Aerodynamic design light head offer little turbulence, reduce the amount of bacteria circulated and provide more sterile working environment. Tool-free design allows for replacing bub within seconds. 99% of undesired thermal radiation is absorbed by specific coating filtration lens and reduce the heat generation in the light cone. Pass heat through the top of light head, away from the working field to ensure proper delivery of cool light.
