DALI LED Downlight Recessed Dimmable 12W Hole 90mm

The FC-D1 is a 12W recessed LED downlight built for standard ceiling cutouts of 85-90mm. It is used in homes, offices, retail, and hospitality spaces where a clean flush fixture with good color rendering is wanted.

Light source

The fixture uses a CREE COB (chip-on-board) LED. Color rendering index is above 90, which keeps fabric, paint, and merchandise colors looking correct. This matters in galleries, retail displays, and kitchens where color judgment is part of the work. Color temperature is set at order time from four options: 2700K, 3000K, 4000K, or 5000K. 2700K and 3000K suit homes and restaurants; 4000K and 5000K suit offices and work areas.

Power and input

Wattage is 12W. Input voltage accepts 220-240VAC or 110-277VAC, so the same fixture works across regions. There is no external driver box; the electronics sit inside the housing. Because the driver is built in, there is nothing extra to mount in the ceiling cavity — useful for retrofits where cavity space is tight.

Beam and optics

Three reflector lenses are available: 20°, 36°, and 60°. The 20° lens gives a tight pool for task lighting or accent on a specific object, such as a product on a shelf or a picture on a wall. The 36° lens is the middle ground for general room illumination and is the most common choice. The 60° lens spreads light wide for corridors, lobbies, and open areas. The recessed mounting keeps the source set back in the ceiling, which limits glare compared with a surface-mounted fixture at eye level. Reflectors are part of the fixture at order time; the beam angle is not field-swappable.

Construction

The body is aluminum. It doubles as the heat sink, so cooling is passive with no fan and no noise. The IP42 rating covers indoor use, protecting against small objects and water spray. Housing measures 98mm in diameter and 94mm deep, with a cutout size of 85-90mm. Check the ceiling cavity depth before ordering — the fixture needs roughly 94mm of clearance above the ceiling board, and the housing should not sit pressed against insulation, or heat builds up and shortens LED life.

Dimming and control

Four control options are available, chosen at order time: Triac dimming works with standard trailing-edge wall dimmers; DALI suits buildings with a control bus; Casambi is a Bluetooth-based wireless option controlled from a phone app; 0-10V works with analog dimming systems. An emergency version is available with a backup supply so the fixture stays lit during a power outage — the emergency option needs separate wiring, so factor that into the install. Because the control type is fixed when the fixture is built, match the option to the system already in the building before ordering.

Installation and maintenance

Installation is a drop-in job on a ceiling already cut to size: connect the supply, push the housing into the cutout, and the clips hold it in place. The LED source has no user-replaceable parts, and the sealed housing means there is no routine cleaning inside. Wipe the lens with a dry cloth if dust builds up; keep water away from the fixture. If the ceiling is being installed new, cut the hole to 85-90mm and leave cavity clearance above.

Typical use cases

In homes the fixture lights kitchens, bedrooms, and hallways with a flush ceiling look. In offices it provides high-CRI general light with 36° or 60° lenses. Retail uses the 20° lens for product spotlights. Hotels and cafes use the warmer CCTs with Casambi for scene control. Museums and galleries take advantage of the CRI above 90 for artwork. For corridors and lobbies, the wide beam covers the floor without bright spots, and the emergency option keeps paths lit during an outage.

Buyers choose the FC-D1 for a few specific reasons:

Color rendering. CRI above 90 from the CREE COB source. For retail displays, galleries, and kitchens, this is the difference between lighting that shows colors correctly and lighting that washes them out.

Four control options. Triac, DALI, Casambi, or 0-10V, picked at order time. A shop with a DALI system and a homeowner with a wall dimmer both get a fixture that matches how the room is actually controlled.

Fits standard cutouts. The 85-90mm hole requirement matches common ceiling prep. If the ceiling is already cut for a standard downlight, the FC-D1 drops in without re-cutting.

CCT set at order. 2700K through 5000K. There is no field switching to get wrong — the color temperature is fixed before it ships, so the whole install matches.

Emergency option. The backup version keeps light on during an outage, which matters for corridors, stairwells, and exit paths.

The FC-D1 recessed downlight fits several indoor settings:

Residential. Kitchens, bedrooms, and hallways with a flush ceiling look. The 2700K and 3000K options give a warm residential tone, and Triac dimming works with standard wall dimmers already installed in most homes.

Offices. Meeting rooms, reception areas, and open-plan floors benefit from CRI above 90 and the glare-limited recessed design. DALI or 0-10V control integrates with building management systems for scheduled dimming.

Retail. The 20° lens spotlights products on shelves and display tables, and the high CRI keeps merchandise colors accurate — important for clothing, food, and paint displays where the customer is judging color at the counter.

Hospitality. Hotels, restaurants, and cafes use the warm CCTs with Casambi app control to shift scenes between service and evening. The 60° lens covers dining areas evenly without hot spots.

Museums and galleries. CRI above 90 keeps artwork colors true, and the recessed, glare-limited design avoids reflections on glazed pieces.

Corridors and lobbies. The wide 60° beam spreads light evenly across walkways, and the emergency option keeps exit paths lit during an outage.

Quelques points à vérifier avant de passer commande :

Cutout size. The fixture needs an 85-90mm hole. If the ceiling is already cut, measure it before ordering. The body is 98mm in diameter and 94mm deep, so the cavity above the ceiling board must be deep enough as well.

Ceiling material. Plasterboard and wood ceilings both work, but the housing must sit clear of insulation. If insulation packs tightly against the aluminum body, heat builds up and shortens LED life.

Dimming option. Triac, DALI, Casambi, and 0-10V are selected at order time and cannot be swapped later. Match the option to the control system already in the building.

Beam angle. 20°, 36°, and 60° cover different jobs. Decide based on ceiling height and what the light needs to do before you order.

Color temperature. 2700K, 3000K, 4000K, or 5000K is fixed at order. If the room already has other fixtures, match their CCT.

Emergency version. The backup option needs separate wiring to a battery or emergency supply. If you are retrofitting into an existing ceiling, confirm the wiring path before installation.
