Perfecto Manufacturing APF26483 Marineland Fluorescent Perfect-a-Strip Deluxe Light Reflector for Aquarium, 48-Inch, Oak
Now, how do you begin to quantify all these effects? Here is some intuition: With a proper reflector, the light can be assumed to be focused in one direction, straight down into the tank. Not completely true, but close enough. The effects of the water are negligible, any healthy aquarium is clean and clear, and not very deep, 2-3 feet to the bottom. That's not enough water to matter much, and many of the plants are quite tall and reach almost up to the surface. I will also mount the light as close as possible to the tank, so that will be a minor issue as well.

Reflectors for Aquarium Lighting
Cichlid-Forum • Reflective / diffuser film for aquarium lighting
ith the help of my colleague David Flanigan, an organic chemistry professor and fellow reef aquarist, I tested the effectiveness of some reflectors used with T-5 fluorescent bulbs in aquarium lighting fixtures. We knew that any sort of reflector in a fixture would help send more light downward into a tank, but we wanted to see some hard data, and wanted to compare a couple of different types of reflectors in the process. So, we set up a test tank, got a light meter and a couple of fixtures, and got to work.Internal Lamp Reflectors are used to direct a portion of a 360° lamp output to increase the magnitude of the output in one direction. The reflector effectively re-directs the light from the sides and back of the fluorescent tube to the non-reflector area of the lamp coating. Many applications use this technology in conjunction with an external fixture (polished or metallic) which also acts as a reflector to direct the light energy to where it is needed the most. Common applications for this technology ares the flexo graphic, aquarium, scanning, vision markets and essentially, anywhere light distribution needs to be optimally distributed.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.A reflector is best when 100% of the light that strikes it is reflected, and none is absorbed or transmitted through the reflector. If you want to reflect an accurate image of a very dim subject you also want the reflection to be accurate, which is why telescope mirrors use highly polished glass, for the accuracy, and a very uniform coating of aluminum, for the near 100% reflection. But, for our aquariums, we don't care if the reflection is acccurate or not. We just want all of the light from the bulb to be reflected towards the water.
