www.nichia.co.jp/products/led-smd-powerled.html Here are some Nichia has under development. Don`t know if they can compete with the LS...but they have deep pockets and years of experiance...and they don`t like Lumiled Co. Prepare for the attack? Or not.
New Nichia LED`s a threat to the LS?

i love compition it makes stuff more avalable
Hmm, the link does not work...their calling them the Jupiter series. Maybe someone sharper than I can post a link...I did a search for "nichia led" and found it right away.
Ok, here www.nichia.com ...go to SMD LED`s and click.

I guess we'll just have to wait and see. Personally, I welcome competition.

Too bad...no specs. I wonder what they're up to, though. It looks like the whole series involves varying the height of the dome - possibly for different angular distributions.

Didn't someone post a beamshot comparing a nich 2w to a luxeon 1w? Was it McGizmo? I couldn't find that link again.

It was on McGizmo's site. The Nichia 2W is brighter than the LS 1W but then again, it should be. I can't say it looks twice as bright though.

all the other high flux leds are still way behind lumileds /ubbthreads/images/graemlins/frown.gif
I have some warm white samples - and I wouldn't mention them in the same sentence as the Luxeon High Domes.
Nichia is nearly a year late with production on these and I'm guessing it's because they are so inferior that they don't want to put them out there against the Luxeon high domes.
My samples emit light over an 80 degree angle. Looking at the beam it's got a distinct blue spot in the middle that changes to white, then a light yellow, followed by a deep buttery gold, and finally distinctly orange at the edge. They are basically back in the dark ages of glopping a big uneven mound of phosphor over their nice blue LEDs and hoping for the best. I'm sure their regular whites have a similarly polluted beam appearance. Don't get me wrong - I use Nichia 5mm's extensively and like them a lot. Nichia just has a lot to learn about high power LEDs.
A recent presentation Lumileds made at a LED lighting seminar mentioned Nichia and Lumileds were sharing technology. Nichia could benefit from Lumileds' phosphor coating technology, and Lumileds might benefit from Nichias expertise in light extraction from the LED die.
We'll see what happens.... /ubbthreads/images/graemlins/popcorn.gif
EDIT - Rereading this it sounds pretty negative. I have nothing against Nichia, but was surprized at just how bad the light emission was from the samples I received. Having a lot of experience with their fine 5mm whites - it was just a big letdown compared to Luxeon high domes.
