My experience with LEDs:
+1 on LEDs being perfectly adequate for SPS. I just wish I could figure out how Dez manages to get his iPhone to take such good pictures of his, as my iPhone has a grand mal seizure every time it looks at my tank. The sensor practically explodes when it looks at the LEDs of my radions.
If I can sort that out, I'll have a whole bucket of photos for you (photo-bucket, get it?
)
