Powermoon now offers its patented balloon light systems. Units are glare-free and portable. They open and close with a reliable steel spring "umbrella" mechanism (not with air pressure or gas), so they won't accidently deflate. Several versions are available with various outputs; different mounting devices such as tripods, truck hitch poles and mover carts are available. Four units can be used to light an area the size of a football field. Ten units easily fit on a pick-up truck.
