Thanks. My criteria for noticeably warm and uncomfortably
warm (for an LED) was about <5degF and <20degF
respectively. I know you can get more, heat, but that always
seemed to not be the thing to do with LED's.

The specs don't seem to balance.. the 4cd doesn't come
at 20ma. It's like 4cd/5degF at 180ma, 5cd/20degF_at_250ma,
0.5cd/+0degF_at_20ma. So, less light, or more current?
