Greenest LEDs

Most LEDs are built on Sapphire wafers. On average, more than 200 kWh of electricity are spent on making a 2 inch Sapphire wafer; a significant environmental burden.

Other manufacturers dice the LEDs without removing the Sapphire. Sapphire is a less effective conductor of heat acting as a bottleneck for heat transfer from the junction to the heat-sink. The Sapphire wafer is also lost.

SemiLEDs’ patented and unique process consumes no Sapphire, significantly reducing the Carbon footprint. The lack of Sapphire also removes a thermal management bottleneck while providing the most environmentally friendly LED on the market.
