I'm trying out CMH

You should consider the Nanolux 315W NA. The ballast can be removed and placed outside of the tent to reduce heat.

I'm in Canada, they only ship to US. Also, I have limited room and need a horizontal positioned light. Thank you though

Vivosun sells the extension plugs so you can detach ballasts and relocate them outside the tent as well. I think they are around $20 each or something like that.

I own 3 CMH 315 watt fixtures now and two are from Amazonia. I like the ones I got online better because they have the daisy chain feature, also you can easily unplug and unscrew the ballast for relocation outside the tent. You just need the extension I referred to in my post above. In my opinion there is very little difference between brands other than features. It's not like LED where you have to really shop hard to get the best light for the money. Just don't cheap out on the bulb. The bulb is what matters. I just got a Philips 3100K to go with my new light yesterday and eventually I will switch the other two bulbs over to Philips once they need to be replaced.
I now have all 3 of my fixtures daisy chained together. Works great.

It hasn't been touched on here yet, so here goes. I have 2 400watt magnetic ballasted MH. Im not using them , buddy gave them to me. Can i jam a 315 bulb in them??

bulb should be matched to the ballast to avoid fire and death.
