Automated color in a compact package- You can now enjoy the dramatic color lighting effects of SAm in your spa. Spectrum AquaLight (SAL) produces the same revolutionary 7-color spectrum as our SAm light, but it comes in a compact package. Especially designed for spas, SAL provides breathtaking color at the flip of a switch - just like SAm. SAL easily synchronizes with SAm and PG 2000 FreedomSync models to provide a uniform display of ever-changing aquatic color.
