  1. Hey guys I came across a pretty nice hydro store while out of town and purchased a 400 watt light system that can change between mh and hps. He threw in the hps with the deal but I'm afraid something may be wrong with it.. I fired it up and it seems to work fine, only thing is that theres a strange rattling from inside ether bulb.. this can't be good right?
     
  2. could be your fan vibrating the lighting?
     
  3. No, if I hold it in my hand and lightly shake it without it being screwed in it sound just like a regular light bulb that's burned out
     
  4. prolly the arc tubes support rods dinging the glass, some of mine do that i know.
     
  5. yep. no problem. if they vibrate while on, might cause premature failure id think? also remember to wipe off your bulbs when you bare hand them. iso alcohol and water.
     
  6. I sure hope so, ill just call up dude tomorrow and see what he has to say, thank yall for the quick responses
