Energy Efficient Tungsten/Graphene Lamp Developed That Outlasts And Outshines LED.

(JUST IN CASE YOU DIDN'T SEE THE DATE OF THE POST ABOVE - 
THIS WAS OUR 2015 APRIL FOOLS DAY STORY - MAYBE SOME YEAR SOON IT WILL BE TRUE!)

Lambent Labs
The Defense Advanced Research Projects Agency (DARPA) and Lambent Labs is excited to publicly announce the development and commercialization of a new lamp technology that is more energy efficient and outlasts current LED and nanodot technology ten-fold.


Lambent Labs, which primarily works in developing and commercializing lighting intellectual property on special projects originally developed for DARPA has made a significant breakthrough in illumination technology.  By nanotizing tungsten and graphene and printing them in a honeycomb matrix on a nano level allows for 80% more surface area to illuminate and cool at the same time with less energy needed that all but eliminates the fragility and limitations of traditional tungsten/halogen lamps.


Now that preliminary patent work has been filed and approved, Chief researcher Franz Strahlend can now publicly discuss the initial results, and they are astonishing.  “The lowest  efficiency even with the sloppiest matrix layouts we’ve been able to achieve is 185 lumens to the watt using standard 120 volt mains power.  These lamps work just like traditional mains-powered illumination sources – there is no need for switching power supplies or transformers.”

The technology also allows developers to change the orientation and polarity at the atomic level to adjust the color temperature of the emitted light. The lamps will shift warm on the low end, but at full power Lambent had successfully created and tested lamps with color temperatures anywhere from 1900K to 7500K.


Strehland continues, “The life expectancy in the bake tests have been astounding.  LED manufacturers have been touting if you change out lamps when your child is born not changing until they go to college – on the conservative end we’re looking at life times more like needing a new lamp when your child retires.”


The new lamp technology will cost approximately 10% more than current tungsten/halogen lamps and should be available in any lamp form factor from A-lamps to ANSI lamps by Q4 2015.

The true breakthrough for lighting designers is that this new technology no longer leaves them asking mind-numbing questions about Color Rendering Indexes, Color Quality Scales, and R9 values.
