Thalia 50Cm 36W LED Oyster Step Dimmable Ceiling Light

The Thalia OY50 is a 500 mm round oyster with a teak wood finish — 36 W giving 2,790 lm, with switchable 3000 K / 4000 K / 6000 K and three-step dimming from the wall switch you already have.

This is the size to buy, and the figures say so

• 300 mm — 12 W, 620 lm — 52 lm/W
• 400 mm — 24 W, 1,575 lm — 66 lm/W
• 500 mm — 36 W, 2,790 lm — 77.5 lm/W

Three times the power of the smallest for four and a half times the light. The Thalia and Lyric are the only size ranges reviewed in this programme that get meaningfully more efficient as they get bigger — against the Tifton pendants, which double their wattage for 19% more light, and the Patino, Privas and Ivalo, which give identical output at every size.

If you need output, the 500 mm is not just the brightest Thalia — it is the cheapest to run per lumen.

It dims from an ordinary wall switch

No dimmer, no new wiring. Flick the switch off and straight back on and the light steps down: 100%, 50%, 20%, then back to full.

At 2,790 lm that matters. This is a bright fitting — enough to light a living room or a large bedroom on its own — and the 20% step is what makes it usable in the evening. Getting that from the existing switch, on existing wiring, is unusual and it is the best reason to choose a Thalia over a plain oyster.

Three colour settings, reaching daylight

3000 K, 4000 K, 6000 K, set on a slide switch at installation. Most switchable fittings here stop at 4000 K; 6000 K is true daylight. Combined with the step dimming, one fitting gives a bright daylight working setting and a 20% warm evening one.

500 mm of timber, 60 mm deep

At 2.2 kg and only 60 mm from the ceiling, this is a large disc that stays flat rather than a bowl that hangs into the room. The teak wood tone is the point: at 500 mm across, a warm timber circle is a deliberate architectural gesture where a white disc of the same size is just a large white disc.

That is what the copy means by Japandi, Scandinavian and Bohemian — all three built on warm natural materials in simple geometry.

Where it works

• Living rooms and large bedrooms — as the only light.
• Retrofits — step-dim from the switch you already have.
• Japandi, Scandinavian and warm-modern interiors.
• ⚠ IP20 — not a bathroom. The Lunos squares are IP44.
• ⚠ Set the colour temperature at installation; it is fixed afterwards.
