Hi I have emailed shane from migro to see if he could setup 3 aray maybe for me as the 4 aray is 98cm long so won't fit but then I've seen the silver brackets that hold the led so maybe removing them and the lights will be closer together less gap between hmmm.If you buy that lamp you should be able to dimm it down to 163W or even less. So heat won't be an issue and your efficiency will be super high. If you want you can get the TS2000 (or Migro Aray 4) and dimm it down as well.
