自从我们听说过Cree的新发展以来已经有一段时间了，但是他们最新的XHP系列LED势必会单独使用一些下巴掉落。新的Cree XHP终于有了一个代表某种东西，极端高功率的名称，而且从所有指标中，这是有史以来最亮的商业LED之一。
Remember how floored we were by the Cree XML several years ago for being able to run up to 10 watts and keeping more than 100 lumen per watt efficicency at 7 watts? The new Cree XHB obliterates those records with the ability to run at a mind-numbing 19 watts while still delivering more than 100 lumens per watt. That level of performance equates to more than 1900 lumens of bright white light emanating from a single minuscule 5 x 5mm light emitting diode.
Not only is the new class of Cree XHB LEDs incredibly powerful, they are also built on a platform of Silicon Carbide wafer which makes for a more affordable chip, but also increases the LED’s thermal tolerance. All that power packed into such a small package could lead to thermal management issues but Cree claims their new breed of LED can withstand higher temperatures and drive currents while still preserving an L90 of 35,000 hours – that means 90% of initial brightness of the LEDs will remain after four years of continuous use!
The Cree XHB LED and the new technologies it promises to introduces could lead to brighter and cheaper LED light fixtures for very high light applications, and with XHB, a true LED replacement for metal halide lighting could be on the horizon. However there are still plenty of technical hurdles for aquarists to overcome with the use of such powerful diodes, not the least of which is how to distribute all that light coming from such a small point source.
有希望的新Cree XHB二极管的样本尚未开始运输，我们几乎一无所知，即19瓦特二极管的颜色和垃圾箱是什么样的，或者它们的成本。新XHB的蓝色版本很可能会在白色版本之后出现，但与此同时，我们很高兴知道LED正在继续稳定的前进，以成为未来的轻型引擎。[[Cree]
