Hang 'em high and watch 'em fry!

The main advantage to 315W CMH lamps is the fact that you can spread them out to get superior light distribution.

No Sir- the fact that you can spread three lamps apart to get more even coverage is the reason why it's better.

This is a big advantage of LED lighting as well; lots of light sources evenly distributed across the canopy definitely help growers get better results with them than with big single point light sources, irrespective of spectrum or efficiency differences.
