HPS- Light Distance Chart
hmmm ive never seen the MH one before. i knew HPS gives greater lumen output per watt than MH but i never realised the discrepancy was so large.
i wonder if having an extra 14,000 lumens would be more beneficial than more blue light, with a 400w HPS over a 400w MH in vegging; in terms of speed anyway.
id really like to do an experiment

is it actually worth using the budget option of cfl or saving some pennies for a hps or mh light instead?

I'm with Keengrow, i use cfl's in veg and keep the lights real close to the plants, heat not being a problem. I then switch to 600W HPS's, two of them, for flowering. I've been experimenting with the distances lately and find that the sort of reflector you have, and its corresponding light pattern, is something to keep in mind as well.

If you use MH & HPS together, you're yield, quality, trichome production everything is far superior to one then the other.
Ok already posted this on another thread but then found this one. Thought it better placed in here. Hope they are accurate enough:
