Well yes and no. I did order this:
http://www.htgsupply.com/viewproduct...roductID=48956 but the ballast is Digital Greenhouse the bulb is a GrowBright 600 watt HPS Bulb. Are they the same company?
The 400w bulb is a Slyvania HPS 400w bulb you can get at your local hardware store (US).
The GrowBright 600 watt HPS bulbs are the ones that keep blowing out.
