etc dimmer

Hello all, I plan to wire some general house lights to D20 dimmers for my upcoming show, I know how to wire it no problem the one question I have is, is there a maximum number of bulbs I could put on on channel of a D20 dimmer, what is the max if I say was putting 120v 50watt bulbs in...

I found a Lycan Miget HP on a dimmer. Is this ok to do? It is running off an ETC Cem3 dimmer, the level for the spotlight was set from the dimmer's cpu, not the desk.
