Surgical Headlights
These factors will help surgeons see the light.
Y
our surgeons rely on headlights to illuminate the small-cavity
sites they operate in. Here are the features they say matter
most.
• Brightness.
A headlight should illuminate the site without the need
to reposition the overhead lamp. Its light should be even, not bright in
the center of the spot and dimming toward the edges. Light intensity is
measured in lux, with higher numbers indicating brighter light, and its
color temperature — how closely the light approximates natural day-
light — is expressed in degrees Kelvin, with higher numbers indicating
whiter light. The whiter the light, the more accurate reflection of the
illuminated subject's color.
• Mobility.
Headlights with xenon bulbs are connected via fiber-optic
cables to light source boxes, which are themselves plugged into electri-
SHINE A LIGHT A headlight should stay
in place to illuminate the user's line of sight.
