LED lighting: The future of lighting technology

We all know what is the future of light energy sources: LEDs. Gradually, this light device has replaced fluorescent, halogen, and filament bulbs all over the world as LEDs are highly efficient and consumes less possible. What are these and how are they so efficient?

LED stands for Light Emitting Diode which is a semiconductor material that converts electric energy to light energy.

The energy consumption of an LED light is 85% less than incandescent or halogen lighting. Unlike the incandescent bulbs that use a thin wire filament for the passage of electricity and the halogen bulbs that pass energy through mercury vapour to emit UV light, LED lights use a semiconductor device that converts the electrical energy passed on it into light energy.

Being super energy efficient, LED lights help in reducing your power bills. LED lights have a comparatively longer lifespan and becomes bright instantly on switching on. They are currently the most efficient source of illumination and are hailed as the future of lighting technology owing to the fact that they consume very less energy and can be charged using a low energy power source like solar cells.

Why should you use LED lights?

1. The first and foremost reason why one should use. LED lights is because they consume very less energy compared to other lighting sources. They can massively help in reducing your annual electricity bill.

2. LED lights have a longer lifespan. Usually, they last for about 25-30 years.

3. When switched on, they light up instantly and you do not have to put up with the problem of dim lighting in the beginning.

4. Unlike CFLs, LED works well even in low temperatures.

5. Early LEDs were quite expensive but with the rapid growth in the marketing of LED lighting in Singapore, the prices have gone down. You can get the latest LED tubes and lights online at an affordable range.

6. LED lights offer reduced heat output.

7. They offer deep saturated colour in light without filters.

8. There are a variety of colours and lights to choose from.

9. They help the environment by consuming less energy, as the world's majority of electricity comes from fossil fuels.

Factors to consider before buying LED lights
It is time you must switch to the cost saving lighting technology, LED lighting which after significant advances over past few years now provides the warm light that incandescent lights have been providing us since decades. Since there are varieties of LED bulbs and tubes available in the market of Singapore, choosing an LED is not the same as picking up an incandescent light source. Therefore, there are a few things you must consider before heading to the store to buy an LED.

1. Research about the varieties: The first thing you must do if you are thinking of buying an LED light is doing an online research about the available options. Because of a large variety of choices, it is completely different from buying a regular incandescent bulb. Thus, a complete knowledge about the specifications is essential. You must then choose the LED light that meets all your needs and the space that needs to illuminated.

2. Brightness:
As opposed to the belief that wattage is the measure of brightness of a bulb, the real unit of measurement is lumens. It provides the real measurement of the brightness of the light source and this is the number you must look for while you are shopping an LED. Most popular brands mention this in their online stores or sites.

3. Choosing the colour of LED:
Choosing the right colour of LED light can be challenging because it is known that incandescent bulbs provides a warm yellowish tinge of light, but LED lights come in a variety of colours. Warm white, soft white and bright white are the most popular colours of LED available in the market. Whereas the warm and soft white lights provide a colour similar to that of incandescent bulbs, bright white lights are whiter, like the daylight. For homes, you must go for the ones similar to the regular bulbs, that is the warm white and soft white colours. Do consider the colours of your walls.

4. Colour temperature:
Technically, the colour temperature is measured in Kelvin. The lower the Kelvin value, warmer or yellowish is the colour. A typical incandescent bulb has a Kelvin number of 2700-3000K. With this range in mind, you can shop for the colour that you wish to buy. A major difference between the high and low quality LED lights can be the consistency of colour temperature of the multiple products.

5. Direction of light:
When it comes to direction of light, the semiconductor device in the LED source emits light in one direction only contrary to the incandescent lights which emits light in 360 degrees.

6. LED fixtures:
Most of the manufacturers claim that their LED lamps have a lifespan of 20 years and more. This statement holds true if the LED fixture is designed in an effective way to not let the LED heat up.

7. LED compatible dimmer:
Not all LED lights can be dimmed. So, if you want your LED to be dimmable, you must find an LED bulb which has a proper compatibility with traditional dimmers. You can also substitute your current dimming switch with an LED compatible dimmer. When you are shopping them, you can simply search the LED bulbs compatible with traditional incandescent dimmers.

Why is the future bright for LED?
1. Statistics made by the six major Southeast Asian countries which includes Singapore show that the marketing of LED lighting has grown significantly and is expected to grow further in the coming years. Singapore is the most developed country among the other Southeast Asian countries and has shown the fastest growth in usage of LEDs, even though developing countries like India benefit the most from it.

2. In the early days, the biggest obstacle on the path of adoption of LED was its high pricing. Over the years, there have been significant advances and lowering of prices which has made it a lighting source for homeowners as well as multinational companies.

3. With the LED lighting becoming mainstream, the organic LEDs (OLED) are now coming up which are made of layers of organic semiconductor devices. It is predicted to have a mass marketing in later years, but is currently being used in TVs and mobile phones.

4. Currently most of the LEDs offer about 115 lumen per watt but gradual advances made by manufacturers have demonstrated that they are capable of producing 200 lumen per watt.

The LED wave is huge in Singapore and in all other countries. This is because it is a better option. Get your homes lighted up by the LED lights to help in reducing the energy consumption, while significantly reducing electricity bills along the way.
