Surface Mounted vs Recessed Downlight: Which Should You Choose?

A downlight is a compact ceiling light that throws its light downward. It comes in two installation styles: recessed, where the body sits inside a hole in the ceiling, and surface mounted, where the whole fitting sits on the ceiling. The right choice depends mostly on your ceiling. This guide compares the two for Singapore homes, with real cut hole sizes and prices.

What is the difference between surface mounted and recessed downlights?

A recessed downlight is fitted into a cut hole, so only a thin trim shows and the light sits flush with the ceiling. A surface mounted downlight is fixed onto the ceiling surface with no hole, so the body is visible. Recessed needs space above the ceiling, usually a false ceiling. Surface mounted works on almost any flat ceiling.

Which is better: surface mounted or recessed downlight?

Neither is better in every room. Recessed downlights give the cleanest look and suit homes that already have, or are adding, a false ceiling. Surface mounted downlights are the practical choice when there is no ceiling cavity, when you want to avoid cutting holes, or when you may want to change the lights later.

A recessed light sits in line with the ceiling, which gives a minimalist style and can make a room feel more spacious. A surface mounted light needs no hole, causes minimal damage to the ceiling it is fixed to, and is easier to replace with another size or design. It also gives you more freedom over where the lights go, because you are not limited by an existing cut hole or by the false-ceiling frame.

Can you install downlights without a false ceiling?

Yes, if you choose surface mounted downlights. They are fixed directly to the ceiling, so they work on a bare concrete ceiling. HDB flats usually have a concrete ceiling unless a false ceiling has been added. Recessed downlights need a hollow space above the ceiling, so on bare concrete you would first need a false ceiling or a boxed-up section.

A surface mounted light still needs a lighting point at the spot where you want it. If the point is already there, for example from an old ceiling light, a licensed electrician can usually swap the fitting without new wiring. If you want lights in new positions, new wiring is needed. In Singapore, the Energy Market Authority (EMA) says that the addition, extension or replacement of lighting points must be carried out or supervised by a Licensed Electrical Worker. For an HDB flat, that is a licensed electrician, and you can ask to see their licence card before work starts.

How much ceiling space does a recessed downlight need?

A recessed downlight needs a ceiling cavity deeper than the part of the fitting that goes into the hole, plus room for the cable and any driver box. The depth needed varies widely by model, so check the "recessed distance" and "cut-out" on the product's data sheet before cutting.

As an example, the Philips 12W recessed downlight data sheet (PDF) for Singapore lists a recessed distance of 50 mm, an overall height of 21 mm and a ceiling cut-out of 150 x 150 mm. It is rated IP20, which means it is meant for dry indoor areas. Leave some free space around any recessed fitting and do not cover it with insulation or other material, so heat can escape.

What size downlight do I need? Reading cut hole sizes

Match the cut hole: measure the hole in your ceiling and choose a recessed downlight with the same cut hole size. The cut hole is the width of the hole (its diameter for round lights), and the outer size is the trim that covers its edge. A hole that is too big cannot be covered by a smaller trim.

These are the cut hole and outer sizes of our round and square LED Downlight range (230V, 2-year warranty, prices in November 2026):

For the square version, please confirm the cut hole shape and size with us before cutting a new hole. For smaller holes, our round LED Downlight XMT Series fits cut holes of 75 mm (6W), 90 mm (9W) and 110 mm (12W). Surface mounted lights have no cut hole, so you choose them by overall diameter instead. In our range, surface mounted downlights are sold as the Surface Mounted Ceiling Light, which comes in 100 mm (6W), 155 mm (12W), 205 mm (18W) and 280 mm (24W).

Is a downlight the same as a ceiling light?

Not quite. A downlight is a small fitting that directs light downward, usually used in groups. A ceiling light is one larger fitting in the middle of the room that lights the whole space. A surface mounted downlight sits between the two: it mounts like a ceiling light but is sized and spaced like a downlight.

Many Singapore homes combine them, for example a main ceiling light in the bedroom and downlights along the corridor. Browse our LED ceiling lights and LED downlights to compare sizes. If you want lights you can aim at a wall or a display, track lighting is another option; see our guide to the types of track lighting.

How do you choose between recessed and surface mounted?

Choose by ceiling first, then by room. Where there is a false ceiling, recessed downlights give the neatest finish. On a bare concrete ceiling, choose surface mounted. In wet areas, pick a fitting rated for moisture, such as an IP65 surface mounted light. Then choose the colour temperature for the mood of the room.

1. Check the ceiling. Tap or look above an access panel. A hollow plasterboard ceiling can take recessed lights; a solid concrete ceiling calls for surface mounted lights.
2. Check the existing holes. If you are replacing recessed lights, measure the cut hole and match it using the size table above.
3. Consider wet areas. For bathrooms, corridors and covered outdoor areas, our Surface Mounted Waterproof Ceiling Light is rated IP65, comes in 6500K white only, in 18W (240 mm), 24W (300 mm) and 36W (400 mm), from S$15.
4. Pick the colour. 3000K warm white feels cosy for living rooms and bedrooms, 4000K cool white is a neutral white for most rooms, and 6500K white is crisp for kitchens and work areas. Our tri-colour downlights switch between all three.
5. Plan the wiring. Reusing existing lighting points keeps the electrician's job simple; new or moved points also need new wiring.

Both ranges come with a 2-year warranty in 6500K white, 4000K cool white or 3000K warm white.
