Plasma Light Bulb More Efficient Than Streetlight

plasma light bulb super efficient bulb

Plasma light bulbs are expected to the next generation of efficient lighting. It is said to be so efficient that it can produce light equivalent to the brightness of daylight.

Although the bulb is very tiny (slightly bigger than an LED), the plasma bulb burns extremely hot as its core can heat up to a very high 6000 degrees Kelvin…about the temperature of the surface of the sun (5500K). It can emit 140 lumens per watt, which is ten times more efficient as any incandescent bulb and double the efficiency of an LED.

The little pod sits inside a ring of “dielectric material” to concentrate an electrical field into the bulb. The contents of the bulb vaporize and the plasma glows. Just one of these tiny suckers are brighter than a streetlight.

The plasma light bulb is a Luxim product, which is now being promoted to entertainment industries for use in projectors and light displays.

  1. As someone who sells light bulbs for a living, I find this advancement to be exciting. Currently, we sell quite a few compact fluorescent bulbs, but many of our customers have concerns about their mercury content. If this technology were to become scaled down to a size that could be utilized by the average consumer, it would be far more efficient (in terms of lumens per watt) than compact fluorescents, and presumably less toxic.
