Which 1,000W Ballast? Nextgen Lumatek or Gallaxy

Have a few options of digital ballasts to choose from.
Which would you buy and why? Price doesn't matter

all 3 are great ballast i just like my dimmable Lumatek its the shit !!!

magnetic will last forever put off the same lumens(assuming you have a new bulb) and if it does break parts and ballasts are cheaper dimming your light reduce life of light bulb. gthe only thing electronic got on the magnetic is they are slightly brighter holding a steadier herts wave

I own Lumatek.....going with Gallaxy on my next purchase though.

I own a Nextgen but I never tried those others. It's small , lightweight, cool to touch, dependable, and my electric bill only went up $20 a month.
