The cool beam will not burn or dry illuminated tissues and is more energy efficient than xenon and halogen lamps. The headlight assembly consists of a unitary headset structure with easy to change power source and rechargeable battery. Its cordless design allows for complete mobility and virtually maintenance free operation.
