Light Level Meters

I use my own type of sunshine meter!
I keep several lawn chairs out in the side lawn, near a pine tree. When the sun is shining, i set in that chair, and when the sunshine gets too hot, i move it into the shade. that is how i know if the sunshine is too hot, or too cold! If i can't see my shadow, out in the open lawn, that tells me the sun is not out,or it is after dark, or it is a cloudy day. Simple-huh? Not me--my way of testing! ;
