I absolutely love the NICREW lights found on Amazon. I've got them on almost all of my tanks now. They have some that are just a one and done light spectrum (lights, blue only, or off), but in the last few years they've started making a bunch that you can manually adjust both the white light and blue light settings on to customize to your liking for your tank. These are my preferred, and they come in all different lengths. I personally don't like a crap ton of light on my tanks either and find lights that are "for" the tanks size are way overkill, so I'll use what is advertised as like a "5/10gal" light on my 75gal, etc. My current 75gal has this one on it, in this size (the actual light is about 10" long) and it's perfect for my tastes. This is from Amazon.ca so price shown is CAD, I'm sure it's significantly less if you're in the US.
