| One in four lamp broken after one year |

 On E4 at Kalix underway Sweden's first test of plasma lamps in street lighting.
Drive modules is broken in three of twelve lights. But the Transport Administration continues Sweden's conduct tests with plasma lamps in street lighting.
Small as a mint, radiating like the sun. Plasma lamp, LEP - Light Emitting Plasma is minimal, but shines extremely strong.
Everyone sees LEDs as the future, but we would not bet everything on a single option. Therefore, we test also plasma lamps, said Stefan Ericsson, lighting manager at Transport Administration of Lulea.
A year ago, authorities Sweden's first experiments with plasma lamps in
street lighting. A total of twelve lights have been installed on E4 at
the entrance to the Kalix and at an intersection near Lulea airport.
Three have already died out after the drive modules is broken. Not
acceptable, says Stefan Ericsson. Mewn he would not scrap the project.
The technology is still exciting. It is incredible that such a small
light source can shine so strongly with a light similar to sunlight.
The lamps are from the U.S. lighting company Luxim. The light source
consists of a small glass capsule, filled with gas and metal halogens. You light the lamp by passing radio waves to the capsule, which
simultaneously exposed to an electric field. Energy of the gas to pass
to the plasma and to start sending out a strong, white light.
The lights in the test is rated at 273 watts, including ballasts, which
Transport Administration thinks too much. Now hope Stefan Ericsson to a
plasma lamp of 125 watts will soon be ready for testing.
To produce plasma lamps for low power has long been a concern.
Therefore, plasma lamps so far mainly been used to illuminate stadiums
and other large areas.
