The quality and quantity of the light emitted from the Ceravision microwave powered lamp system is consistently better that its conventional counterparts. The molecular excitation of the bulb contents results in many more excited states being stimulated within the constituent materials resulting in a broad spectral light emission compared to the normal line spectra emission from conventional electroded bulbs. This allows simple bulb chemistry such as using Indium Bromide to accurately simulate the spectral output of noonday sun (6500K colour temperature). It also allows simple modifications to the bulb chemistry to be implemented at the point of manufacture in order to tune the spectral output to suit particular applications.

This is a highly efficient energy coupling technique, and in the Ceravision white light lamp system the conversion of incident power to emitted light is very high, with conversion efficiencies at the bulb in excess of 100 Lumens per Watt being routinely achieved at input power levels of 50-200 Watts RF.

In addition to the inherent efficiency of the energy coupling system, the microwave powered electrodeless lamp is built around a simple quartz bulb that contains no metal parts. In conventional bulbs, these metal parts will contaminate the chemistry of the bulb at its high operating temperatures, causing deterioration of the light output from Day 1. In the Ceravision system, the absence of metal parts in the bulb eliminates this cause of contamination and results in extended colour and luminance constancy.

It is possible to use materials in the bulb that produce high quality light at efficiencies that greatly exceed today's energy efficient lamps. These reactive materials cannot be used in conventional electroded bulbs.
