What Determines the Brightness of LED bulb

By April 21, 2016Uncategorized

Time is changing, so is technology. Initially, people had only single choice of using incandescent bulbs.

The option of Lighting have improved greatly since incandescent bulbs first came around. And then came CFL’s (Compact Fluorescent Light) and LED’s (Light Emitting Diode).

13LED bulbs convert most of the energy into light, whereas the regular bulbs producing small amount of light after using lots of energy.

It’s not necessary that you settle for CFL bulbs which takes 30 seconds to warm up before turning on fully whereas LED bulbs turn on immediately. One more important factor of LED bulbs is that, they last for approximately 10 years, which makes homeowners life easy as they can keep their ladder away for a long period of time. In case of regular bulbs, you have to worry about the defect or replacing the bulb.

On comparison with incandescent and CFL’s (Compact Fluorescent Light), LED bulbs are more efficient and environment friendly.

LED bulbs are getting better with days. They are brighter, last longer and medium of less expensive electricity cost.

Why LED is Ideal

LED’s, have a huge role in electronic circuit due to its unique features over bulbs. Some important features that make LED ideal in electronic circuits are:

  • LED bulb being encapsulated inside resin or plastic cases can withstand mechanical shocks.
  • LED bulb do not generate loss of power and heat.
  • LED bulb needs low current and voltage that is 20 Milliampere current and 1.8 Volts.

Before having an LED bulb, make sure you have all the knowledge about it.

Are they Good to buy? Will they give you cooler & brighter light at low cost?

These questions are very common among people, so why not light bulbs should be given a chance to answer your question.

Whether you are at work or at home, you want brightness. You want that your surrounding should be clearly visible.

Brightness is one of the most important aspect of LED. A Human Eye have the ability to be able to see the light which is near 550NM region of Green-Yellow part of the visible spectrum.

Now you get an idea about LED bulbs and regular bulbs, it’s time to know the brightness factors of LED.

The basic factors of determining the brightness of LED bulbs are as below:

1. Watt:

Don’t get confused with Watt. Watt is for determining the energy consumption by light source. Higher the wattage, higher would be electricity cost. The watt is a derived unit of power. It specifies the rate at which electrical energy is absorbed. The symbol of watt is (W).  Example of watt is Leaving a 100-watt light bulb on for 10 hours consumes 1 kilowatt (kWh) of energy.

2. Lumens:

Factor which is by far the most important aspect in determining the brightness of bulb is Lumens. Or In simple words, Lumens (Lm) are a measure of total amount of light emitting from a light source.

It is clearer with the help of above specified image. You can see clear difference among incandescent, CFL and LED bulbs. Higher the lumen rating, brighter the bulb would appear.

3. Kelvin Scale

The Kelvin scale is that scale which measures the color of the bulb. The Kelvin scale ranges from 2500K (Warmer) up to 6000K (Coolest). The Higher the Kelvin value of bulbs, the closer the light output would be as of sunlight. Having Kelvin Value of 3500K or less than that, indicates the amber hue. If the Kelvin number ranges between 3500K to 4100K, it means the output of light is white hue. Output of light will be blue hue or as of sunlight, if the kelvin number would be 4200K or above 4200K. You can now check the Kelvin scale as shown in below image.

Nowadays, one of the best ways to reduce your electricity bill is to use Energy Star Compact Fluorescent Light bulbs i.e. CFL or the Light Emitting Diode bulbs i.e. LED instead of Incandescent light bulb.

So, here we conclude with this saying that…

LEDs are the longest heat enduring bulbs available, runs approximately 10 years which is around three times longer than CFLs.

11We are living in the time where everyone needs lights. If you are conscious about energy usage and your wallet. We at Rallison Electricals Pvt. Ltd. tend to provide you with most effective solution of your electricity bills.

Light your house and workplace with Rallison LED bulbs.
