Product Overview

The Pentair MicroBrite Warm White LED Light | EC-620457 is a compact, energy-efficient underwater LED light designed for pools and spas. With 12V low-voltage operation, 14W LED power, and a 100-foot factory-attached cord, this light delivers soft warm white illumination for steps, benches, sun shelves, swim-outs, spas, and narrow wall installations.

MicroBrite lights are designed to install in compatible standard 1.5" pool wall fittings, eliminating the need for a traditional large light niche. The ultra-compact body is approximately 3.5" long, making it ideal for tight areas where full-size pool lights cannot fit.

This warm white model is perfect for customers who want a classic, relaxing white-light appearance instead of color-changing RGB effects.

Benefits

The Pentair EC-620457 MicroBrite Warm White LED Light gives pool owners a clean, elegant lighting upgrade in a compact form. Its warm white output creates a softer, more relaxing nighttime atmosphere compared with bright cool-white lights or color-changing systems.

Because the MicroBrite installs into compatible 1.5" wall fittings, it gives builders and remodelers more design flexibility than traditional large niche lights. It is especially useful for shelves, steps, benches, spas, and tight spaces where larger fixtures are not practical.

The 100-foot cord gives installers flexibility for longer equipment-pad or junction-box runs, while the 12V low-voltage design supports safer underwater lighting installation when powered by the correct transformer.

Compatibility Notes

The Pentair EC-620457 is designed for compatible 12V pool and spa lighting systems using standard 1.5" wall fittings.

Common compatibility references include:

• Pentair MicroBrite lighting systems
• Compatible standard 1.5" pool wall fittings
• Pentair automation systems
• Pentair Color Sync Controller setups where applicable
• Pool steps, benches, shelves, swim-outs, and spa applications
• Low-voltage pool/spa lighting systems using a compatible 12V transformer

Always verify wall fitting compatibility, transformer capacity, cord length, control method, voltage, and local electrical code requirements before ordering.

Installation Notes

This light should be installed by a qualified pool professional or licensed electrician. Underwater lighting involves electrical work around water and must comply with manufacturer instructions, transformer requirements, bonding requirements, grounding requirements, junction box placement, conduit rules, and all applicable electrical codes.

This is a 12V low-voltage light and must be powered by a compatible listed 12V pool/spa light transformer. Do not connect this light directly to 120V line voltage.

Before installation, confirm that the 100-foot cord is long enough to reach the approved junction box without splicing and that the total connected light load does not exceed transformer capacity.
