Product Overview

The Pentair MicroBrite White LED Light | EC-620429 is a compact, energy-efficient underwater LED light designed for residential pool and spa applications. Its ultra-small nicheless design allows it to fit into places traditional pool lights cannot, making it ideal for steps, sun shelves, swim-outs, benches, spas, and tight wall areas.

Operating on 12V low-voltage power and using approximately 14 watts, the MicroBrite White LED delivers bright, clean white illumination while helping reduce energy use compared with older incandescent lighting. With a 100-foot factory-attached cord, this model is a strong choice for installations where the equipment pad, junction box, or transformer is farther from the light location.

The EC-620429 installs into compatible standard 1.5" pool wall fittings and does not require a traditional full-size light niche, giving builders and remodelers more design flexibility.
