The Federal Energy Management Program (FEMP) provides acquisition guidance for light bulbs, a product category covered by ENERGY STAR. Federal laws and requirements mandate that agencies purchase ENERGY STAR qualified products or FEMP designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.
FEMP’s acquisition guidance and associated ENERGY STAR efficiency requirements for light bulbs are technology neutral, meaning that any light source that meets all the criteria can qualify. However, ENERGY STAR’s product specification requirements are limited to the following lamp shapes:
- Omnidirectional lamps (ANSI standard shapes A, BT, P, PS, S, and T)
- Decorative lamps (ANSI standard shapes B, BA, C, CA, DC, F, and G)
- Directional lamps (ANSI standard shapes R, BR, ER, MR, and PAR)
- Nonstandard form lamps (e.g., bare spiral and mini spiral, bare twin tube, triple tube and quadruple tube, covered and covered with reflector).
In addition, these lamps must have integrated ballasts or drivers and be able to connect to the electric power grid with ANSI standard base types E26, E26d, E17, E11, E12, GU24, GU5, or GX5.3. All other lamp types are excluded.
This acquisition guidance was updated in August 2015.
