The Arema CTC is a 500mm low-profile close-to-ceiling light in white integrated 40W giving 2,750lm, with3000K / 4000K / 5000K and TRIAC dimming, projectingonly 50mm.

It dims properly, and that is the reason to choose it.TRIAC, on an ordinary wall dimmer, across the full range not the three fixedsteps the Thalia and Lyric oysters give.

At 2,750 lumens that matters. This fitting is bright enough to be theonly light in a living room, and continuous dimming is what lets the same fitting bea working light at full and an evening one at 20%, with everything in between. Theoysters need no dimmer at all, which is better for a retrofit; the Arema needs one,and gives you every level in return.

50mm deep, on a 500mm face

Genuinely low-profile. Most ceiling fittings of this size project 60 to120mm; the Arema sits 50mm off the ceiling, so it reads as aflush disc rather than an object hanging below the plane.

That is what close to ceiling is for and it matters in ahallway, a room with a low ceiling, or above a door swing, where every centimetre ofhead height is real. At 4kg it is alsolighter than the 700mm Astana’s 6.2, though still a weight thatsits flat against the ceiling with none of the relief a suspension gives tell your electrician the figure before the ceiling is opened.

2,750 lumens what it covers

Enough for a living room, a large bedroom or a hallway run on its own. At68.75lm/W it is efficient for a decorative ceiling fitting and worth noting, exactly the same efficacy as the 700mm Astana, whichtells you the two are built on the same LED platform in very different bodies. So thechoice between them is size and material, not light quality:

• Arema acrylic, 500mm, 50mm deep. Clean,architectural, nothing to maintain.
• Astana fabric rim, 700mm, 115mm deep. Softerand warmer, and it needs occasional dusting.

Three colour temperatures, set at installation

3000K warm for living rooms and bedrooms.4000K neutral for a kitchen, laundry or study.5000K cool for a garage or workshop.

Decide before the electrician leaves. Our recordflags the Arema as colour changing, which overstates it the setting is madeat the fitting, at installation, not from a switch, an app or a remote. If you arefitting several through a house, set them all the same: a hallway at4000K opening onto a living room at 3000 is obvious every time you walk through it.

The acrylic diffuser is what makes a 40W LED array readas an even, seamless disc rather than a panel with visible dots and it is whyyou can look up at it without discomfort. The canopy is 388mm on a500mm face, so on a replacement it will cover most of what cameoff the ceiling. ClassI earth required,IP20 indoor and dry locations only, so not a bathroom.

Where it works

• Living rooms and bedrooms bright enough alone, and it dims all the way.
• Low ceilings, hallways and above door swings only 50mm deep.
• Kitchens, at 4000K.
• 4kg flat against the ceiling a proper fixing.
• IP20 not a bathroom. Ask us about the IP44 Lunos squares.

Questions

How is it different from a Thalia or Lyric oyster?

The dimming. The Arema is TRIAC dimmable across the full range on an ordinary wall dimmer; the oysters give three fixed steps 100%, 50%, 20% from the switch you already have. The oysters are better for a retrofit with no dimmer; the Arema gives you every level in between.

How low-profile is it really?

50mm, where most ceiling fittings this size project 60 to 120. It reads as a flush disc rather than an object hanging below the ceiling plane, which matters in a hallway, a low-ceilinged room or above a door swing.

Will it light a room on its own?

Yes 2,750 lumens covers a living room, a large bedroom or a hallway run.

How does it compare to the Astana?

They share the same LED platform identical efficacy at 68.75lm/W so the choice is size and material, not light quality. The Arema is 500mm acrylic, clean and architectural, with nothing to maintain. The Astana is 700mm with a fabric rim, softer and warmer, and needs occasional dusting.

How heavy is it?

4kg lighter than the Astanas 6.2, but still a weight sitting flat against the ceiling with none of the relief a suspension gives. Tell your electrician the figure 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. If you are fitting several through a house, set them all the same: a hallway at 4000K opening onto a living room at 3000 is obvious every time you walk through it.

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.
