Q: If I replace a T12 fixture with a T8 fixture, can I claim de-lamping (lamp removal measures L-E6 or L-E7) for the lamps that were in the old fixture?
A: In this case, an incentive is not allowed. A de-lamping (lamp removal) incentive is not eligible when new fixtures are installed.
Q: How do I receive the lamp removal incentive?
A: Lamp removal (de-lamping) may be claimed if an existing fixture is made more efficient by removing the T12 lamps, magnetic ballasts, and unused lamp holders (tombstones) and replacing them with fewer T8 lamps/electronic ballasts. The number of lamps removed equals the pre-retrofit lamp count minus the post-retrofit lamp count. The quantity of lamps claimed for de-lamping may not exceed the quantity of new T8 lamps installed.
Examples:
Twenty 4-foot, 4-lamp T12 fixtures are retrofitted to 4-foot, 2-lamp T-8 fixtures. The 20 existing fixtures contained 4 lamps each for a total of 80 lamps. After the retrofit, the same 20 fixtures contain two T8 lamps each for a total of 40 lamps. (The existing T12 lamps, magnetic ballasts, and unused lamp holders were removed.) Therefore, 80 lamps minus 40 lamps = 40 lamps removed (de-lamped). Customer receives the install rebate under Measure L-E3 for 40 lamps (with electronic ballasts) and also receives the de-lamping rebate for 40 lamps under Measure L-E7.
Ten 8-foot, 2-lamp fixtures are retrofitted to 4-foot, 2-lamp T8 fixtures. The 10 existing fixtures contained twenty 8-foot lamps. After the retrofit, the same ten fixtures contain two 4-foot lamps. (For de-lamping purposes, one 8-foot lamp equals two 4-foot lamps.) Therefore, a de-lamping credit (Measure L-E8) is paid for one 8-foot lamp in each fixture for a total of 10, and an install credit (Measure L-E3) is paid for two 4-foot T8 lamps per fixture for a total of 20.
Q: How do I determine if my ceiling sensor qualifies for the $20 rebate (less than 500 watts) or the $44 rebate (more than 500 watts)?
A: Sensor controlling less than 500 watts example:
A ceiling or wall mounted sensor is installed in a conference room to control three fluorescent fixtures containing four 4-foot T8 lamps that are 32 watts each. Multiply 4 lamps x 32 watts = 128 watts per fixture. Then, multiply 128 watts x 3 fixtures. The total wattage controlled in the conference room is 384. Because the sensor is controlling less than 500 watts, the incentive is $20.00.
A: Sensor controlling more than 500 watts example:
A ceiling or wall mounted sensor is installed in a large office to control 20 3-lamp (28 watts each), 4-foot T8 fixtures. Multiplying 3 lamps x 28 watts = 84 watts per fixture. Multiplying 84 watts per fixture x 20 fixtures = 1,680 total watts. Because the sensor is controlling more than 500 watts, the incentive is $44. (Check current Express application to ensure rebate amount has not changed.)
Q: When applying for a rebate for new T8 or T5 fixtures (Measures LH-1 through LH-6), what documentation do I include with the completed application?
