The ILED-DL-A D11 is a high-output recessed downlight for the ceilings that ordinary downlights cannot carry: retail halls, lobbies, stations, showrooms and other tall or large spaces where a 15W or 20W head would disappear. Four outputs run from 60W to 150W, all at 100 lumens per watt, and the bodies are correspondingly deep, from 230mm to 315mm, so the bigger heads hold their output without a fan or a driver box hanging behind the ceiling.
The four outputs
The ILED-DL6-A D11 is 60W, 6000 lumens, from a Φ190×230mm body into a Φ175mm cutout. The ILED-DL7-A D11 is 80W, 8000 lumens, Φ210×250mm into Φ195mm. The ILED-DL8-A D11 is 100W, 10000 lumens, Φ230×270mm into Φ215mm. The ILED-DL10-A D11 is the 150W, 15000 lumens, Φ260×315mm into Φ235mm. All four run from LM80 LEDs at 100 lumens per watt, so the higher outputs come from bigger light sources and bigger heat sinks, not from driving the LEDs harder, which is what keeps the colour and the lumen maintenance honest at this power level.
Light and beam
The beam comes in 38° or 60°, chosen at order time. The 38° head is the general workhorse for a mounted height of three to six metres, giving a defined pool of light on the floor. The 60° head opens up for broader coverage or for the lower ceilings in the range. Colour runs 2800K to 6500K with CRI above 80, which is the right level for retail floors, transit halls and lobbies where colour accuracy matters on the merchandise but the fixture is not doing critical colour work. Power factor is above 0.9.
The IP65 rating
This is the specification that separates the D11 from most commercial downlights: the IP65 rating makes it dust-tight and protected against water jets. In practical terms, the fixture survives a washdown, which puts it in running for food-retail ceilings, transit platforms, covered loading areas and industrial spaces where a standard IP42 downlight would fail the environment. The aluminum body is white or black.
Dimming and control
The driver options are DALI, Triac, 0-10V or DMX512, and the driver is the part to specify at order time. DALI ties the ceiling into a building management system, Triac runs from a plain wall dimmer, 0-10V takes an analog control signal, and DMX512 puts the heads on a lighting desk for venues that want the ceiling in the show. An emergency kit is available on the same body, which matters in transit and public buildings where the corridor lighting has to hold on a power cut.
Body and installation
The body is aluminum, recessed into the cutout on the mounting springs, and the depth of the can, 230mm to 315mm, is the space to check against the ceiling void before ordering. Electrical classification is Class I or Class II depending on the model, and input is 220-240VAC or the wide 110-277VAC version depending on the market. The spring-clip mounting is the same procedure across the range: cut the hole, wire the driver, push the clips up.
Where it gets used
Shopping malls and large retail floors, where 10000 or 15000 lumens from one head covers a bay that would otherwise need a grid of smaller downlights. Stations, airports and transit halls, where the IP65 rating and the emergency option are what the specification asks for. Showrooms and atriums with mounted heights of four to eight metres, where the 38° head keeps the beam defined at floor level. And industrial and food-retail spaces, where the washdown-safe IP65 body is the reason the fixture is on the drawing at all.
What is in the box
Each unit ships as a single downlight with the driver wired in, the mounting springs fitted and the terminal block ready to connect. The beam angle, the driver type and the colour temperature are the choices to confirm at order, because the fixture is built around them. The aluminum can and the diffuser are factory-assembled, and no lamp is bought separately; the LM80 LED array is part of the fixture.
