I have been considering upgrading my lights on my NanoCube 12 DX from the stock pair of 28 watt PCs to four 28 watt PCs. If I do this I will be buying the kit from www.nanocustoms.com but I would like to hear someone opinion of the upgrade that has done so themselves. Is the upgrade a worthwhile investment? Should I consider going a different route? I plan to keep bright colored zoos mainly and want the best lighting to really make their colors stand out. TIA, Skip
