Why cfl consumes less power

LED bulbs do get hot , but the heat is pulled away by a heat sink in the base of the bulb. Top 10 ways to conserve energy Adjust your day-to-day behaviors. Replace your light bulbs.

Use smart power strips. Install a programmable or smart thermostat. Purchase energy efficient appliances. Reduce your water heating expenses. Install energy efficient windows. Upgrade your HVAC system. A kilowatt-hour is 1, watts used for one hour. As an example, a - watt light bulb operating for ten hours would use one kilowatt-hour.

Below are some examples of electrical appliances found in most homes. These examples are using a 10 cents per kWh rate. Shape: LED bulbs are now available for almost any purpose. Category: automotive motorcycles.

The more lumens, the brighter the light. Are LED lights bad for your eyes? What is 60 watts in LED? How bright is lumens? Cost Winner: LEDs in the long run. Do CFL light bulbs cause cancer? Is CFL harmful for eyes? Have a query about the amount of energy used by various types of light bulbs?

So when electricity passes between the cathode and anode inside the bulb, a chemical reaction is induced and produces ultraviolet light and heat. The color of the light changes depending on the inert gas inside the bulb. To produce different colors of the spectrum, many CFL bulbs are filled with different inert gases in different proportions to produce required colors.

The Light produced by CFL bulbs have a longer wavelength. If you are familiar with wavelength and energy, you might know that energy and wavelength are inversely proportional. Light Emission Diodes or LED's produce light without the intervention of a chemical reaction or need of any gas or mercury vapor.

LED's have semiconductors which produce light when electrons travel from anode to cathode. The name itself indicates that it is a diode which emits light when electricity passes through it. Since the electrons move constantly the emitting diodes will emit light with an average lifespan of 50, hours.

LED's emit light in shorter wavelength and thus are more energy efficient. Since there is no need of a complex chemical reaction, LED's use less energy as it is based on the movement of electrons , more energy efficient and do not heat up as traditional CFL bulbs do. Though LED's are little pricey when compared to CFL, the annual energy savings and considering the replacement savings are much higher when you consider a long-term period.

You may require replacing CFL very frequently and their energy consumption is also very high, but LED's power consumption is less and you need not replace them as frequently as you do with CFL. Points: 2. LED light don't require more electricity to do its job of emitting light. It gets heated up quickly and illuminates the areas whereas CFL lights use more energy to get heated up.

CFL light is also dangerous to the environment and paves way for Global Warming. These days due to government initiative luckily the prices of LED Light have come down and is in reach of every common man. Points: 8. The first replacement for the regular incandescent bulb is the compact fluorescent bulb. But today in the market the best available bulb is the light emitting diode LED bulb. If you compare the efficiency of these bulbs a As there is a chemical reaction involved in CFL the bulbs will get heated up very fast and a lot of energy will be wasted in this process.

Compact fluorescents are being used in residential applications replacing incandescent and halogen lights. They provide relatively shadow-free lighting in residential applications and because of their small size can fit nicely into sconces, ceiling lights and table lamps.

LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Efficiency —While incandescent bulbs and CFLs generate most of their energy in heat, LEDs are cool to the touch—which translates into less wasted energy.

Disadvantages High initial price: LEDs are currently more expensive price per lumen on an initial capital cost basis, than most conventional lighting technologies. Temperature dependence: LED performance largely depends on the ambient temperature of the operating environment — or "thermal management" properties. Normally colors dont figure in energy consumption of an LED. Though the voltage drop in red led is of about 1. However it is the current consumption which governs the power consumption.

LED's are constant current devices and can be lit with currents in the range of mili and micromili amperes. LED light can damage eyes , health authority warns. The "blue light " in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness. It is brighter because LED delivers same or better brightness at less electricity consumption and when used equivalent to the watts of CFL ,definitely it is brighter and efficient!

The safest type of light bulbs for overall health are simple incandescent bulbs. Although they are less efficient than their counterparts the LED and CFL light bulbs , emit far less blue light and produce less dirty electricity. LED bulbs are way better than CFLs simply because they are durable, energy efficient, environment-friendly and emit less heat. They do not contain harmful substances like mercury and are more cost-effective.

They also use less power per unit of light generated. Unlike other energy-efficient types of lighting , the LED bulb does not emit polluting radiation and therefore does not pose a health hazard. It is important to note that LED bulbs operate at low voltage and are therefore considered safe compared to any other lighting systems LED operates at low DC voltage 12 V.

The components of an LED and the way that they generate light significantly extend the lifespan of these bulbs. Energy efficiency. High brightness and intensity. Exceptional colour range. Low radiated heat. Instantaneous illumination.
