    Hey. Gonna make this short. I have a 250W electric ballast that say it only takes mh bulbs. I knw this my sound like a stupid question, but theres no such thing as a stupid question, can I use a HPS bulb with this reflector or strictly MH?

    if its only for Mh then its only for Mh. not all ballasts are switchable.
