Federal test procedures for lighting get updated quietly, and each update changes what a quoted lumen or watt figure is actually measured against. For buyers writing specifications, the procedure matters because it decides which numbers are comparable across suppliers.
What the procedure governs
A test procedure defines how power, light output and efficacy are measured for a portable luminaire — a floor or table lamp. When the method changes, the same physical product can report a slightly different number, not because the lamp changed but because the ruler did.
Why buyers should care
If you compare two quotations using figures from different procedure versions, you are comparing different measurements. The fix is to require that every supplier quote against the current federal method, so your evaluation set is consistent.
- Require the test method version on each spec sheet
- Compare efficacy only between suppliers using the same version
- Keep the listing scope aligned with how the lamp is actually sold
Compliance versus certification
A test procedure is not the same as a safety listing. The procedure tells you how to measure; the listing tells you the lamp is legal to sell. Both belong on the file, and the procedure version belongs next to the performance numbers.
A performance number without its test-method version is not comparable to any other performance number.
Frequently asked questions
Does an updated procedure make existing lamps illegal?
No. It changes how new measurements are taken and reported. Lamps already listed remain valid; new quotations should simply state the current method.
What should I add to a purchase order?
Require the quoted performance figures to be measured under the current federal test procedure, with the version noted, so suppliers are compared on equal terms.
