What is U (Universal)?

  The industry code “U” stands for “Universal” and indicates the proper burn position for a given lamp. A bulb coded “U” can be mounted and operated in any position: vertical, horizontal, or at any angle.

Why Does Burn Position Matter?

  Every lamp is coded with a specific burn position. The consequences of disregarding burn position vary from decreased efficiency to poor light quality to safety concerns. It’s always in your best interest to heed the manufacturer’s instructions.
