LED lights are the up-to-date technology in effective energy lighting. LED stands for ‘Light Emitting Diode’, which is a semiconductor device that converts electricity into light.
LEDs were originally developed years ago for use in expensive electronics products such as laboratory and electronics test equipment, and then were later used in circuit boards, TVs, radios, telephones, calculators, and watches. In the past LED light were very expensive to produce and were not commonly used.
But since the first visible LED was created in 1962 the technology has grown rapidly, with LED lights becoming an extremely popular lighting solution in recent years, and a main reason for this is, that the price for LED Lights has become much more reasonably priced.
What is LED Lights – Do LED lights save energy ?
Yes, LED bulbs do save energy, mainly because the actual bulb wattage is lower for the same light output as other types of bulbs, but also because LED lights burn cooler and therefore will save on air conditioning costs.
When comparing LEDs to traditional lighting technology, the improved energy efficiency and longer lifetime result in a significant long term savings of your energy cost. As previously
mentioned, LEDs use up to 90% less energy than incandescent (including halogen) and 60% less than old fluorescent lighting, resulting in fast energy cost savings.
On top of this, the long lifetime of LED bulbs means that they need to be replaced far less frequently, and further reducing any additional maintenance costs. Investing in a full LED transformation may seem expensive at first due to the investment required. However, the subsequent savings will mean that this extra investment is soon repaid.
What is LED Lights – How much energy do LED lights save ?
The quantity of energy that LED bulbs saves differs, but it’s usually anywhere from 20% to 80% because of the reduction in electricity.
Furthermore LED lights also have a much longer lifetime than other types of lighting – see the table below.
Lighting technology – Estimated lifetime
LED 25.000-50.000 hours
CFL 8.000-15.000 hours
Halogen 1.000 – 5.000 hours
Incandescent 1.000 hours
What is LED Lights – Why do LED lights last longer than other bulbs ?
LED bulbs last longer for several reasons. Initially, LED bulbs do not have filaments which create a large quantity of heat. Also, there is no metal fatigue, no oxidation, and no evaporation of metal components.
LED bulbs are far less sensitive, and are very rugged, solid-state devices with no glass to break. All these types of features gives the LED bulbs a much longer lifetime than you have with other light products.
What is LED Lights – You will pay more for an LED bulb
LED bulbs are like hybrid cars: cheaper to run but more costly upfront.
When changing to LED bulbs, don’t expect to save big amounts of cash in the start. You should instead look at the change to LED bulbs as an investment. Fortunately, the competition in the LED business has increased in the recent years, and therefore the pricing for LED bulbs have come down in price. However, you should still expect to pay more for LED bulbs than for an incandescent bulb.
But in the longer run the higher start up costs for LED bulbs will pay off, because in the future you will have less heat production, longer bulb life, which will save you a lot in electricity costs and new bulbs.

What is LED Lights – Do LED lights look as good as ordinary lights ?
In my opinion LED bulbs look just as great, and in some cases better than incandescent bulbs. Nowadays there are so many options for color choices with LED lights, and you can select your LED bulbs to fit your tastes and needs for almost any use and place in your home.
What is LED Lights – How do I know if I’m picking out the right LED bulb ?
Choosing the correct LED bulb can sometimes be a little tricky, if you are not familiar with LED lights.
First you need to know what bulb type you are replacing, and next you can pick out a replacement bulb or component to put in its place. It is also important that you make sure to get the correct color of the LED bulb to cover the light output, that you want. The popular colors available for LED lights are typically “warm white” or “soft white,” and “bright white.”
Warm white and soft white will produce a yellow hue, close to the color you see at ancandescent bulbs, while bulbs described as bright white will produce a brighter light, closer to daylight and comparable to what you see in retail stores.
If you want to get a bit more technical, light color LED’s (color temperature) is measured in kelvins (K). The lower the number is, the more comfortable (more yellow) the light will look. To compare, a typical incandescent bulb is somewhere between 2,700K and 3,500K. If that’s the color you want, then look for this range while you go shopping for LED bulbs.
Summary of LED Lights
LED lighting has various benefits when compared to traditional light solutions:
- Energy-efficiency – LED bulbs are far more energy efficient when compared to the traditional alternatives with energy savings of about 70-90% of electricity compared
to incandescent or halogen lights and up to 50% in comparison to fluorescent lamps.
- Longer lifetime – LED bulbs last 2 or 3 times longer than fluorescent bulbs and over 50 times longer than incandescent lamps. The typical lifetime of an LED light is up
to 50.000 hours.
- Quick light – Many fluorescent lights can take a while to ‘warm-up’ and reach their full brightness, however LEDs lights up immediately.
- Eco-friendly – LED technology has the potential to dramatically reduce carbon emissions, and as around 20% of the world’s electricity is used on lighting, then finding a more energy efficient solution will reduce this issue. In addition, as LEDs don’t contain mercury, removal of the bulbs is much easier and cleaner. So LED bulbs
indeed support our environment.
- Lower heat output – Unlike filament bulbs, an LED lamp does not project infrared heat in its beam, making them more appropriate for lighting heat-sensitive objects like
artworks or food. As LEDs produce less heat they are also ‘safer’ than traditional bulbs, reducing the risk of fire caused by high temperature bulbs.
- Added durability – LEDs are a solid state form of lighting, meaning they are able to resist lower temperatures and higher levels of vibration and shock in comparison to
incandescent or fluorescent lamps.
