A guide to saving energywith LEDs


Paul Stearman, Specification Manager for Kosnic Lighting Ltdtalks us through the vast range of retrofit LED lighting products on the market, their suitable applications and how they can help achieve extraordinary energy savings of up to 90%.

e’re all aware of the importance placed on energy saving, both from an environmental and


cost-efficiency point of view and switching to LED lighting is a highly efficient way to decrease energy consumption. Alone, this can lower energy usage by between 50-90% when compared to traditional filament, fluorescent and even discharge lamps. If control devices such as occupancy sensors and light level sensors are incorporated, the savings can be even greater. The willingness to embrace LED lighting has been a little lacklustre. All industries have considered and trialled LED lighting in the past and dismissed it due to poor colour temperatures, poor light output and poor reliability, resulting in reluctant take- up. But manufacturers have addressed these issues to produce today’s products that deliver the correct amount of instantaneous light, colour rendering and temperature, as well as hugely improved reliability. Now, LED lamps can last for thousands of hours, with manufacturers offering warranties of three years or longer. But where can these LED lamps and luminaires be used? And what traditional products can they replace? Many LED lamps can be retrofitted into an existing luminaire without the need for rewiring. The most common example is the replacement for the Halogen GU10 lamp. The Halogen GU10 lamp is conventionally


between 1,000 and 2,000 hours, a Halogen GU10 lamp can be directly replaced with a retrofit 5W LED GU10 to deliver energy savings of up to 90%. Additionally, a product such as the Kosnic HaloLED will deliver the same light while lasting more than 15 times longer as it has a life expectancy of 35,000 hours. Not only does it deliver

for longer but the HaloLED – as well as Kosnic’s Pro and HiLux


GU10 products – is also available in different colour


temperatures and colour renderings, as well as in dimmable versions.


Replacing fluorescent luminaires Fluorescent luminaires are typically installed in ceilings within commercial and education facilities, with a 600mm x 600mm ceiling grid the standard size. Commercial LED luminaires


have been developed as replacements to provide more light than existing versions, reducing the number of luminaires required to maintain the appropriate lux levels. For use in offices, schools, storerooms,


corridors and transient places, the Kosnic 36W LED Panel guarantees constant light across the surface of the panel and is a really easy to fit replacement for fluorescent luminaires. Similarly, the LUMI Twin Bar and Kurve LED Modular luminaires are also perfect for these applications as well as board rooms and meeting rooms, with all the products offering a life expectancy of 40,000 hours to reduce maintenance and expenditure on replacement lamps. Similarly to the LED GU10, a range of wattages, lumen outputs and colour temperatures are available to suit a variety of settings and situations. And with the LED models consuming between 30-50W, compared to the 85W of the traditional fluorescent luminaries, energy savings of at least 60% can be achieved.
