The Stellar CTC is a 500mm layered circular close-to-ceiling light in white integrated 48W giving 3,280lm, with3000K / 4000K / 5000K and TRIAC dimming, projecting68mm.

Our sources disagree about what it is made of, and we wouldrather tell you than pick one.

That is a real difference, not a technicality. An acrylic fitting issmooth, slightly glossy and needs no maintenance. A fabric one ismatt and textured, warmer in a bedroom and on a ceiling itcollects dust and wants an occasional vacuum. They also look nothing alike close up.

We have asked Telbix. If the finish matters to you, ask us before you order and wewill confirm which it is.

Layered circles and what that buys over a plain disc

The Stellar is built from overlapping circular planes at slightly different depthsrather than a single flat face. Two things follow:

• It casts shadow on itself. The layers producesoft edges and depth even when the fitting is off, so it reads as asculptural object on the ceiling rather than a lit panel. That is what the copy meansby visual interest, and it is the whole reason to choose it over a plain oyster.
• The light leaves at more than one plane, so the transition from lit fitting toceiling is graded rather than a hard ring which is what makes a brightclose-mounted fitting comfortable to sit under.

3,280 lumens, and it dims properly

48W at 68lm/W enough to be theonly light in a living room or a large bedroom. It sits between the two otherclose-to-ceiling fittings in this catalogue:

All three record almost exactly the same efficacy 68 to 69lm/W which tells you they are built on the same LED platform. So the choicebetween them is size, form and finish, not light quality. The Stellar is thebrightest of the two 500mm options, giving19% more light than the Arema on the same footprint.

TRIAC dimming, on an ordinary wall dimmer, across the fullrange. At 3,280 lumens that is not a luxury it is what lets one fitting be a workinglight at full and an evening one low. Note the contrast with the Thalia and Lyricoysters, which give three fixed steps from the existing switch andneed no dimmer at all: better for a retrofit, less control.

Three colour temperatures, set at installation

3000K warm for living rooms and bedrooms right in most homes.4000K neutral for a kitchen or study. 5000K cool, whichbelongs in a garage or workshop.

Decide before the electrician leaves. Our recordflags the Stellar as colour changing, which overstates it the setting is madeat the fitting, at installation, and cannot be changed from a switch, an app or aremote. On a 500mm fitting in the middle of a ceiling, changing it later means taking itdown.

68mm deep, 4.9kg

Genuinely low-profile for a 500mm fitting, and the layered form is whatcarries visual depth at that thinness.

4.9 kilograms sits flat against the ceiling. Aclose-to-ceiling mount puts the whole weight on the plate and the ceiling surface,with none of the relief a suspension gives. On plasterboard that needs aproper fixing tell your electrician the figure before the ceiling is opened.The canopy is 395mm on a 500mm face, so on areplacement it covers most of what came off.

ClassI earth required, andIP20 indoor and dry locations only, so not a bathroom. Askus about the IP44 Lunos squares if you need one that can.CRI above 80.

Where it works

• Living rooms and large bedrooms 3,280lm on its own, dimmed to taste.
• Rooms where a plain disc would be dull the layered form has presence.
• Low ceilings and hallways 68mm.
• 4.9kg flat against the ceiling a proper fixing.
• Ask us whether the finish is acrylic or fabric before ordering.

Questions

Is it acrylic or fabric?

Our sources disagree, and we would rather tell you than pick one: the datasheet says acrylic, while our record and the old page both say fabric. That is a real difference acrylic is smooth, slightly glossy and needs no maintenance, while fabric is matt and textured, warmer in a bedroom, and collects dust on a ceiling. We have asked Telbix; ask us before ordering if the finish matters.

How is it different from the Arema?

Same 500mm footprint, 19% more light 3,280 lumens against 2,750 and a layered circular form rather than a plain face. All three close-to-ceiling fittings here record almost the same efficacy, so they are built on one LED platform: the choice is size, form and finish, not light quality.

Will it light a room on its own?

Yes 3,280 lumens covers a living room or a large bedroom, and the TRIAC dimming lets the same fitting be a working light at full and an evening one low.

What does the layered design actually do?

Two things. It casts shadow on itself, so it has depth even when off and reads as a sculptural object rather than a lit panel. And the light leaves at more than one plane, so the transition from fitting to ceiling is graded rather than a hard ring which is what makes a bright close-mounted fitting comfortable to sit under.

How heavy is it?

4.9kg, sitting flat against the ceiling which puts the whole weight on the mounting plate and the ceiling surface, with none of the relief a suspension gives. On plasterboard that needs a proper fixing; tell your electrician before the ceiling is opened.

Can I change the colour temperature later?

No. Our record flags it as colour changing, which overstates it the setting is made at the fitting during installation, and on a 500mm fitting in the middle of a ceiling, changing it later means taking it down.

Can it go in a bathroom?

No IP20, indoor and dry locations only. Ask us about the IP44 Lunos squares if you need one that can.
