A light-emitting diode (LED) is a semiconductor light source. First appearing in 1962 as practical electronic components, the early version of LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Getting straight to the physics: When this form of diode is turned on, …

For more than a century, incandescent bulbs or globes have been used as a staple light source for most houses and businesses. In 2007, the swirly CFL (compact fluorescent light) energy saver bulb was introduced to the mainstream market, pushing the energy hungry Incandescent onto the ‘death watch’ list for US congress. Judged to be …

How is an LED light environmentally friendly, and who says so? There are two ways that Homie’s light bulbs help to create an environmentally-aware alternative for lighting. The first is that LED lights (Light Emitting Diodes) are focussed on using as little energy as possible while creating as much light as is needed.  Each Diode …
