Doesn't necessarily matter how much it 'uses', it's how much it 'requires' 
to give an adequate output when it's enclosed inside a basically black box 
with only the bare skin of its teeth (a few mils) sticking out.

You'd be amazed at how much light you can get when some of them are driven 
at just a few mils. You don't want it BRIGHT.
