Cooper Halo SMD4S6930WH 4" Square Surface Mount Recessed Lighting 3000K 600 Lumens 9.9W Dimmable

4-inch Square Surface Mount Downlight

The Cooper Halo SMD4S6930WH is a complete LED recessed retrofit kit that fits a standard 4-inch housing diameter. It delivers 600 lumens at a warm 3000K colour temperature with a high 90 CRI for accurate colour rendering. The dimmable module suits residential rooms where adjustable light levels are required. Ultra low profile design keeps the fixture close to the ceiling plane.

Junction box or housing installation

A screw-base adapter is included so the unit connects directly to an existing medium-base socket inside a 4-inch recessed can or a standard junction box. The square white surface-mount trim sits flush for a clean architectural appearance. Wide light distribution provides even illumination across work surfaces and living areas without visible hotspots. Dimmable driver works with compatible wall dimmers for smooth output control.

Retrofit replacement for older 4-inch recessed trims

This kit upgrades legacy incandescent or CFL downlights using only 9.9 watts while matching the form factor of a 4-inch housing. The jump is worth it when a builder or homeowner wants higher efficacy, longer service life and better colour fidelity without cutting new ceiling openings. It is not suited for installations that require a round aperture or a larger housing diameter.
