I'm making the switcheroo from 1,000 watt magnetic ballast blooming to using 600 watts electronic ballasts. Any specific, experience-derived recommendations out there for 600 watt bloom bulbs when using electronic ballasts?
I think sunmasters 1 of them.
Sunmaster is what I've used with magnetic ballasts. They are good, but I did get one that formed an off-axis hot spot, causing it to fail early. These were their 1,000 watt HPS bulbs.
