Are lamps equivalency claims restricted to the exact shape and wattage combination that appear in the referenced ANSI documents? Follow

The referenced American National Standards Institute (ANSI) documents may not include all of the wattage and shape combinations that are available in the marketplace, particularly since federal energy efficiency standards have gone into effect. EPA recommends that product brand owner partners choose product equivalencies that are recognizable by consumers and are commonly found in the marketplace.

For example a bare spiral CFL that does not fit the maximum overall length (MOL) and maximum overall diameter (MOD) of an ANSI standard A-lamp, but produces 850 lumens, may claim equivalency to a 60 Watt lamp.

For another example, 90W BR40 lamps were commonly available in the market prior to the 2009 US Department of Energy rulemaking for IRLs, making it a familiar wattage and shape combination to consumers, but one that is not specified in ANSI documents.  For the purposes of ENERGY STAR, equivalency claims to 90W BR40 lamps are allowed under the Lamps specification.
