The
@Final Phase Should I just get a 600w with a "dimmable" ballast? I know 600w is more than enough light for a small area but if I can raise and lower the wattage wouldn't that be better for me long term? Would a 600w buld running at 400w produce more heat that a 400w?
The settings usually are:
100%
75%
50%
and Super Lumen if it comes with that feature.
Soooooooo, A 600 watt dimmable would go - 600, 450, 300 watts....
Sounds good for the future.
The heat output will be more doing 450watts than a 400 watt ballast..........
Not all ballasts are alike. I've felt some very cool to the touch digital ballasts and a few that are hotter. I've have two digital 400's by different brands - One is defiantly hotter than the other - that alone will heat up your space faster. Move it out of the space if possible.
I like this ballast company. I got another one from a different company that didn't work and had to send it back.
This one works like a champ. It also has a feature to look for - A fan - That little fan cools this one down better
than an older digiral that had no fan built in.
