Why are LED bulbs harmful to health? Pros and cons of LED lamps that few people know about

LED bulbs are very popular. And this is understandable, they have many advantages. But there are also several important drawbacks that are not customary to talk about. One of them is harm to health. Let's talk about this in more detail.

First, about the advantages of LED lamps:

1. Profitability. LED bulbs save energy. They are about 10 times more profitable to use than conventional incandescent bulbs. And with our constantly increasing prices for light, the desire to save is paramount.

2. Manufacturers of LED lamps assure that their lamps can work for about 30 thousand hours, which is not the case with incandescent lamps. They can withstand only 1,000 hours.

3. Construction safety. LED bulbs have plastic diffusers, not glass.

Now it comes to the important - the disadvantages

The main drawback, which many do not even realize, is harm to health. LED bulbs have a negative effect on people's vision.

The main reason is the failure of manufacturers to comply with the production technology. Because of what LED lamps have violations:

- increased ripple.

- defective frequency converter.

Some lamps have a 100 Hz ripple bridge rectifier. This frequency is very harmful to the eyes, so vision starts to shrink. In addition, this frequency also affects the psychoemotional health of people.

The negative health effects of LED bulbs can be reduced by choosing the right bulbs.

What to look for when choosing LED lamps

1. Colorful temperature. It is worth buying lamps with a light close to natural. The coefficient should be in the range of 2600-3400K. This indicator reflects the radiation intensity of the LED - blue spectrum.

Vision begins to drop extremely quickly if a person spends a lot of time in rooms with an increased blue light coefficient.

In children's rooms, LED lighting should be abandoned. The retina of children's eyes is very sensitive. You need to take care of it. Therefore, give preference to halogen or incandescent lamps.

2. Flicker frequency. This indicator should NOT be in the range of 7-350 Hz. Otherwise, such lighting will negatively affect the nervous system.

According to the norms for residential premises, the pulsation coefficient of lamps is considered safe - up to 12%. It is worth sticking to it.

As a rule, only good expensive LED lamps have indicators that meet the standards and are safe for health. When buying, pay attention to the coefficients described above. And buy lamps in trusted stores.
