Top Quality Recessed SMD LED Downlight 3-8 inch 10-50W ILED-DL-A D2

The ILED-DL-A D2 is a recessed SMD downlight for ceilings that need a lot of light from a simple, clean fixture. The range runs from the 15W 3-inch head to the 50W 8-inch head, and the wide 90° beam is what makes it a general-lighting fixture rather than an accent light: one head covers a lot of floor, evenly, without pooling light under itself.

The four sizes

The ILED-DL3-A D2 is the 15W, 1500 lumens, a φ110mm body into a φ95mm cutout. The ILED-DL4-A D2 is 20W, 2000 lumens, φ145mm into φ120-130mm. The ILED-DL6-A D2 is 40W, 4000 lumens, φ190mm into φ165-170mm. The ILED-DL8-A D2 is the 50W, 5000 lumens, φ230mm into φ200-210mm. All four run at 110 lumens per watt from LumiLEDs SMD LEDs, so the bigger models get their output from a bigger light source, not from running the LEDs harder. That is the difference between this and a cheaper downlight that quotes a big wattage and a small lumen number, and it is the reason the range reads honestly on a spec sheet.

Light quality

The colour range is 2800K to 6500K, from a warm tungsten match to a cool daylight tone, with CRI above 82. The beam is 90°, wide and even, and the diffuser on the front spreads the SMD points into one smooth field rather than a ring of separate bright dots. Power factor is above 0.9, so the fixture does not drag the circuit, and the body is Class II double-insulated, so it does not need an earth at the fixture. Input is 220-240VAC or the wide 110-277VAC version depending on the market.

Dimming and control

The driver options are what make this range flexible across projects. It runs with Triac dimming on a plain wall dimmer, with DALI on a control bus, or with 0-10V on an analog dimming circuit, and the driver is the part to specify at order time because the fixture is built around the option chosen. An emergency kit is available on the same body, so a corridor or a stairwell that needs a held level on a power cut can use the same fixture as the rest of the ceiling rather than a different emergency unit beside it.

Body and installation

The body is aluminum with a PC diffuser, in white or black, and it recesses into the cutout on the spring clips. The deeper 6-inch and 8-inch bodies give the bigger models the heat sink area they need at 40W and 50W without a fan. The rating is IP42 or IP44 depending on the model, which covers a normal indoor ceiling and, on the IP44 versions, a bathroom ceiling above a splash zone. Installers tell us the spring-clip mounting is the part that saves time on a fit-out: cut the hole, wire the driver, push the clips up, done.

Where it gets used

Offices and commercial ceilings, where a grid of downlights has to carry the general light and the DALI or 0-10V dimming ties into the building management. Hotels, where the same fixture serves the corridor and the room, dimmed on Triac from the bedside. Retail floors, where the wide even beam covers the merchandising and the CRI above 82 keeps the stock reading true. And residential living rooms and kitchens, where one fixture range covers the whole job and the IP44 version goes over the wet zones.

What is in the box

Each unit ships as a single downlight with the driver wired in, the spring clips fitted and the terminal block ready to connect. The driver type, Triac, DALI or 0-10V, and the colour temperature are the choices to confirm at order, because the fixture is built around them. No lamp to buy separately: the LumiLEDs SMD array is part of the fixture, and the diffuser is fitted at the factory.

Why do buyers pick the ILED-DL-A D2 over the alternatives? Here is what we hear from customers:

Real output at the wattage. All four sizes run at 110 lumens per watt from LumiLEDs SMD LEDs, so the 50W head puts 5000 lumens into the room, and the range holds up when a specifier compares lumens rather than wattage.

One range, four driver types. Triac for a wall dimmer, DALI for a control bus, 0-10V for an analog circuit, and an emergency kit on the same body; the whole ceiling runs on one fixture family.

The wide beam carries the room. The 90° beam and the diffuser spread the SMD points into one even field, so the fixture works as general lighting rather than an accent, and fewer heads cover each square metre.

Class II, no earth at the fixture. Double-insulated construction simplifies the install where pulling an earth to every position is awkward, and the 220-240VAC or 110-277VAC input serves both markets from one range.

The IP44 versions go over wet zones. On the IP44 models, the same fixture that lights the bedroom goes over the bathroom splash zone, so a flat does not need a second downlight family.

The ILED-DL-A D2 is the general-lighting downlight of the range: the wide 90° beam and the diffuser are what make it a ceiling that lights the room, not a ceiling that spots the floor.

Offices and commercial ceilings. A grid of downlights that carries the general light, with the DALI or 0-10V driver tying into the building management and the 110 lm/W output keeping the energy budget down. The 20W and 40W heads are the usual sizes on a 600mm grid.

Hotels. The same fixture range serves the corridor and the room, dimmed on Triac from the bedside or on DALI from the reception desk, so the whole floor reads as one ceiling. The IP44 versions go over the en-suite wet zones.

Retail floors. The wide even beam covers the merchandising without a forest of heads, and the CRI above 82 keeps the stock reading true under the general light while the accent heads do the featuring.

Residential living rooms and kitchens. One fixture family covers the whole job: 15W or 20W heads over the living area, 40W heads over the kitchen bench, all on the same dimmer and the same ceiling line. The IP44 model goes over the wet zones without a second family.

Stations and high-traffic halls. The 50W 8-inch head puts 5000 lumens into a high ceiling position, and the emergency kit version holds the corridor level on a power cut, so the same fixture family runs the whole space.
