This mini 3V blue LED light bulb is a perfect complement to any electrical science project or demonstration. This blue LED bulb will make your electrical science project light up and stand out among the competition at the science fair. Great for projects involving basic electricity circuits, battery holders, solar cells, motors, buzzers, and much more! Each bulb will last about 20,000 hours, and the vibrant color will appeal to young aspiring scientists.
NOTE: When screwing the bulb into a socket, be sure to grip the bulb by the colored rim base - if you grip it by the LED itself, the LED may break off from the base.
