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.

Questions about this item

What dimming standard does the 9.9 W downlight use and what is the lowest level it reaches in practice?

It works with standard TRIAC or ELV dimmers and typically dims down to around 10 % of full output without flicker.

What ceiling opening or junction-box size is required for the 4-inch square trim?

The fixture fits a standard 4-inch round housing or a 4-inch octagon junction box; the square trim covers the opening completely.

How is the screw-base adapter wired during retrofit installation and what step is often missed?

Connect the adapter’s line, neutral and ground to the house wires, then snap the module into the adapter; the step often missed is securing the ground screw to the metal box.
