This is completely wrong. How can they consume the same amount of power but be more efficient? You are the one spreading misinformation.
The bulb is 1000W, and consumes 1000W, the ballast also consumes power to make the conversion from 120/240 to the MH/HPS output. An electronic ballast is more efficient because it consumes less power to make this conversion than a magnetic ballast. This is why an electronic also runs cooler, there is less energy wasted as heat during the conversion.
Your electric usage and therefore bill will indeed be lower with an electronic ballast.
FWIW, I replaced all of my magnetics about 2 years ago. Would never go back. Just bought a few more - all Quantums. I run Galaxies, as well. No issues at all.

Can you elaborate more? What makes you sold on them.
Subjectively, a 600w ballast runs maybe 10-20% cooler.How much cooler are they than the same watage HID?
In terms of the heat put out by the ballast, the difference isn't night and day. The primary befit of a digital ballast is consistency. Where as a magnetic degrades over a relatively short period of time, the digital doesn't. Hell, I could have bought a half dozen digital ballast with the loss in yield from the one magnetic I cited earlier. That's not even a year.I am looking to lower my heat, but if they don't run a whole lot cooler I won't bother switching.
My Phantom ballasts say
Imax 9.2a ... so 9.2a x 120v = 1104
Lumatek says 8.42a x 120v = 1010
Does this mean my Phantoms are costing me nearly 100w more to operate?
Running 10 phantoms vs 10 lumateks is damn near like running another 1000w light when compared with the lumateks?

In regards to the dimming.. is input energy reduced when dimmed down.. or is the unit still using 1010w even when dimmed to 75% or 50%?
do you really believe they degrade that quickly??? Not wanting a pissing match but I am going to digis real soon but I never saw that kind of regression from my mags over 4+ years with the same ballast.. just curious
