The Dragon series is our most popular outdoor LED screens. The DRGO10S (10mm) is a great resolution for monument signs or for any outdoor application that isn’t high off the ground . The DRGO16S (16 mm) is perfect for LED screens high off the ground on a pole and also for billboards. You will not be able to tell the difference between the 10mm or 16mm after a certain distance except for the fact that the 16 mm is much brighter and it costs less. For this series, we use aluminum cabinets because they are lighter than steel cabinets and they don’t rust.
