question about lighting

  1. i recently bought a 400 watt digital ballast with a socket hookup. i tried to use a bulb i had bought from lowes that was a 400 watt hps bulb made for S51 ballast. does anyone know if a digital ballast needs a special bulb for it.
     
  2. you use standard hid bulbs for digi ballasts. i'm not sure, but i don't think lowes carries what you need. also, not all digital ballasts run mh and hps. i had one that was for metal halide only. you should get your bulb from a hort. supplier or e-bay. never use a bulb you're not sure of.
     
  3. ah ok thank you. well i just happened to see HPS bulbs at lowes so i figured i would try it. The brand is from Slyvania(sp?) and it says 400 watt HPS.
     
  4. Is it a MH ballast or HPS ballast? It matters.
     
  5. it is a 400 watt hps digital ballast.
     
  6. Then you should have no problem using a 400w HPS bulb working off that 400w HPS ballast.
