me looking for it also but i remember a shop at pris( opposite sentosa marine) selling the 9watt one blue one white pc doubt its true actinic....
bro 1ft cube i dun think 2 9watts suffricient i remember that 13 watt pl is sightly shorter then 1ft....i think diy 3 13 watt is the best but finding the actinic blubs is the PITA
aniwaes check out the lights their using on their nano1footer in www.nano-reef.com seems like 3x24/32 wat pc is popular but the 70 watt MH is the most preferred
gd luck in lighting ur nano
