Length Between Bulbs and Ballast

[BigDawg]

I was wondering how far you can have bulbs from your ballast. I saw that Nextgen digital ballast claims that you can run the bulbs 65ft from the ballast. Is this possible with any other digital ballast or magnetic ballast? How do you safely extend the lamp cords?
