4-Inch Square LED Surface Mount

The Philips Lightolier S4S830K7AL is a 4-inch square LED downlight designed for surface mounting on ceilings or walls. It delivers 650 lumens of 3000K warm white light while consuming 10 watts. The aluminium finish provides a clean, architectural appearance with a flat lens and narrow flange. This fixture suits residential and commercial spaces wanting a low-profile recessed look without a housing can.

Wet Location Listing and Shallow Depth

The unit carries a wet location listing, making it suitable for bathrooms, covered outdoor soffits and other damp environments. Its 5/8-inch profile eliminates the need for an Air-Seal recessed housing or fire-rated boxes, reducing material and installation complexity. The integrated driver connects directly to a standard junction box, so no separate housing cavity is required. Installers must ensure the mounting surface can accommodate the fixture’s wiring compartment.

80 CRI at 3000K Colour Temperature

The light source renders colours at 80 CRI, which is adequate for general illumination but may not satisfy tasks demanding high colour fidelity such as art display or detailed visual inspection. Buyers who need a higher colour rendering index or a different colour temperature should consider other models. The fixed 3000K output cannot be adjusted in the field.
