What Are The Considerations For Purchasing LED Bulbs?

29 October 2019 by

LEDs are all set to transform the lighting ideas of this century. It requires familiarity with new terminology and considers the new facts usually absent while preparing a lighting design. This article gives you an idea of the considerations to buy LEDs.

LEDs are semiconductors producing light more efficiently than traditional modes of light sources. When electricity is passed through them, they emit light. Doping them with chemicals produce light of different wavelengths. They convert most of the energy passed into the light without heating up, thus saving the energy spent as heat. It is 90% more efficient than traditional lights.

LEDs have been widely used as displays and indicators for as nearly as 40 years. The recent innovation of finding its use for general purpose lighting has helped engineers figure out the mass production of bright, white LEDs. LEDs come with high brightness and point-source characteristics making them the first choice for traffic lights and car tail lights giving visibility and dependability.

Checklist to find the LED best suited for you.

Take into account the following factors that help you choose LED over traditional lights:

  1. Though the initial cost is high, the total lifetime cost is lower than the traditional counterparts. Taking into account the time and resources to replace CFLs, LEDs last 80,000 hours with much lower lifetime cost.
  2. The LEDs apt for your requirement is a difficult way to find. The CRI of 85 % is the ability of light to produce colors of various objects in comparison to natural lighting. They last much longer than novelty bulbs as well as 60% longer than those that use inferior LEDs.
  3. LEDs do produce heat, that many manufacturers face as a hurdle. They have successfully developed LED lighting applications with chips as bright as 100-watt incandescent bulbs that find ventilation problems while installation in fixtures. The better the chip, the more it has to be ventilated. Or else it can fail prematurely.
  4. The lifetime of LEDs will have to be carefully looked at. The life span is usually its half-life. As they do not burn out, rather fade out, when it is said to have 80,000 hours, they mean that the chips will have reached 50% o its efficiency. So even if the bulb lasts for 100,000 hours, its efficiency will be heavily degraded. Even though the facts are against it, LEDs last 50-75 times longer than incandescent and 6-8 times longer than CFLs.
  5. You can find that the LED market has products at different rates. A good quality LED will cost more than the inferior one. So it is important to find the best product that may cost even higher. The expensive ones are superior.
  6. LED lights are difficult to be dimmed. Instead of traditional dimmers, a 0-10v dimming module is required to dim the LED. All LEDs are dimmable with this module without flickering or turning useless.
  7. Lumens is the standard unit to compare LED light bulbs to standard bulbs, incandescent or halogens. Lumen quality is more important than quantity. Lumen efficacy between 60-70 lumens/watt is the standard for every LED. 
  8. Color temperature and beam spread are important in figuring out LED efficiency. 3000 Kelvin is warm white, 5000 Kelvin is cool white. The natural color of LED is cool white and the warm white is produced due to the phosphorous filter added to warm the color temperature. Beam spread is the angle of the light emitted by the LED. The lower the angle, the light becomes more like a spot.

While there are many factors on which the LED lights depend on to give you a bright interior, these are some that can come handy for you.
