will a 400watt hps produce the same amount as light as a 600watt hps closer to the canopy?

You will not receive the same brightness from the 400W that you would get from the 600W. Moving the light closer to the plant will take a chance burning the plant. Other things like node spacing and the ability to get light to the lower plant could cause you problems. If heat or power consumption is not the problem go with the 600W. I have been growing with 1000W for several years now after going thru the testing of different wattages and light sources, i.e. CFL, fluorescent, etc. The only problem I had to take care of was the heat generated by the light. You dissipate the heat and you never have to worry about light with a 1000W HPS/MH system. See sample just harvested. 5X5 tent.

so if its too hot move it higher up and all will be fine?

so if I had to move the light up 10 inch to reduce the heat back to the same level it would still be better than a 400?

Better?
You mean a 600w 10" higher?
Get a 1000 with a dimming ballast and put it in an air cooled hood. The eternal quest of indoor growing is more light. It is hard to compete with the sun.

yeah a 600 10 inch higher than a 400 to get the same feeling of heat on the hand is it better or identical lumans

What size space are you trying to light up? What's your budget?
Those are the two biggest questions that nobody bothered to ask.
