Integrated light-emitting diode lamps.

CFR · 2024-01-01 · US · Title 10

(a) (1) (i) The general requirements of § 429.11 (a) are applicable except that the sample must be comprised of production units; and (ii) For each basic model of integrated light-emitting diode lamp, the minimum number of units tested must be no less than 10 and the same sample comprised of the same units must be used for testing all metrics. If more than 10 units are tested as part of the sample, the total number of units must be a multiple of two. For each basic model, a sample of sufficient size must be randomly selected and tested to ensure that: (A) Represented values of initial lumen output, lamp efficacy, color rendering index (CRI), power factor, or other measure of energy consumption of a basic model for which consumers would favor higher values are less than or equal to the lower of: ( ( (B) Represented values of input power, standby mode power or other measure of energy consumption of a basic model for which consumers would favor lower values are greater than or equal to the higher of: ( ( (C) Represented values of correlated color temperature (CCT) of a basic model must be equal to the mean of the sample, where: (D) The represented value of lifetime of an integrated light-emitting diode lamp must be equal to or less than the median time to failure of the sample (calculated as the arithmetic mean of the time to failure of the two middle sample units when the numbers are sorted in value order) rounded to the nearest hour. (2) The represented value of life (in years
