Need help on lighting system

[cceyz]

Hi, Folks,
I am a layman on Aqua lighting and keen to learn.
I have a brief idea on WPG and Lumeng.


But when coming to the terms T5, PL etc. and 6000K, 8000K etc, I am totally lost.How many types of aquatic lighting tubes are out there and what are they? How different are they?

What are the big names of the major brands of lighting fixtures and tubes?

I currently have a Eheim MP tank(150L, roughtly 40G) with MP lighting 2x39W T5 tubes. Don't know whether it's a good setup. I consider it low lighting since it's 2WPG, what do you guys think?

Can you guys link me to a good tutorial on aqua lighting?
Thanks in advance!

The compact fluorescent lights in the link provided by jacian refers to PL lights.
