    Default 600w MH dimmable ballast

    Is it ok to run 600w MH light on ballast turned down to 250w as it produce to much heat running on 600w?

    I have dimmed ballast down with same bulb with fine results, but people are going to say that?s wrong and tell u to buy the right wattage bulb. I am sure they r correct, but I?ll continue dimming the same bulb. If I were u I would just get the temps under wraps, what?s the setup like?

    i'v got an early stage seedlings and I don't really want to invest any money in cfl or low wattage bulb, so was just wondering will it be ok to run like this for couple of weeks

    when you dim any bulb your outputting the wrong spectrum ''K'' and killings the bulbs lifespan,



    user preference but i don't wanna be buying bulbs every 6 months so i use the correct bulb for it's wattage setting
    your bulb/money

    That?s probably the right answer, the wrong answer again being, as they are seedlings, they don?t need much, and u would be fine... imho.... for a small amount of time. But then again I?ve been called an idiot more then once in my life:

    different opinion that's all matey, fook the idiot bit man ffs
    that's why i enjoy open forums so much tbh

    replied to a post on here not that long ago where the OP had bought a new 600w
    dimmed it down to 250w after 2-3 weeks the bulb quit and it wouldn't fire up anymore

    he ended up having to buy a new 600w bulb, they cost alot more than a 250w
    am actually trying to save him money in the long run, but again it's not my money or bulbs
