Aquarium Lighting, Aquarium Lights, & Metal Halide

Selecting the right lighting is essential for a successful freshwater or saltwater aquarium. Lighting is one of the most important components of a reef aquarium. Correct color with the appropriate intensity is a critical factor in the health of aquarium organisms. A combination of fluorescent actinics, 6,500-degree K, and 20,000-degree K metal halides are what many aquarium hobbyists consider the most pleasing, not only for the tank inhabitants, but also for viewing pleasures. Get familiar with the aquarium lighting spectrum so you can determine the correct lighting for your particular needs.

Q & A
Q: How often should I change my Metal Halide bulb?
A: Metal halide bulbs should be replaced after 8-10 months of use or after 3000 hours of use. Although the lamp will continue to light beyond this they will have lost up to 30 percent or more of their lumen output while consuming the same amount of electricity.
