Yeah, you would, but at 2" it would be a lot brighter than at 1 foot, and at 4" it should be half as bright as it was at 2". I think. You also have to take into account that light isn't projected in a square, either, but that is the basics.

Haha, its been like 2 years since I took AP physics.


Here it is a little more in depth if you were wondering

Light intensity: Why to keep lights as close as possible Light intenstiy = Total Light Emitted / ((4 x pi) x (radius^2)) And light intensity decreases by 1/x^2 where x is the distance. So like if you have 135,000 lumens at 1 foot, you increase that to 2 ft, you it would be 135,000 x 1/2^2 which is 1/4 so basically one fourth of 135,000 = 33,750. Add one more foot, 135,000 x 1/3^2 = 135,000 x 1/9 = 15,000. Crazy huh? Thats why the top bud always is so big and the bottom ones are smaller, cause they get a lot less light.
