Submersible Luminaires
UL services covers submersible luminaires intended for installation in fountains and similar water-containing vessels not intended to accommodate the complete or partial immersion of persons. Additional services apply for luminaires intended for use in swimming pools, spas, hot tubs and other vessels intended to accommodate persons, see Luminaires and Forming Shells (WBDT).
This category also covers submersible junction boxes intended for use with submersible luminaires and other submersible fountain equipment.
Luminaires investigated for operation only while submersed in water are marked "Submerse Before Lighting," or with equivalent wording, and such marking is visible after installation of the luminaire.
