Spectralight UV SL-500 Product Details

Less Chemicals = Healthier Pool

It's no suprise that less chemicals is better for you and your family's health. With a SpectraLight UltraViolet (UV) Pool Light, eliminate chlorine by-products and lower chlorine levels by harnessing the power of ultraviolet light - allowing you to have a safe, healthy, and easier to manage pool.

Reduce Chemicals by 90%

SpectraLight's triple-action approach disrupts the harmful loop of pool chemicals. The UV pool systems dismantle over 99.5% of potential pathogens that could infiltrate your swimming pool. The pivotal work is accomplished by SpectraLight UV, significantly reducing the need for chemicals by as much as 90%. This process ensures the removal of hazardous chloramines and other by-products of disinfection, guaranteeing a safe elimination.

World Health Organization

Professional Pool Operators of America

Davis Country Health Department

How Ultraviolet Light works in a Swimming Pool

Based on a forward-thinking blueprint for the pool and spa industry, SpectraLight emerged. Drawing inspiration from the treatment methods used in municipal drinking water systems, the science underpinning SpectraLight Ultraviolet was developed. This involves the utilization of a potent UV-C germicidal light ray, characterized by its high intensity, to pinpoint the DNA and RNA of various microorganisms such as bacteria, viruses, algae, parasites, and cysts.

Simple Setup

In approximately half an hour, you can have SpectraLight set up effortlessly through a three-step installation process. By seamlessly linking SpectraLight UV sterilizers between your current pool filter and the water line that feeds back into the pool, integration is a breeze. This compatibility extends to all types of swimming pools, encompassing even salt water pools.
