There are four consideratons:

  1. It is a 2-pin tube (which is by far the most common type).
  2. It replaces 48” florescent tubes.
  3. It is a “hybrid” type”, which means it will work with most ballasted and non-ballasted fixtures (download a complete list of compatible ballasts).  When unsure, hire an electrician to bypass the ballast (see our wiring diagram).
  4. It is UL approved as a T8 (T8 means 1-inch diameter tube). It may also be used in T10 and T12 fixtures (which accommodate 1.25” and 1.5“ diameter bulbs respectively), provided a UL rating for T10 or T12  is not required (by fixture or user).
