hello,new one here.a friend gave me a old, really old grow light ,a Prometheus brand.there is no markings on the bulb other than 2 letters(i don't remember them) and a real small square.the bulb is 8"-9" inches long and i can't bring my middle finger to thumb around it.it is frosted white amd looks heavy duty inside.the threads are standard size. i have 2 "kids" growing now and doing ok.,just ok.this grow light is like a big shop light with a huge bell reflector and NO ballast. i rewired it when i got it.just hard wired. i turned the light off the other day and when i went to plug it back in the light didn't light up.oh no.but after it cooled off it started again and i haven't turned it off since.i am in the grow cycle.and can't spell. my main question is what does ballast do and are they always needed?could i be using a hps or a mh without ballest? anyway this sight is great. thanks,todd God Bless America
Why don't you consider sourcing a replacement ballast and bulb now rather than waiting for either of the components to fail. If either of the components fail during your grow your crop and months of effort could all go to waste.
