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.
