5 Best and Worst Light Sources for Your Eyes

LED Lights

There are many factors that add to the strain a light bulb causes on your eyes. Mainly the type of the bulb is of keen importance. Older bulbs had a large quantity of UV rays emitting from the filament which was very harmful to the eyes. Other factors of light being harmful to your eyes are lumen, watts and the color temperature of the light source. 

How many lumens do I need to need?

Lumens apply to the sum of light radiated or the strength of the light bulb. Linked to watts, the higher the lumens, the brighter the light. To understand how many lumens you require, you must first find the square footage of the space or place you are attempting to illuminate. 

1-The Incandescent Bulbs:

 The typical bulbs are incandescent bulbs. Through an incandescent lamp, the filament of tungsten glows as the current flows through it, lighting the bulb. The filament of tungsten is surrounded by vacuum or nitrogen gas. The bulbs are available in various shapes, including GLS, globe, candies, mushrooms. However, the rapid flow of current allows the filament to heat up and flame out. Incandescent bulbs only run for 700–1000 hours and trigger electricity loss.

Incandescent bulbs have been the most popular type of bulbs in buildings since the advent of lamps and have only lately been substituted by modern technologies, including LEDs, Fluorescent and HID bulbs. You can look up Lepro for the best LEDs.

2 – Fluorescent Lamps:

Fluorescent lamps are more nuanced than incandescent bulbs. In a fluorescent light, electric current flows through cathodes, exciting mercury and other gasses that are packed within, radiating energy. The phosphorous film on the exterior transform’s radiant energy into visible light. Fluorescent lamps require less energy to emit the same amount of light and can last longer. But because of mercury filling, they are impossible to dispose of.

3 – Compact Fluorescent Lamps (CFL):

The CFL is designed to substitute incandescent bulbs in homes and industrial buildings. Working on the concept of fluorescent bulbs, the CFL generates the same quantity of light with less fuel. It consists of several tubular loops, packed with mercury, and resembles an incandescent bulb.

Compared to incandescent bulbs, CFLs have a longer lifetime of up to 10,000 hours, are more energy efficient and have a better luminous quality. But the mercury in the loops makes it impossible for them to dispose of it.

4 – Halogen Lamps:

Halogen lamps are an improved version of incandescent lamps in which tungsten filament is wrapped in a compact, transparent envelope. The bulb takes its name from the filling of a small quantity of halogen with an inert gas. Inert gas increases the bulb’s brightness and lifespan, resulting in higher luminous efficiency. These lamps are also smaller in size compared to the incandescent lamps.

5 – Light Emitting Diode (LED):

Due to their energy efficiency and a variety of light colors, LED bulbs are becoming increasingly common. LED is a semiconductor device in which electricity is applied to a negatively charged diode, resulting in electron flow and photon release. The photons are combined to emit light from the diode. You can find LEDs for homes or as LED tube lights from https://www.lepro.com/led-tube-light


Throughout the ages, we have seen many kinds of light bulbs illuminating our homes and the streets, LEDs are the most advanced lighting technology till date and proved to be the most beneficial light source for your eyes.
