THANK YOU SO MUCH!! These measurements are incredibly helpful to me, as well as many others, I'm sure!
I really appreciate you taking the time to do this! Now I just need to figure out what my light diffuser screen deducts. Lol! Long story short, I bought a diamond light diffuser (the kind that go over florescent ceiling fixtures) in an attempt to reduce the shimmer/strobing effect caused by the leds. It works amazing, and really calms things down visually, but I have no idea how it affects par values. (If anyone else hates the shimmer effect like I do, give that a try - it works great) For now I have removed it though so that I can guess at my par based on varadidguy's numbers 😃. Thanks again Varadidguy! You rock!
