Product details
The J&J Electronics 21091 is the PureWhite LED spa light in the S1W size, wired for 120V and supplied with a 50 foot cord. Its model code is LPL-S1W-120-50-P. It draws 13 watts and puts out 700 lumens, which J&J rates against a 100 watt incandescent spa lamp.
What the LED buys you
The trade against incandescent lighting is stark: J&J rates the PureWhite line at up to a 90 percent reduction in energy cost and as much as twenty times the lamp life, with the LED engine rated to 50,000 hours. For a spa light that runs most evenings, that is the difference between an annual lamp change and largely forgetting about it.
Build and light quality
The fixture is heavy gauge 316L stainless steel, the grade used where hardware stays wet. Inside, J&J's Zero-Pixilation lens system spreads the output so the water reads as one even field of light rather than a row of bright points. This unit is cool white at 6500K, the daylight tone. The warm white version at 2700K is a separate part for anyone who wants the softer incandescent look.
Before you order
Check three things: that your niche and circuit are 120V rather than 12V, that 50 feet of cord reaches your junction box with slack to spare, and that you want cool white rather than warm. The fixture is tested and approved for swimming pool use by Intertek ETL and carries a three year limited warranty.
