You can find a lot of infos by You Tube and Google and on LumenLab too I didn't see this tread http://www.lumenlab.com/forums/index.php?showtopic=24873

The problem is finding someone who sells them. Or are they actually available now?

I agree that these look like they'd be awesome. As long as they can be bought. When a 250W setup like that can be purchased for a couple hundred dollars (Which would still be too expensive for commercial use replacing 400W HID lamps) then I'll buy one.

i don't know is it ok to give you link for buying since it is concurrence to this site? (asking admins too:)

SupraGuy - yea, it's too much comparing to MH kits, but if you have in mind life span, 500$ for a long, long time... anyway, I would rather wait for some 350W or higher. by this tempo, it would appear for 1 year as much.

The LIFI-STA-40-02 series can be found online now. Google "40 series plasma"

Here is a link to the Luxim site.
18300 lumen, 30,000hr life, 5300k, 95 CRI, ~260w draw


Luxim isn't in full production yet though. The ones available now are a limited run that they are selling to possible venders in different test markets. Prices vary from $600-1000 per until, depending on where you find them. I have seen them going out to industrial lighting, aquarium, and DIY markets.

I have been watching the company really closely over the last year. This is the last stage before full scale production can begin. They have to figure out what markets will give them the big numbers, so they can set up the production runs to maximize profits. One market analysis and a bean counters report from success or failure.

OK so with a 40,000 lumen MH bulb, we get around 250 lumens on screen.

But with a bright enough LED array we will have much better efficiency right?

Because with a 40,000 lumen bulb we lose at least 50% or more lumens because we lose most of the light coming out of the top/bottom of the lamp. Whereas we capture a good bit of the light from the front/back with a good reflector.

Also with a good LED array we will remove the rear fresnel.

So anyone want to hazard a guess at what would be possible from an array of these?

EDIT: Nevermind I mis-read. You meant an LED array, I think. My bad.




Yeah, that is my thinking also. One 267w Luxim will be pretty close to a 400w MH in PJ lumen output. It would get less heat, draw less power, achieve better focus, and have better colors though.

The problem with an array would be the luxim's size. At 100mm diameter per emitter and with a 1/4" x 1/4" light "beam" the "pucks" might be spaced to far apart for an effective array. You would have to go all Frankenfressnel.

ROFL

Well, LEDs are LEDs. I'm thinking about this plasma lamp.

They're talking 170lumens/watt, at 250W that's 42,500 lumens, which is about 5% brighter than a 400W MH.

The really cool thing though is that the plasma light source is just 5mm in diameter, so this means that we don't have nearly the arc issues to deal with. This puts the lamp arc size in league with commercial projector lamps, making tuning the projector MUCH easier. This will mean higher efficiencies though the rest of the system.

My only doubt remaining is with the placement of the "puck" and if this will allow a reflector.

If it does not, then this loses the ~50% gain that we can get from the pro reflector, and makes this less desirable... However a 400W ~68,000 lumen lamp will produce more native lux with no reflector at all than the 400W MH lamp with pro reflector.

I am not to jazzed on these specs... I guess I am just to hung up on the life of the bulb... The cost at least for me fully outweigh's the life.

5reeds, that is the wrong bulb series. Those are for commercial apps, like the Panasonic RPTVs that come with them. You want the STAs for DIY.

The bulb isn't 250w the total system draw is. The brightest bulbs are ~185w.


Big plus.


It will not be possible to add a typical reflector. The puck inside the emitter is an RF waveguide and electric field amplifier that is needed to set the halides off. It completely encases the back half of the bulb.

There is more to the lumen numbers when comparing them. Initial lumen is a 360 deg measurement. With a typical 40,000lm bulb and reflector setup you are only going to use the lumen from the front and rear of the bulb, the top and bottoms are wasted light. At best we are only able to use about half the rated lumens of a typical MH bulb anyway. With the LiFi the light output is spread from a single plain in a 45deg cone.

Case in point, there is a diy PJ out there, already using the STA-40-02 right now with a common fresnel, condenser, and 15.4 LCD that is sitting at 200 ANSI after calibration. I figure with the right optics, at least a 25% increase from this should be doable.

Ok much better specs. I am very embarrassed.
