Dont know if it would be suitable for a projector but interesting nevertheless

Silicon Valley's Luxim has developed a lightbulb the size of a Tic Tac that gives off as much light as a streetlight. CNET News.com's Michael Kanellos talks to the company about its technology and its plans to expand into various markets.

It looks like the microwave light ball that was posted a year or so back.

If its going to be used in street lights i cant see the price going to be too high. I dont think these bulbs produce that much heat either

Looks like there is more information in the press release on Luxim's website.

PDF warning: http://www.lifi.com/pdfs/PressReleaseLIFI-ENT-17Mar08.pdf

"The new module outputs up to 12,000 lumens from a small emitter in a forward intensity pattern with a color
rendering index (CRI) of 91 and a 20,000 hour lifetime."

Sounds very cool!

All I get for video is this though...

I'm sold, 20,000 hour life, 91 CRI, 140 lumen per watt, perhaps what a 3mm arc? It looks like the controller or ballast may be expensive but it is the perfect PJ lamp.

I would expect all the PJ makers to start using the lamp as soon as they can find a way to shorten the lamp life to 3000 hours!

Amazing.

Holy Frijole!! I wonder what the catch is? Imagine dropping one of those suckers into a highly reflective parabolic using thin wires to hold it in place and no "void" hole in back. Awesome.

I don’t think a reflector is going to be an easy option for this lamp. There needs to be a wave guide, a puck?, at the rear to direct the energy to the vessel. From what I can see in the PDF they have used conventional optics in front to direct the light.

I'm really liking this bulb! For only a 250w'r it kick the snot out of that 400w MH. No mention on heat generated, though. Bet if they came up with a 350w version it would destroy a 575.

0.55 min into video it mentions that a large proportion of energy gets turned into light instead of heat.

They have them in a Panasonic TV. Here is the Cnet review: http://reviews.cnet.com/projection-tvs/pan...l?tag=pdtl-list

If its in a TV, then it must be replaceable and purchasable from somewhere. Maybe a Panasonic service center will sell it.

ouch.

but what is the cost of a replacement bulb?

high initial investment, but might be worth it if the replacement is low as this uses a hella less electricity.

Aug 31 2008, 05:59 PM

Yeah roughly a thousand dollars for the initial investment. a bit high for my blood. maybe one day the price will drop substantialy

I know, this thread is kind of old, but all DIY forums in the worls are licking there fingers for the plasma bulb. Aint there a chance for a big group buy?
We could ask for a price for 30+ kits. Is there someone who allready has got a connection to Luxim?

I have contacted the people at Luxim, the lamp is real expensive. Around $440 with no power supply.

In what quantity? I guess about 50 peaces will be alot more cheaper that a single order.
is cooking something together with Luxim.

I found this somewhat interesting video from the competition's website. It looks like they've obtained a Luxim light engine and test fired it.
Still waiting to see the results in a projector - and still no pricing estimates.

for those interested, some screen shots have surfaced.
I only skimmed it, but it seems like some tweaking is still required.

Personally, I think sNOOp and the German community peaked my interest even more with their 250w UHP engines.

Oddly enough, I found an old thread from December 2005, where brainchild said the following:

QUOTE (brainchild @ Dec 19 2005, 03:44 PM)

...

For the elliptical, we have found a source for 250w UHP short arc lamps with an arc gap of 1.3mm. This will allow us to have a lamp assembly made using the ellusive elliptical reflector. Specs on the reflector will be given when we are done with the math. At this time we are establishing whether to use 'condensing' lenses to change the beam angle to match the variety of panel sizes, or to use several different reflector specifications. I will update you all when we know. The lamps are rated for 8000 hours. I believe the lamp assembly will cost about $100, with the arc being replaceable. With this arragement we expect to deliver a solid 10,000 lumens to the panel.

It doesn't look as if anything ever came of it, though.

Hi sNOOp,

I went on the competitor site and I read (in fact I try

) that Emil is using lenses in front of the bulb light One is a special 30 dioptrie but the others ???
Could you let us know in english

what is the lenses set up as well as the reflector diameter ?

giorgaki

Feb 27 2009, 08:28 PM

reflector diameter is 51mm

He's using 2 concave lenses, I can't remember the details but I think they're 63mm in diameter, not sure of focal lengths

By using 2 lenses, he can get a better spread of the beam angle since reflector is only 60 degrees (Decostar TITAN Halogen 60 degree reflector)

But I remember someone commenting on the vignetting, I'm not sure how even the spread of light is

This light engine is going to cost $680.00... WOW!!! I really want to see the LED light engine that Brain is working on getting from Luxcine.
