A classic 4" housing for new construction
The RF401 is a 4" recessed housing designed to be installed while the ceiling is open, in new construction or in renovations where the drywall has been removed. It forms the body of the pot light: it is fastened to the framing, receives the supply wiring, and holds the lamp socket above the ceiling plane. The visible part, the trim, is added once the ceiling is finished.
Medium base socket: bulb flexibility
The housing has a medium base socket, the familiar screw-in socket used by standard household bulbs. That means you can use the LED bulb that best suits each room, choose a warmer or cooler colour of light, and replace it in seconds when needed. The name specifies a 120V, 50W rating; always choose a lamp that respects the housing and trim markings.
Installation
Lay out the lights on the floor or with a laser, transfer the marks to the framing and fasten one housing at each location while the ceiling is open. Run and connect the supply cable according to the installation instructions and your local electrical code, and keep the required clearances from insulation, framing, ducts and plumbing. Have a licensed electrician make all connections. Once the drywall is finished, install a compatible 4" trim and the bulb.
Choosing the trim
The trim defines the final look and the light effect: a baffle trim reduces glare and gives a soft, even look; an adjustable trim lets you aim the light at artwork, a fireplace or a kitchen island; a black or white finish can blend with the ceiling or create contrast. Pick trims made for this 4" housing so the fit is clean and flush with the ceiling.
Where it is used
Kitchens, hallways, bathrooms, closets, basements, home offices and small commercial spaces such as boutiques, clinics and restaurants all benefit from compact 4" recessed lights. Count one RF401 per location, add the trims and bulbs, and you have a complete, easy-to-maintain lighting solution.
