    I would think for growing phals you would do just fine with a flourescent set up - which is much cheaper to operate... considering electricity costs. (I'm a bit sensitive, my last electric bill was $265)

    For phals, I think you only need 2 48" fluourecent lights if you have a window near your plants, 4 48" lights if you don't.

    HPS/HID is probably overkill for Phals.
    They do generate a lot of heat as well(good in my case as i do not have to heat my growroom).
    Flouro's are probably a better bet & easier on the eye.

    I have 2 24"in fluourecent lights (20Watts each) by Agrosun with 975 intial lumens (each bulb), color rendering is 93 (100 is sunlight), color temperature is 5850Kelvin per bulb. I have been told that doesn't do anything for my Phals...!!!

    Basically, a waste of money. I bought this at a Hydro store close to my home. The guy assure me it would be good for my Phals, other people don't agree. So I wonder if I should add lights bulbs to it (like the fixture (fluorescent) with clamps you can attached to anything, I believe is 175W) or buy a new system. I've had my fluo lights since last week. I paid $68 for the fixture and the 2 bulbs, $16 for the stand in boxstore.

    Don't be too sure of that! I think that you would be better off with Hi-Output fluoros, but they need special fixtures (T5 bulbs). So adding a couple of compact fluoros may help, but geez - you've only had then a couple weeks. Give em a chance. Do they get any natural light at all?

    Yes, you can use those compact fluourecent bulb, $9 each for 42W, the store you bought your stand sells those bulbs and clamp fixtures, they also sells 48" 2 light fixtures which is about $8 each, and about $3 for a 48" 40W fluourecent light. I just think the tube ones are nicer, the CLF bulb is affecting my eyes and the clamp fixtures look ugly.

    I think the 24" tube (975 lumens each) is those regular t12 tube, not the high output ones. My 48" tube is 3200 lumens for T12 and 2700 lumens for T8 and are cheaper than the 24" bulbs. My shelf is 36" wide and I couldn't fit those 48" fixture in the lower shelf, so I cut the fixture into 36" wide and bought 36" T8 tubes which are twice as much as those 48" tubes. The T5 bulbs are quite expensive though, about $15 each from mail order, and the fixture for those tube is even more expensive, in the $200 - $300 range. I think T12 or T8 bulbs are an ecomonic way to go.

    The $8 shop light fixture is not listed in their online catalog, and its availability is dependent on the local store. The first one in your post might be good for you, but the reflector is too wide for my shelf, and they are heavier than the $8 one (which is for both T12 and T8), so I think the cheap one better. The only differences are the $20 one has wider reflector and has a on/off switch, the $8 one needs to disconnect from the plug if you want to turn it off. Other than that, the $20 one is good for you.
