"I do have both, hps is designed hor...mh is designed vert., but I changed that, now can be used for hor. or vert."

This is all new to me but I thought the bulb was either vert or hor? Just changing the ballast couldn't change the fact that the bulb only worked for vert or hor?

And latewood I apologize in a prior post I called you lakewood. Sorry.
