Believe it or not, there are some valid reasons behind why you would not want to buy pool lights. Now, as you are here today, we can only assume that you are interested. In spite of this, though, you still may want to be aware of some of the reasons why you could avoid buying them.
For starters, if you are never going to swim in low-light conditions (or at night), then they may not be worth it. Clearly, during the day, you will not need the lighting. Some people will also try to scare off unwanted pests and critters. But, if you do not have those types of problems, then you will not need to worry about it.
