McCulloch USA has received their first shipment from Taiwan. I got mine last night after hours from the Sales Manager.
The new production model has a much better ballast and the cold start up time (after unit was "off" for eight hours) has been significantly improved only 7 seconds!
Another minor improvement over the prototype is the focus/adjustment is easier to work, and the beam pattern is smoother when at wide angle.
They have managed to tighten up the swivel head, which was a little sloppy on the prototype.
