Lighting reco for deep tank
So I'm fairly new to planted tanks, and have a non-standard shaped tank, so had a basic question. What lighting fixture would you recommend for a tank that is basically 36"x18"x24" (~65 gallons). It's tall (24") for it's gallon-size so I'm not sure how to adjust the lighting to compensate. Also, I am aware of the 3 watts per gallon rule often used, but that would need me to have the equivalent of 8 fluorescent bulbs (commonly 25 watts a piece for 36" bulbs)? It seems a little strange that I'd need a light fixture twice as big as anything I've found on the market designed for freshwater tanks.
Also, how on earth do I compare LEDs in all of this (clearly no wattage rule here). For the size of tank would I need the equivalent of a Marinelife single bright, double bright or plant specific system?
In case you're looking for further info, I was considering doing a mixed flourite/gravel substrate, weekly supplement dosing, and definitely NOT CO2. I'm prepared to limit my plants to hardier, lower light varieties to accommodate other things, like my wallet.
Essentially I would like to get more involved in plants, preferably without spending more on a lighting system than the rest of my tank/livestock combined.
