Surface Mounted SMD LED Downlight 9-30W ILED-DL-B S1

The ILED-DL-B S1 is a surface-mounted SMD LED downlight with a round housing, built for ceilings where a recessed unit cannot fit. The housing mounts directly onto the ceiling face, so it works on solid concrete slabs, on top of plywood decking, and in rooms with shallow voids. The LM80 LED source delivers around 100 lm/W, and the 120° beam spreads light wide for general illumination rather than tight accent work. Because nothing is buried in the ceiling, the unit is also easier to service later: the driver and source are reached without pulling a housing out of a hole.

Modelos

Four models cover the range:

• ILED-DL3-B S1 9W: 900 lm, housing 100mm in diameter by 68mm deep
• ILED-DL4-B S1 12W: 1200 lm, housing 100mm in diameter by 80mm deep
• ILED-DL6-B S1 24W: 2400 lm, housing 170mm in diameter by 100mm deep
• ILED-DL8-B S1 30W: 3000 lm, housing 212mm in diameter by 120mm deep

The 9W and 12W models share the same 100mm housing, so a room can mix the two outputs without changing the mounting detail. Output scales with housing size, which also gives the larger models more surface for heat dissipation. The 9W model is the choice for small rooms and accent spots; the 30W model is the one for open workshop areas and higher ceilings.

Óptica y color

The beam angle is 120° on every model, which is a wide wash suited to general lighting in corridors, utility rooms, and open areas. It spreads light evenly across the floor, so it works where a narrow spot would leave dark corners. Color temperature ranges 2800-6000K, so the fixture covers warm interior tones and cooler work-area tones. CRI is above 82, which is a standard level for general indoor lighting. The effective output is around 100 lm/W, so the light delivered per watt is consistent across the range.

Construcción

The housing is aluminum with a PC component. Bodies come in white or black, chosen at order. The IP rating is IP42 or IP44, so the fixture is fine for dry indoor rooms and the higher grade adds protection against splashes. The electrical classification is Class I. The round body sits flush against the ceiling, and the finish is fixed at order, so the color should be confirmed before delivery.

Mandos y sistema eléctrico

Input is 220-240VAC or 110-277VAC with power factor above 0.9. Control is chosen at order: DALI dimmable, Triac dimmable, or 0-10V dimmable. The DALI version links into a building management system; the Triac version works with standard wall dimmers; the 0-10V version uses a low-voltage control signal. Each control type is a separate driver build, so it should be decided before ordering rather than changed on site.

Instalación

Because the fixture mounts on the surface, there is no cutout to make. Fix the housing to the ceiling with the included fittings, wire the driver, then close the unit. On a concrete ceiling, mark the mounting holes and use the correct anchors for the substrate. Always switch off the supply at the breaker before wiring. The mounting face is flat, so an uneven ceiling may need packing behind the housing to sit level.

Dónde va

The S1 suits shops, workshops, corridors, and kitchens where a recessed unit is not possible. It is a common choice for concrete-slab ceilings in commercial buildings, and for retrofit jobs where the ceiling void is too shallow for a recessed housing. The wide 120° beam makes it a good general-purpose unit rather than a spotlight.

Warranty and certifications

The ILED-DL-B S1 carries SAA, CE, and RoHS certification, and is covered by a 3-5 year warranty. If the project needs certification documents on file, they can be requested from the sales team.

The ILED-DL-B S1 is a direct answer when a downlight has to mount on the surface instead of into a hole.

• No cutout needed. The housing fixes to the ceiling face, so it works on concrete slabs and shallow voids where a recessed unit cannot go.
• Wide beam. The 120° spread covers a room evenly, which suits general lighting in corridors and open areas.
• Efficient output. Around 100 lm/W from an LM80 LED source keeps energy use low for the light delivered.
• Round family look. Four models from 9W to 30W share the same housing style, so outputs can be mixed in one room.
• Choice of finish. Bodies come in white or black, so the fixture can match light or dark ceilings.
• Flexible control. DALI, Triac, or 0-10V dimming, selected at order.
• Documented compliance. SAA, CE, and RoHS certification, with a 3-5 year warranty behind the unit.

For surface-mounted round downlights, this is the range we point buyers to first.

The ILED-DL-B S1 suits buildings where the ceiling cannot take a recessed fixture. In shops and showrooms with concrete slabs, the surface housing mounts directly and the 120° beam spreads light across the room for general lighting. In workshops and utility rooms, the 24W and 30W models give strong even light without needing a cutout.

In corridors and lobbies, the round body reads as part of the ceiling design, and the white or black finish can match the interior. In kitchens and food counters, the CRI above 82 keeps colors close to natural, and the IP42 or IP44 rating covers dry and splash-prone areas.

The 9W and 12W models share the same 100mm housing, so a row can mix outputs without changing the mounting detail. The 24W and 30W models cover larger rooms with 2400 lm and 3000 lm respectively. For open-plan spaces, the wide beam keeps the light even across the floor. For retrofit work, the surface housing avoids cutting into a slab, which keeps dust and debris out of occupied rooms, and the wiring is reached from below without opening the ceiling.

A few points to check before you order the ILED-DL-B S1.

• Body size. Housings run from 100mm to 212mm in diameter, with depths from 68mm to 120mm. Check the projection below the ceiling if headroom is tight.
• Finish. Bodies come in white or black, fixed at order. Confirm the color before delivery.
• Control choice. DALI, Triac, or 0-10V dimming is selected at order. Changing control type after delivery means a different driver.
• Voltage. Confirm whether the project runs 220-240VAC or 110-277VAC and state it with the order.
• IP grade. IP42 or IP44 is chosen at order. State the grade with the order if the location is splash-prone.
• Mounting surface. The housing fixes to the ceiling face. On concrete, use the correct anchors for the substrate, and pack the housing if the surface is uneven.
