- amend definitions;
- reference specific sections within industry test standards for further clarity;
- provide test methods for measuring coloring rendering index (CRI) for incandescent lamps and measuring the lifetime of IRLs;
- clarify test frequency and inclusion of cathode power in measurements for GSFLs;
- decrease the sample size and specify all metrics for all lamps be measured from the same sample; and
- align terminology across relevant sections of the Code of Federal Regulations relating to GSFLs, IRLs and GSILs.
