Light Emitting Diodes have been around for a long time but now more powerful LEDs have been created, light bulbs are made with these LEDs inside them. The LEDs are so powerful that they shine brightly at over 800 lumens yet they use around 10 watts of power.
LEDs use less power than incandescent bulbs and compact florescent bulbs yet produce the same light. Now even LED tube lights have been made with their own special starters.
Even LED light bulbs give off a small amount of heat so they are not 100% efficient. They don't turn all of the electricity that enters them into light, this means there is still room for improvement and I hope that in the near future a more efficient family of lighting systems are created that turn all of the electricity into light with no heat produced.
Thanks to the new advances in technology we get more light for less power. The sodium street lights are also being replaced by LED light systems and bright low powered lights are everywhere.
