What Do I Do If My T12 Fluorescent Light Bulbs Have Been Outlawed and Are Now Unavailable?

Is it challenging to find replacement bulbs for your existing fixtures?  If you have been using T12 fluorescent or incandescent bulbs in your light fixtures, you may have already discovered that they are being, or may already have been, phased out.  T12 bulbs are fluorescent tubes that are 1½ inches diameter, and have been used commonly in numerous commercial, multi-family, and manufacturing facilities for many years.  Since T12s are no longer going to be available, you must act now to find an alternative bulb type.

Why are my light bulbs phased out?

In July 2012, the U.S. Department of Energy’s lighting mandate took effect. Fluorescent T12 lamps and ballasts were phased out and are no longer legal to be produced or imported. This mandate was passed due to federal energy efficiency regulations. 

What are my options?

If your goals are to maximize your lighting system investment, then your options for T12 replacement are:


  • Replace T12 bulbs and ballasts with either T8 or T5 bulbs and new compatible ballasts
    • Upside – cost effective, short term solution
    • Downside – T12, T8, T5 fluorescent tubes contain mercury and phosphorus which require special hazardous disposal


  • Replace your existing fixtures with new fixtures and LED lamps
    • Upside – maximum energy savings
    • Downside – initial cost and longer ROI


  • Replace incandescent bulbs with new Logical Green Solutions (LGS) LED lamps
    • Upside – maximum energy savings and option to upgrade at essentially no cost
    • Downside – you will need to find something to do with your extra time and money
