850mm x 850mmWhat are the dimensions on this?
cost was around £140 posted which I don’t thinks too bad. I quite like the spacing tbh. I’ve read that spacing the middles further apart reduces the hotspot in the centre plus better spread around the edges. Hopefully the profile heatsinks do their job.If you wanted to get those center strips spaced evenly like the others you could flip that angle bracket to the inside of the light on the other side of that rail to get away from those other angle brackets.
tbh mate if I was to do it again I would use 2020 instead of 3030 just to keep weight down. I’ll put a little list together for you later , just got To work.Do you have specifications of the parts you bought.
What you builded looks almost the same as what I had in mind!
I wanted to use 4040
