Rock Lumateks here, but look into the Hydrofarm Phantom. I have 1 of them and its nice!
12 - Lumatek 600w 240v only units and never had a problem. Wouldn't trade them for anything.
4 - Lumatek 1000w Dimmable 120/240v - so far so good.
Sealed and silent are the only options I'd consider. Eff Fans!
I say Lumatek is a sure win if you run at 240v. I think most problems with them are when ran at 120v...especially when placed in hot rooms.
I don't think this is entirely true friend. I have a lot of wireless devices & never does my Ballast interfere with them let alone my neighbors.Some good info, thanks, but I'm wondering whether electronic ballasts are safe to use now, re: electromagnetic disturbance to neighbour's satellite/radio, etc?
Thanks
Peace
I cant wait for the supplementsive had to return a galaxy before. one out of 4 was constantly flickering.
quantums are really good... and Advanced Nutrients makes ballasts now. called bad ass ballast. EVERYONE check them out. they have a 7 year warrentee. which is twice as much as all these other companies.
