Ive used 600w before, though Im only wantin 1 x 1000w as Im in a 4 x 4 room. Heat aint an issue, got a cool tube and fan. I want 1000w penetration!!!
Only reason I was goin for a digital is because they dont pull as much electric, thogh if any1 can recommend a good magnetic(analog?) ballast, that will not pull more than 1.1 kw/h every hour, ie an imput of around 1100w, or less, let me know and Il be happy to go with it.
I did a quick search, found a "Maxibright" 1000w ballast, sounds good, though any1 no what it pulls in watts per hour
cheers
Dump the cool tube and buy a parabolic, you need an oversize tube for 1000w anyway can't use the 600w version the bulbs are a lot bigger it shocked me when I first saw it.
The parabolic and decent ventilation and I guarantee you won't see heat problems.
Lights on 23C ish lights off 15C (I know I need a heater) using 300m3 fans for intake and outake which are both split equally using T pieces into 2 tents.
The ballast is too hot to touch but keep it clear and good airflow and everythings fine.
In all honesty the ballast is cooler than my old 600w's but I got them from a skip.
I don't know if you've ever used a digi but my lumatek 600w still bangs out a shit load of heat less sure but they're still hot I bet the 1000w's get pretty damn hot.
Reliability well magnetic ballast been round 20 years+ digi 5 years, I'd put my bets on the magnetic.
