320-lumen ARC helmet light

The Nitecore HM01 mounts on an ARC rail and delivers 320 lumens of diffused flood beam through a TIR optic lens. It serves as a secondary fill light for ballistic helmet users who need stable near-field visibility while keeping a primary light free for tactical tasks. The articulating arm rotates 360 degrees so the beam can point in any direction. A single button toggles between two brightness levels for fast activation.

IP68 waterproofing and aluminium frame

The light carries an IP68 rating and a HA III finish on its aero-aluminium body for reliable operation in harsh climates. It runs on one CR123A or RCR123 cell and draws power only from that single battery. No thermal data, fan noise figures or external power requirements are provided in the specifications.

Runtime on high and low settings

On the high setting the HM01 operates for up to three hours and throws light to 80 yards with a peak intensity of 1390 cd. The low setting extends runtime to 15 hours for all-night coverage during sustained use. Buyers who need longer high-output duration or a rechargeable integrated battery will not find those features here.

Questions about this item

How do I attach the HM01 to my helmet's ARC rail and what step do people often miss?

Slide the light onto the ARC rail until it clicks securely; the step many miss is verifying the articulating arm pivots freely through the full 360° range before use.

What battery does the HM01 take and when will I need to replace it?

It runs on one CR123A or RCR123 cell; expect to swap batteries after roughly 1 hour on high or 15 hours on low output.

How long can I run the HM01 on high before the output drops?

The high setting delivers 320 lumens for up to 1 hour before the battery is depleted and brightness falls.
