3CCT Anti Glare LED Downlights with Watts Selectable 3 to 8 Inches

The ILED-DL-B T4 is an anti-glare recessed LED downlight with selectable wattage, built for commercial and residential ceilings where the light output may need to change after the fixture is installed. The deep-set optics and honeycomb diffuser keep glare low.

Range and models

Four sizes cover the range. The ILED-DL3-B T4 is 10W with 1,500 lm, 113mm in diameter by 60mm deep, cutout 90-100mm. The ILED-DL4-B T4 is 15W with 2,100 lm, 145mm by 74mm, cutout 120-130mm. The ILED-DL6-B T4 is 20W with 3,600 lm, 174mm by 87mm, cutout 145-155mm. The ILED-DL8-B T4 is 35W with 4,800 lm, 232mm by 111mm, cutout 195-210mm.

Selectable wattage

Wattage is switched on the driver before installation — 10W, 15W, 20W, or 35W. Lumen output follows the setting: 1,500, 2,100, 3,600, or 4,800 lm at 100 lm/W. This lets one fixture model cover rooms of different sizes, so an installer stocks fewer SKUs. The switch is on the driver, so it is set before the fixture is seated in the ceiling. Once set, the fixture runs at that level for its whole life unless someone reaches the driver again.

Light source

The fixture uses LM80-certified LEDs, a rating that tracks lumen maintenance over time. Color rendering index is above 80, which keeps most interiors looking natural. Color temperature is selectable between 2800K, 4000K, and 6500K via the 3CCT switch. 2800K suits warm residential and hospitality settings, 4000K suits offices, and 6500K suits detail work where crisp daylight tones help.

Anti-glare optics

The fixture is designed for low glare. The LED source sits deep inside the housing, and the honeycomb-patterned diffuser breaks up the light, so the fixture does not present a bright source at normal viewing angles. The result is soft, even light with less of the harsh spot that a shallow downlight leaves under itself. This matters in rooms where people spend long hours or look up — offices, kitchens, and reading areas.

Power and electrical

Input voltage is 220-240VAC. Power factor is above 0.9. The driver is built in, so there is no separate driver box to mount in the ceiling cavity. The body is aluminum with a PC diffuser, in a white finish. The aluminum frame handles heat passively — no fans, no moving parts, no maintenance. The IP42 rating covers normal indoor dry locations.

Control options

Four functions are offered, selected at order: DALI for networked building control, Triac dimming for standard wall dimmers, 0-10V for analog control systems, and an emergency version for buildings that need backup lighting during a power outage. The emergency option connects to a backup supply and needs separate wiring, so factor that into the install.

Installation

Spring clips hold the fixture in the ceiling cutout — no screws or brackets to align. Set the wattage and CCT switches on the driver before seating the fixture, since the driver is harder to reach once the trim is in. Connect the supply, push the housing up, and the clips seat it flush. For a new ceiling, cut the hole to the model’s cutout range and leave cavity depth for the housing.

Warranty and certifications

Warranty is 3 to 5 years depending on configuration. The fixture carries SAA, CE, and RoHS certifications.

Typical use cases

Offices use the 4000K setting for general work lighting, with DALI or 0-10V control for zoning. Kitchens and living areas use the 2800K setting with Triac dimming. Retail uses the 6500K setting and the selectable wattage to adjust output when displays change. Hotel rooms and corridors use the anti-glare optics to keep the light comfortable at rest height. Lecture halls use the even beam and selectable wattage to match room size.

Buyers choose the ILED-DL-B T4 for a few specific reasons:

Selectable wattage. 10W, 15W, 20W, or 35W is set on the driver before installation. One model covers rooms of different sizes, so installers stock fewer SKUs and adjust output on site.

Low glare. The deep-set source and honeycomb diffuser keep the fixture from presenting a bright spot at normal viewing angles, which matters in offices and homes where people look up.

Switchable color temperature. 2800K, 4000K, and 6500K are set with a switch. A room that changes use — kitchen by day, dining by night — changes CCT without changing fixtures.

Control options at order. DALI, Triac, 0-10V, or emergency. The fixture is built to match the control system already in the building, whether that is a networked DALI bus or a standard wall dimmer.

High output per watt. 100 lm/W across the range, with up to 4,800 lm from the 35W model for larger spaces.

The ILED-DL-B T4 fits several indoor settings where low glare and adjustable output matter:

Offices. The 4000K setting and low-glare optics keep screens and desks comfortable, and DALI or 0-10V control zones the light over workstations.

Kitchens and living areas. The 2800K setting gives a warm tone for meal prep and evening light, and Triac dimming adjusts the level from the wall switch.

Retail. The 6500K setting shows merchandise in crisp daylight tones, and the selectable wattage adjusts output when displays change.

Hotel rooms and corridors. The anti-glare optics keep the light comfortable at rest height, and the emergency option keeps paths lit during an outage.

Showrooms. The 8-inch model at 4,800 lm lights large display floors, with wattage dialed back where less output is needed.

Lecture halls and classrooms. The even beam covers teaching areas without harsh spots, and the selectable wattage adapts to room size.

Reading areas and libraries. The low-glare light keeps books and screens comfortable, and the 2800K or 4000K settings suit extended reading.

Bedrooms. The 2800K setting with Triac dimming gives warm, low-level light for evening, and the anti-glare optics keep the ceiling comfortable from the bed.

A few things to check before ordering:

Measure the existing hole. The four models need cutouts of 90-100mm, 120-130mm, 145-155mm, or 195-210mm. Measure the hole and the ceiling cavity depth before choosing — the bodies are 60 to 111mm deep.

Set the wattage before mounting. The driver switch selects 10W, 15W, 20W, or 35W. Set it before the fixture is seated — it is harder to reach once the trim is in.

Control function. DALI, Triac, 0-10V, and emergency are selected when the fixture is built. Match the option to the control system already in the building.

Color temperature. The 3CCT switch sets 2800K, 4000K, or 6500K on-site. If the room has other fixtures, set them all to the same CCT before locking in the switch.

Input voltage. This fixture runs on 220-240VAC only. Confirm the supply before ordering.

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