About Our Bulbs

Each TheraBulb® has a red colored coating. Inconsistencies in the red coating or the surface of the bulb —such as dimples, bubbles, areas of heavier or lighter coverage, darker or lighter color, and minor scuffs or scratches—may be more apparent when the bulb is lit, but will not affect the performance or life of the bulb.

A Note On Extending the Life of Your TheraBulb

Believe it or not, there are right and wrong ways to screw in a light bulb.

Screwing the bulb into the socket too tightly can cause it to burn out prematurely. This is because doing so can flatten the part of the socket (an angled brass tab) that makes contact with the bottom of the bulb, and it is this contact that allows the bulb to light up. If the tab becomes flattened, the bulb can burn out too soon.

The bulb should be screwed in just enough for it to stay in place when you release your grip on it. Once the bulb is in this position, stop screwing it in. Screwing it further can flatten the tab.
