There are many benefits that a fish keeper gets by using LED lights for the aquarium. One of the first things that people love and notice about using LED lights is that they are cost-effective. The LED light fixtures don’t usually cost more than the traditional fluorescent lighting fixture, but the savings are significantly more, the electric consumption is minimal by comparison. Another benefit is that the “bulbs” last much longer than other systems used for aquarium lighting. Typically you can expect to get 30,000 to 50,000 hours out of the LED fixtures, which is another cost savings users see.
