Perfecto Manufacturing APF26483 Marineland Fluorescent Perfect-a-Strip Deluxe Light Reflector for Aquarium, 48-Inch, Oak
The AquaticLife T5 HO model is a saltwater aquarium light fixture that uses reflectors to direct the light into the aquarium for maximum illumination. The fixture uses digital controls that operate independently to create custom lighting in the tank. Additionally, it has a timer to control when the lights go on and off. Internal exhaust fans and a splashguard protect the bulbs and increase their lifespan. The single cord powering the entire fixture reduces clutter. This particular model links up with up to three other fixtures to create a four- or six-lamp aquarium light fixture.
So for best light intensity, the ideal is a column of light striking the water surface perfectly perpendicular to the surface. For this comparison, we'll just assume that all the light is reaching the aquarium, or that the reflectors for each type of light are equally efficient. Keep in mind that this may do LED a disservice, because the light from LEDs is emitted pointed more or less towards the water and requires much less reflection to actually get there.

Twin-tube Compact Fluorescent lamps are a great way to pack a lot of light in a relatively small space. But if they aren’t used with a good reflector, you won’t get most of that light into your aquarium.All of this is achieved without making the reflector too large to comfortably fit over the aquarium. A H Supply’s CFL reflectors are only 2” tall and 4” wide at the widest point, with lengths to fit the various wattage bulbs. And their five facet design with only a 1” wide top surface even allows them to be used to retrofit common single-tube aquarium strip lights that have a slanted front.A H Supply’s reflector is unusually tall so the lamp can be positioned far enough up in the reflector that little side-light can escape without being redirected downward at a steep angle, and at the same time not positioned so close to the top of the reflector that there isn’t room to redirect the up-light out of the reflector and into your aquarium.While some aquarists might leave the back of their tank alone, or may cover it with a sheet of colored plastic, it's common practice to tape up the sides and top of a new tank and spray paint the back of it blue or black. However, one of the accidental discoveries we made was that this can significantly reduce the amount of light that is reflected into a tank.
