T-numbers refer to the diameter of the bulb in 1/8's of an inch. T8 is 1"
dia, T12 is 1.5" dia, T5 would be 5/8" diameter, etc. T8 is the size used
in most commercial florescent fixtures in offices and the like and is made
in huge quantities as a result, which tends to make it the cheapest size.
You probably can't beat a DIY T8 fixture for bang-for-buck, but it will be
a lot larger physically than a PCF fixture for the same light output. MH
(Metal Halide) are my personal favorite but they're also probably the
trickiest lights to set up, and they are *not* cheap, even DIY (mostly due
to the bulbs).
I think you'll be happy with the 4x55w PCF setup. You *really should* try
fertilizer and even CO2. At least do fertilization at water changes though
as a minimum if you want to have your plants stay at all healthy. Planted
tanks range from just lights and water changes (with undemanding plants) up
through fully automated CO2 and daily fertilization, but you don't have to
get all fancy and complex to have a tank you can enjoy. Start with some
basic fertilizers like TMG or Seachem's Flourish (and Flourish Iron, you
really need both). Before you know it you'll be hooked and be back here
digging into CO2 systems :-) It's really not hard, you just have to be in
the habit and be consistent.
