Trying to find what light I need for 75 gallon...

Hey guys so I currently have a 75 gallon aquarium with no plants in it right now. I want to find a light to try to achieve what I'm aiming for but I have no clue what to get. I don't want to get into the co2 injections and I want to avoid heavy algae blooms. I not trying to go nuts with high light plants and I want mostly low light low requirement plants-- Anubis, Java ferns, java moss, crypts, maybe some amazon swords. It's a standard 75 gallon aquarium. I know that t5hos are the best but I heard that using those without co2 will cause major algae blooms and will put me in the high light category. Another person mentioned using a dual t8 fixture but I'm not sure if that will be enough and I just can't find any dual t8 aquarium light fixtures. I can't mount the light over the tank so twists going to have to sit on top of a glass top. Second, I'm not even sure which bulbs to use or any of that good stuff since I am new to this whole aquarium thing. Any suggestions would be great, specific fixtures suggestions would be great, along with specific bulb recommendations. I am on a bit of a budget so it can't go too crazy. Pease help!!!!

Wide range of opinions on this for sure.
On a budget to me means not going big on lighting. That does not mean you can't grow plants. Keeping in mind that algae is almost a given for any new setup, I feel it just has to be managed. Low light does not make it happen. I recommend looking for a low cost fixture and add a set of bulbs of your choice to fit. I have a left over used Sears shop light over my 125 and I'm okay with that. Look for one or two light bulbs of the correct size/type to fit the fixture. Bulb output is rated in Kelvin. That is a kinda / sorta guess at the frequency of light produced. I go for 6500 K bulbs.

You can buy duel fixture shop lights at most hardware stores for pretty cheap. $20 or so each in T12 or T8 then slap some 6500k bulbs in and they should be fine to sit on a glass cover. Another option more people are using these days are the screw in CFL bulbs in 6500k and using heat lamp style metal dome fixtures.
