I considered doing cfls from a hardware store but im not sure on what fittings i would require. I would prefer something that i can plug in and not have to wire to the mains! Can you help out fittings? I would use 4 20 or 25w cfls. That would be equivalent to 400w right?
It would add up to 400w incandescent but nowhere near that of a 400w HPS . Incandescent is about the most inefficient bulb out there .
Please do yourself a favor and red up on the types of lights before you buy anything . Don't just listen to one person - research and make an educated guess for you and your set up , budget , availability , and time restraints .
You could use CFL's this time around if it is all you can get and you may find it is enough for your needs . If it isn't , you can always use them for vegetating and/or supplementing another light source your next run .
This should be a good place to start -

I haven't read through it but I trust it is accurate . I started doing this before the internet but when I was starting out I would of killed for resources like this - especially for free !
