If you look at Big Al's web site under T5 bulbs you will find that NO is only 28 watts for 48" bulbs and HO is 54 watts for 48" bulbs. Just using Big Al's as a reference not recommending them! Coralife T5 fixtures are also NO not HO. Maybe it's just Coralife that has NO bulbs and fixtures? Home Depot also has a few fixtures on their web site. A 39" fixture (36" bulb) is only 21 watts compared to 39 watts for an HO fixture.
