I'm using one Marine Blue and one Marine White. I also now have a 4x54w T-5 but if you like, I could turn off the T-5s and shoot you a photo. Would that help? You're also welcome to come by for a visit.
Personally, just judging from looks alone, I don't think these two are able to make up for MH. Well, anything over a 150 anyway. Otherwise I wouldn't be pairing mine with a T-5 fixture! However, on my 90, I'm thinking it's possible that a set of 4 strips could stand alone. You'd really want to check the PAR I think.
