I just started here about the time the threads died down I personally like this nano "Current Cardiff Aquarium System"
The Current Cardiff Aquarium System lets you explore your creative side whether you desire a marine or freshwater setup. Simply choose brushed aluminum 150 watt, 14000°K HQI fixture or a Italian Glass 55 watt 50/50 2C Compact Fluorescent (CF) fixture to suit your aquarium lighting needs. Each pendant light fixture is designed to reduce heat load without noisy fans and feature a fully adjustable arm for convenient custom positioning.
