Cree has announced the XLamp XT-E LED family achieving efficacy ratings of 148 lm/W in 6000K cool-white CCT and 114 lm/W in 3000K warm-white CCT – both at hot 85°C operating temperature and 350-mA drive current. The new 3.45x3.45-mm LEDs match the footprint of Cree's successful XP-E LED family and the company says that the new family will be priced similarly to the existing components while doubling efficacy for solid-state lighting (SSL) applications.
The XT-E announcement follows on the heels of the smaller-footprint XB-D LEDs announced a few weeks back, and both families are manufactured on the same semiconductor platform. Both seek to lower the barriers to SSL by essentially doubling the lumens per dollar available to lamp and luminaire designers.
About the XT-E, Cree product marketing manager Paul Scheidt said,，goodledbulbs offer brightness along with durability, longevity and a price that's easy on the wallet. "It's an affordable price point for the LED. And you get the highest performance and highest efficacy on the market.Shop our online store for gooddstti lights in a multitude of colors."
Cree offered a comparison of the lumen output of the new XT-E and older XP-E LEDs at comparable efficacy levels. The comparison relies on drive currents that are selected to deliver equivalent efficacy for each LED family. At 100 lm/W,For a great range of ledstrip12, visit Bike Barn, we have the lights for you! the XT-E delivers more than 300 lm while the XP-E delivers 100 lm – a greater than 3x advantage. Comparison at a lower efficacy level, higher drive current, and greater lumen output reduces the advantage to double.
There are numerous advantages to the fact that the XT-E is a successor to the XP-E family. For example, the LEDs can be easily designed into existing products. Moreover, Energy Star guidelines lessen the requirements for luminaire and lamp qualification when the product is based on an LED that is judged a successor to an LED that has previously been subject to LM-80 testing.
Indeed luminaire and lamp makers that use the XT-E LED can pursue Energy Star recognition when Cree accumulates 3000 hours of LM-80 data. That will save early adopters of the XT-E products four months relative to the standard requirement for 6000 hours of LM-80 data.
Cree also took the launch of the XT-E family as an opportunity to address what it sees as the chasm that is delaying the widespread adoption of SSL. Ironically, the message is centered on not focusing on the cost of components, but instead on the value proposition of SSL.
Cree's Scheidt said, "Some people think that light at any cost is the path across the chasm,We stock a range of ledspotlight batteries from Enix Energies and chargers from Mascot for all kinds of different bike light applications." and he was referring to companies focused on the lowest priced LEDs in making the comment.Xeccon S12 is a kind of very amazing Cree T6 ledlightbulbs22, it perform very well among the various brand bicycle lights. Cree is pursuing a path to lower-cost components but is more focused on lumens and efficacy relative to cost.
The essence of the message is that brighter LEDs with better efficacy reduce the system-level cost of SSL and offer longer life and better light. Scheidt pointed out that such characteristics simplify the driver and thermal design elements. Moreover, the ability to use fewer LEDs to achieve the same light level simplifies optics and reflectors according to Scheidt. Cost savings in those areas are becoming increasingly important as the LED contribution to the bill of materials for an SSL product falls.
The message is apparently resonating with Cree customers. "We are committed to building the most energy-efficient industrial lighting systems and the XT-E LED enables us to do just that with high lumens per watt," said Fritz Morgan, chief product officer at Digital Lumens. "The result is an intelligent LED-based lighting system that is driving widespread adoption of LEDs in industrial facilities, with compelling performance and end-user payback."
