The Reasons why LEDs are so bright for your eyes

You have finally decided to replace incandescent bulbs with LED bulbs. You turn on the LED bulb but it is too bright for you. I am sure you are wondering how but the LEDs are brighter even both these bulbs have same wattage equivalency.
Perception by the human eye
Visible spectrum is the light that can be seen with the human eye. This visible spectrum is measured in wavelengths and ranges from 380 to 760 nanometers. Ultra violet and infra-red lights appear on either sides of this visible spectrum. Incandescent bulbs have a different spectrum than LED light bulbs.
When a light source is on, most of its energy is burned off as heat which is nothing but infrared light. Since incandescent bulbs use most of the energy and this energy is burned off, the light in the bulbs become invisible. LED do not lose much of the infra-red light as not much energy is burned off when it is on. LEDs appear brighter because these lights produce higher amount of light that can be seen by the human eye.
Lumens are the way to measure true light and should be considered while buying bulbs. In case you forget to look at the lumen output, your LEDs may be too bright for your rooms and spaces.
Colours influence brightness
The colour of the light or kelvin also impacts the brightness of bulbs. Most incandescent bulbs are 2700 kelvin and an LED of the same lumens will have similar glow but will definitely be brighter. Kelvin range from orange colour(2200 kelvin) to blue colour(6500 kelvin).
Steps to reduce brightness of LEDs
You can change the brightness of LEDs if it really bothers your eyes. If the bulbs you have at home are dimmable, pair them up with a dimmer switch. Dimmer switches reduce the brightness and remove unwanted glare. You can also use frosted lens that will help reduce light to bearable levels. Purchasing bulbs with frosted glass is another option.
