Product Description


The Certikin underwater light incorporates features absent from other underwater systems. The unique Micallef fittings at the niche and deck box enable the installer to fit non-standard conduit lengths (15m reels are available – part no. SPC464.).

Every light comes complete with a factory fitted clear polycarbonate safety cover (PU15C). Also available in blue, red and green, these can be purchased along with a compatible front plate to suit existing installations (PU15N).

Every light comes with a finishing fascia ring. The liner/shutter version clips onto the clamp plate hiding unsightly screw heads; the concrete version is easily fitted to the niche surround and is designed to cover tiling edges. The fascia rings are compatible with all Certikin underwater lights manufactured since 1968 and are available as spares for retro-fitting (Concrete – SPC475; Liner SPC476).

Bulb changing is now easier than ever with combination pozidrive / slotted screw heads, locating lugs and high-tech nickel plated inserts.

The niche is cleverly designed to angle the beam down by 5 degrees which means the lights can be positioned to accomplish the optimum effect in the pool without glare at the poolside.
