The Benefits of LED

We can’t become rich overnight, and it’s even harder to fix the planet just as fast. However, as the advert goes, “every little helps” and it’s certainly true when it comes to LED (light-emitting diode) lighting.

It might only save you a few pounds every month, but that can add up to triple figures in just a year’s time (Evans, 2014). Installing a few LED lights might not cancel out the millions of tons of CO2 emissions that companies like Duke Energy spew into the atmosphere every year (Helman, 2013), but they could cut the emissions you produce from lighting by over 60%. So, just imagine if everyone bought LED lights.  

The benefits of LED's don’t just end there though, and whether you’re concerned with the personal impact or the environmental benefits, we think the infographic below might help convince you why we love them so much.

WHAT IS LED LIGHTING?

Light emitting diodes (LED’s) are semiconductor devides convert electricity into light. They do not depend on a filament or fluorescent tubes and are more durable.

 

WHY THE FUSS ABOUT ENERGY EFFICIENCY?

  • Energy efficiency is good for the environment.
  • Energy efficiency is increasingly making business sense, and makes for better return on investment.
  • Energy efficiency is improving global economies and creating jobs.
  • Energy efficiency has the potential to improve overall quality of life.
 

THE BENEFITS OF LED

  • LED lights use less electricity and have a longer life span, saving you money in the long-term.
  • LED lights can last up to 40 years. That’s 14,6000 days and 58,400 hours over that time period.
  • LED lights have a longer-life span, once again saving you time and money.
  • LED lights can produce bright, good quality light in any colour.
  • LED bulbs are easier to dispose of because they do not contain any hazardous material.
 

LED ENERGY SAVINGS

The average household in the UK has 27 light bulbs in it (not counting those on the cooker, in the fridge, etc), mostly halogens and CFLs. The electricity consumption is 465kWh pa, costing about £70 pa and representing 14% of the average electricity bill.

 

MEASURING LED USAGE: WATTS VERSUS LUMENS

The brightness of LED lights is measured differently to other light fittings.

LED lighting is measured in:

  • LUMENS
    • Measure a light’s actual brightness
    • By contrast, wattage is a measurement of how much electricity a bulb uses
    • The effectiveness of an LED bulb is best expressed in its lumen-to-watt ratio (the number of lumens produced for each watt consumed)
  • WATTAGE
    • Measures how much electricity a bulb draws
    • Traditionally used to measure the output of incanedescent bulbs
    • A 60w incandescent bulb is worth a 6W LED

LED VERSUS THE OTHERS

CFL bulbs were the more commonly purchased form of energy saving light until the arrival of LED.

However, CFL bulbs will generally generate more heat than LED bulbs and take longer to warm up.

LEDs are now much cheaper than CFL and other models of fluorescent bulbs.

Features:

  • CFL use up to 60-80% energy than incandescent lamps versus LED’s 90%
  • Lasts almost 10 times longer than incandescent bulbs
  • Produces less heat
  • They have a lifespan of about 10,000 hours
