I played around with some new style and old style lenses on the bench, and some COB LEDs. And I mean it when I say "lens". They really do have a focal length, and you can find it when playing around with a point-ish light source. I found a distance where the COB LED actually filled out the GM lenses and made them look pretty good. The results encouraged me enough to put it on my "to do" list for the coach. It hasn't made its way to the top of the list yet, but it's still something I plan on doing someday. I planned on mounting the COB LEDs onto an aluminum plate and getting them mounted the right distance behind the lenses.
