The Nitecore HA19 is a lightweight, all-purpose headlamp built to adapt to whatever the task calls for. From hiking and camping, Vehicle Repair, Night Observation to emergency response.

Its standout feature is Multiple Color Temperature (MCT) technology, which lets you switch between three white light temperatures depending on the conditions:

• Warm White (3000K) — easier on the eyes, and cuts through fog, rain, and mist more effectively than cooler light.
• Neutral White (4500K) — a balanced, natural-looking light suited to everyday, general-purpose use.
• Cool White (6500K) — superior brightness, maximizing visibility for outdoor adventures.

On top of the white light, the HA19 has dedicated auxiliary Red, Green, and Blue LEDs, each suited to a specific purpose:

• Red - preserves your night vision, making it ideal for stargazing, reading maps in the dark, or moving around camp at night without ruining your eyes adjustment to darkness.
• Green - favoured for wildlife observation and useful for reading maps, since it offers good contrast without the harshness of white light.
• Blue - commonly used for night fishing, since it can help spot fishing line and lures, and is also handy for tracking blood trails while hunting.

With up to 600 lumens of output and 130m max beam throw, the HA19 delivers dependable illumination across all these modes.

It runs on two AA batteries and is also compatible with Nitecore's NH2400 USB-C rechargeable batteries, offering up to 90 hours max runtime on the ultra-low level and 10.5 hours at the commonly used 100 lumen level.

Weighing just 61g and comes with a multipurpose mounting clip for attaching it to hats, backpacks or gear plus a diffusing stuff sack that converts it into a camping lantern.
