® ENERGY STAR Program Requirements for Lamps and Luminaires Start Time Test Method September-2015 1 OVERVIEW The following test method shall be used for determining product compliance with start time requirements in the ENERGY STAR Eligibility Criteria for Lamps and the ENERGY STAR Eligibility Criteria for Luminaires. 2 APPLICABILITY This start time test method applies to all integrated and externally ballasted compact fluorescent lamps (CFL) and solid state lighting (SSL) lamps, light engines and luminaires. 3 DEFINITIONS Unless otherwise specified below, all terms used in this document are consistent with the definitions in the ENERGY STAR Eligibility Criteria for Lamps and ENERGY STAR Eligibility Criteria for Luminaires. Start Time: The time between the application of power to the device and the point where light output reaches 98% of the lamp’s initial plateau. Initial Plateau: The point at which the average increase in the light output over time levels out (reduces in slope). This can be determined mathematically or visually based on the lamp output trace. For examples, see section 9, below. 4 METHODS OF MEASUREMENT AND REFERENCE DOCUMENTS A) IES LM-66-14: 2014.
