Step 2: Focus
Put it all together and you have one tiny little light that is getting more efficient all the time. While LEDs have been used for indicator lights for a long time, their progression into the rest of our lives continues. Many flashlights and headlamps now use LEDs to provide long hours of light. The next step is for interior lighting. While LEDs are already used for accent lighting, it is only very recently that LED bulbs that go into regular light sockets are being sold in stores.
Despite all the technology it's easy to see the appeal of LEDs and even get started with them. Take one 5mm LED and a coin cell battery and slide the battery between the two wires. You'll have light! And if you didn't, just flip the battery around. Add a magnet and some tape and you have an LED throwie to stick to some metal. For now, just enjoy the glow and think of some places it would look good.
