The Secret Life of LEDs -- A new Tim Hunkins Video

Thanks to Tony G4WIF for alerting us to this really nice video from the fellow who made all those great "Secret Life of Machines" videos.   This video on LED's makes me want to improve the lighting in my work shop.  And I think I need some more high wattage resistors.   I'm really glad Tim Hunkins is making more videos.  His look at the Secret Life of  Radio was a real masterpiece.
