Almost of the traditional surgical lights adopts PWM dimming technology, it adjusts the illuminance by turning the bulbs on/off at a high frequency, which will cause a certain damage to the surgeon’s eyes, on another hand, there will be waves during the surgical recording. L5 adopts the advanced DC dimming technology, which the illuminance is controlled by voltage changes without the high frequency flash of the light, prevent the surgeons from the damage and will no cause waves during surgical recording.

Different surgeries require specific illuminance, for example high-intensity lighting for heart and burn surgery, general lighting for superficial surgery, and low-intensity lighting for endoscopic surgery. L5 can provide bright, normal and endoscopic modes to satisfy several illumination requirements.
