CaliMar CaliGlow Pro P-Series Nicheless LED Pool and Spa Light, 12V, 100 ft Cord, CMAR2L20W100P

The CaliGlow Pro P-Series is a 2 inch nicheless LED light for inground pools and spas, running in P-Mode so it speaks Pentair IntelliBrite. It puts out 900 lumens on 19 watts, the brightness of a much larger fixture from a body 5.48 inches long and 2.2 inches across the face, and it installs into standard 1-1/2 inch or 2 inch Schedule 40 PVC rather than needing a traditional niche.

The cooling is the reason it lasts

LEDs dim as they get hot, which is why sealed pool lights fade years before they fail. The core of this one is solid marine grade stainless steel, and machined grooves turn the fixture into a chimney: as it runs, cooler water is drawn from the bottom of the housing up across the heatsink. That passive circulation holds LED junction temperatures up to 40 percent below a sealed polymer housing, and the light still delivers over 90 percent of its original output at 30,000 hours.

14 programs from the wall switch

Fourteen programs: the SAM, Party, Romance, Caribbean, American, California Sunset and Royal shows, then blue, green, red, white and magenta as fixed colors, plus a color lock that freezes a show on any shade and a return that recalls it. Turn the switch off and back on the number of times that matches the program you want, one for the SAM show through twelve for magenta. The count is the same whichever program is playing. Thirteen cycles locks the current color of a show; fourteen returns to the last locked color. If you already run Pentair IntelliBrite lights on the same switch, these synchronize with them, so a mixed pool comes up in one color.

Before you order

This is a low voltage fixture and it needs a listed Class 2 transformer, 100 W or 300 W, stepping 120 VAC down to 12 to 14 VAC, on a GFCI protected circuit. With that transformer and the CaliGlow Pro 2 inch wall fitting the system is non metallic, so it needs no bonding or grounding under the current NEC. Installation is electrician work. The lens has to sit at least 4 inches below the water surface, and the plumbing needs 7 inches of vertical clearance between the top thread of the wall fitting and the bottom reducer.

In the box: the light on a 100 foot cord, an installation tool, a plaster cover and O-ring lube. Backed by a 3 year limited warranty from CaliMar.
