to increase the focal length of the lens, you can add a -0.50 ~ -1.00 raw eyeglasses lens on the projection lens.

could you explain that in detail perhaps with a drawing or something
I rember you told me to move the lamp up and add a lens but im not sure where exactly to add the lens, i looked at the lens online
and im interested in trying one if it will make things brighter thanks
