With a lens and reflector combination that provides excellent focus control, these headlamps produce brilliant illumination from the middle of the beam to the edge, whether narrowly focused as a spotlight or set as a broad floodlight. An integrated microcontroller regulates power to the Cree LEDs, ensuring consistent light output and long battery life. A mode button lets you easily switch the lamp on and off, or activate an emergency flash setting. When you hold the mode button down, the light dims steadily from full power to a faint glow and back to full power again, holding the desired setting when you release; the lamp saves this setting and returns to it the next time it is turned on.
Lightweight, water resistant and durably constructed, the lamps have an aluminum lens housing set in a rugged plastic body that can be tilted to six different positions within an 85° range. The housing is padded on the back for comfort, and the adjustable headband is easy to remove for washing. Designed, quality inspected and packaged in Denmark, the headlamps are assembled in China from components made in the USA and China. Each comes backed with a 5-year warranty against defects in material and workmanship, and is supplied in a rugged nylon belt/storage pouch.
The V3air model produces a beam that is adjustable from 5 to 150 lumens; an additional "boost" mode produces a high-intensity 250-lumen beam that can illuminate objects up 195m (640') away, operating for up to 3 minutes before returning to the normal "on" setting. It weighs 140g (5 oz) and runs on three AAA batteries (included) for up to 100 hours.
The V3pro lamp can output between 30 and 220 lumens; the boost mode produces a 320-lumen beam that can illuminate objects up 210m (690') away. It weighs 170g (6 oz) and runs on four AAA batteries (included) for up to 40 hours.
The V3pro Rechargeable model comes with a lithium-ion battery that provides up to 70 hours of power and can be recharged with the included charger or from a USB port (adapter cable included). The beam is adjustable from 25 to 170 lumens; the boost mode produces a 400-lumen beam that can illuminate objects up to 245m (800') away. Weighs 184g (6.5 oz).
