Companies producing or developing plasma lamps include Ceravision, Luxim and Topanga Technologies.
Luxim’s LIFI, or light fidelity lamp, claims 120 lumens per RF watt (ie before taking into account electrical losses). The lamp has been used in Robe lighting’s ROBIN 300 Plasma Spot moving headlight. It was also used in a line of, now discontinued, Panasonic rear projection TV.

High-efficiency plasma lighting is the class of plasma lamps that have system efficiencies of 90 lumens per watt or more. Lamps in this class are potentially the most energy efficient light source for outdoor, commercial and industrial lighting. This is due not only to their high system efficiency but also to the small light source they present enabling very high luminaire efficiency. Continue reading “High-efficiency plasma (HEP)”
The use of a high dielectric waveguide allowed the sustaining of plasmas at much lower powers – down to 100W in some instances. It also allowed the use of conventional gas-discharge lamp fill materials which removed the need to spin the bulb. Continue reading “Heat and power of Plasma Lamp”
Around 2000 a system was developed that concentrated radio frequency waves into a solid dielectric waveguide made of ceramic which energized a light emitting plasma in a bulb positioned inside. Continue reading “Plasma Lamp Size”
In the past, the life of the plasma lamps was limited by the magnetron used to generate the microwaves. Solid state RF chips can be used and give long lives. However, using solid state chips to generate RF is currently an order of magnitude more expensive than using a magnetron and so only appropriate for high value lighting niches. Continue reading “Limited life of plasma lamp”
Modern plasma lamps are a family of light sources that generate light by exciting a plasma inside a closed transparent burner or bulb using radio frequency (RF) power. Typically, such lamps use a noble gas or a mixture of these gases and additional materials such as metal halides, sodium, mercury or sulfur. Continue reading “Plasma Lamp Description”
Plasma lamps are a relatively new (as of 2009[update]) type of highly efficient electrodeless lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s. Continue reading “What is Plasma lamp?”
