Eric, look back a couple of pages. I tried an MR16 replacement with 48 LEDs and was not impressed enough to continue using it. However, the LEDs did not seem to be particularly high intensity so the ones from SuperbrightLEDs might be much better. If anyone has or plans to try the ones from SuperbrightLEDs let me know. I will send this bulb for comparison. In fact if anyone wants it I will send it anyway - free to good home. The light is certainly more than the small Cateye headlights. It doesn't seem any brighter than the Cateye EL300 5-LED light, but it covers more area so I guess it does put out "more" light in total.
