sorry guys I have been busy on a few trade shows.
Footprint: that is not an easy answer. The effective spread depends on the number of fixtures you use and the height you have available. As a single fixture you can cover aprox. 3x5' (without wall effect!) but used in conjunction the extra light outside this spread is put to use to create uniformity of light and will of course add to the overall average intensity.
3-4 foot apart in line is generally the best positioning.
Nice setup you have there. If I look at your walls the lamp can go a little bit lower still. For veg this is sufficient at 18 hours, depending on your style of grow.

I really want to try one of these. Even Better if I can convert to bare bulb vertical. They look great. I wanted to put 1 1000w in the center and my original 600w super lumens Lumateks on the ends so 600,1000,600....
Yes they do look great! Hopefully by the time I get done with my current experiment they will have their enclosed hood on the market......
Thanks, Whazzup. I had assumed from your earlier posts that when the air-cooled hoods came out, this fixture would be included. Now I feel better about having jumped into the 315w equipment!
DE bulbs are not designed to run vertical. It would be a cluster fuk if you tried to make one..
very true. I have seen the first 315 fixtures in Europe with the standard (!) CDM light retail for € 750 (that's $900!). That is a lot of money for a metal halide 315 lamp. True, it is more energy efficient than any other metal halide, but imagine replacing 0ne 1000W HPS with this lamp: $2700 for the CDM versus $590 for the 1000W HPS. You can burn a lot of electricity for $2100 
Now you could argue that the same goes for the plasma (retails at about $1250). However, the plasma does have UVA and UVB in the spectrum, a better CRI and a longer life and most of all, not much IR in the radiation at all, where the CDM is a very hot lamp.
There is something else you need to take into account. If you use the 315 for additional lighting you need a very wide hood. One 315 is more than enough for supplemental lighting of one or even two 1000W HPS. But how are you going to hang these fixtures to create the same spread?
Every lamp has its place in the market, T5, induction, PL, LED alike. It is just that you need to be careful to select the right lamp for the right purpose.

btw, just a heads up: the blackening in the arc tube is caused by us firing the lamp up for a few seconds in the final quality and safety check every fixture undergoes. This causes chemicals to temporary deposit near the burners. It is not a sign of old lamps, running them for about an hour will make the arc tube clear. Actually for photography we always burn them for an hour to make them clear. So you are not getting old lamps

does this ballast run CMH? thanks
We have no CMH lamp available for this ballast or reflector (K12-30S fitting) nor are we planning one. We don't think MH is a good option as for the spectrum, spectrum maintenance and lamp life (6-8 months), and the good CMH are only available in medium watt models and mostly low frequency models. We recommend though a combination of plasma and HPS during flowering.
Also the Plasma is only a 4x4 spread.

On the 1000w Pro fixture, is it possible to orient the ballast straight in line with the reflector, or is it permanently fixed in that L shape?
I ask because I have limited vertical space inside my tents and turning the ballast 90 degrees would save me what looks like about 8-10 inches.

When the prices come down 50% and you show independent testing that these are so much better then basic systems, let me know.
