Elight RAIS is a technology primarily suited to the LED dimmable lamp retrofit market. It  is based on an extensive range of patents primarily covering the unique property of the topology that, at a particular frequency, the output characteristic becomes constant current on a single stage power supply with no sensing. This results in the topology remaing high efficiency through the full mains voltage cycle without feedback, unlike a conventional LC resonant circuit. This principle is then further modified to provide low voltage output drive, current magnification, near unity power factor, very high efficiency and compatibility with ALL domestic light dimmers. The simplicity results in very low production costs and very small foot prints.

This sets an ideal platform for Led bulbs to meet the Energy Saving Trust or Energy Star high performance ratings with the added market advantage of being 100% compatible with all types of domestic dimmers whether leading edge, trailing edge, push button or digital touch switch. The technology also combats the issue of minimum load.
