Evil Mad Scientist Laboratories gets up close to some LEDs, and takes a peek beyond the light:

I took some close-up pictures of LEDs to get a look at what’s inside. These are just standard T-1 3/4 (5 mm) package superbright LEDs with clear lenses, one of the most common types, and I took the photos by placing my the lens of my camera (Canon S3 IS) right up to them.
