LED's are the closest thing to the Jetson's that our vocation will see with respect to illumination, it is the future. IMO
It's like seeing a new car or even listening to your favorite artist new release, do you like it or not, well OK always debatable, but it is what it is, I don't think this one product will ever go away nor what one will see or hear.
They can be used in many enviroment's or as required with the correct controls, IE they are dim-able. But that'd would be a second party. Cree is pulling a Joe Jackson and "Stepping Out".
There's three big players in LED's they are Sylanvia, Phillips, and Cree. All three are trying to do things to fit their companys' model.
The cost ratio equation is also always debatable. Its funny how the cost can
calcutated and justifiable in large environments and not be quailifiable in small ones.
If one thinks about this life time that an a LED even existing verses a filament element, well there's no comaprison! What the LED can do in so many ways has already made it the future winner.
I'm sorry that the article only presents a press release.
