High electricity bills can be solved if you understand how lights work. If your house is filled with incandescent bulbs, then there’s an easy solution. LED lightbulbs conserve energy much better without losing any change in the quality of your lights.

Change a Light Day is all about making impactful change through minor actions, as switching from an incandescent lightbulb to an LED lightbulb can help save energy and money, and ultimately, the environment.

Learn about Change A Light Day

Change A Light Day was created so that people could be encouraged to make just one small change in their home that would result in them consuming less energy. Did you know that by purely changing one light bulb in your home you could then reduce your carbon footprint and lower your energy bills in the process? That’s how impactful making the switch to LED lightbulbs can be.

LED lighting is ideal for all circumstances, be it for the home or business. This is because the benefits of this type of lighting are so widespread. We’re going to talk you through them so that you can see just how important Change A Light Day is! There is only one place to begin, and this is with the energy efficiency of industrial, domestic, and commercial LED lighting. When compared with incandescent bulbs, LED bulbs consume up to 90 percent less power.

You will save money too! This leads on from the former point. As LED bulbs use less power, you can expect to save a considerable amount of money on your utility bill. This is why so many homeowners choose LED lighting, as it reduces expenditure so they can use the money to spend on other aspects of their property.

Another key benefit associated with LED lighting is the fact that it has a long life span. In fact, LED bulbs and diodes are expected to last for up to 100,000 hours. This is 11 years of operation if they are in continuous use, which is unlikely to be the case, so you can expect to get a lot longer out of them.

LED lighting produces barely any UV emissions and little infrared light. This means that LED lighting can be used in areas where there are materials and goods that are sensitive to heat. This makes them a good choice for archaeological sites, art galleries, and museums, as the LED can illuminates UV sensitive materials and objects.

Last but not least, LED lighting is ecologically friendly. These lights are free from toxic chemicals, whereas most conventional bulbs contain numerous materials that are bad for the environment, such as mercury. When you take all of these benefits into account, it is not hard to see why LED lights are championed so much, is it? If you’ve not got LED lightbulbs in your home at the moment, we’re sure you will want to be part of the trend on Change A Light Day.

History of Change a Light Day

Change a Light Day began back in 2005 in the state of Kentucky, when the Kentucky Office of Energy Policy decided to encourage Govoner Ernie Fletcher and his wife to proclaim this day as Change a Light Day.

The office invited the First Lady Glenna Fletcher to kick off the day, hosting a public event at the governor’s mansion with students from local schools and representatives of Energy Star to celebrate the day.

Throughout the state of Kentucky, people were encouraged to change at least one lightbulb in their home to an Energy Star model to help produce lower electricity rates and save money.

Now, as the holiday is still celebrated to this day, Kentuckians switching to more energy-efficient lightbulbs has helped preserve energy sources and protect the environment.

LED bulbs use less energy and cut into utility bills, as it produces light with 90% more efficient than incandescent light bulbs. By switching from incandescent to LED, it helps reduce carbon emissions, decreases greenhouse gas emissions, contains environmentally safe materials, and has a longer lifespan. Change a Light Day is all about switching at least one light in the house to an LED light.

This holiday isn’t just for the state of Kentucky, but for those who care about the effects that incandescent light bulbs can have in landfills, switching to LED lights can benefit everyone in the end. So, if you care about the environment, begin by changing some lightbulbs in your house for the better.
