StarGlo fixtures are flexible and are great for lighting up rock waterfalls and landscape features. Using StarGlo fixtures (or kits) you can light areas of cascading water in the waterfall. The StarGlo fixtures should be placed above water level and pointed towards areas where the most water action will occur. This will typically be at the bottom of a waterfall with the StarGlopointed back towards the cascading water. DO NOT place the StarGlo submerged under water! It is NOT a watertight fitting!
