Lumens for hps, cfl, mh are all just lumens. So for any type of light you use the more lumens the better. Lumens are lumens no matter how they are sliced, it is the color spectrum that is different.
Yes hps is a red spectrum light which is best for flowering and suitable for vegging.
Mh with blue spectrum is best for vegging and suitable for flower but not optimal.
Cfl's are great for vegging especially because of power consumption, cost, and heat, this is what i use for vegging plants.
Floros are also great for vegging, but not for flower.
Stay away from halogen!!!
