Gym

1 hexagon per 22 sq ft (0.50 per m²) as a baseline. That's less than a garage because a gym is an open volume, but you need to add 50% above 10 ft (3 m) ceiling height — which is the case in most commercial units.

No, that's the classic mistake. It's where you most need to see: back position, foot placement, the plates. Keep full density and offset the grid away from overhead movements.

White for training, color for atmosphere. An all-RGB gym gets tiring and distorts depth perception after a few weeks. The combination that lasts: white grid over the training floor, color around the edges or on a wall.

Above anything that goes up: about 8.5 ft (2.60 m) for a standing overhead press, 8.9 ft (2.70 m) for a snatch. Over those zones, offset the grid rather than lowering the panels — moving a hexagon 3 ft (1 m) barely changes the light level.

That's a gym's real enemy. Every bar dropped on the floor travels through the structure. Use fixings suited to the substrate — not universal anchors — and schedule a check at one month, then at six months.

Light the wall that serves as the backdrop. A ceiling grid alone leaves the background dark and faces harshly contrasted. It's the detail that separates a video you post from one you delete.

Dry or barely damp cloth, power off. Chalk and dust build up on the diffusers and cut brightness faster than you'd think. Once a year is enough.

That's different equipment: you need a suitable ingress protection rating. Never install panels intended for the training floor in those areas.
