LED stands for Light Emitting Diode, which are 'solid-state lighting' components. Each individual LED consists of a semi-conductor diode that emits light when a voltage is applied to it. LED bulbs contain no mercury and produce virtually no light in the Ultraviolet (UV) or Infrared (IR) spectrums. They can even be recycled since they contain no hazardous substances and are manufactured without hazardous substances.

LEDs consume significantly less energy and operate at lower temperatures than typical incandescent bulbs. Most of the energy emitted from an incandescent bulb is converted into heat instead of light, which is why you'll burn yourself if you try to touch it once it's turned on. In many cases you can actually feel the temperature difference just by being near the light. LEDs, however, don't burn out like a conventional lamp, so while they do produce some level of waste heat, individual diodes do not need to be replaced and they do not cause colour fading in clothes and art. The small amount of waste heat produced within the LED during the conversion of electricity into light is drawn into the downlight profile to dissipate into the air and prolong the life of the LED diodes for a safer, healthier and more energy efficient light source.
