General-purpose 5 mm ("standard size") ultraviolet LEDs with a water-clear lens. Surprisingly bright, especially if you look at the mCd rating, because mCd is a unit of measure that takes into account human eye response, and these LEDs are on the very edge of visible light. Works very well as a "black" light to make objects fluoresce and for recharging glow-in-the-dark materials. A great bargain!

(What's that yellow thing in the photo? It's a fluorescent yellow sticky note, which lights up when hit by the UV from our LED!)
