Replacement Photocell

This replacement dusk-to-dawn photocell is the same component included with all of our complete Underwater Fish Light systems. It serves two essential functions: completing the electrical circuit that supplies power to the ballast/transformer and automatically controlling when the system turns on and off based on ambient light levels. Designed with simple and reliable technology, photocell failures are extremely rare. However, if a failure does occur, the system will typically remain on continuously and operate during daylight hours without shutting off automatically.

If you are unsure whether this is the correct replacement part for your system, please contact us at 941-391-5846, and our team will be happy to assist you.
