The Dept. of Energy has announced final regulations that set higher efficiency standards for residential and commercial lighting. The rules, issued June 26, apply to general-service fluorescent lamps (GSFLs) and incandescent reflector lamps (IRLs), which together account for about 45% of total lighting-energy use, DOE says. Under the rules, which take effect in 2012, electricity used in GSFLs would be cut by 15% and 25% in IRLs
DOE says the cost of the more efficient lamps would be as much as 13 times higher than current GSFL products’ prices and 47% to 64% higher than current IRL prices. But it says during new models’ lives, consumers would save as much as $8.66 per lamp for GSFLs and up to $7.95 per lamp for IRLs in energy costs.
