  1. will a hps light run in a standard light socket?
     
  2. No. You will need an external ballast that matches the wattage of the bulb you want to use. I hear that the 150w set-ups are not really cost effective since you can get 400w for not much more money. I have a 400w and it works awesome. It's good for about 4 plants max though imo.
     
  3. It won't even fit, requires a mogul socket. And yes a ballast.
     
  4. thanks i did some reasearch and im just gonnna wire my own ballast
     
  5. sounds safe
     
  6. I believe that a 600W HPS gives the highest efficiency, in terms of lumens per watt.
     
  7. If you're building a cab that's 2x2 or 2x4 you should take a look at the PL-L lights I use.

    I mean, if you're going to wire a ballast, why not wire a dead simple one and get better quality light and density?

    A scrog under these is amazing. :)
