What is the difference in “Bi-Pin” and “RDC” tanning bed bulbs?
There’s no difference inside the bulb, however they do connect to tanning beds in very different ways. Bi-Pin bulbs have two pins that slide into the holder, and you then twist the bulb into place, whereas RDC (Recessed Dual Connector) bulbs spring in and out of the bulb holder. RDC bulb holders are much more expensive than B-Pin holders, and are therefore less common. Again, there’s no difference in the bulbs themselves, and there are no advantages in tanning with either lamp.
