I don't know if you guys have ever measured this before, as I just eyeball it, but I was behind a large holly bush today and I was curious. So I took out my tape measure and measured exactly how long it is from the house to the edge of an mr-16 uplight using a 60 degree 20 watt bulb. I know I adjust this as the beam narrows and the house gets taller. but overall I was curious what you guys think is the perfect distance to get the perfect wash on an 8-10 foot tall soffit using this bulb. I measured 14 inches, and I checked and I was within 1/2 inch on all the other lights just eyballing it. anyone else?
