Mouser Electronics announced it is stocking the new XLamp MK-R LEDs from Cree, which leverage the SC³ Technology next-generation LED platform to deliver up to 200 lumens-per-watt.
Cree XLamp MK-R LEDs are built on Cree's revolutionary SC³ Technology platform, delivering up to 200 lumens-per-watt (at 1W, 25ºC) enabling lighting manufacturers to create the next generation of high-lumen indoor and outdoor LED lighting systems. MK-R LEDs are available in EasyWhite color temperatures, providing the LED industry's best color consistency for designs that use only one LED. For systems that use multiple LEDs, MK-R enables manufacturers to use fewer LEDs while still maintaining light output and quality, which translates to lower system cost.
The innovative SC³ Technology platform leverages Cree's advanced silicon-carbide technology, features advancements in LED chip architecture and phosphor, and boasts a new package design to deliver the most advanced LED components in the industry. The XLamp MK-R is optimized for directional lighting applications and is a welcome addition to applications requiring high lumen output, a compact optical source, and a broad palette of color temperature and CRI values.
But jeeze, they took their time. Cree took the lid off these back when, December? How does Cutter get them from Cree 3 months earlier than a distributor in the U.S.? /rant
Thanks for the heads up, PPTK. I may build a bike light with one or two of these.
It drives me crazy that American manufacturers don't favor American businesses and people, at least not nearly enough. It's so hard to start something small. China makes it look so easy to source anything made there or to find someone to make it.
So what's this good for? The voltage tells me it'd be good for American automobiles. Aren't vehicles in Europe using a higher voltage system in their automobiles? I suppose it could work for flashlights with a 3S battery configuration, but it'd need to be a flooder with lots of these to take advantage of the low max output. Household light bulbs would be good too, and their description seems to favor that application.
Cree isn’t interested in selling to the automotive market. If you come to them as an automotive customer they will basically ignore you, or at best tell you they’re not interested and to go away.
I figured that, if only because there would've been chatter on the flashlight forums if they were using Cree's.
Would you know anything about the LED's being used, specifically for headlights, more specifically those used in the current Audi A8 and upcoming Toyota Corolla?
In the A8, because of a large number of LED's and small optics, I figured they were using something similar to the XR-E. That is, it can be focused with a small optics, but are not very powerful individually. I haven't seen how the Corolla headlights are configured yet, but they may be using a single LED on each side for the low beam.
I don’t have any specific firsthand details. Just what I’ve read or been told. I know Hella has made some of the LED headlights on the market like the Cadillac Escalade and Audi A8. Reportedly the Escalade headlights are Osram based. I’m not sure about the A8 but they’re probably the same. Osram, Lumileds, and Nichia seem to be the companies pursuing automotive business.
That is literally not too far from the truth. They're doing you a favor buying your stuff at a loss, just ask them.
Oh, and
E) If an automotive company audits you and decides you made more than what they think is fair (somewhere between -3 and +3 percent), they'll claw back your 'extra' profit.
F) An automotive company's terms and conditions almost always state that they can cancel all or part of a purchase order. This means they could ask you to quote a million widgets - you give them a price. They then give you a purchase order for a million widgets. After you deliver a hundred thousand of said widgets, they amend the purchase order to one hundred thousand widgets. Business with them is done. Never mind that you bought parts for a million widgets and hired staff to build one million widgets and moved into a new building that was larger because you had to deliver one million widgets. None of that matters.
