Luminaires must be installed in accordance with the National Electric Code (NEC) and local codes. Failure to do so may result in serious injury and/or damage to the luminaire.

To avoid electrical shock, turn off the power at the circuit breaker before starting your installation project.


  • Turn off/unplug and allow fixture to cool before replacing lamp.
  • Lamps get hot quickly! Contact only switch/plug when turned on.
  • Do not touch hot lens, guard or enclosure
  • Keep lamp away from amterial that may burn
  • Do not touch the lamp directly at any time. Use a soft cloth. Oil from the skin may damage the lamp when illuminated.
  • Do not operate luminaire fitting with a missing or damaged cover.

NOTE: Always use UL recognized wire connectors.


The most common cause of damage in submersible pond & fountain lights are due to user error during installation. Therefore it's crucial to choose high quality fixtures that offer multiple safeguards from user error and a strong build construction to maximize the fixture's longevity.

    Underwater Lights

    These are well sealed and a good quality. My electrical engineer said they were a major upgrade from the original lights that these replaced. And, thought it was possible that these would last a very long time. The old ones (purchased in 2008 from Quality lighting) leaked. These are sealed very well.

    Happy with the service and quality of the products.

    Posted by Andrew, Architectural Accents of Naples, Naples, Fla. on Mar 15th 2018

    We did receive the shipment and we were happy with the service and the lights themselves were okay. However we usually get the PUD707 lights and wanted to get more light for a large commercial fountain so we ordered the PUD 77 light. We had to modify the bases a little. This is not a problem on the PUD 707. All other aspects of the lights were fine the two lenses was a nice touch and they look good. We would like to see heavier bases on the PUD77 lights. Thank you for your interest in our opinion. (PUDX77)

    Good service and quality

    Once it was determined that the bulb had shaken loose during shipping, the light does exactly what we were looking for.
