Light emitting diodes to the tech savvy, typically these bulbs are high tech while being very strong durable and with an extraordinary lifespan. White LEDs quickly matched and overtook the efficiency of standard incandescent lighting system by some distance, while standard bulbs work at around 16% efficiency, measured by its light output per unit power input, LEDs work at around 90%. Typical lifetimes are 25,000 to 100,000 hours, this is either 11 years of non-stop operation, or 22 years of 50% operation. The long operational life of a led is a vast contrast to the standard life span of an incandescent bulb, which is around 5000 hours. This means less changes and more value for your money.
A brilliant example of how LED bulbs can make a fire look realistic is the Apex Rio and Rio Grande which use unique LED technology for low energy consumption using only 15 watts which is less than a average light bulb!
