For one I am not a lover of LED's. I am very much in favor of good lighting , saving energy and protecting the environment. LED's are non of the above, IMO. They are not perfected yet and I have seen hundreds of them go bad within months. Very much like the CFL deal where the public got sold a bill of goods. How many million CFL's are sitting in garbage cans not properly disposed of and how many millions of these never lasted a month.
There is no standard on either of these products so manufacturers are pumping them out like candy and they are poor quality. Those that are good quality cost a small fortune and most homeowners will never see their value from these things. Maybe someday but not now. Even the sales people will tell you it is not cost effective for a residence.
I am not a lover of LED's either.
I've heard numerous horror stories from my vendors(whole batches burning up at a rate of 30-50% within the first month)
1: LED's manufacturers push the light output of the LED by pushing the voltage that an LED can take to the maximum. If you apply 27V to a computer core instead of 2.7V you'd get a SUPER COMPUTER. Problem is, it'll burn out fast. Same thing with LED's. Why do you think a 2" LED bulb has this 7" radiator around it? I have seen an LED lamp with a FAN behind it. SURE, BRIGHT, EXTREMELLY BRIGHT. But what happens when the cooling conditions are not the same as the test conditions? Do they test these lamps under normal conditions?
2: MYTH: LED's do not create heat: FALSE. Again, why do they need that big A.. radiator around them if they don't create heat??? YEAH, they're not hot when you touch them, because the heat dissipates fast enough through the radiator, but it still creates heat. And I could bet anything it creates more heat than CFL's
3: LED's seem brighter. ARE NOT necessary brighter. Pushing the kelvins into a lamp gives you the illusion of being brighter when you look directly at it. Most LED's seem to run at 4K PLUS Kelvin. Our church is still testing the LED idea, we put a few LED lamps 25 some feet in the air, which were supposed to be brighter than CFL's(MUCH BRIGHTER). Sure enough, the LED's are spots, the CFL's were floods. Took my light tester and measured 17 FC directly under the light with the LED. Moved 1-2 feet and the light level dropped to 8-10 FC. With the CFL I was getting a good 11-12 FC on a 2-3 feet radius
