Pool lights provide safety and create a nice atmosphere at night. They will show imperfections when on, especially with certain liners. (See “liners” above). Some complain about them attracting bugs but if that happens you can turn them off.
Standard white light This is your basic pool light and gives off the brightest light.
Color changing lights They can be set to continuously change colors or display one color according to the mood you want to create. They are great to have but are more expensive and are definitely not as bright as the standard white lights.
Fiber optics Fiber optics can be used to create custom effects and can change colors or stop at one color. They are much weaker for illumination purposes than other lights and they are very expensive. Their longevity is limited.
