DOE Considers New Definition for General Service Lamps

The U.S. Department of Energy will hold a public meeting on 21 October to discuss and receive comment on a proposed definition for general service lamps to be published in a forthcoming notice of proposed definition and data availability. The meeting will cover the proposed scope of the GSL definition; the DOE’s approach to analysing the 22 lamps exempted from the statutory definition of general service incandescent lamps, including available sales data; challenges manufacturers may have in meeting the statutory backstop requirement of 45 lumens per watt associated with the lamps meeting the GSL definition that will apply beginning in January, 2020; options available to the DOE and/or manufacturers to help manufacturers transition to the backstop requirement; and any other issues relevant to the scope of the GSL definition.  

U.S. law requires the DOE to conduct two rulemaking cycles to evaluate energy conservation standards for GSLs. For the first rulemaking cycle, the DOE was required to initiate a rulemaking no later than 1 January 2014 to evaluate standards for GSLs and determine whether exemptions for certain incandescent lamps should be maintained or discontinued. The agency was also required to consider a minimum standard of 45 lm/W. If the DOE fails to meet all applicable legal requirements or the final rule from the first rulemaking does not produce savings greater than or equal to the savings from a minimum efficacy standard of 45 lm/W, sales of GLSs that do not meet the minimum 45 lm/W standard will be prohibited beginning on 1 January 2020.
