Isn't "Watts" (or more rather "power") just current, times voltage? Or some such. So if volts are 110, or 120, or whatever it is out the wall, and one is rated X current draw, and one is Y current draw, and X > Y, then how can the two ballasts have the same wattage rating? Like for the WH7 and the WH8, they can't both be 220W, one must be more like 215W and one more like 218W.
Or am I completely out in left field here?
...
Oh, on a point of interest, I got this email from Fulham today regarding the availability of ballasts for 175W metal halide, and ballasts for 250W metal halide ("HighHorse" model line ballasts):

Tony - these are not yet available. I believe we will have an offering
sometime this summer.
Thanks!
