The Car Park illustration below shows very clearly the huge savings by swapping from the standard 40watt lamp to 18 watt LED. This car park has 900 incandescent 4 foot tubes which are on 24/7. Most last maximum one year, some last no more than 6 months. When we did the survey 30 % had blown and had yet to be changed.

The key to switching to LED lighting is reduced power consumption. With correct design, an LED circuit will realise approximately 80% efficiency, in a nutshell this means 80% of the electrical energy is converted to light energy. The remaining 20% is lost through heat energy. When you compare this with incandescent lamps which operate at about 20% efficiency with a staggering 80% of the electrical energy being lost as heat.  Furthermore, LED do not cause heat build-up, producing only 3.4btu’s per hour, compared to up to 88btu’s for incandescent.

If we translate LED vs. incandescent in to a financial example, a 100 Watt incandescent is used for 12 months, with electrical cost at 33fils/kilowatt per hour, in total AED 290 will be spent on electricity costs. Out of that AED290 cost, used to heat the room, not lighting the room. The same example for LED with 80% efficiency being used, the electricity cost would be AED 44  per 12 months – This would give a saving of AED 246  over the 12 months.

The true savings are actually much higher, when you take into account that traditional lamps need to be replaced more frequently, usually within a year, and this involves man power and maintenance costs. Added to the time element that an area will not be lit due to contractual obligations. For example, many buildings do not allow repairs to be carried out when public areas are open so maintenance carried out in limited quiet period or closed period.

FM managers need to be looking at the bigger picture when analysing the true cost of energy saving with LED, the obvious figures start with the lights themselves but take that further and calculate the saving for the Cooling and Chilling Systems installed, with LED less heat is generated which naturally results in less power having to work the cooling appliances.
Companies have a responsibility to reduce their energy consumption and carbon footprint. This can be achieved in various ways but RWN promotes LED lighting as a start. By taking minor steps such as swapping from traditional incandescent to LED up to 80% of your light energy costs could be saved.

The operational life of white LED lamps is 50,000 hours. This is 10 + years of continuous operation, or 20 years of 50% operation. The long operational life of an LED lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. The long life span of the LED has naturally a direct impact on maintenance requirement. 
With incandescent bulbs, the true cost of the bulb is in the cost of replacement, the labor expense and time needed to replace them. These are important factors when considering an average office, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED lighting option.

Light emitting diodes (LED’s) are the efficient lighting solution for today’s energy issues. The future of lighting will soon see a wide spread adoption and use of white energy efficient LED light bulbs.  LEDs are available as small solid light bulbs or in cluster form with diffuser lenses which are ideal for the home environment. These cluster beams can use as many as 180 bulbs per cluster and the light is spread evenly.  Quite recent to the market are dimmable LED which offer extra saving as when they are dimmed to the zero position they emit no energy unlike their traditional counterpart that still emits energy loss at zero. 

At present the draw back to switching to LED has been the initial cost but the efficiency and cost effectiveness of LED lighting systems will drive demand for more affordable LED lights. Irrespective of cost there are still tremendous financial and energy savings to be achieved.

The need to switch to sustainable energy solutions is never more so

 an issue than for UAE as demand out strips demand on a regular

basis. Lighting represents 22% of electricity usage in the Middle

East and this is a much higher statistic than anywhere else in the

world. If GCC consumers switch their homes to more efficient

solutions this will save up to US$ 400 million and 5.1 megatons

 in carbon dioxide emissions annually. By switching to LED lighting

 solutions this is a first step to be making a difference.
