duck!, here's a wild pitch:

How many lumens per watt does a campfire produce?

It was suggested that I start by figuring out the lumens per watt for a 
candle, because conversion from (Thee Standard) candle to lumens is 
fairly straight forward.

Of course, I can't be sure a candle consumes watts of energy the way a 
burning log does, but, you know, I just want a number--an 
interesting--if fuzzy--statistic to help compare and contrast various 
light sources.

Hints and suggestions?  Words of encouragment/discouragment?  Thank you 
very much,

Jason
