Advanced Temperature Regulation (ATR) adjusts the output of the HA11 based on the working and ambient temperatures. This feature ensures that the device maintains optimal performance while preventing the LED from overheating. The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.

The HA11 has a waterproof rating of IP66 and an impact resistance of up to 1 meter.

The HA11 includes: Headband, Clip and 1x Alkaline AA Battery.
