These pictures are taken 90 seconds apart of the exact same room. Look at how these high pressure sodiums warm up. At least on my Galaxy Grow Amps. I don't ever overdrive or underdrive, they are 1000w bulbs and the ballasts are set at 1000w always. Its
crazy how the spectrum starts off blue, I think it always did that from what I noticed.
But why one shuts off after warming up is cause for concern! They both turn on, start warming up, turn blue then yellow, then get really really bright! And presto, the one on the right always shuts off. Every morning for the last 4 months or so... lol
it glows faintly then returns to nothing, all the while the amp is happily humming away. After a few minutes it relights and then delights. I dunno... haven't switched cords around or anything to trouble shoot yet. Freaks me out when I'm in there waking the girls up trying to get photos in that narrow window.
These bulbs/ballasts combo sure squeals! Like the highest pitched upper eschelon of human hearing, wire scratching across glass, when your ears ring type of noise. It's incredibly uncomfortable. Mostly when warming up but also throughout the day its still there
