Is there a difference? I have 2 4foot 2 light T-8 32 watt shop lights. From what I understand the T-4 is a bigger bulb and thats it. If the T-4s are better I will get some. I am going to order a HPS b4 I get to flowering and mh when I save some cash. Thanks in advance!!

T8's can be more efficient, as I recall.

T-8 in what I have read will not do you all that much compared to t-5s Can you swing some money towards the t-5 ?

T8s will work good...

T5s (there is no T4 that i'm aware of) are just smaller so you can fit more light into the same size space... which makes them more intense.

T5s are more expensive than the T8s, both fixtures and bulbs.

I found http://www.bulbs.com/eSpec.aspx?ID=14708&Ref=T-5+Linear&RefId=49&Ref2=Fluorescent+Bulbs these wonder if he could use those if so I might get those as well. Thing is do these need a ballast?

I found one thats called a grow one but the one above has the same specifics as the other. http://www.plantlightinghydroponics...000k-t5-ho-fluorescent-lamp-2pack-p-2163.html
