The Federal Energy Management Program (FEMP) provides acquisition guidance for fluorescent ballasts, a product category covered by FEMP efficiency requirements. Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified 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 efficiency requirements apply to instant start (IS) ballasts designed to operate 4-ft medium bipin (e.g., F32T8) or 8-ft slimline (e.g., F96T8) lamps; and programmed start (PS) ballasts designed to operate 4-ft medium bipin, 4-ft standard output miniature bipin (e.g., F28T5), or 4-ft high-output miniature bipin (e.g., F54T5HO) lamps. All other ballast types are excluded.
This acquisition guidance was updated in August 2015.
Find Product Efficiency Requirements
Federal purchases must meet or exceed the minimum efficiency requirements in Table 1. These requirements are stated in ballast luminous efficiency (BLE). A higher value indicates a more efficient product.
|Table 1. Efficiency Requirements for Fluorescent Ballasts|
|Lamp Type||# of Lamps||Ballast Type|
|Instant and Rapid Start||Programmed Start|
|F32T8||1||Suspended||BLE ≥ 0.87|
|2||BLE ≥ 0.93||BLE ≥ 0.91|
|3||BLE ≥ 0.93||BLE ≥ 0.91|
|4||BLE ≥ 0.94||Suspended|
|2||BLE ≥ 0.93||N/A|
|2||N/A||BLE ≥ 0.92|
|2||N/A||BLE ≥ 0.93|
BLE is the ratio of total lamp arc power (TLAP) to ballast input power. The ballast types in Table 1 can drive reduced-wattage lamps that save users additional energy.
Product performance must be determined in accordance with the new “active mode test procedure for fluorescent ballasts” found in the Title 10 of the Code of Federal Regulations (10 CFR 430, Subpart B, Appendix Q1).
Federal buyers can find product information (e.g., make, model numbers, and BLE) for fluorescent ballasts in DOE's Compliance Certification Database, which contains certification reports and compliance statements submitted by manufacturers for covered products and equipment subject to federal conservation standards. This database houses only certification records of current basic models that have been submitted within the past year, and is updated approximately every two weeks.
