LEDs, or "light-emitting diodes," have come a long way since they were introduced as red, green, and blue computer indicator lights.
These days, LEDs are available in endless shapes and sizes, a wide variety of colors and neutrals, and offer many benefits over traditional incandescent lights.
For starters, LEDs can potentially cut energy usage by 25% in the U.S. How? Here's the science, made simple: incandescent bulbs convert most electricity to heat, whereas LED lights convert most of the energy into light. That's why LEDs don't give off heat the way traditional … Read more
