Lighter, Sturdier from UniBody Die-Cast Technology

Made from rugged aerospace grade aluminum alloy by the unibody die-cast technology, the major component of HA20 embraces a most sturdy construction with its integrated LED host and side axes. HA20 enjoys the durability and impact resistance that ordinary plastic headlamps cannot compare.

Full Metal Housing

With its extremely small thermal resistance, the full metal housing of HA20 can effectively transit the heat from the LED to its exterior. The seamless unibody design allows for larger heat dissipation surface of HA20, thus significantly improving its heat dissipation efficiency.

Advanced Temperature Regulation (ATR) Technology

Advanced temperature regulation (ATR) technology, along with effective cooling fins, allows HA20 to dynamically adjust output performance according to its internal temperature, thus preventing damage from overheating and prolonging its working life.

ATR Intelligent Temperature Control Keeping it Cool Inside Out

HA20 integrates an ATR module to adjust its brightness based on real-time temperature detection, avoiding excessive heat and ensuring HA20’s high performance from its compact body.


The innovative die-cast technology gives HA20 a unibody housing that eliminates extra battery compartment or magazine. Therefore, HA20 is lighter, handier than most plastic headlamps in the market.

Smaller Size

Upgraded industrial design to pioneer the use of unibody die-cast technology in making a headlamp housing that is impossible under conventional approaches. The better yet smaller components are delicately arranged into the compact housing; the two AA batteries are precisely fit behind the reflector. This design keeps HA20 perfectly balance in terms of weight, just to make it convenient and comfortable for your carrying and wearing.

Ergonomic Head Switch Design

Access all operations via just one hand

Direct Red Constant Illumination / Red Beacon

With the light turned off, press the switch partway down for over one second to enter red constant illumination mode;

In red constant illumination mode, press the switch partway down to switch between red constant illumination and red beacon. To exit, press the switch all the way down to turn HA20 off.

Portable Multimeter and Location Indicator

Upon battery installation, the red LEDs will blink to indicate battery voltage. With HA20 turned off, pressing the head switch activates the red LEDs to blink and indicate battery voltage.

Optimized Wide-Beam Optics

HA20 provides up to 100 degree of coverage to illuminate everything in a user’s field of vision.

Ninety Degree Rotatable

The product is ninety degree rotatable both upward and downward to eliminate illumination dead zones.

    Five Brightness Levels

  • 300 Lumen - Turbo
  • 160 Lumen - High
  • 90 Lumen - Mid
  • 30 Lumen - Low
  • 1 Lumen - UltraLow
  • Three Selectable Special Modes

  • Police Warning
  • S.O.S
  • Location beacon

Utilizes Two AA Batteries

HA20 utilizes two AA batteries that are universal, inexpensive and accessible worldwide. It is also compatible with rechargeable AA Ni-MH batteries.

Incorporates “Precision Digital Optics Technology”

PDOT utilizes digital simulation and precise point-to-point curved reflecting methods to optimize reflector performance. This translates to a more consistent, uniform and full-coverage beam capable of illuminating targets at distance.

Rotate Ninety Degree Upward to Hide Switch Part Inside Bracket

Suitable for long-period storage in backpack to avoid accidental activation.

IP67 Waterproof

Confronting rain and snow with ease
