Both Induction Lamp and Light Emitting Plasma lighting technologies do not offer significant advantages over LED Lighting. They are simply a new spin on old technology.
Plasma and Induction lighting is similar to fluorescent, metal halide and high pressure sodium lamps because they use noble gases and rare earth elements to produce light. Light Emitting Plasma lights work by using radio frequency energy into an electrodeless quartz bulb which is driven by a solid state power amplifier. The process involves three basic steps to create light: a quartz bulb filled with metal halides, sits in a ceramic resonant cavity. The ceramic cavity called a puck is powered by an amplifier which in turn creates an electric field in the center of the bulb which ionizes the gases to create a purple glow. The ionized gases become hot which in turn evaporates the metal halide materials, creating bright plasma light.
In a nut shell, you have a typical metal halide quartz bulb, but instead of it being powered by ballast, it is powered by a solid state source. For sure these new plasma light sources far out perform typical metal halide lamps but are far from out preforming LED’s both environmentally and economically.
LED light sources are much better for the environment.
Many manufacturers of Plasma or Induction lighting heavily promote the green energy aspect of their lighting, but are they truly a green? The ionized gases used in Plasma Emitting Lighting are made up of noble gases. Noble gases make up a group of chemical elements with similar properties and under standard conditions they are odorless, colorless, monatomic gases. There are six basic noble gases and they are Helium, Neon, Argon, Krypton, Xenon and Radon. Krypton and Xenon are two of the rarest elements found on earth. One or combinations of these gases are used to produce light. Both Induction and Plasma still contain mercury a known environmental pollutant. Does that sound like an environmentally friendly solution?
LED lighting is the most efficient form of lighting today, LED’s use less wattage and last considerably longer than traditional lighting sources. Below is a comparison of a high bay Induction fixture from Luxim® and an LED luminaire from Lusio®. Both produce similar quality of light but there is a vast advantage in operating life and energy usage. Induction and Plasma lights take about 45 seconds to produce full light, LED lights provide light instantly.
|Luxim® Induction Light STA-25-03||Lusio® 4MS LED CW No Baffle||LED Advantage|
|Wattage||168w||119w||30% energy savings|
|Lifetime hours||50,000||200,000||4 Times greater life|
By implementing a Lusio® high bay solution you would save yourself 4 induction re-lamps and 49 watts per hour.
