The Crystal is a self inflating balloon, which diffuses a unique light over a 360º area. The Crystal incorporates a continuous fan built inside, which keeps the balloon inflated with air and it is fitted with a powerful halogen or HMI lamp protected in a cage in the center of the balloon. Available in 3 different sizes, the light output is very bright and uniform, has minimal glare and lights up an area from 13,000 to 26,000 square feet! The Crystal is robust, simple to use and is an incredibly efficient light for many different applications, such as concerts, festivals, exhibitions, show rooms, or for receptions in hotels, restaurants, and around swimming pools... Colored covers can also be fitted to the balloons along with vinyl graphics that make the Crystal an ideal tool for marketing and promotional applications.
