Even though LEDs have matured into a mainstream industry, with LED lights powering everything from road-lights to desk lamps, there still remain some lingering myths related to the technology. LEDs have become so ubiquitous in our modern day world that most people probably don’t even take note of the difference in the lighting they see around them. But even so, there’s no reason to let rumor and hearsay persist when simple LED testing can enlighten the public in regards to any long held beliefs about LEDs.
Search online and you’ll find the list of LED myths or safety worries to be somewhat long, and often, odd. LEDs have been rigorously used and tested for decades now, so why these concepts persist is a bit mysterious. One answer may be that in such a specialized field (lighting and energy), the novice member of the public has only a small base of knowledge to draw from.
But as with our cutting edge products that test LEDs, we can help. Below are some common LED myths as compared to reality.
Myth 1: The bulbs aren’t as bright:
- For modern LED lighting, this concept has been debunked time and time again. When LEDs were in their infancy, there was some lower quality with the light output, which may have given fuel to this myth. But LEDs in 2017 often measure directly with incandescent lighting. And consider this: we use them in the majority of stoplights.
Myth 2: LEDs produce no heat:
- This is close enough to the truth to where it may have powered the myth of heatless light. LEDs do, in fact, give off heat, just not on the level of other lighting (which can be a good thing, in many cases). LEDs do not give off infrared and ultraviolet light waves, which can allow them to run cooler.
Myth 3: They can make you go blind:
- This may stem from a recent study in Journal of Photochemistry and Photobiology in which researchers exposed retina cells to 12-continuous hours of LED light. After this, there was some damage. Of course, these were just retina cells, and if you stare at any bright light for hours on end you can damage your sight. There is no evidence of a distinct LED danger.
Myth 4: Blue LEDs are dangerous:
- Blue light, whether it comes from LEDs or any other source, is handled in a unique way by our eyes. And to be exposed to blue light directly for long periods of time can cause minor health issues. But this doesn’t really correlate to LEDs in the sense that blue LEDs are more dangerous than those that use other parts of the spectrum.
LED testing can, and has, alleviated most of the fears regarding LEDs, but a little more knowledge never hurts. Check out our OL 770-LED and Aries spectroradiometers and our Mantis imaging colorimeter to see more of our innovative designs.
