Thanks!

I put a chunk of 3/16 glass between the bulb and the sensor to see how much glass reduced the light and it went from 426.4 to 421.3

so abosulty clean glas reduced the light 1.2% but that number would increase very fast as the glass gets dirty. if you find you are getting salt spray on it I would recomend cleaning it every second day if you have critters that depend on the light.
