Just before the wide appearance of CFL in market, people were asking what are the advantages of CFL?
Now the time has turned and conversation moved to LED lights. Customer wants to learn comparison of CFL and LED lights in easiest way.
We have made an Infographic for easy understanding.
Comparing Life span:
During comparison of LED and CFL light, the very first thing comes to mind is Life. A well built LED light can maintain (70%) of its brightness even after 50000 hours. It doesn’t go off after that, but illumination decrease afterwards. CFL bulb also becomes little dim, but after its life (8000-10000 hrs), it goes dark.
LED bulbs or lights have higher efficiency for converting power in to brightness. High efficiency CFLs are also available, but they cost very high. You can replace CFL bulb with LED of half power. It will save 50% of your electricity bill over CFL.
Following is the LED vs CFL light comparison Chart shown as Infographic:
Now let’s check lifetime calculation. LED lights costs more initially, but you are free from hassle of changing bulbs. Overall consideration of power, life and cost says CFL costs you more in long time basis.
Also consider factors like vibration, on-off cycles, humidity and breakage that can make your CFL lights expired before 8000 hours.
Now consider practical example of 50W CFL and 20W LED light used over 10 years of span. If we consider daily usage of 8 hrs, (and Rs.7 Unit charge) then Cost of LED Light (Initial investment) will be covered within 3-4 years. At the end of 10 years, total cost savings of using led light will be around Rs. 5000. You can use our led light cost savings calculator to compare Energy costs and savings of CFL and LED lighting in Indian rupees.
