Are LED Bulbs Now More Efficient Than Tube Lights

The advancement of technology has made our lives easier and more comfortable. Lighting is one of the most important aspects of everyday life, and there have been many evolutions in lighting.

Lighting is one of the most important aspects of everyday life, and there have been many evolutions in lighting. Nowadays, the technology which has been added to the list is the LED (Light Emitting Diode) technology. We shall discuss some facts and advantages of LED bulb over other forms of lighting.

As incandescent bulbs are inefficient as compared to fluorescent tube lights and CFLs (Compact Fluorescent Light), there is no point in comparing them with LEDs. So, the comparison is only among LED light bulb, tube lights and CFLs.


-LEDs are extremely durable and can last for 40,000 to 50,000 hours whereas the other light sources such as CFLs and tube lights last 10,000 to 20,000 hours. As such, the life span of such LED lights is more than double the life span of tube lights and CFLs.

-LEDs are unlikely to break easily as they are made up of plastic, unlike traditional light bulbs and tube lights, which are made up of glass.

The Energy efficiency:

-LEDs consume less energy and give more light. To emit 210 lumens of brightness, they consume 3W, while CFL light bulbs and tubes consume more than 5W. As such, LED lights are almost 65% more efficient than their counter parts.

-Also, LEDs are 95% energy-efficient. Which means, 95% of the power consumed by them is converted to light and only just 5% to heat.

They are eco-friendly and pleasant:

-LEDs do not contain any mercury nor do emit any carbon gases that are harmful to environment. They are "eco-friendly".

-Also, they do not generate any heat while working. They emit light the same as the natural day light and is pleasant. On the other hand, light from tubes and CFLs generate a considerable amount of heat, and the light from them is harsh to eyes.

The wide voltage range and ability to work in extreme weather: LEDs can tolerate extreme weather. And also, they are capable of working with a wide range of voltage. As such, the chances of failure are very less during voltage fluctuations. Also, CFLs and tube lights cannot withstand extreme weather and voltage fluctuations.

As you can see, super bright LED light bulbs now brings more benefits than CFLs and tube lights. In fact, It is fair to predict that LEDs are probably going to dominate the other two lighting solutions in future. However, the only drawback of LEDs is that they are a bit costly. Let's hope that manufacturers of these lights will make an effort to decrease the prices to encourage the buyers to adopt LEDs.
