MHB_medIn a recent press release from Cree, Inc., the LED leader presents a new generation of high-power LEDs delivering improved performance, the XLamp® MH-B LED. It operates at higher temperatures than MP LEDS with no reduction in rated lifetime, using up to 26 times fewer LEDs than MP LEDs to achieve the same output. This is because the XLamp MH-B LED is built to use Cree’s high-reliability ceramic package technology. This enables an impressive 60% reduction in heat sink size and cost.

Cree notes: “the XLamp MH-B is optimized to simplify LED system designs for directional and semi-directional applications.”

The press release adds:

Featuring Cree’s EasyWhite® technology and a small 5-mm light emitting surface, the XLamp MH-B provides many system benefits over arrays of MP LEDs, including tighter beam angles, simpler optics, a more traditional appearance and easier color consistency. As a single LED, the XLamp MH-B LED delivers up to 830 lumens at 175 mA and can also be used in arrays to address higher lumen applications that require low cost and high reliability, such as high bay, outdoor area and downlights.

“The new XLamp® MH-B LED combines the reliability and manufacturability of Cree’s high power LEDs with the simplicity and performance of our CXA LED arrays,” said Paul Thieken, director of marketing, LED components. “MH-B introduces a new technology platform that gives customers the best of both technologies, while avoiding the limitations of mid-power LEDs.”

Looks promising. Cree has long been a leader in the energy-efficient, mercury-free LED lighting market. The company helps to do away with energy-wasting incandescent and even CFL lighting technologies. Learn move about Cree here.

    I can’t wait till this leads to even more efficient LED light bulbs for the house and oh how I’d love to have drop-in LED headlight bulbs in my city car (they make em, but not enough lumens yet)

  • Pat Campbell

    Anyone have ideas about using LEDs to attract moths?

    • Bob_Wallace

      Mine do.

      When a moth gets into the house it circles a lamp just as one expects to happen with an artificial light at night. Moon confusion.

      • Pat Campbell

        Thanks Bob. I’m thinking of using LEDs to build an outdoor attraction setup to take the place of my relative’s current setup that uses an auto battery and inverter.

        • Bob_Wallace

          Thinking on it some more, I commonly experience moths flying around my LED headlamp when I’m out using it.

          I don’t know if different color temperatures attract different types of moths or not. I’d be surprised if there was any significant difference between “shades of white”.

          Run a short test. Stick a LED flashlight outside on a dark night and see what happens.

          • Pat Campbell

            Good idea. I know some moth pollinated plants here in the PNW are white or whitish apparently to attract in low light conditions. There is a lot going on with animals I’m finding as I get older.

    These are a breakthrough for my kinetic LED sculpture designs/prototypes.

  • timbuck93

    Let me know when LED light bulbs accurately match the color temperature of the sun, dim really well, and can change to warmer color temperatures like Philips Hue, yeah, I’ll pay for it.

      Hey Tim,
      Go to home depot. You can get exactly the bulbs you are talking about. I’ve got bulbs in my house that are indistinguishable from incandescent. They have 2700K Phillips LEDs and many other brands with similar color ratings. Many positive changes have occured during the past 3 years.

    • StefanoR99

      Go to Costco and check out the high CRI Feit bulbs.

    • philofthefuture

      I’d definitely recommend the Home Depot CREE bulbs! I use the 60, 75, and 100 watt versions and they are all great. They look like incandescent bulbs, can be dimmed with standard dimmers and have a nice warm color temp.

      I’d also recommend the Eco-Smart flood replacements, they actually look better than the 65 watt floods they replace, are also dimmable with standard dimmers and have a warm temp. They are also marginally brighter than the incandescent floods. I’ve now done my whole house and the power savings are significant.
