We run a pretty big show. Carvin TRX speakers. Four 18's, 4 15's and Two 4" Horns per side. Each speaker weighs almost 200 pds each. Can barely lift them. I believe any size light would be secure.
I need washes. Looking also at the Martin SmartMac. Just doesn't seem to be an affordable wash (moving head) out there other than your accuwash. They will sit probably between 7 and 8 feet off the ground. Really don't want to spend more than $750.00 per light.
