Spa light flickers on and off

The light in the spa comes on for 30-60 seconds, goes off for about a minute or so, then comes back on, then off again etc.. The light in the attached pool stays on. The breaker does not blow, only the light flickers. Any suggestions as to what is causing it and/or how to repair it?

Here are a couple of things...

What make/model is the light. Is there an internal over temp switch that could be tripping and auto resetting?

Is the light controlled by a photo cell? If the light comes on at dusk, but the light in the spa casts enough light on it's own photocell it could turn itself off. Then back on. Off. etc...

Could the lights from the pool or surrounding area lighting be illuminating the spa photocell?

Spa Light

I'm not sure what make and model the light is. It's just a 100W pool light. Probably a reflector flood R20. I do know that it is not controlled by a photo cell. There is a regular light switch to turn it on and off. Same thing for the pool light, but it has it's own switch and is not flickering on and off.
