The DH 125w Economy Compact Fluorescent Fixture & bulbs.
Warm bulbs are (2700k) are best for general growth and flowering. Cool bulbs (6500k) are best for seedling, cloning and vegetative growth

You can use 400w HPS, I do but I also run AC and air cooled hoods too.

With air cooled hoods (you will spend more money) and good air flow air in and air out as well as a good fan for air movement you can run 400w HPS lights. I don't want you to think you can't use HID lights in C-13 cabinets because you can.
