With any new technology, there are bound to be a few public misconceptions. It may surprise you that the statements below are completely false:
All light sources generate heat, so don’t let anyone tell you that LEDs are an exception to the rule.
It is true that LEDs do not emit as much heat as other sources of light: that’s because they are so energy efficient. However, LED fixtures still need to be designed to dissipate heat; otherwise, they will fail prematurely.
Where did this common misconception stem from? LED fixtures feel cool to the touch as long as they’re designed properly. As you can see in the photo, it’s even safe for a baby to hold a lit LED!
“LEDs are available in ‘white light’.”
Technically, there’s no such thing as a ‘white LED.’ The LEDs you see that emit white light are likely actually blue LEDs with a yellow phosphorus coating, producing what appears to be white light.
Another way to produce the color is to mix red, blue, and green LEDs in close proximity. This method is used commonly for large signs, such as jumbotrons.
“LEDs are so energy efficient that it takes years for them to burn out.”
LEDs are ridiculously energy efficient, there’s no doubt about that.
However, did you know that LEDs never burn out? When they come to the end of their life (after about 17 years of regular use), they will simply become progressively dimmer.
