Ha ha! Yup, stuff the office rental. I’ll open an acid-house club instead ?... Stick to the psychedelic colours though ?

A quick question if I may.In principle it looks and sounds fine. Depending on what work is being done in there. For instance if colour is important you might want to consider higher CRI factor. It sounds like you will be doing officey things in there? If so you need to get lights which have a UGR of 19. You need to know in advance the lumens deliver to desks, assuming there will be desks from your descriptions. The one big factor you need to work out is what is the inrush current. That amount of lights will struggle not to blow the MCB due to inrush. You might need to split them up circuit wise. You do not seem to mention emergency lighting or anti panic (required in a room that size. Just a few thought for starters. By the way I do a lot of commercial LED retro fit and upgrades. Oh and I don't personally like the asymetric nature of the layout.

that looks better to me, but should be more on red circuit, less on yellow and blue. and i would opt for 10A C curve MCBs on all 3.The perception of colour is unimportant.
Most of the work which matters will be scientific research type stuff, with people and machines. A desk or two for recording research results, but mainly people milling about.
Good point about inrush. These fittings from TLC are soft start so I'm guessing a 3P B6 MCB will be fine. Each of the three circuits would be on a separate phase anyway.
A few fittings will have emergency back up batteries. I didn't mention that for clarity.
I've never heard of 'anti-panic' ... My industry mitigates that risk not by engineering contols, but by excluding the kind of people prone to panic
Good points about glare. I have bought one 5000K panel, and it looks OK - very evenly lit - unlike the point-source retina-busting nature of many LED fittings. Despite that I've now changed to spec to 4000K panels.
One guy did complain last week in another workshop about the unnatural quality of the light from my metal halides. But he was a techie physicist dude much given to speculation on the psychological effect of discontinuous spectra, so I ignored him. ?
You and Telectrix have caused me to have a rethink. Thanks! Here's a new plan:

I'm slightly concerned that this might not be bright enough. It's theoretically 610 lux with all on, but it is a high ceiling at 3m: the inverse square law is a bugger.
This new design allows for the easy addition of another 13 panels on the red circuit at the red X positions if needed.
I'd originally used so many fittings, together with the weird asymmetric arrangement, so that any one circuit on alone would not be too patchy.
Cheers, Mark.
Because no two jobs/rentals are the same I don't have the luxury of being able to install overall/task/accent lighting in fixed places. So I'm trying to go for two fixed levels (say 'normal' and 'bright') for the whole area.Are you (OP) trying to raise the lighting level for the whole area for detailed/inspection work or just specific areas?
We did a similar job couple years back where the overall/general level of lighting was high (>500lm) and just specific areas (Panels side by side) to raise level (>800lm) where detailed work was required.
Arrangement looks odd on paper but worked in practice - It was a small photographic/print works FYI.
