I ran across these new LED bulbs from Sylvania in a local store the other day. The packaging was a little vague about it's benefits other than reducing blue glare and providing a higher CRI. I thought about buying one to try it out but they only came in packages of 2 or more so I changed my mind and decided to read about it first.
They've published a lot of new-age marketing hype about these lamps, however I finally found a document that offered some actual details about their tech. They claim that their blue LEDs have multiple quantum wells to produce a more broadband blue as opposed to a narrow spike of blue. They also hinted at a special phosphor mix although they really didn't offer much detail about this. The spectral chart shows a pretty contiguous spectral content that falls off towards the red end of the spectrum, so not flat but not full of gaps either.
Has anyone tried these? They're being offered in a 2700k version and a daylight version. I think they're claiming 90 CRI.
