For those of you using 1000w HPS for flowering?

My Lumatec lasted a few months before it got hot and melted the plastic inside the ballast, it still works but I don't use it, can't trust it. I also have 2 old style magnetic ballasts that I have had for over 12 years, I still use one for veg.
See if you can find the ballast you want to buy on Amazon, they usually have lots of reviews to help you decide.

Lumateks are great ballasts. I'm sorry yours didn't work out for you.

My hydroponics store says they sell 4 times as many Lumateks as other ballasts, with great customer satisfaction. I've had mine for 5 years, and it's still going strong and running cool.
