LED (Light-emitting diode) bulbs are commonly used for lighting due to their impressive lifespan and cost-effectiveness compared to incandescent bulbs. They are also more environmentally friendly and energy saving than conventional bulbs. Manufacturers have made great advancement in the manufacture of LED light bulbs over the years by making it possible to produce white LED light using a single semi-conductor chip as opposed to prior years where the same could only be produced through mixing three different chips. This has led to greater efficiency and reduced cost of these bulbs. When choosing an LED light, there are various things that you need to consider. These include the following.

Features of LED light bulbs

When buying LED light bulbs, there are various terms that one is accustomed to that are used to define the efficiency and performance of the bulb. It is important to understand them when purchasing LED for lighting in order to get highly efficient bulbs. These include the following.

  • Watts. Watts or wattage refers to a measure of how much energy a light bulb draws, as opposed to the belief that it is the measure of brightness. With LED light bulbs, watts are not an indicator of the bulb's brightness, since they draw less energy compared to incandescent and traditional bulbs.
  • Lumen (lm). This is the measurement of the brightness produced by an LED bulb and is what you should look out for when purchasing a light bulb. A bulb with higher lumens will burn brighter; therefore, get a sense of the level of brightness you want before purchase. You can always have the bulb tested for this.

Color of light bulb

One latest feature of LEDs is that the light can be adjusted to the full spectrum of colors. Some manufacturers have designed LED bulbs that can be controlled through a smart phone allowing one to choose the desired color of light from a full palette. The color factor is an important consideration when choosing these bulbs. The color will depend on the room where it is used and the desired mood to be created. Yellow and white lights are common; however, other colors such as purple and red are also available. They range from soft to warm and bright lights.

Type of dimming switch

In some cases, LED bulbs may not be compatible with traditional dimming switches. You may need to have the switch replaced or get a compatible LED. When buying LED light bulbs, you should know the type of dimming switch you have; otherwise, get bulbs that are compatible with standard dimmers. Though a little costly, replacing switches with new LED-compatible ones is a better option that will pay off in the long run.

LED lights are increasingly becoming popular for residential and commercial lighting due to their incorporation of the latest technology with energy-efficiency, sustainability and cost-effectiveness.
