To get more watts from an LED fixture you add LED's so based on that and the fact radion is modular............
I am not seeing good feedback as yet on the XM units out there, the intensity is too much so I will put my hat in my mouth and say it would not surprise me if we see the XM not really taking off, so that leaves us back with the ever popular XPG. Manufacturers do try and match an LED to an MH fixture, I am not sure this stands ground with all fixtures due to PAR and spectrum variations. Based on my own experience this is what i advise, and this is generic not related to any fixture --- up to 120w without optics I advise a tank depth keeping SPS of 24" IF optics are applied this is stretched to 30+" Ai is 75w with optics and very good (although spotty) at 24" above that it struggles from experience tank dimension is different LxW as this is fixture design specific. Based on this I would happily say that the Radion at 24" will easily compete with a 400w MH. Cot analysis - Long term the LED will pay for itself if you ook at the cost of 400w MH bulbs, most tanks have two? A decent bulb will cost you around $60-$70 twice a year, In one year your can save yourself $280, and thats before taking electricity into account.
