I dont think so ohgee but i could be wrong,from what ive seen the new controller actually has only a small cord that goes to connections inside of each light unlike a control box where just you plug the power cord into it and powers it up and down,the new lights are powered up all the time and the timer just turns them on and off like a switch if that makes any sense.That is also why one controller can run so many lights,the controllers actually have very little power running through them.Its like a sprinkler system,water pressure(power) is always there and the timer actually just activates the valve through a very low power cord to open and close it(power on and off).Also the 750 uses a new 750DE bulb unlike the 600's SE bulb setup.
