The lightbulb of the future?

By Jim

Saw this news from watching a CNet TV live podcast.  Funny how the hosts showed a tictac and then motioned that a bulb as small as it can light the road.  It sounded like a jetsons story but I lingered to listen more.  The product has not yet seen production lines, but Luxim proposes that it’s main kick is that it is “greener” than traditional bulbs and incandescent lights.


Silicon Valley based company Luxim Corporation ( has released a “tic-tac” sized bulb that is good to keep streets well lit.  Yes… it’s as tiny as a “tic tac”!

Now while it’s almost as big as your Christmas tree lights don’t mistake the power behind this small gem.  It’s described as the product to offer a peek at the ultra-efficient lighting of the future.  Imagine 6 of these bulbs to light an entire city block. 

This tiny bulb contains an argon gas in the middle, as well as a component called a “puck”.  The bulb itself is partially embedded in a dielectric material.  And when electricity is delivered to the puck, the puck acts like an electrical lens.  Heats up the argon to a temperature of 6,000 degrees Kelvin to turn the gasinto a plasma that instantly gives off the bright light.

It’s almost as bright as the sun, the developers says.  The plasma bulb uses 250 watts, and achieves around 140 lumens per watt, making it very bright and highly efficient. By comparison, conventional light bulbs and high-end LEDs get around 15 and 70 lumens per watt, respectively.
