Lumatek is definitely the only ballasts I will use now. I own two currently, a 600W and 400W. Both are switchable 120V ballasts.
Compared to the first ballast I ever bought, 400W Digital Greenhouse from HTGSUPPLY.com the lumateks are far superior.
The lumateks run much cooler and are completely silent not to mention their customer support and loyalty of their customers.
Also, as long as you get a good quality bulb to begin with you won't have any problems.
