Because internal areas of the body are not conditioned to bright light, care must be taken not to ‘dry out’or burn tissue. To avoid this effect, light sources use specific cool light wavelengths. LED technology hasmade its way into the surgical light source market and is now the main driver of growth. In the past, thelower color rendering abilities of LEDs was an obstacle to their adoption in the market. This is no longeran issue due to the increased quality of surgical cameras, which can compensate for the lower colorrendition abilities. Furthermore, the longer life span of LED bulbs, which can reach over 50,000 hours,reduces the total cost of ownership for purchasing facilities and makes LED light sources more attractivethan other competing alternatives including xenon, halogen and metal halide lights.Surgical light sources are often sold along with endoscopic surgical cameras and image capture devices asa part of a package. This means that these three markets are highly correlated and the competitors are verysimilar.
