Warm white Luxeons coming August

"New Luxeon Product Will Be First Warm White LED To Enter Mass Production; CCT of 3200K and CRI of 85+ Will Broaden Use of LEDs in General Lighting"

Ugh! I don't want "warm" white for a flashlight. I want the color of the sun, of daylight -- something clean and crisp like my Arc LS or my Space Needle II. I have enough dingy-looking incandescents.

I just wish they'd master plain ol' white. /ubbthreads/images/graemlins/wink.gif

I'm interested. I'll make all sorts of lamps out of the things.

I just hope they got the green out before they added the red, otherwise it will be brown /ubbthreads/images/graemlins/icon15.gif !!

They were probably supposed to be plain ol' white

Another batch of off-whites, don't throw them out we'll just call them "warm" /ubbthreads/images/graemlins/wink.gif /ubbthreads/images/graemlins/grin.gif

I'll bet that if the new phosphor produces a pleasing enough output, the current 'blue' or 'blue-green' phosphor will be phased out in a year or two.

If you can't fix it, call it a feature - or a new product !

Yield problems notwithstanding, this new LED model is going to use a different phosphor formulation. The key here is the high CRI (color rendering index). The cold blues are 70 whileas the new warm units are 85. This means these units will be better for distinguising colors. So you can see this is not a greenish white LED.

We will have to compare some units side by side to see if it improves the visibility of objects in the beam.

i think it could be a very good thing...

some people don't like leds, because the prefer the warmer tones of their incan.

So long as they're milky whites or vanilla whites, with no green or violet shade, they're good to go in my mind.

All this time I've been wondering how they would sell off their huge inventory of off-white greenies... /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

With Nichia's 5 mm "warm" or as they termed it, "incandescent" white, luminous output ws sacrificed to get the color. I hope this isn't the case with Lumiled. Unfortunately there is a large market that will forgo lumens for "warmth".

Why are so many of you guys so negetive about this? Follow this logic:

More 'white' (higher CRI) LEDs than the current ones (think of them like early flourescents--efficient, but the color was horrible so people didn't adopt them) so they are useable and look *good* in more applications. This spurs demand. Demand spurs supply and *development* of newer/cooler LEDs.

Now, we agree, at least, that *that* is a good thing, right?

We never want to say that there is something that an LED can't do better than an incandescent, right? /ubbthreads/images/graemlins/smile.gif

CRI of 85 huh? We'll see.. I have a hard time believing it will look better and render colors better than the current good (not greenies) LS's. /ubbthreads/images/graemlins/icon3.gif Like Mr. Bulk said, I guess they have to get rid of their bad stock somehow. /ubbthreads/images/graemlins/yellowlaugh.gif

<Lumileds Marketing Guru at big important meeting with LumiLEDs president>
We will tell everyone that we are re-formulating the phosphor to get a "warm white", and then we can FINALLY get rid of all these green LS's nobody wants!!! We don't have to prove it, right? Just do a press release, everyone believes those...

Nichia's white LEDs were said to have a CRI of 85, but there was no mention of what bin code they were. BS I think (color bin B, brightness bin S) but I'm not 100% certain.

Hey Craig, was that a joke? If so, haw!

yes, i do recall the "warm" nichias being less bright...

was there also a beam pattern issue? i don't really remember...

Sounds like someone spilled another Pepsi in the "control room" at Lumileds... /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

Stay away from "Globe Tech" white LEDs, they have an off white center and that obnoxious fluorescent green-brown "baby poo" color around the beam center. /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/icon15.gif
Yucky. Pee-green is far better... Even the crappy overpriced ones fom Radyo Sharq are better in both color and brightness. /ubbthreads/images/graemlins/icon23.gif

Funny! hehe... don't think Craig purposely wrote that, though!
