In terms of a bulb, there are three options currently available to you of incandescent halogen, LED pool light, above ground pool light, in-ground pool lights, and fiber pool light. Naturally, all of them will work in terms of lighting up your pool, and the best choice for you might come down to a few areas including budget.
A halogen pool light is the cheapest by far but has major drawbacks. If you’re looking for a bulb for your home then the majority of people’s first choice is going to be halogen as it’s cheap, bright enough, produces a white light and if they are in your home then they are easy to replace.
Taking that into a pool situation though and those last three features lose their appeal when you’re outdoors. Halogen lights aren’t as bright as LED lights can be, LED and fiber optic lights can produce a vast range of colors and they both last for a lot longer which is important as lights in a pool are much more difficult to replace than in the home
As we’ve said, LED is the clear all-around winner. If you don’t have the budget though, then you can opt for halogen. If you’re richer and want the ease of use for fiber optics as well as the great mood lighting, then that could be your number one choice.
In terms of options, you can elect to either have a permanently installed solution or opt for something more temporary like ball lights. With a permanent solution, this will require expert installation which naturally adds a lot to the cost. If you have a permanent in-ground pool, then this may be the best choice. If you have a temporary overground then having an option such as the magnetic lights we reviewed her could be the ideal choice.
