All you need to know about led lighting

The popularity of LED lighting technology has grown rapidly and steadily over the years. The benefits of using
LED light fixtures over the traditional technologies have seen more and more households and
commercial buildings use them to light their indoor spaces. The LED (Light Emitting Diode) is a
semi- conductor device that converts electricity into light. LED lights use about 50% less electricity
than traditional incandescent, fluorescent and halogen options, resulting in significant energy cost
savings, especially for offices which keep the lights on for extended periods.

LED lights have a longer lifespan. Where a quality LED has a lifespan of between 30,000 to 50,000
hours, a typical incandescent bulb lasts only about 1,000 hours while a comparable fluorescent lasts
8,000 to 10,000 hours. What’s more, LED lights have directional lighting capabilities which means
that they aim light in a specific direction unlike conventional bulbs which emit light, and heat, in all
directions. Another benefit of LED lights is that the user is able to control their brightness. Some
LEDs can be dimmed according to the preference of the user. Given the above benefits, what are the
things to look out for when investing in LED lights to light your home and offices?

Quality of light

You are accustomed to measuring brightness in terms of wattage. With LED lighting, it is important
to check the lumen per watt (lm/W) of a LED light fixture while buying it. Lumens per watt measure
the energy efficiency of an LED light fixture. LEDS that produce cool white have an efficacy of 130
lm/W and the warm white have an efficacy of 107 lm/W. This is much higher as compared to the
incandescent bulb that produces just 15 lm/W and the fluorescent lamp with 60 -70 lm/W

Colour Temperature

While incandescents provide a warm, yellowish hue, LEDs come in a wide range of colours. LED
bulbs are capable of displaying a spectacular colour range from purple to red to a wide spectrum of
whites and yellows. Most people prefer colours that are similar to what the incandescent produce.
Warm white produce a golden and yellow hue like a burning candle while cool white appears almost
blue. If you are looking for a modern look for an office then cool white is the ideal colour. Bright
white produces a white light similar to daylight and is mostly used in retail stores. Colour temperature
is measured in Kelvins. The lower the number, the warmer (yellower) the light. The typical
incandescent is between 2,700 and 3,500k.

Lighting direction

LEDs are known for giving off light in one direction which makes them a good choice for overheard
lights. There are new designs which give omni-directional light which means they can be used like a
table lamp for instance.

Price of the LED light

Like all things, prices of the LED lights vary. Led panel light can cost as low as £6.99 pounds
to a high of £74.99. With this price range, you can be able to choose which one makes the most
pocket sense to you.

Dimming

LEDs are not always compatible with traditional dimming switches. Sometimes you need to find LED
bulbs which are compatible with traditional dimmers or replace your current dimming switch with a

LED compatible dimmer. It is important to find out what kind of dimming switch you have when
shopping for LEDs.

Shape

LEDs come in a number of shapes. There are spiral bulbs, different types of globes, spotlights,
floodlights and some shaped like candle flames. Choose a shape that is appropriate to your home or
office fixtures.

Now that you more knowledgeable about all things LED’s, go change your inefficient lighting (both residential and commercial) to save money and do some good to planet earth and future generations. Cheers!!
