Bought a Solux 50W 4700K 10 Degree MR16 lamp the other day while browsing a lighting fixture shop. Spend couple hours modding a M*g 4D to run this lamp. Using the same kind of heat resistant switch mod like before ( easy to make /ubbthreads/images/graemlins/smile.gif), and 4 3AA to D holders from waion. Running with 12 Energizer 2100mAH NiMH cells, the light output is very amazing. Bright and white /ubbthreads/images/graemlins/cool.gif!!! However, there are some quite noticeable artifacts in the beam and the hot spot is not quite as smooth compare with an OSRAM 35W 10 Degree. I would say I like the beam quality better for the OSRAM but prefer the white 4700K color /ubbthreads/images/graemlins/tongue.gif
