Purchased a new ICE CAP 175 MH set-up with sider reflector last week. In the same order I purchased another spider reflector and ushio 10000k MH buld for my existing 175 MH set-up. The ICE CAP system worked great However after I changed out the reflector and mogle socket on my old system the new 175 Ushio bulb would not light. I put the old 175 reeflux bulb in and it woked just fine. Any suggestions?
