light down a corridor or up a riser.
6) Can I tell how much charge is left before heading into a dark space?
Yes. The power button on the 2163-21 doubles as a battery charge status indicator, so you can check the remaining charge before you climb into an attic or a mechanical room rather than finding out when the light dies.
7) What is the exact part number to order this Milwaukee hard hat headlamp kit?
Order Milwaukee Tool 2163-21. That is the kit number for the REDLITHIUM USB hard hat headlamp, and it comes with the hard hat mount clips and the 2 ft USB-C charging cord.
