Right Light For 55 Gallon

I'm going to be setting up a 55 gallon aquarium (will be drawing up plans for it because I am combining two of my tanks into this one and upgrading one of my other tanks from a 10 to a 20 from the combined tanks, and I am going to be doing a sand waterfall in this). I will have this heavily planted because I have 12 bettas going into this (combining two sororities, their dither fish, and the other females I have not in sororities, as they were a little small to stick with others without causing harm). This tank will have a canister filter. I have everything from a moss tree to anubias and water wisteria going into this tank. the substrate will be a mix of black diamond blasting sand, eco-complete, and some blue gravel (to make a "river" from the water fall, need sand for that though). I will be building the stand for it as well, but I really need lights that can handle the depth of the 55 without frying the anubias or other sensitive plants.
Please help me find a good light. (I'm willing to spend up to 100 on the light alone.)
Thank you for any help.

Tlr I need a light that will go the depth of a 55 gallon (21"?) without frying plants and under 100$.

 

Check out BeamsWork 6500k lights on eBay. There are several options and "topdogsellers" is the seller to look for.

 

Finnex Stingray

 

Will either of those reach the 21" depth?

 

I have a Finnex 24/7 in my 55 gallon and it works fine. Stingray is better suited for a low light tank

 

How do these look?

How about this, what lumens, wattage, etc. would be recommended for a 21" tall tank? I am debating doubling up two types of light (in case above, a T5 and an led of "lesser power").
