Hot tub lights
Most hot tub lights run on 12 volts from the control system. Match a replacement bulb or LED by voltage, connector type, and how it mounts in the housing. If water is getting in, replace the lens or its gasket as well as the bulb.

Questions
Can I replace my hot tub bulb with an LED?
Usually yes, if the LED is made for the same voltage and socket. Some LED systems need a matching controller, so check what your control system supports.
Why is my hot tub light not working?
The bulb has failed, the light fuse on the board has blown, or the connector is corroded. Check the bulb first.
Is a leaking light lens a serious problem?
It should be fixed promptly. It loses water and lets moisture reach the bulb and wiring. A new lens or gasket usually solves it.
