I have read that link and did you notice the red printing in the beginning?
NOTE: The information in this article is now out of date. BGH highly recommends not using this information to base your decision on when choosing a new digital ballast. The most notable change is that the Galaxy ballasts have been redesigned. They are now almost identical to the Lumatek, but they are dual-voltage (120V/240V) and work with every lamp that BGH carries.
So you are saying the published information here about this ballast is not true?
Galaxy 1000W HPS/MH 120/240V Multi-Watt & Dimmable - Galaxy - Top Brands - Ballasts - Grow Lights & Equipment - Greners.com

I read it to do what I want. That is the only one I have found that says this, otherwise they are all the same.
