Depending upon where you tank is set up, you might consider using fixtures that are suspended from the ceiling or from an overhead shelf on chains. They allow you to raise or lower them to increase access for maintenance, etc. or just to change the look of the tank. They're great if you have any emersed plants like Pothos or others growing with their roots in the water.
My lights are just ghetto-style worklights, but I have helped a buddy do the same with his lights which are fancy-shmancy high-zoot aquarium lights and it works just as well with them. We built an enclosed hood-like structure mounted permanently a couple feet above the top of his tank, and he has several different lights hanging up inside that. They are not visible when observing the tank from the front, and the last time I saw his set-up he had a wonderful jungle of Pothos and Spider spider plants flourishing in the open space.
