Which light is better: CFL or LED

Which light is better: CFL or LED

“Darkness cannot drive out darkness, only light can do that”, a quote stating the importance of the existence of light. A dark house can lighten up only by the availability of resources like a tube light, bulb etc. Nobody realizes the worth of what they have until they lose it. A power loss during rainy seasons can make a person realize the worth of the resources they possess.

A bulb basically is a smaller version of a tube light. It can be used to lighten up small spaces like the kitchen, bathroom or in a warehouse. With the advancement in technology, there are innumerable types of bulbs developed by the engineers. Every time something new is developed, the developers keep in mind of making it better than what they had developed before. While developing a bulb, the parameters taken into account are power emitted, budget-friendly, environmentally friendly, a lifespan of the bulb.

Every technology that is manufactured comprises of both advantages and disadvantages. There are technologies that may be better off than others but there always exists a downfall in them too.

CFL stands for Compact Fluorescent Light or Compact Fluorescent Tube. It is a mini version of the standard fluorescent light bulb.

CFLs produce light differently than incandescent bulbs. In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

CFLs need a little more energy when they are first turned on, but once the electricity starts moving, CFLs use about 70% less energy than incandescent bulbs. This entire process typically takes 30 seconds to 3 minutes to complete, which is why CFLs take longer than other lights to become fully lit. CFLs with decorative covers like globe or reflector shapes have a unique design challenge that results in the trade-off of a slower warm-up time, which is why these CFLs take longer than bare spirals to reach full brightness.

Few of the advantages over LED lights are stated as follows:

  1. It is budget friendly.
  2. The lights radiate evenly in all directions.
  3. It is available in different shapes and sizes.

There are various drawbacks faced by the CFL bulbs. Some of them are stated below:

  1. The primary disadvantage to CFL lights is the mercury contained in the bulb. This is ordinarily not a problem, but if the bulb breaks clean up is a hassle. Mercury is a dangerous heavy metal, and proper cleanup and disposal of CFL bulbs are critical. Never put a used CFL bulb in with the rest of your trash. Contact your local waste management company to learn how to properly dispose of used CFL bulbs.
  2. It has a shorter lifespan as compared to LED lights.
  3. It is sensitive to extreme temperatures and hence it cannot be used for any outdoor purpose.

LED stands for Light Emitting Diode. It is a semiconductor device that emits light when current is passed through it. Light is produced when the particles that carry the current (electrons and holes) combine together in the semiconductor device. LED’s are described as solid-state materials. The light emitted is not particularly bright. There are a few applications of the LED bulbs used, they are Remote, indicator lights, fiber optic data transmission etc.

It has a few advantages over the CFL bulbs used, they are stated below:

  1. Low power requirement
  2. It has a longer lifespan than CFL bulbs ( they last four times longer than CFL bulbs)
  3. They are available in multiple options such as: ‘warm white’ that is used for warm lighting and ‘cool light’ for general lighting.

Few disadvantages to list are:

  1. It is expensive as compared to CFL bulbs.
  2. Light doesn’t radiate in all the directions.

 

When it comes down to concluding that out of the two which is more effective and better than the other, it becomes a tedious task. Each of them has their own positives and negatives. According to me, both of these bulbs can be effectively used in our households. CFL bulbs can be made use in the bathrooms, kitchens or storeroom. These bulbs are cost-effective and use of power decreases after a period of time. And on the other hand, LED’s can be made use for decorative purposes like Diwali lights or it can be also used for household purposes. Hence, Choose smarter be smarter. Now you can understand which is good for you.
