Benefits of LED Lighting - LED vs CFL and Halogen

You're probably wondering: Why should I use LED lighting over all the other options out there? An honourable query, indeed, and we are here to help. Firstly, let's have a look at the basics:

What is an LED?

LED stands for Light Emitting Diode. What differentiates the LED from Halogen and CFL lighting, is that it emits light via a solid object (a semiconductor) rather than heating up filaments and using gasses. This technology is the backbone which grants LEDs the many benefits below:

Benefits:

  1. Energy savings: LEDs are far more energy efficient. A 3W LED bulb will produce the same amount of light as a 20W Halogen and a 15W CFL bulb. LEDs save 80% more energy than Halogens, and 60% more than CFLs.
  1. Longer Lifetime: On average, LEDs last for 50,000 hours. Compare that to CFLs which last 10,000 hours and Halogens which last 1,000 hours. You'll save the time and money required for maintenance and replacements.
  1. Less Heat: Unlike LEDs, Halogen and Incandescent lights produce a significant amount of heat. An average Halogen bulb can reach temperatures up to 500°C, which can easily start a fire and cause a nasty burn when touched. The heat produced also forces your cooling system to work harder to compensate, consequently increasing your energy costs. LEDs produce very little heat and do not add to an environment's temperature.
  1. Various Colour and Control Options: LEDs have a wide colour range while Halogens can only produce various temperatures of white light. LEDs can also be controlled using a range of lighting protocols such as DALI, DMX512, and 0-10V. This offers control flexibility and smart control options.
  1. Fast Switching: LEDs can withstand frequent on and off switching, whereas Halogen bulbs wear out quickly by the action. LEDs also have an instant 'ON' time whereas some CFLs operate off of a delayed start and can take up to three minutes to reach full light output.
  1. Robust, Environmentally Friendly & Safe: LEDs can withstand a greater intensity of vibration and shock, making them very robust. Furthermore, unlike CFLs, they do not contain mercury gasses or emit harmful UV rays. This makes them environmentally friendly as well as safer for users. Most LEDs operate on low voltage which is much safer to handle during installation and maintenance.

When compared with Halogen and CFL lights, LEDs come out on top in almost every aspect. So the real question should be, why aren't you using LED?
