The media relations group for Oak Ridge National Laboratory just released more information about recent field tests by ORNL of a new roof and attic system that keeps homes cool in the summer and prevents heat loss in the winter. The system is explained in the graphic embedded above (click to expand). In addition, I’ve included some graphics below to illustrate more of what the system looks like and how it saves energy.
Although the new, four-inch CR4-575L is available at Home Depot, the updated, six-inch CR6 is not at this time. So, as Doug pointed out in our comments, it may be worthwhile to post a comparison of the existing CR6-575L with the updated CR6-800L. Before doing that, note the new CR4-575L has similar specs to the existing CR6-575L with the main difference being one is made for a 4″ housing and the other is for a 6″ housing. Here’s a head-to-head of the popular six-inch CR6 downlights.
I was walking the aisles of Home Depot when I happened upon a screaming deal for the L Prize winning LED light bulb by Philips. This is the bulb, you may recall, that caused a national fuss over the reported price tag of $60. Turns out you can get the same bulb just five months later for the more reasonable price tag of $40 at Home Depot right now.
In July 2012, Cree announced brighter LED downlights in the CR Series. The CR4-575L fits a 4″ housing and delivers 575 lumens, 90 CRI, 2700 Kelvin, dimming up to 5%, and 50,000 hours while only using 9.5 watts of energy. The CR6-800L fits a 6″ housing and delivers 800 lumens, 90 CRI, 2700 Kelvin, dimming up to 5%, and 50,000 hours while only using 12 watts of energy. Both are Energy Star qualified and they’re available in either the Edison or GU24-type bases. The CR4 sells for about $53, and the CR6 sells for about $55 (both at EarthLED).
Today Hulger announced the new Baby Plumen 001, a designer CFL light bulb that tracks the original Plumen 001. It’s a smaller 9-watt bulb that’s meant to replace a 40-watt incandescent. The 220-volt version is available today through Plumen.com, while the 120-volt version, which is compatible in North America, will be available later this year. The Baby Plumen lasts about 8,000 hours and has a color temperature of 2700 Kelvin.
