Great Reasons to Switch to LED Lighting #1: Ludicrously Long-Lasting
LED lighting technology has improved in leaps and bounds since its inception, and now it occupies the top spot as far as modern light sources are concerned. This series of LED Monkey blogs examines why LED is taking the lighting world by storm and gives you some great reasons to use it as your primary source of lighting.
By now, we’re all aware that LEDs are up to 90% energy-efficient. Indeed, when compared to other light sources, an LED bulb like a 6W B22 LED Bright Stik
from GE (General Electric). It generates the same number of lumens as a conventional incandescent B22 bulb, however that bulb will consume around ten times more power to achieve an equivalent level of brightness!
Unlike traditional light bulbs which can shatter and break with the slightest of movements, LED bulbs are extremely robust and durable, and this leads us on to the real reason we’re here today – their incredible longevity!
Longer Lasting Lighting
While old-school incandescent and halogen light bulbs have an expected lifespan of between 750 and 2000 hours, you can reasonably expect an LED like the one mentioned above to last between 25,000 and 50,000 hours!
You might be scratching your head right now (see picture - right) and asking yourself how this incredible feat can possibly be achieved.
Well, a major cause of bulb-demise is the heat they produce. That’s right, traditional light bulbs are the authors of their own misfortune, because they’re simply unable to get rid of the heat that they themselves produce. And they produce a LOT of heat!
In fact, up to 90% of an incandescent light bulb’s energy is wasted on the heat it produces when it passes electricity through its hair-like filament. Hair-like filaments, unsurprisingly, don’t last very long when heated until they’re white-hot, and this accounts for their short life-span.
LEDs, on the other hand, work in a completely different way and while the process does generate a very small amount of heat, this is very quickly drawn away from the bulbs all-important electronic components by an integral aluminium heat-sink that’s located at their base.
The video below contains all the proof you'll ever need that LED lights and bulbs generate less heat than incandescents!
Fewer Replacements - Lower Costs
As such, your LED light bulb won’t need to be replaced every five minutes, and unlike traditional bulbs, don’t simply go POP or fizzle out. No, after a certain amount of time, an LED will begin to emit fewer and fewer lumens levels over a prolonged period of time. Why, even long after their stated lifetime, LEDs will continue to operate for years, but at less than 100% efficiency.
This process of output reduction over time is known as the “L70 rating”, the number here referring to the period before the system begins to emit less light and operates at less than 70% of its maximum output.
So, while a traditional incandescent bulb can offer between 750 and 2,000 hours for the longer life varieties, LED bulbs afford in the region of 50,000 hours of light, which means that even if it's switched on for 8 hours every day, you won’t have to replace one for over 17 years!
