I'd rather use the best bulb for plants that I possibly can (So what do you personally think is better?), as I know T8's are not as bright at the more suitable T5 lights that I would need.
Would this type of bulb be superior to the LG's for my plants?
(Sorry If you've already mentioned this. I only had a quick chance to read it this morning before I started work, so I'll be sure to come back and give it all a good read, maybe quote you on some more once I have finished work.
- Thanks once again.
Oh - There are also other Bulbs I could chose from, I've only had a quick look though.

T8 and T5 are quite different, and they need their own fixtures (the tubes are not interchangeable). T5 is available usually in HO (high output) which is roughly 1.5 times more intense than T8 in the same size and spectrum. While this may not seem like much, it is. Remembering the balanced issue, it is crucial to not have more light than all nutrients--including CO2. I tried a dual-tube T5 HO with 4-foot tubes over my 90g 4-foot tank and it was way too bright. I moved it to my 5-foot 115g thinking the additional tank length might help, but no; after a full week of using it, I took it back for a T8. The light intensity is simply too strong for my setup. If you use CO2 diffusion, this can work.
There is a NO (normal output) in T5, though this is not available everywhere (I can't get it in Canada). It is basically the same intensity as T8 in the same size/type. But T5 is more expensive, both for fixtures and tubes. This may change over time, especially as LED is now "the thing."
When we are dealing with dual-tube tanks, you have a bit more freedom. I have dual 4-foot T8 tubes over my 4-foot 70g and 90g and 5-foot 115g tanks. I have used a combo of one LG and one GE, one LG and one Phillips, and two Sylvania tubes, and plants grew fine no matter which. But here the intensity is not going to vary all that much.

Both are around the same price, although I'm not too bothered about spending a little more money on lighting if it will give me a better chance at maintaining healthy looking plants and a better environment for my fish.
Basically, I don't mind spending money on things that will help me achieve a planted tank.
With the exception of Co2.
I just want to get off to the best start that I possibly can. And everyone's help is very much appreciated <3.
And as for T5/T8. I knew they were different, I just always presumed that T5’s were superior to T8’s. Hah.
I just really wanted to get off to a good start, as I tried to do a planted tank previously, earlier on when I didn't know all too much about Aquariums on a whole, and it left a bad vibe for me concerning plants, to say the very least.
