3W LED Source
The illumination source is a 3W LED with a stated life of 20,000 hours of continuous burn, avoiding the heat the manufacturer associates with a traditional halogen lamp.
Illumination Above 35000 Lx
Illumination at a 200mm working distance is listed at more than 35000 Lx, identical across both of the battery configurations offered.
Daylight Colour Temperature
Colour temperature is 5500 Kelvin, related by the manufacturer to bright, white, shadow free light that allows tissue characteristics to be seen without distortion.
Homogeneous Field
The manufacturer describes homogeneous illumination across the whole field of view, so brightness does not fall away toward the edges of what the wearer can see.
Twenty One Gram Head Unit
Weight is listed at 21g for the head unit in both configurations, which is what makes wearing it through a long procedure realistic rather than merely possible.
Vertical Beam Adjustment
Direction of illumination is adjustable vertically through plus or minus 25 degrees, letting the wearer set the beam to their own working posture.
Two Rechargeable Battery Options
The portable pack is 7.4V at 2300mAh with a run time above 9 hours; the wireless pack is 7.4V at 1800mAh with a run time above 6 hours. Both are rechargeable lithium.
Charging in Use and Low Battery Warning
The headlight can be used while it is charging, and a low battery indicator light gives warning before the illumination is lost mid procedure.
