Here is it lit up with a large incandescent bulb, I think a 327w 4000 lumen multiple lamp. I later tried a regular 300w 1000 hour bulb and it was a bit brighter.
@everyone, yep it turns out the 327w 4000 lumen bulb is quite bright! I had it lit in the day and it was easy to perceive it was dim. It is actualy as bright as a freshly relamped 100w mercury lamp! Yep I plan to try lighting it in mercury too!
