Fluorescent Luminaires

Last Updated: 09/19/17

A complete lighting unit consisting of lamp(s) and ballast(s) (when applicable) together with the parts designed to distribute the light, position and protect the lamps, and to connect the lamp(s) to the power supply

Life Cycle Cost Savings

For most applications, energy efficient fluorescent luminaires have the lowest life-cycle cost. For example, FEMP has estimated that an installation of 100 recessed lensed 2-by-4-foot luminaires each using three F32T8 lamps could save the typical federal agency $4,300 in energy costs over the life of the luminaries, by using luminaires with FEMP-designated efficiency levels as compared to a less efficient model. The estimated savings for "best available" luminaires is even larger: $8,600 per 100 luminaires over the life of the installation.

An efficient product is cost effective when the energy costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Federal purchasers may assume that Energy Star-qualified products and products meeting FEMP-designated efficiency requirements are life-cycle cost effective. On its Purchasing & Procurement page, Energy Star offers MS-Excel-based calculators to estimate how much money and energy you can save purchasing ENERGY STAR fluorescent luminaires.

Additional Guidance
FEMP energy efficiency requirements for fluorescent luminaires used in commercial and institutional buildings include requirements for ceiling mounted luminaires and suspended luminaires. Specialized luminaires, like recessed linear and round wall washers, are excluded. Residential fixtures are covered by Energy Star specifications.
