How meny for each lamp? plz help

I need to know how meny plants grow for each lamp

Buyin a system, only trying to grow bou 4-5 for now and more in the future

how meny plants go for each lamp?

150W HPS
175WHPS
250W HPS
400W hps?

if the 400w is the best since i can have up to 12 but grow 5 with good yeild i can do that, was only worrying about heat since i hear they get very hot. its going to be in a grow system(hut, tent, w.e) inside a closet.

6 to 8 plants for a 400 watt HPS. Thats just my personal opinion.
