These are becoming popular in replacement lamps for incandescent globes, but now you can get them separately for experimentation. They use a ceramic substrate with multiple LED chips connected in parallel, all covered in a phosphor. Note that because they are ceramic based, they are not flexible!
These are rated at 3 volts at 100mA total, 0.3W continuous. Colour temperature is 6500-7000k. Total length is 38mm, with a 29mm long light emitting area. Around 1.6mm diameter.
Use them to make your own custom lamps, or even novel digital displays (like a big numitron, just LED!)
The anode is the lead with the small hole in it.
