Lightbulbs

I read an article this morning on how LEDs are gaining in popularity.  One of the things that struck me is that they said most older homes have about 20 lightbulbs in their house, with newer houses having closer to 40.  Our 140 sq ft trailer has 20 bulbs.  I am a huge fan of light.  Especially as I get older and my eyes want to be lazy, I need light.  I can't read in the shadows, I can't tell details in poor light, nothing is good without light.  So if we extrapolate out my need for light, with a 1400 sq ft house, I'll need 200 bulbs.  Hmmm.....  Thank goodness I don't need as much light everywhere.  I can usually do without one in our pantry (though I use the one at our pantry door now quite a bit).  And I'm fortunate enough to still do fairly well in sunlight.  Just things to keep in mind as we plan out our next house.
