L2700 Series Operating Room Lamps are using advanced, high-performance LEDs as surgical light sources. It has lower cost of ownership because of low power consumption and long-life (service life of approximately 50,000 hours). A background illumination set of LEDs is included, which serves as the independent auxiliary light source for laparoscopic operations with streamlined ultra-thin design which creates little air resistance/turbulence and facilitates the delivery of purified air to the operating area. It has a digital control with 10-levels of brightness adjustment and automatic memory built together with high-performance German designed/manufactured suspension arm, detachable handle (easy to disinfect/sterilize) and alarm indicator displays when several groups of LEDs have failed.
