I mainly light my tank by using either direct or diffused sunlight because it varies with the seasons. I also use some supplemental light with this bulb which is run when I feel like running it.
My tank is a 45 gallon column style.

Don't worry about spectrum of the bulbs. Your tank is getting plenty of correct spectral distribution from the sunlight. What you need to do is limit the amount of direct sunlight if algae develops.

Plant heavily from the start so the vascular plants can out compete algae.
Limit fish population. Don't over stock
You don't absolutely need PO4 reducing filter media, Purgien for getting the Nitrate level in check. Plants and bacteria through metabolic activity rid the tank of those chemical elements.
Frequent water changes.
