Fluorescent tanning bed light bulbs require a tanning bed ballast to provide and regulate power. If the tanning bed electrical ballast is not properly working then it needs to be replaced with a tanning bed transformer that is suited to the particular lamp. There is not a great deal of electrical skill needed to replace a ballast except the ability to follow safety procedures (such as turning off power) and a general understanding on reading wiring diagrams and using basic tools, such as wire strippers and crimps. If you are not comfortable with electrical work, it is always best to call a qualified electrician.
