I have a 600 watt dimmable ballest and was wondering if i turn it to the lower settings does that effect the heat given off from the bulb because i grow in my closet and wanted to grow during the summer but its to hot at 100% for anything above 70° outside

Yes if you dim the ballast you will put off less heat but honestly venting that light (if you have not done so already) will give you way more cooling then dimming your ballast. I am in Arizona and have similar problems in the summer. Good luck!

my dimable lights seem to run cooler wide open
seems the process of reducing is making more heat then open up all the way
go figure

I used to have the same problem with heat in the summer so I gave up. Now I start veg the 1st week of September and end my 3rd crop right now. Beats the heat, and everyone needs some time off. Peace

Very interesting I run 600w Phantoms and have a very noticable 2-3 degree drop in my canopy temps when dimmed to 60% what ballasts do you run?
