Light Emitting Diodes (LEDs) have been in common use for over half a century, mainly in electronic equipment, where they’re used as signals and indicators (standby lights, for example). It is only in recent years that LED light bulbs have been widely available. They are an energy efficient, longer lasting replacement for incandescent light bulbs. They emit the same brightness as traditional bulbs, using only a fraction of the power.
LED bulbs consume 90% less energy than traditional light bulbs. They also last 10-20 times longer. Over the lifetime of a typical LED light bulb, households could save a significant amount of money from reduced energy bills. Unlike energy saving CFLs, LED light bulbs can also be recycled.
Typically, LED lights have an average rated light of anywhere from 15,000-20,000 hours, compared to just 1,000 for traditional bulbs. Airius LED Lights however have a lifespan of up to 100,000 hours or more.
Lumens (lm) are a measure of the amount of visible light that a lamp emits. It is used to determine the brightness of a bulb (unlike a bulb’s wattage, which has no direct relation to its brightness).
Colour temperature refers to the type of white light that a bulb emits. ‘Warm’ white bulbs emit a softer, yellower light, while ‘cool’ white bulbs give off a bluer, more intense light. Colour temperature is measured in Kelvins (K), and typically ranges from 2000K-6500K. The lower the Kelvins, the warmer the light that a bulb emits. Typically, a warm white bulb for the home would be one with a colour temperature between 2700K-3000K, while a cool white bulb would be anywhere above 4000K. ‘Daylight’ bulbs are the coolest available, with a colour temperature around 6500K-7000K, and mimic the type of light the sun gives off during the day.
LED lights are green technology as they require a small amount of electricity compared to traditional lights to give out the same amount of light. LED lights also do not use the harmful chemicals that their CFL counterparts use.
