I can't find any information on the CRI (color rendering index) of these particular bulbs, but Cree was making a bulb a couple years ago that was rated over 90, which is generally considered excellent. If these are comparable, they're a fantastic deal, particularly given the warranty.
- ars 14y agoCRI is 80: http://www.homedepot.com/catalog/pdfImages/36/36f3e188-bdb8-40ac-a7ad-ef9ae6c129b6.pdf http://www.homedepot.com/catalog/pdfImages/36/36f3e188-bdb8-... which is slightly worse than most CFLs. Note that 80 is the minimum legal to qualify for Energy Star.
- msutherl 14y agoThat's a deal-breaker. Don't buy this bulb. It will make everything look awful.
- lusr 14y ago"CRI is not a good indicator for use in visual assessment, especially for sources below 5000 kelvin (K)." Bulbs in question are 2700K and 5000K. Does your conclusion still hold? [1] http://en.wikipedia.org/wiki/Color_rendering_index http://en.wikipedia.org/wiki/Color_rendering_index
- thisone 14y ago2700k isn't bad, but 5000k? That's grow light spectrum. I've seen people complain over the "too whiteness" of 3000k bulbs never mind 5000k.
