so I got a few pm's about these ballasts and im just getting to them lol.one guy asked me to answer in open forum about them so here is my take.i like these ballasts because they are small and are also 600 waters.the fact they are dimmable is just a bonus,but in my op I do have spots where the plants get tight and I cant raise my lights in a few places.when my plants get to where I have pinched and bent and they still crowd the bulbs I have no problem turning my ballasts down to 400watt for a few weeks.i still get nice colas and I think it helps them not get scorched or get all foxtailed out.
I also use these @ 400 watts in a few corners where im just looking for some weak spot coverage not primary lighting.as of today I have 16 lights total and im putting 2 x 600 metal halides in 2 corners where I used to have 400hps.ill get slightly more lumens and a better spectrum in that part of my room so ima check it out for a few runs.
I also keep a spare ballast on hand in case an older one fails like just happened this week and having dimmables gives me a spare no matter which ballast fails.couple times I have had power failures from storms I run just 8 or 9 lights at 50% power off my generator(all my nextgens and
nanolux are generator ready)and it keeps my cycle going and gives me plaenty of power to also run my house,well,fridge,furnace,and veg room t5's.those are some pluses I see with these,peace:cool:
