1 shows a white-light LED in action). It is possible to generate light in semiconductor materials (such as GaN or AlInGaP) by injecting electrons into the conduction band of the material and ...

Just like smart light bulbs, LED strip lights are savvy investments ... 32 feet of lighting or cut down to size without ruining the circuit. This kit is great for pretty much any situation ...

The LED, or light-emitting diode ... That means inside every LED bulb are tiny circuit components — and their soldered contact points — which are far more vulnerable than the diode itself.
