When you need to put your floodlight up high, but do not need the extra durability, the BD-8UD and BD-8UND is perfect.  All the light power, but with an industrial construction that will not let you down.  These units are twin 500W quartz halogen lamps that will light up to 14,000 sq. ft, mounted on a telescoping tripod that brings the lights between 4 and 8 feet off the ground.  Separate 10A switches allow for independent operation of each light, and each fixture independently rotates 360° to give you the most flexibility. The infinitely adjustable steel base expands to 48" and allows the use of sandbags for added stability.
