On January 2, 2018, the U.S. Department of Energy (DoE) issued a final rule related to energy standards for rough-service and vibration-service incandescent lamps. The effective date for the rule is January 25, 2018. In effect, the rule is there will be no energy standards rulemaking.
The Energy Independence and Security Act of 2007 established energy efficiency standards for 40-100W incandescent and halogen general-service lamps. Starting 2012 for 100W, 2013 for 75W, and 2014 for 40W and 60W, covered lamp types had to become about 30 percent more efficient or be prohibited from manufacture and import. Five lamp types were exempted, including rough-service and vibration-service lamps. The law prescribed a backstop provision–basically, if sales of exempted lamps surged in response to general-service lamps being phased out, they would become subject to rulemaking. DOE analyzed the market and determined sales of these lamps have not crossed the threshold requiring rulemaking.
