Fiberstars Lighted Rainfalls are designed to provide single rows of water and project them away from the falls lip at a 45 degree angle. The rows of water simulate the sound and effect of rain falling into the pool creating a unique and pleasant sound for you. The minimum water flow is between 5 and 8 GPM (gallons per minute). Keep in mind that as you increase the GPM flow rate, the further out the “rain” fall will extend from the wall of the pool. Our Lighted Rainfalls requires the least amount of fiber for the maximum amount of light output. Each one comes with 45’ of pre-attached fiber.
