City Cabins to Shine Brighter
Home builder Martha Rose, president of Martha Rose Construction in Seattle, is adding arrays of LED lighting to her latest project in Seattle’s Queen Anne neighborhood. The projects, City Cabins, are all-electric powered homes.
More lumens equals more light
Rose mentions “sustainable building is all about doing more using less.” This type of think has influential in their selection of light bulbs for the “Cabins.” It just makes sense to use more efficient bulbs that use less wattage even though the cost is greater but once you look at the whole profile or payback for a LED bulb compared to a standard incandescent bulb it makes more financial sense.
A typical incandescent bulb would take 60 watts to produce 800 lumens where a CFL bulb would take up to 15 watts and a LED would take up to 12 watts to produce 800 lumens. When searching for high efficient LED bulbs, at the top of the list, we found the CREE that would produce 950 lumens using only 9 watts of electricity, the bulb retails for $79.95.
As the popularity of LED lighting increases the price will start to come down along with the passing of the 2007 the Energy Independence and Security Act (EISA) that was signed into law. The Department of Energy (DOE) issued new energy efficiency standards for fluorescent and incandescent bulbs. It will be phased-in 2012 through 2014 (California will begin one year earlier starting January, 2011)
City Cabins will use both CFLs and the next generation LED lighting for their lighting solution of their new homes.
