May 12, 2015 at 16:30 comment added Andrew @LDC3, Taken from the initial question: we have measured a variety of lights (LEDs) at a given distance from each light (8"). The other numbers you reference are as follows: 0.002 meters = radius of the LED :: 0.00893 sq ft = surface area of the hemispherical measuring unit :: 0.0115 meters = radius of the measuring hemisphere.
May 12, 2015 at 1:59 comment added LDC3 You measured 120 lux at what distance? 8" or 0.00893 sq feet? 0.002m or 0.0115m? I'm confused.

Better formatting, clearer explanation of requests assistance, and discussion of what has been tried.
May 12, 2015 at 1:06 comment added Andrew @DaveCoffman I am also still seeking answers to questions 2 & 3. Can you assist with those?
May 12, 2015 at 1:04 comment added Andrew @DaveCoffman, Perhaps you missed the part of my post where I mentioned the following: I have found lux to lumens calculators but am quite sure that I'm missing some very basic information on the geometry of light propogation and the best units to measure this. I'll edit my question to reflect the requirements of my question and the operable guidelines I've already been through
