I've done a lot of research on switching out the #44 bulbs on my Old Chicago for the less power-hungry, not as bright #47 bulbs. I just want to know how much dimmer are they and is it really worth changing to #47s. My main concern is that right now I really like the way the playfield lights up ( it's nice and bright with the #44s). If I switch to #47s do you think it will be not bright enough? Or will I barely notice the difference? I'm leaning towards the #47s, since I intend to keep this machine for a long time. What do you guys think? Thanks again for all your help!
