The debate between LED and CFL bulbs has been an ongoing one for a long. Lately, both have emerged as popular choices for your home lighting systems. But, to choose the most suitable one for your needs, it is essential to understand the differences between both, along with the advantages and disadvantages. So, let’s get started.



Instead of generating heat and light, LED lights function by producing light through diodes and semiconductors. Positive and negative ions meet in these semiconductors to cause electrification. 
CFL bulbs function as fluorescent light, filled with argon gas and mercury. As a result of passing electricity, these bulbs emit ultraviolet light that reacts and produces visible light. 


In terms of efficiency, LED bulbs work better than CFL because they use maximum energy utilised in light production. On the other hand, CFL bulbs use as much as 80% of the energy for heat generation. Additionally, LED lights also consume less power in comparison to CFLs. 


LEDs offer directional lighting, and CFLs radiate it in all directions. Therefore, the brightness and lighting properties are more in LED lights. As a result, they are more suitable for spaces such as home offices, bathrooms and kitchens. 


This factor determines the light’s colour, measured on the Kelvin scale and can be used to modify the look and feel of spaces. Both these kinds of lights are available in various colour options. However, exposure to blue wavelengths of LED lights under dark settings can affect the body’s cardiac rhythm and sleep schedule.

Life Span

Generally, LED lights outlast CFLs because they have a lifespan of 25,000 to 50,000 hours. In comparison, CFLs can only last for around 8000 hours. In addition, turning the light on and off frequently can also reduce lifespan. So, while LED lights are initially more expensive, they help to save replacement costs and energy. 


The initial investment in LED lights is more than CFLs. While LED bulbs cost around Rs. 700 for a pack of 6, CFLs can be bought for Rs. 550. But, in the long term, LEDs are a better investment as they last longer, help save energy costs and reduce frequent purchase requirements.

Health Hazards

The mercury content in CFL bulbs is considered to be hazardous to health. In case of these breaking, one must dispose of them properly. Likewise, LED bulbs are made from toxic materials like arsenic and lead that can contaminate the land and water.


Generally, switching to LED and CFL lights is convenient and does not require much modification to existing features. However, changing the dimmer switch might be a necessity. The same can be done by reaching out to an electrician.


In cases of outdoor usage, one needs to be very cautious with CFL bulbs. These must be placed in an enclosed fixture to protect from temperature changes. On the other hand, LED lights do not come with any such restrictions.

Pros and Cons - LED VS CFL

Let’s look at the information with an overview of points that will help you make the final choice for your lighting setup.

LED Lights Pros

  • With a longer lifespan, LED lights offer more longevity
  • These are comparatively efficient and cool to the touch.
  • Other advantages include more diminutive size, temperature-withstanding ability, outstanding durability and reliability.

LED Lights Cons

  • The initial investment in an LED light is comparatively expensive upfront.
  • The colour quality of LED lights may appear stark in comparison to incandescent. Hence, one should always look for the ‘lighting facts; label before selecting a LED light.

CFL Lights Pros

  • These are affordable in comparison to LED lights. The initial investment is much lesser.
  • There are no specific restrictions in terms of the colour quality of the lights.

CFL Lights Cons

  • The mercury content of CFL lights is a significant concern for many people, considering that mercury is a neurotoxicant.
  • There are several limitations to the usage of CFL bulbs. These are not dimmable and inefficient in recessed lighting. Outdoor use also becomes a problem with CFL bulbs.


When it comes to choosing between LEDs and CFLs for your lighting setup, there are some key factors to be taken into consideration. Analyse your needs closely. If you are searching for a durable and energy-efficient option, LED lights are the winner. 
However, if you have any budget constraints and want an affordable option, opt for a CFL bulb. They still last for a reasonably long time, are energy efficient and will cost you less. Ultimately, the final decision depends on your needs and the setup where the lighting is required. Both options have their pros and cons. So, it’s better to go with what fits.
