LED Lighting
Are you aware of the savings that can be made by upgrading your existing lighting to LEDs. LED lighting is a must for your lighting needs, Over a period of time the energy savings made on power consumption will pay for the installation and also cut down on your maintenance as the average lifespan of an LED lamp is 20 times that of a standard lamp.

LED UPGRADE SAVINGS EXAMPLE
An office currently runs standard fluorescent strip lights (1500mm T8 tubes) throughout, with over 60 lamps across 3 floors. The owners are considering upgrading all the lights to LEDs, in order to save power and to make them compatible with an office automation system (to turn them on and off automatically).
So, how much energy could they save?
Well a standard fluorescent lamp consumes about 58W, whereas the new LED lamps consume around 20W. Therefore over the course of a year we would anticipate the energy savings to be as follows:
|
|
Standard Fluorescent lamp |
LED lamp |
|
Power Consumption |
58 Watts |
20 Watts |
|
Hours in use |
10 hours per day, 5 days a week, 52 per year |
10 hours per day, 5 days a week, 52 per year |

Hours per year |

Kilowatt hours per year (watts / 1000 * hours) |
150.80 kWh |
52 kWh |
|
Cost per year (at 10p per kWh) |
£15.08 |
£5.20 |
Therefore multiplied by 60:
Standard lamp - £904.80 per year.
LED lamp - £312.00 per year.
