Future electricity price trends and a 3% discount rate are from Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis – 2021: Annual Supplement to NIST Handbook 135 (NISTIR 85-3273-36). Lifetime Energy Cost: Calculated as the sum of the discounted value of the annual energy cost and assumed product life of 12.1 years or about 49,000 hours. Source: Federal Government Energy/Water Use and Emissions in 2019 in Comprehensive Annual Energy Data and Sustainability Performance. Final Rule Technical Support Document: Energy Conservation Program for Consumer Products and Certain Commercial and Industrial Equipment: General Service Fluorescent Lamps and Incandescent Reflector Lamps.Īnnual Energy Cost: Calculated based on an assumed electricity price of $0.088/kWh, which is the average electricity price at federal facilities. Source: DOE Office of Energy Efficiency and Renewable Energy. Some ballasts are manufactured with the capability to drive multiple lamp configurations so the same ballast can have different input power ratings depending on the ballast or lamp configuration.īallast Power: Power to the ballast only, not including power used by lamp, determined using BLE and TLAP, (shown in watts).Īnnual Energy Use: Based on the test method referenced in 10 CFR 430, Subpart B, Appendix Q1, for an instant-start ballast driving two F32T8 lamps, operated 4,065 hours/year with an average start of 3 hours (shown in kilowatt-hours).
ENCORE ENERGY SAVING BALLAST PLUS
TLAP: Based on the wattage used by an instant-start electronic ballast plus two F32T8 lamps (shown in watts). 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.īLE: The ratio of total lamp arc power (TLAP) to ballast input power. Department of Energy's (DOE) Compliance Certification Database, which contains certification reports and compliance statements submitted by manufacturers for covered products and equipment subject to federal conservation standards.
ENCORE ENERGY SAVING BALLAST CODE
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).įederal buyers can find product information (e.g., model numbers and lamp efficiency) for fluorescent ballasts in the U.S. The ballast types in Table 1 can drive reduced-wattage lamps that save users additional energy. Efficiency Requirements for Fluorescent Ballasts A higher value indicates a more efficient product. These requirements are stated in ballast luminous efficiency (BLE), which is the ratio of total lamp arc power (TLAP) to ballast input power. Federal purchases must meet or exceed the minimum efficiency requirements in Table 1.
