Fixture Recommendation for 47 Column Tank

[fjord]

I recently acquired a Marlineland 47 Column Tank. The dimensions are 20" w. x 18" d. x 31" h. I was fascinated with the the smaller footprint and the height, and want it for a planted tank. My previous tanks, even though somewhat tall, still had plant over growing the height. So, I'm having a hard time finding a 20" long fixture for the tank that will produce enough light for the depth. Current-USA has the 6 bulb T5HO which is designed for reef tanks, and a bulb change may adapt it well. Other than that most options are for a 24" fixture, which I'd prefer to not use. Can anyone please make a suggestion for an appropriate light fixture for this tank?

Happy New Year!

Maybe a single MH lamp around 100 Watt would do.

I use two Marineland Planted Aquarium LED fixtures on my 20" cube tank. I posted PAR numbers for the fixtures in the lighting section of the forum. Odyssey Aquarium Lighting also has a 4 bulb T5 fixture that is 20". The reviews on the Odyssey fixtures are mixed and the bulb options are limited. The fixture is very affordable though.
