It'd be 1.5m,2.2m,2.0m and I was planning on using 4 gn telos 0008s which are 240w each.
If you are trying to push your plants and get the best bang for your buck; for that size space, i'd definitely be looking at considerably more light. GN's site says this about the fixtures;
|PF (380-780nm)||459.8 μmol/s|
|VISUAL (WORKING LIGHT)||Colour temperature: 3002 kelvin|
|Colour rendering index: 86 CRI|
|Luminous flux: 25,145lm|
