If you have some time and like to tinker you could do what I did on my first FLOWER tank and DIY an LED light solution.
I purchased a programmable LED controller like this one (

The RGB strip used 3 channels, the white another, and the two blue on the last. Once you know what you know what your LEDs will use for power you can figure out what you need for a power supply. I believe mine was 2 or 3 amps.
I was able to adjust the color of the the light as I liked it and had nice dawn / dusk dimming. I will admit the program for this unit is not that friendly but I found it manageable.
If you go this route, take your time, don't pay extra for rush shipping, and plan out as much as possible. You will need a decent soldering iron, so if you do not have one factor in $50.00 for a decent one. One other thing I will mention, be sure to use some mechanical fastener with the led strips, the adhesive will likely let go at some point, and you do not want them falling in to the tank!
