LED lights are often marketed as a way to closely mimic moonlight in a tank with nocturnal creatures. Aquarium LED lighting is also available that will replicate sunlight and light a tank well throughout the day.
Many aquarists choose LED lighting because it is energy efficient, and the bulbs can burn for thousands of hours before they require replacement. For users who plan to install one set of lights to run for a 12 hour shift throughout the day and a lunar set which will be on 12 hours overnight, the cost savings are substantial. LED aquarium lights are easy to install and bulbs can often fit existing fixtures.
For those interested in reef aquarium lighting, a metal halide aquarium light is the recommended choice. Metal halide aquarium lighting burns with a great intensity and will fulfill the higher wattage requirements for coral and anemone health.
Instead of the wide beams produced by the aforementioned lights, these bulbs emit more concentrated beams that are the closest match to natural sunlight.
Installing metal halide lighting is more labor intensive than other options, as special fixtures, ballasts and a cooling system must be added to a tank. Due to their high intensity, they will require more energy to power them, and users should be prepared for a higher utility bill after installation.
Most new aquarium lighting systems can easily be installed at home with few tools and little effort. Before purchasing a system, talk to your aquarium dealer about DIY aquarium lighting kits that can be hooked up with ease. Take a few extra minutes during the installation process to add a lighting timer that will ensure stability in the schedule of your fish.
Before choosing a new aquarium light, take the time to research the natural environment of the fish and plants that will be living in your tank. Finding the right spectrum and intensity will mean healthier fish and more robust plant growth.
