The SureFire Helmet Light HL1-A-TN has a lot of capability in a small, low signature package.
Illumination sources include three multiple-output white LEDs, two multiple-output blue secondary LEDs, and a blinking infrared LED that acts as an Identify Friend or Foe (IFF) beacon.
The three multiple-output white primary LEDs provide light in front of the operator. With three output settings (high, medium and low), it is good for general close-work when the situation allows for white light. The output setting is controlled by a pressure switch on the side of the helmet light's body.
The three multiple-output blue secondary LEDs provide forward projected illumination in a lower-signature, more night-vision-friendly colour and is extremely useful in casualty care. The blue light allows for the identification of blood and fluids on exam gloves while still maintaining a reduced light signature.
Battery included: CR123A
