Operating theatre light designed to provide a high-intensity beam with excellent shadow dilution and accurate colour rendering. Spring-balanced arm makes positioning extremely easy, providing a precise and stable light-beam. Minimal laminar-flow interference. Fully sealed light head has been aerodynamically designed to minimise turbulence of laminar-flow sterilisation and purification systems. Conveniently placed panel contains on/off controls, a power-on indicator, bulb failure alarms and variable output intensity controls. Removable, autoclaveable light head steering handle doubles as a twist-grip focusing control.
