In PWM, the LED is driven in pulse of particular duty cycle. Due to this, LED is turned ON only for limited period (ON period) and rest of the time it is turned OFF . This method allows LED to cool down between two Switch ON periods. This helps in extending the life of LED.
PWM Technology maintains constant intensity and colour temperature throughout each surgical procedure
High wattage LEDs are used which increases the efficacy of LED OT Light.
Hence output of 1 LED of 10W is 30% more than 10 LEDs of 1W.
Also PWM technology helps in extending the LED life.
The vertical distance between the point of maximum intensity (Ec) of illumination at the centre of the illuminating field (one meter from the surface emission of light) & the detection of the value of 60% of central illumination in upward direction (LI) and downward direction (L2).
These values added together (1_14.L2), gives the depth of illumination without the need to refocus. The higher level of illumination depth is very important especially incase of narrow and deep wound channel.

Color temperature adjustment feature provides the ideal light for the planned surgery. User can choose color temperature settings from 3500K warm white values to 5000K cool white values. Color temperature adjustment is set in 6 steps between 3500 K to 5000 K values.
When surgeon's head obstruct the light path emitted from the OR light; the intensity of the obstructed petal is reduced and intensity of other petals is boosted, there by maintaining the light intensity at surgical site and also keeps very low temperature at surgeon's head.
The Combination of Latest-generation white & colour LEDs provides a high colour rendering index (CRI) and a very good reproduction of red colours (R9).
With colour rendering indexes Ra above 95 and R9 (red) above 98 the surgeon recognizes clearly the tiniest shade of colour in tissue.
