I get lower bounce with light meter readings when I compare the KT1/2 with the KT4, same MN bulb, the KT4 showing lower lux numbers because of its deep set reflector. Actually what you are really losing is spill, the huge center spot still comes through. I also notice lower bounce lux readings using a Malkoff M61 in the MD2, with its smaller bezel opening, compared to a SF P6 size bezel opening, both using glass windows.
