Thanks to both of you for taking the time to reply. I have the owners manual for the light but it does not cover repairing it (other than changing the bulb). I'm sure I can figure it out once I have the time to remove and dissassemble it. My guess is that only a Pentair tech would have access to a repair manual or technical bulletin (if any exist) for these lights. But I figured it couldn't hurt to ask.
Thanks again.
