Q. Upgrading T12 Bulbs


1. Why are T12 fluorescent systems being phased out?
T12 lamps and magnetic ballasts have been outdated by the far more energy-efficient T8 and T5 systems now available. As a result of this phase-out, production of 70 percent of T12s was discontinued on July 14, 2012.

2. What type of savings can I expect?
Select from a variety of upgrade scenarios that could result in energy savings as high as 45 percent, with attractive 1- to 3-year simple paybacks.

3. Why are these rebates only available for a limited time?
As of Jan. 1, 2013, a new (higher) minimum efficiency standard will be established and required. Rebates will be based on this new standard as the baseline and not on the old T12 efficiency standard. It will become common practice to remove less efficient T12 systems; therefore, changing out T12 systems will be the customer’s only option for maintaining their lighting system, since these general purpose T12 lamps and ballasts will no longer be produced.

4. Will any T12 systems continue to be manufactured?
Although they may be less efficient and more costly to operate, the following T12 systems will continue to be available:

  • T12 ballast designed to dim fixtures more than 50 percent of their full light output.
  • o
  • T12 ballast driving 8-foot HO fixtures designed for outdoor advertising.
  • o
  • T12 ballast designed and labeled for use in residential applications.

5. Should I gradually change out my T12 magnetic ballast system or should change them all at once?
In order to get maximum energy savings and utilize existing incentives to their fullest, a project should upgrade the lighting system as a whole, not as individual fixture upgrades.
