This is my personal experience with solis tek. Bought 8 of the first version 1 was a dud and they replaced it. Now 4 years after 2 of the 8 have shitted out but Im in FL and we get crazy lightning so I cant blame solis cause Ive lost plenty of electronics to lightning. The problem is the newer version 2.0 that I replaced the 2 fried ones with. First off how you gonna make a new version that uses a different controller? That pissed me off. Then with our frequent power outages here the v2.0s loose the time amd come on when they please whereas the origionals keep the right time and come on when theyre supposed to and dont fuck your crop by running in the middle of your night cycle. The galaxy digital logic is the exact same as the first version and even uses the same controller. Bought 2 of those to replace the v2.0 and no problems. I find it absolutely retarded that a company would make a good product then discontinue it and then make a shitty product to replace it. And its really fucked up the new ones use a diff controller while another brand uses the same old one. I can honestly say the origionals where good ballast and recommend them but since this new version bs solis tek has lost what would have been a loyal customer
