If you elect to change out lamps only, rather than fixtures, T5 and T8 lamps replacing T12 lamps earn a per/lamp rebate if they have electronic, high-frequency ballasts with five-year or longer warranties, a power factor of ≥ 0.90, and total harmonic distortion of less than 20%.

Installing T5 lamps under low ceilings can cause excess glare, so check with a lighting professional under these conditions. When installing T8 lamps but no occupancy sensors, use instant-start ballasts. If you install occupancy sensors, use programmed-start or programmed rapid-start ballasts for longer lamp life.

There is even a de-lamping (removing some of your bulbs) rebate, for permanent removal of T12 lamps, ballasts, and unused lampholders from existing fixtures. This rebate can be combined with a rebate for replacing lamps, as long as you do not claim more de-lamping credits than the number of replacement T5 or T8 lamps/ballasts. Wineries must evaluate remaining light levels for safety and adequate work lighting once de-lamping or replacing lamps is completed.

To qualify for the utility rebate, the complete fixture must be changed to a hard-wired fixture for pin-based (not screw-in) CFL lamps. New ballasts must be electronic, with a power factor of ≥ 0.90, and total harmonic distortion of less than 20%.

Wineries can use complete new fixtures, or retrofit kits for pulsestart metal halide fixturing. Replacements must be equipped with pulse-start metal halide lamps, and either magnetic or electronic ballasts.

Eligible units are hardwired fluorescent fixtures with electronic ballasts, pin-based lamps, and manufacturerintegrated occupancy sensors. If the area is occupied, the fixture should be set to operate at full output, and during unoccupied periods the fixture should operate at reduced light output and wattage.

Interior induction fixtures are also included for rebates, under terms described above.

Wineries can replace existing reflector-type, directional lamps or fixtures (incandescent, PAR halogen, or PAR halogen IR) for rebates. Qualifying replacement fixtures are ceramic metal halide, with wattage of 39 watts or lower. Be sure the fixtures are compatible with existing lighting controls.

Qualifying replacement lamps include integrated ballast ceramic metal halide PAR lamps (25-watt, 10,500 hours of rated lamp life), and screw-in CFL 14-28 watt reflector lamps with the Energy Star label.

Exit signs qualify for lighting rebates, if they are new, LED (light emitting diode), electroluminescent, or photoluminescent, replacing incandescent or CFL-lit signs. The new exit signs must have usage levels less than 5 watts and minimum product life of 10 years (or be Energy Star qualified), and meet local fire codes.

Channel letter signs can also be changed for more efficient models using either LED retrofit kits, or complete LED replacement signs. The new sign qualifies for a rebate if it uses 20% or less input power compared to the sign replaced.
