Why do AquaRay lights produce shimmer effect, while fluorescent lights don ?
Generally speaking, the larger the light-emitting area of the light source, relative to the surface area of the water, the less shimmer effect will result. Because fluorescent tubes are Omnidirectional (they emit light in all directions) and the light is emitted from a large area (the entire length of the tube), they tend to nullify any shimmer in the confined area of an aquarium. Single-point light sources, such as the AquaRay LED range deliver specific beams of light which are refracted and reflected independently by water movement within the aquarium. This is what produces the same natural shimmer that occurs, for example, when light from the sun hits the surface of the ocean.
