LED Bulb Is Safer To Use Or Not

LED bulbs, Light emitting diode, is substitute of incandescent light bulbs and has received so much popularity among common people that every house has a special place for this. In 2009, incandescent lights were banned and in 2014, United States banned it. But even people have questioned that whether it is good or bad to use LED instead of incandescent light bulb.

Benefits of LEDs

There are few benefits of LED bulb which can be enlisted as:

  • Long-lasting

The average lifespan of white LED bulbs is almost 20 times than that of incandescent bulbs. Where the incandescent bulbs last for 750 to 2,000 hours, LED bulbs can last for 35,000 to 50,000 hours. CFL bulbs last for 8,000 to 10,000 hours. The lifespan of LED bulbs is measured in terms of its brightness and not it terms of its burning out rate. A LED bulb is considered out for use when its brightness falls below 70%.

  • Low temperature

Incandescent bulbs emit heat which causes wastage of 90% of their energy. It is 80% in case of CFL bulbs. LED bulbs emit light in a certain direction which makes them more efficient when compared with incandescent or CFL bulbs.

  • Size

LED bulbs are small in size which makes them perfect to be implemented at places that might be unsuitable for conventional light bulbs.

  • Durable

Unlike conventional light bulbs, LED bulbs are not made up of glass which makes them more durable and do not break easily.

Drawback of LEDs

Oladele Ogunseitan, Chairman at University of California-Irvine’s Department of Population Health and Disease Prevention, stated that, “LEDs are touted as the next generation of lighting. But as we try to find better products that do not deplete energy resources or contribute to global warming, we have to be vigilant toxicity hazards.”

LEDs are being popularized and now it is widely used instead of incandescent light bulb. However researchers had declared that it was completely safe to use as it doesn’t contain mercury but it contains arsenic, nickel and lead.

According to Ogunseitan, manufacturers of LED can easily switch over to safer materials which would make them safer for people as well as environment. Copper found in LEDs are harmful for aquatic animals if it is left to accumulate in lakes and rivers.

Harvard University claimed that it emits more blue wavelengths rather than conventional light bulbs.

ANSES which is the French Agency for Food, Environmental, and Occupational Health & Safety cited that “Blue light is recognized as being harmful and dangerous for the retina, as a result of cellular oxidative stress”.  It also said that light-sensitive people, children and workers are highly affected by blue light.


Final word is based on the conclusion that LED bulbs can be manufactured in a better way to avoid the resultant hazardous situation. Laws can make it better but an appropriate manufacturing process should be evolved through technology. Well, it can also be a great way to save electricity, power and cost and can never be a choice that would fall in bad decision.
