Can switching to LED light bulbs help you increase energy savings?

The simple answer is yes. LED light bulbs can help you save money on energy and in this article we will present simple calculations that with explain just about how much can be saved.

But let’s start from the beginning to understand the difference between LED and incandescent bulbs.  LED (light-emitting diode) bulbs, use a semiconductor to convert electricity into light. LED lights produce light more efficiently as they emit light in one direction, compared to standard incandescent light bulbs or compact fluorescent lamp (CFLs), making them less expensive to use.

LED lights gained huge popularity since year 2000 when the initial technology faced many issues like short lifespans, harsh lights, flickering and high price tags. Since then, the quality of the LED products increased significantly and the light bulb prices have dropped by 85% in recent years.  But yet not everyone has switched to LED lights and we are hoping this article will help you better understand the benefits of replacing your incandescent bulbs with LEDs.

Besides the energy savings, here are some other benefits of LED light bulbs:

LED Light Bulbs Last Longer.

High-efficiency LED bulbs last at least about 10 years while incandescent and halogen bulbs last on average one year. This provides savings in not only purchasing a lot less bulbs, but what’s more important – replacing them.  The task is not always easy when your house has vaulted ceilings or hard to reach light fixtures. 

Many Color Options.

While incandescent bulbs use gels or filters to create different shades of light, LED lights provide a range of colors and temperatures using the actual diode or its phosphorus coating. This allows you to enjoy many different colors that LED bulbs can offer. 

LED lights do not cause heat build-up.

LED lights do not cause heat build-up as only 20% of a LED light’s energy is used to emit heat.  They are generally cool to touch and you don’t have to worry about them being a fire hazard in case they tip over and touch the shade.
