The Altez OY50 is a 500 mm low-profile LED oyster in white — 48 W giving 3,450 lm, with 3000 K / 4000 K / 5000 K and dimming, at only 70 mm deep and 1.8 kg.
It weighs 1.8 kilograms, and that is genuinely unusual. Compare the 500 mm ceiling fittings in this catalogue:
| Fitting | Size | Output | Weight |
|---|---|---|---|
| ALTEZ OY50 | 500 mm | 3,450 lm | 1.8 kg |
| Stellar CTC | 500 mm | 3,280 lm | 4.9 kg |
| Arema CTC | 500 mm | 2,750 lm | 4 kg |
| Thalia / Lyric OY50 | 500 mm | 2,790 lm | 2.2 / 2.7 kg |
It is the brightest of them and the lightest — a little more light than the Stellar for a third of the weight. On a ceiling that matters: 1.8 kg sitting flat against plasterboard needs no special fixing provision, where the 4 to 5 kg fittings do.
That makes the Altez the straightforward answer for a retrofit, an older or lightly built ceiling, or anywhere you would rather not open anything up.
72 lm/W — efficient, and enough to be the only light in a living room, a large bedroom or a kitchen. At 70 mm it sits close enough to the ceiling to read as a flush disc rather than a bowl, which is what keeps a room feeling tall.
The white finish is the right call here: on a 500 mm disc, white disappears into a white ceiling when the light is off, so the fitting is only present when it is doing something.
3000 K warm for living rooms and bedrooms — right in most homes. 4000 K neutral for a kitchen, laundry or study. 5000 K cool for a garage or workshop.
⚠ Decide before the electrician leaves. Our record flags the Altez as colour changing, which overstates it — the setting is made at the fitting, at installation, and cannot be changed from a switch, an app or a remote afterwards. On a 500 mm oyster in the middle of a ceiling, changing it later means taking it down.
If you want colour you can change afterwards, ask us about the Corsa, whose three settings are switched from an ordinary wall switch.
It also dims, which on a 3,450-lumen fitting is what lets it be a working light at full and an evening one low. The datasheet records TRIAC, so an ordinary wall dimmer — tell us your dimmer and we will confirm compatibility before you buy one.
The description's claim of “even, glare-free light” is doing real work and is worth unpacking. A 48 W LED array behind a diffusing panel spreads the output across the whole 500 mm face, so there is no bright spot to look at — which is what makes a ceiling fitting comfortable to sit under.
The trade is that a diffuser absorbs: 72 lm/W is good for a decorative fitting and modest against a bare LED panel. You are paying a little efficiency for a lot of comfort, and on a fitting that lights a room you sit in, that is the right trade.
⚠ Two notes on our own data.

Integrated 48 W LED giving 3,450 lm, included, with 3000 K / 4000 K / 5000 K set at installation, CRI >80, and TRIAC dimming. 240 V, Class I — earth required, IP20 — indoor and dry locations only. Warranty is three years, as a replacement warranty.

It is the brightest of them and the lightest — 3,450 lumens at 1.8 kg, against the Stellar’s 3,280 at 4.9 kg and the Arema’s 2,750 at 4. A little more light for a third of the weight. On a ceiling that matters: 1.8 kg needs no special fixing provision where the heavier ones do.
It is the straightforward answer for one — light enough for an older or lightly built ceiling, only 70 mm deep, and bright enough to be the room’s only light.
Yes — 3,450 lumens covers a living room, a large bedroom or a kitchen, and the dimming lets it be a working light at full and an evening one low.
No. Our record flags it as colour changing, which overstates it — the setting is made at the fitting during installation, and on a 500 mm oyster in the middle of a ceiling, changing it later means taking it down. If you want colour you can change afterwards, ask us about the Corsa, whose settings switch from an ordinary wall switch.
It should not be. This product is an Altez; Fulcrum is a different range. If you have been looking for a Fulcrum oyster on the strength of that line, this is the fitting you were reading about.
The datasheet records TRIAC, so an ordinary wall dimmer. Tell us which one you have and we will confirm compatibility before you buy.
No — IP20, indoor and dry locations only. The Lunos squares are IP44 if you need one that can.
