Gday, I’m currently researching a future 5 foot, 100G Discus tank. Although its not going to be a planted tank, I would still like to grow some healthy swords and other moderate light plants thus was intending to run pressurised CO2.

Looking at the various lighting options available, I had all but locked in some T5 kits by AH Supplies (http://www.ahsupply.com/36-55w.htm) and figured 4x55W with individual reflectors would tick the boxes of my lighting requirements above. In fact a couple of days ago, I was about to post, asking for opinions of these kits when I saw a great lighting article posted by aquafrogstuff (http://www.americanaquariumproducts...._Lighting.html) which gave high output CFL’s a big rap.

I’ve since been talking to a few hydroponic stores and was looking at a pair of 85W 6400K CFL's with individual reflectors as an alternative. Each sold as a kit for around $70 each. I’m looking for other peoples experiences and recommendations of CFL’s, ie is that enough wattage, longevity of the bulbs, different reflectors etc. Also appreciate comments on the T5 option above as I haven’t decided which way to go yet.

Thanks
