Umm... I'm a schmuck. I think all my flow problems are from a faulty bulb! So I found my stash of 100 watt reflector bulbs (Finally!) hidden with some Christmas decorations. I screw 2 in & wait 4 hours... Nothing's happening. Bases are hot, the globes aren't. Then I compare the old bulb R20 to the newest... NOT a true reflector! It's painted WHITE, not silver! Double DOH! I've read a few referrals here, just want the list again! I've found this, but is it a TRUE reflector? I'm heading to a local lighting store tomorrow, hoping to find a couple bulbs.
Hard to find here, too Ant. My Hubby callsed our A&S Lighting, they said that the R20's are no longer made. So I need sources or alternative light & heat sources.
