How Many Lights Should I Have in My Pool?
Figuring out how many lights you need for your pool can seem tricky, but it's actually pretty straightforward once you know your pool's size. If your pool is smaller than 300 square feet, you'll only need one light. For every extra 200-300 square feet, you should add another light. So, a 15ft x 30ft pool might need 1 or 2 lights, while a 20ft x 42ft pool would do well with at least 3 lights.
But, there's more to consider than just the size of your pool to get the lighting just right. You also need to think about the shape of your pool, how powerful your lights are, how wide the light beams spread, how you arrange the lights, safety, and what you personally want from your pool lighting.
