Proper lighting for your fish and plants present in an aquarium adds to its beauty, but the type of light you need depends on what tank system you are running. Here we will discuss various types of lights available for an aquarium and the source to get them.

• Incandescent Bulbs: These bulbs are best suited for live plants but generate more heat which will cause difficulty in regulating the temperature in your tank. They consume more electricity and needs to be replaced quickly.
  
  
• Metal Halide bulbs: These are energy efficient bulbs but are expensive and generate too much ultraviolet radiations. When you choose these bulbs go for those designed for marine aquariums along with an ultraviolet filter.
  
  
• Power Compact Lighting: These are the most popular choice amongst live plants and reef enthusiasts. These bulbs are available in several varieties and provide three times more power than similar N.O bulbs.
  
  
• Full-Spectrum Fluorescent Lighting: These lightings are still considered the best and provide the best quality and quantity light at the lowest up front, operational and replacement costs.
  
  
• You can find and purchase these lightings on the Internet, at an independent pet store, or at some of the chain pet stores.
