Energy Saving

Commercial LED Lighting

If you’re adopting renewable technologies and generating and storing your own electricity, it’s important to realise you can significantly improve its performance. Especially if you install the most efficient and long-lasting commercial LED lighting – it’ll help your profits significantly.

Of course, large-scale commercial LED lighting projects are something IU Energy has a great deal of experience in.

Improve your EPC and maintenance costs

A point often overlooked is that energy efficient lighting also impacts your Energy Performance Certificate (EPC). In particular this is beneficial for Landlords, where it helps to achieve a higher rating. This is significant because Landlords can no longer rent out unless the property has an EPC rating of E or higher. 

Another key point is lower maintenance costs, which is relevant where lights are difficult to reach. Equally they are of benefit where you may have to shut down a production line to replace a light source.

To be sure, many hotels going green are taking advantage of the ease of replacing their illumination. Certainly, commercial LED lighting is an early step in the right direction. For this reason, retailers, manufacturers and countless other businesses are doing the same.

  • Place of worship
  • Restaurant
  • Retail premises
  • Sports ground
  • Warehouse

In particular, Education qualifies for Salix finance, which IU Energy will help you apply for.

FAQs

The more lumens, the brighter the light. LED bulbs require much less wattage to produce useful lumens than their predecessor compact fluorescent lamps (CFLs), halogen, or incandescent light bulbs, which is why LED bulbs are more energy-efficient and long lasting than the other types of bulb.

There are two key terms pertaining to light bulbs: watts and lumens. A watt refers to the amount of energy required to power a bulb. With incandescent bulbs, the number of watts became synonymous with the level of brightness, even though a watt really does not tell you anything more than the amount of power necessary to light the bulb.

Lumens, on the other hand, indicate the actual amount of light emitted by the bulb. For example, the technologies that have been replaced by LEDs saw a typical incandescent 40W light bulb drawing 40 watts of power and providing about 400 lumens of brightness. A compact fluorescent lamp (CFL) required 9-13 watts to produce 400 lumens, but an LED light bulb uses just 6-7 watts to provide the same number.

LEDs are the most efficient form of lighting in all applications, which is why they have superseded their counterparts.

LEDs do not emit as much heat as other sources of light: that’s because they are so energy efficient. However, LED fixtures still need to be designed to dissipate heat; otherwise they will fail prematurely.

Fluorescent lights require a high voltage burst to get started and then something to regulate the power that comes to the tube — the ‘ballast’ takes care of all of this. These ‘ballasts’ in your fluorescent fittings will ruin most new LED bulbs. Some LED bulb manufacturers offer bulbs that can work with the ballast in place, but they are less efficient and more expensive.
