Description
A square surface-mounted panel reads as more integrated than a round one in modern, geometric interiors. The 43×43 cm size suits medium and large rooms.
4000 lumens covers a living room of 18–25 m². The square form gives a calmer result where furniture layout and ceiling lines are already at right angles.
Choosing a pattern
Plain and ribbed versions give a restrained look; crystal and layered versions leave a texture on the ceiling even when off. Black and coloured frames create contrast against a white ceiling and turn the fixture into a deliberate design element.
How far it stands off the ceiling
Surface fixtures typically stand 5 to 7 cm off the ceiling face. That is the trade for needing no plenum above, unlike a recessed panel. In flats with a concrete slab and no suspended ceiling, a recessed fixture is not possible at all; there, those few centimetres are not a flaw but the natural consequence of the only realistic solution.
Colour temperature cannot be changed later
In this range the colour temperature is tied to the LED board and is fixed at the time of order. Mixing colours within one space is not advisable: a 4000K and a 6500K panel side by side on the ceiling leave the difference as a visible boundary. Choose every fixture in a room in a single colour.

Usage & Warnings
Before installation
- Switch off the circuit at the fuse box before wiring. Turning off the wall switch is not enough.
- The fixture connects directly to 220–240V mains. If your installation has no earth conductor, consult a qualified electrician.
- On plasterboard ceilings do not screw straight into the board; use hollow-wall (toggle or spring) anchors.
Use and care
- Wipe the surface with a dry, soft cloth. Abrasive sponges, bleach and alcohol-based cleaners permanently dull the diffuser.
- Cut the power and let the fixture cool before cleaning.
- For indoor use only. Do not install outdoors or anywhere exposed to direct moisture.
LED and driver
- The LED board is soldered in place and cannot be replaced individually like a bulb.
- This range is not dimmable. Wiring it to a dimmer circuit damages the driver and causes flicker.
- If the light flickers or fails, the part that normally needs replacing is the driver, not the LEDs.
Frequently Asked Questions
Should I choose square or round?
It is a question of appearance; the lighting performance is the same. A square form sits more comfortably in modern interiors with right-angled furniture and ceiling lines. In classical rooms with softer lines a round fixture looks more balanced.
What room size does 43×43 cm suit?
4000 lumens covers a living room of 18–25 m². For smaller rooms take the 33×33 cm model; for larger ones the 50×50 cm model or two fixtures.
Does a black frame make the room darker?
No. The frame colour does not affect light output; the diffuser surface is unchanged. A black frame only makes the fixture more visible on the ceiling when it is switched off.
How far does it stand out from the ceiling?
Surface-mounted fixtures typically project 5–7 cm from the ceiling face. That is the trade-off for not needing a cavity, unlike a recessed panel.
Can the colour temperature be changed later?
No. In this range the colour temperature is fixed to the LED board and chosen at the point of order. Mixing colour temperatures in one space is not recommended, as the mismatch is visible.
