The Compact Fluorescent has been the most popular lighting choice for the consumers in recent years. When we compare this option with other lighting technologies available in the market, we find its performance better than all. It became the choice of the consumers in 1995 when it replaced regular incandescent bulbs. It was widely accepted due to its energy efficiency, better form of light, environmental friendliness and better lifetime. CFLs were accepted warmly because they outperformed a technology that had been a part of consumers’ life for almost 100 years.
What does it mean that CFLs must be a part of our life for the next 100 years? No, it is not compulsory. Is there any better choice than CFLs? Yes! We have the latest technology in our hands now.
It is Light Emitting Diode (LED). Whether it is a better choice than CFL or we are going to stick with our first love, the CFLs. Let’s take a look!
The LED Needs Less Power For Generating More Light
The unit for generating light is Lumens. In the following table, you will know how much light is generated against power. In simple words, we will get to know a number of Lumens generated against watts while we are using LED lights and CFLs in Pakistan.
|Incandescent||75||1100||13.33 Lumens/ Watt|
|CFL||20||1150||57.5 Lumens/ Watt|
|LED||12.5||1000||80 Lumens/ Watt|
The above figures confirm that we will have lower electricity bills and less generation of greenhouse gases when we will have LED lights in our houses and offices.
|Bulb||Lifetime in Hours||Replacement Frequency (40,000 Hours)|
It means that we expand less amount in buying bulbs, although the prices of LED bulbs are higher than the others because there is no need of changing these lights frequently. Less landfill is another benefit which we can avail with this advanced technology.
Impact on Human Health and Environment
|Mercury||No||Yes (≈ 5mg)|
|CO₂||7.3 kg/year (1300 lm @ 2 hours/day)**||4.4 kg/ year (1300 lm @ 2 hours/day)**|
|Ultraviolet Radiation Emissions||Yes||Low|
The above described calculations show the impact of LED lights and CFLs on the environment and human health. The environment will be less contaminated and hazardous materials will come into the atmosphere in less volume if we will have LEDs in Pakistan. The higher emissions of greenhouse gases and hazardous materials damage the accessories available in the room as well. The depreciation rate will be less than the normal for carpets, artwork and furniture, etc. if you will use LEDs.
LEDs Are More Robust
LED lights turn on immediately, while with CFLs, there is a delay. Heat emissions are the lowest with LED lights which means you will get a better room temperature inside. Due to these features, we consider LEDs more robust. As there is no triggering, the risk of migraines and epilepsy will be eliminated. These lights do not catch fire immediately and due to solid estate technology, there are no chances of breakage.
LEDs consume lesser energy than CFLs. As described earlier, the Lumens of 12.5 watt LED bulb is almost equivalent to 20 watts of CFLs. With 12.5 watts, 109.58 kWh in 24 hours will be consumed while with 20 watts of CFL, the value will be 175.32 kWh/ 24 Hours. In rupees, PKR 1434.40 will be your electricity bill for a year while with a CFL, the amount will become almost double and will be PKR 2294.60 in a year.
In short, LED lights proved to be a better option than CFL – at least, for the time being.
