    Mh conversion bulb same as mh bulb?

    My 400 watt lighting system uses an hps bulb at the moment. The manual says it can use a mh conversion bulb. When I look online not all mh bulbs say conversion. Does it have to say conversion or will any 400 watt mh bulb work? Provided of course that its has the right base. Ty

Ive just found out that 400 MH color temp only shows 4000 on the kelvin scale, but lumens are 36,000. 23w CFL...
