Product Overview

The J&J Electronics PureWhite LED Spa Light 21091 is a complete underwater LED spa light designed to deliver brilliant, cool-white illumination for compatible in-ground spas. Operating on 120 volts, this fixture includes a 50-foot factory-installed power cord and provides light output comparable to a traditional 100-watt incandescent spa light while consuming only approximately 13 watts.

Built with premium materials, the PureWhite fixture features a polished 316 stainless-steel face ring, a tempered Zero-Pixelation™ lens, and a fully encapsulated LED engine rated for up to 50,000 hours of operation. Its crisp 6500K cool-white light enhances water clarity and creates a clean, modern appearance while significantly reducing energy consumption compared to incandescent lighting.

Designed for installation in compatible full-size spa wet niches, the 21091 is a complete sealed fixture—not a replacement bulb. It is compatible with many Pentair®, Hayward®, and Jandy® spa niches, making it an excellent upgrade for older incandescent spa lights.

Benefits

The PureWhite 21091 provides the clean appearance of bright white LED lighting while using up to 90% less energy than a comparable incandescent fixture. Lower energy consumption helps reduce operating costs while generating less heat and extending service life.

Its advanced optical lens creates smooth, even illumination with virtually no visible pixelation, producing a professional appearance throughout the spa. The compact fixture depth also simplifies installation by improving visibility of the niche's bottom catch during installation and servicing.

Because the LED engine is factory sealed, there are no bulbs to replace, reducing maintenance while providing years of dependable operation.

Warranty & Compatibility

Installation Information

Disconnect all electrical power before installing or servicing the spa light. Verify that your existing lighting circuit is 120 volts and that the spa niche, conduit, junction box, grounding, and bonding comply with all applicable electrical codes.

Route the factory-installed 50-foot cord continuously through the conduit to the approved junction box. Do not cut, splice, or shorten the cord. Leave sufficient slack behind the fixture so it can be removed onto the spa deck for future maintenance.

Professional installation by a licensed electrician or qualified pool professional is strongly recommended.
