Continuously Variable Spot Size
Spot diameter adjusts continuously from 20 to 80mm at a distance of 420mm, so the lit area can be matched to the work rather than fixed by the design.
Continuous Brightness Control
Brightness is described as continuously adjustable alongside the spot size, giving the wearer two independent controls over what the light is doing.
5W LED Source
The illumination source is a 5W LED with a stated life of 20,000 hours of continuous burn, avoiding the heat the manufacturer associates with a halogen lamp.
Above 75000 Lx
Illumination at a 200mm working distance is listed at more than 75000 Lx, identical across both battery configurations offered.
5000 Kelvin Colour Temperature
Colour temperature is 5000 Kelvin, related by the manufacturer to bright, white, shadow free light allowing tissue characteristics to be seen without distortion.
Aiming and Fluctuation Distance
Direction of illumination adjusts vertically through plus or minus 25 degrees, with fluctuation distance listed at 12.5mm. Weight excluding the headband is 69g.
Two Rechargeable Battery Options
The portable pack is 7.4V at 4400mAh with run time from 7 hours; the wireless pack is 7.4V at 1800mAh with run time from 3 hours. Both are lithium and rechargeable.
Charging in Use and Battery Indicator
The headlight can be used while it is charging, and a battery power indicator is fitted so remaining charge is visible before a session begins rather than discovered partway through it.
