21st century, if written in history, would be known as century of technological inventions. There are not a single place where technology is not present.

Bulbs are also affected with technology. Initially, there were incandescent light bulbs, and then came CFLs with more capabilities and now LED bulbs.

Incandescent bulbs are burning out, and it’s a good time that you should consider replacing these with LED. Though, LED are high in price but at the same time it comes with high durability, long lifespan, easy handling and many more benefits.

If you are taking LED bulbs for household purposes or office, there are so many options. It is important to choose the best LED. You should look for the size, shape and configuration of LED bulb, as well as its intensity and color.

But before buying, make sure to look for the quality of LED bulb, which are as:

1.  Lumens(lm), not Watt

When you shop bulbs, the first thing which stand in front of you is, Watt. To determine the brightness of bulb.


Is it so? No, it isn’t.

Watt is for energy consumption.

So from now on, look for the lumens factor of bulb.

For example, an LED bulb with 8 to 12 watt gives brightness as of 60W incandescent bulb.

The lumen (lm) is the factor of brightness and also the number you should look for when buying LED’s.

A chart below can make you understand it in an easy way.


As you can see from the above chart, a standard incandescent bulb draw up to four to five time as many watts for the same lumen number.

So this factor is one of the important factors in choosing the best quality of LED bulb.

2.  Color Temperature

Initially, LED’s were mostly comes in a very much higher color temperature (bluish light) as compare to typical  2700K color temperature of a warm white incandescent lamp. It led many people to think that LED’s gave a “Cold” light.

LED technology has emerged great in the last couple of years and some types of LED are available in a range of color temperatures from warm white (2700K/3000K) up to daylight (6000K and above).


LED’s with a higher color temperature tend to be slightly more efficient than those which have a lower color temperature.

A color temperature of 2700K to 3300K is preferred to replace the standard incandescent bulb.

3.  Non-dimmable LED’s

The dimmers, which were designed to work with incandescent bulbs. It works by cutting the electricity amount sent to the bulb. Light would be dimmer if less electricity will be drawn. But with your newly acquired knowledge of LED, you know that there is no direct correlation between LED brightness and energy drawn.

The guide explains why some LEDs will flicker, hum or buzz when tied to a dimmer.

If you’d like your LED to be dimmable, then you should try these things:

Find LED bulbs which are compatible with traditional dimmers, or try replace your current dimming switch with a leading-edge (LED-compatible) dimmer.

When you choose to buy an LED bulb, it can help you to know what kind of dimming switch you have, but if you have no idea then try to search for LED bulbs compatible with standard incandescent dimmers.

4.  Heat Output

LEDs give off relatively little heat than other. At the same time it do run a bit warm and often incorporate with a heat sink to dissipate any excess heat and maintain the LEDs at operating temperature.

5.  Life of LED

It is one of the main point of LED that makes it more useful in current time.

It’s Lifespan.

It ranges from 20,000 to 50, 000 hours, which is almost 20 to 50 times than a standard incandescent bulb.

The maintenance and extra charges are not so much for LED bulbs.


LED bulbs are the technology, which stands at first when it comes to the bulb.

Never compromise with the quality of an LED bulb.
