Luxim Plasma Light Bulb Kicks Some Serious LED Butt

[powercat]

Hi e2matrix,
thanks for the link what a shame they're not available to buy yet,  all my lighting in my home is LED maybe time to update,

there has to come a point in the future where the efficiency of lighting will be enough to be self-sustaining via a solar panel,
and the efficiency of solar panels is likely to get better as well.

As usual a lot of people making claims of very efficient circuits but as yet not even one genuine self-runner that anyone even with very good skills can replicate,
let's hope the new year will be different.

Having done any eBay search the only genuine ones I can find are
http://www.ebay.co.uk/itm/1w-Day-Cree-LED-12v-MR11-Downlight-Spot-Light-bulb-x4-/370536757573?pt=Lamps_US&hash=item5645b63945

I found these ones claiming 270 lm, Cree haven't even invented that one yet 
http://www.ebay.co.uk/itm/Cree-Q5-270-Lumens-1-W-Led-Headlamp-Flashlight-torch-E-/230719535192?pt=UK_SportsLeisure_Camping_LightsLanternsTorches&hash=item35b7f4b858

If anyone has a link to a genuine Cree that is over 100 lm for 1w and is available to buy online, 
can they posted  please.

While the new record represents a research-level breakthrough, likely based on the highest-performing chip from a wafer showing a range of chip performances, Cree has a strong track record of turning those laboratory results into full production â€" typically after around two years of further development.
The improved conversion efficiency of electrical energy into photons has an additional benefit, since the reduction in heat that is produced by the chip eases thermal management issues and luminaire design.

Among Cree’s best-performing commercial offerings currently â€" in terms of output efficiacy - are its cool-white (6500 K) XLamp XM-L LEDs, which are used in high-flux applications such as streetlights and industrial settings. They deliver a maximum efficacy of 160 lm/W at 350 mA, which falls to 150 lm/W at 700 mA due to the “droop” effect that impacts LEDs when they are driven at high currents.

That and Cree’s latest breakthrough will need to be replicated on a volume production basis to drive down the cost-per-lumen measure of solid-state lighting, in line with the rule of “Haitz’ law”, the LED industry’s equivalent to Moore’s law in the conventional semiconductor world.

Named after Roland Haitz when he worked at Agilent Technologies, the observation was first established in 1999, when Haitz and colleagues estimated the cost of LED light at about $100 per kilolumen â€" about 200 times as expensive as a conventional light bulb.

Using red LED performance as a guide, Haitz’ law predicted that the dollar-per-lumen cost of semiconductor light would decrease by a factor of ten each decade, while the flux per lamp would improve by a factor of 20 over the same period.
The improvement in performance of cool-white LEDs over the past decade has in fact beaten that prediction, and now exceeds that of conventional incandescent lamps. In a paper published late last year, co-authors Haitz and Jeff Tsao from Sandia National Laboratories said that to disrupt conventional lighting, SSL power lamps delivering up to 10,000 lumens with a conversion efficacy of 150-200 lm/W were needed.

The efficacy figures compare with a maximum theoretical limit of 400 lm/W that can be seen by the human eye. Cree’s existing XM-L emitters yield 1000 lumens at 100 lm/W.
