We use LED (Light Emitting Diode) lighting because it is the way of the future. The technology in this type of lighting means you will be changing your light bulbs less and saving more on your power bills.
LED lighting is far superior to incandescent or CFL lights for many reasons. Firstly, they are much more energy-efficient. Sure, the upfront cost of an LED is more than incandescent or CFL, but the running cost will soon offset that initial price difference. It essentially pays for itself in energy savings.
The light to heat ratio is more effective. Where a traditional light bulb produces 90% heat and 10% light, LEDs produce 80% light and 20% heat — all the while using significantly less energy to do so.
They are better for the environment. Using LEDs will reduce your CO₂ emissions by more than half compared with a standard incandescent bulb. Furthermore, because of the long lifespan of LEDs, less waste will be going into landfill as a result of needing fewer.
Now you know why you should be using LED’s; but why recessed? Well, recessed lights look good. They are cleanly tucked away into the ceiling and therefore give your ceiling a crisp, polished look.
