Fluorescent lamp ballasts.
CFR · 2024-01-01 · US · Title 10
(a) (2) For each basic model of fluorescent lamp ballasts, a sample of sufficient size, not less than four, shall be randomly selected and tested to ensure that— (i) Any represented value of the energy consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of: (A) The mean of the sample, where: Or, (B) The upper 99 percent confidence limit (UCL) of the true mean divided by 1.01, where: (ii) Any represented value of the ballast luminous efficiency, power factor, or other measure of the energy efficiency or energy consumption of a basic model for which consumers would favor a higher value must be less than or equal to the lower of: (A) The mean of the sample, where: (B) The lower 99 percent confidence limit (LCL) of the true mean divided by 0.99, where: (iii) The represented value of average total lamp arc power must be equal to the mean of the sample, (b) (2) Pursuant to § 429.12(b)(13), a certification report must include the following public product-specific information: The ballast luminous efficiency, the average total lamp arc power, the power factor, the number of lamps operated by the ballast, and the type of lamps operated by the ballast ( (c) (2) Round power factor to the nearest hundredths place. (3) Round average total lamp arc power to the nearest tenth of a watt.
