I've got a line on some classic Emulators. I love these lights and would like to add them to my arsenal... 1st off, they come with the LED controller, not the LCD controller. Anyone know if if will be a huge difference? I know it is for the Ibeam controllers, but its been so long since I used an emulator, I just don't remember. 2nd, one of them, within a minute of running, the beam goes stagnant. It could just be a galvo issue, but I'd hate to buy them and realize that I need a new board, which would essentially mean I have a parts unit. Anyone have any idea on this?
