That’s a lot of Lumens
Powerful Little Light: LED With 1,000 Lumens: Osram has developed a small light-emitting diode spotlight that achieves an output of more than 1,000 lumens for the first time. That’s brighter than a 50-watt halogen lamp, thereby making the device suitable for a broad range of general lighting applications. The Ostar Lighting LED, which will be launched on the market this summer, can provide sufficient light for a desk from a height of two meters, for example. Its small size also enables the creation of completely new lamp shapes.
The future is bright.

That’s a bright LED. I can’t wait for this to show on a projector. This could decrease the price of that device significantly.
Ooooh… Pretty…

Oops I should have said spam?
Does John’s “I get no Spam” count here to? Quick take a screen shot and send it to TWIT.
I can’t wait for LED light to come out that can replace HI-Bay factory light and office 4′ x 2′ Fluorescent Lights
Knowing the colour spectrum of LEDs… this won’t become a hit in most homes. But I can see it used as floodlights on industrial sites and other low-populated areas.
That’s amazing, can you imagine all the nifty tiny lights thats are going to hit the market that produce a huge amount of light. Imagine a spot light on your house that you can’t see when it’s off and can only see the light it’s producing when it’s on…
My imagination is spinning with ideas.
Very nice info.

If you really knew anything about LEDs you wouldn’t make such a sweeping statement.
Now we know that the compact flourescent makers are behind the politicos screaming to ban incandescent bulbs.These jokers are worried about the competition.
Doesnt the light source need to be about 5-10k lumens for a projection system? It seems like, between the color wheel, display system, and objective lens you are gonna lose about 50-60% of your lumens.
Not that this isn’t an interesting start. This will make awsome for flashlights.
#12 Have you been to a home depot, lowes, or target lately?
It is hard to believe there is a conspiracy by the CF makers given that the vast majority of CF bulbs for sale in the retail space are by small chinese companies rarely heard of. Has anyone bought a GE or Phillips CF lamp?
The chinese do really care which technology wins, they will be happy to make either for us.
#14 – Has anyone bought a GE or Phillips CF lamp?
Yes, I’ve got both brands in my arsenal of CFLs. The GE CFLs were made in Hungary and the Philips were made in China I believe. I really like the GE ones since they’re dimmable. They’ve been used daily for five years. We’re very happy with them.
13,
An LED-based display lighting system doesn’t need a color wheel, and a DSP-based light engine has nearly zero light loss.
#14 – I was given a Phillips CF lamp. Does that count?
(It’s really nice actually – a very soft color – almost like an incandescent.)
I use a Petzl Tikka headlamp and think its bright enough for camping at 40 lumens. I’d like to see what 1000 lumens would illuminate.
Some notes on this, which SHOULD have been in the dvorak/blog article:
This ‘LED’ is actually a package of SIX LEDs combined. So it may not be the big breakthrough the misleading headline implies.
Lumens/watt come to 75, fewer than the 130 some Japanese researcher has managed in the lab. I think fluorescents weigh in at 100 lumens/watt, so this will use more watts for the same illumination as compact fluorescents. Anybody want to bet on which will (also) be cheaper?
LEDs however do not contain the mercury that fluorescent lights do so that is a plus.
And finally they say this will come on the market this summer, which will be good.
I’m not against this product, I hope LED lights come soon, cheap, and take over the lighting world. But the ‘article’ that the dvorak-blog links to is little better than a company press release of the sort Mr Dvorak rants against, and the pointing bit above only contains the most-PR-bit of it, without any comment from Gasparrini to take note of these qualifications.

I’ll take some of the hit for this, I’m the resident opto expert. My writeup on the device is HERE.
Note that I address all your criticisms in my writeup.
If I weren’t just in Germany for CeBIT (I just flew back this afternoon) I would have asked my colleague (a recent addition to the staff, please be nice) to at least shift the link to his fellow editor’s writeup.
Now, to further address your comments, max lumens and deliverable lumens, especially with LEDs, are two different things. LEDs are more efficient than incandescents, but since they are on a substrate they have heat-dissipation issues. This LED array is a breakthrough in combining the light from multiple emitters in a single package that also handles the waste heat efficiently enough to deliver 500 lux at two meters. Those single LEDs you refer to are all playing specmanship.
IMNSHO, the best LEDs are currently made by an American manufacturer, Cree. Their emitters can acheive a continuous output of over 70 lumens with a drive current of 350 mA. Consistent light is far better than boasting you can burn out an LED and get a lot of peak output.
So, the next time you take issue with a post, address the editor that posted it, don’t assume John and the other editors vetted it before the fact.
At 1000 lumens, I’d have to wonder both about the color and heat output of the LED. I like LED flashlights, but unless they get the light color correct and bring down the heat load, I really don’t see this as replacing Fluorescent lights. LEDs don’t use less energy, they are a little more efficient at the perceived light output to power usage, and that’s about it. Also, more importantly in a flashlight, especially a combat light, the LEDs don’t break, at least I haven’t seen one break or burn out yet. It will allow different designs, but then again the heat load is going to be limiting factor, 60 lumen combat lights put out a lot of heat, I can’t really imagine what 1000 lumens would put out.

Then I assume the LED flashlights you like have the color temperature (how white light’s color is described) you desire.
This doesn’t even deal with RGB LED arrays, some now so small they can put all three emitters in a single 5-mm bullet that used to hold only one. Now, even you recognize I can get any color, including white at various color temperatures, with independently-driven red, green, and blue emitters?
I wish you people would stop looking at what was done last year to judge performance in an industry that is having breakthroughs almost every day.
