Most racers order one of our 20,000 lumens pit sky light sets either in 10 foot dual or 5 foot dual configuration. The 10 foot dual 20,000 lumens is the ultimate in pit lighting, and breaks down to 5 foot sections for easy storage in your truck or racing trailer. The 5 foot dual 20,000 lumens set is the same amount of light just on a shorter pole, perfect for UTV racing, side by sides or medium sized vehicles. We do offer single 10 foot 10,000 lumens and single 5 foot 10,000 lumens for half the light output. The 5 foot single 5,000 lumen is great for karting, motocross, or smaller race vehicles and still provides an amble amount of light for smaller areas.
