Brilliant Bulb for Brighter Future

Have you ever wonder how to choose between different types of light bulbs?

Three common types of light bulbs available are Incandescent, Compact Fluorescent Light, and Light Emitting Diode.

Check out how eneryg-efficient light bulbs stack up against traditional bulbs.


Incandescent lightbulb works by heating a metal filament until it is white-hot. Incandescent bulbs produce mostly heat.

Compact Fluorescent Light (C.F.L)

The fluorescent lamp was designed to replace an incandescent light bulb. They don’t work well in cold temperatures, and they contain a little bit of mercury, which is a known toxic element.

Light Emitting Diode (L.E.D)

LEDs are the most robust since they don’t have a delicate filament or an outer envelope made of glass. They can operate well in cold weather.

Now you know a little bit about all 3 types of bulbs, let’s learn about the brightness, life span and estimation on electricity cost of each bulb.

Since we already know that LEDs are more energy-efficient, what other advantages that LED offers compared to other bulbs?

LED is extremely energy efficient with the most cost-effective option which has an extremely long lifespan (approx. 25,000 hours) compared to incandescent and CFL bulb.

Is it true that LEDs are the most cost-effective light bulbs?

Other than being more energy and cost-efficient, what else makes LED light bulbs better?

Better Light Distribution

LEDs have a better quality of light distribution and focus light in one direction.

Restrict Light Pollution

LEDs restrict light pollution and provide greater uniformity, providing superior light quality.

Reduce Energy Consumption

Fewer lights will reduce energy consumption and will, therefore, be a benefit to the environment.

Sustainable Development Goals of the United Nations

In line with Goal 7 from the Sustainable Development Goals of the United Nations, LED light bulb could help with the target to double the global rate of improvement in energy efficiency and has the potential to improve the overall quality of life.

Now that you know the advantages of LED lightbulbs, are you ready to switch?

What else can you do to support the global target of energy efficiency? Check out some tips here:
