Well I'm definitely going to buy some T5 power compacts now as Mantis147 has shown me some great pics on how he installed them into his existing hood. They are much cheaper than the Arcadia Luminaire that I was originally looking to buy!That would probably only be sufficient for soft corals and maybe some of your hardier LPS like zoo's. Those are pretty low wattage T5s and would have a somewhat tough time punching through your water. Power Compacts (PCs) would allow you to keep more LPS and PERHAPS an SPS if it was at the top of the tank. PCs are essentially twin-tube T5s with way more wattage, 96W per bulb for 3 footers
I live in Whitley Bay, Newcastle, UK. I wonder whether I could haggle down the price with my LFS if I bought it all in bulk?Where do you live?
Got mine for £7.50/kg
