These lamp lengths are usually printed right on the lamp and looks something like this: “F71-T12-100W BP.”

Reflector type lamps will contain an “R” like the following:
“FR71-T12-100W.”

The two different types of lamp ends are Bi-Pin (marked as “BP” as shown in the first example) and RDC.

The Bi-Pin lamps have two pins on either side and are installed by sliding these pins into the lamp holders and then twisting the lamp once or twice.

RDC lamps have a black cap at the end. These lamps are installed by pushing the lamp into one “spring loaded” lamp holder and setting the other side right in. There is no twisting the lamps with RDC’s.

When replacing your tanning lamps, it is very important to know the size (F59,F71,F72,F73, etc) and the style (RDC or Bi-pin) of your lamp. If this information is not available either on the lamp itself or on the tanning bed (lamp information can usually be found on a sticker on the canopy of the bed), then you will need to have the make, model and year of the tanning bed when calling your distributor.
