A while back there was considerable discussion about using MR-16 lamps in large-scale pathlights and arealights. I recall some thoughts and opinions on this, but did not see any stories of completed projects where others tried and succeeded. One issue is the heat created by conventional MR-16 lamps within a small airspace under the fixture top. I would like to hear from the lighting veterans on the forum what fixtures they have used with this change of lamp, and the results. Thanks!
