LED operatory lights?have been engineered to minimize?operator eye fatigue and to prevent?light from shining directly into thepatient’s eyes.?The brightest light is directed intothe oral cavity and becomes?gradually less bright across the?patient’s cheek area. The light head may be rotated?around 3 axes, for maximum?positioning flexibility.?Operators can effortlessly direct?illumination where it is needed?using one hand. Each operatory has different ambient light conditions. With this in mind, 300 LED lights include a stepless intensity control to adjust brightness to suit the actual operatory lighting conditions. LED output can be adjusted between 3,100 lx and 28,000 lx, while maintaining the 5,000K color temperature that is ideal for tooth shade matching. The Exact Brightness You Need.
