Garage

The Hexeli rule is approximately 1 hexagon per 1.5 m² of ceiling, or 0.55 hexagons per m² in a garage. This works out to 11 hexagons for 20 m², 17 for 30 m², and 28 for 50 m². For ceilings over 3 m high, add 50%.

No, because the light is not concentrated at one point. It is distributed over the entire grid, which eliminates the "spotlight" effect and harsh shadows. If the garage also serves as a living room, plan for a separate circuit to light only a part of the grid in the evening.

Assembling the frame, yes: the panels screw to the ceiling and connect to each other with connectors. Allow about 1 hour 30 minutes for a standard garage, with two people. The connection to the electrical panel, however, is a job for an electrician — which is also what makes the installation insurable.

The grid adapts: we follow the shape of the room instead of forcing a rectangle. On a low ceiling, we never lower the panels, we widen the grid. Around a beam, we go around it rather than interrupting it.

A LED strip consumes significantly less than fluorescent lighting of equivalent power. The right thing to do is to compare lumens, not watts: watts no longer tell us anything about the amount of light since the switch to LEDs.

Neutral white 6,500 K for working: this light renders colors without distortion. RGB is an ambient complement, to be placed on the periphery or on a wall—never as the main lighting for a workspace.

Yes, provided you stick to the same series. Two different series will never give exactly the same shade, and on a ceiling, this will be immediately noticeable. The simplest solution is to order one more panel than you need and keep it.

It can be replaced individually, without touching the rest of the frame. This is the advantage of a modular installation compared to a single-piece luminaire.
