Also which combination of bulbs would be best for a 55g planted tank? (the ballast is 2x54w T5HO)
Check their website. In all my years dealing with flo's I've never seen it, but there's always a first. Just gotta match the bulb wattage to the fixture (ballast). Some newer ballasts have a range rather than a specific wattage.
, I prefer to stay in the sweet spot for plants which is 65 - 6700K, but many here say up to 10,000K is fine.
