The Cheadle and Marple College Network is formed by a partnership of two firmly established sixth form colleges serving the Stockport area for over fifty years. The colleges have a combined student population of approximately 2000 between the ages 16 and 19.
Described by OFSTED as having “a dynamic and relentless culture of improvement”, the college network recently launched a multi-million pound redevelopment programme to improve its estate, involving both the construction of brand-new learning spaces and refurbishment of existing facilities.
As part of its pledge to better serve the community, the plan was aimed not only at offering a state-of-the-art learning environment for its students but to ensure that both its Buxton Lane and Marple campuses would serve as examples of sustainable practice.
In partnership with appointed consultants DDA and electrical installers, Performance Electricals of Stockport, Dextra Lighting was chosen over competitors to collaborate in the project as the sole lighting provider due to its vast manufacturing capabilities, flexible and fast lead and delivery times, comprehensive range of energy-saving LED products and controls and its extensive portfolio of success in the education sector.
LED lighting is now widely acknowledged as the most immediate and effective measure to upgrade educational facilities whilst making them cheaper and greener to run. Compared to conventional lighting, high-quality LED systems offer a number of benefits that allow institutions to aim higher in the provision of better education by unlocking financial opportunities previously unavailable Gxg game download.
Energy-efficiency is the primary advantage of converting to LED. As electricity is more expensive than any fossil fuel used to power a building, lighting amounts to an average of 20% of a typical college’s utility bill when it only represents 8% of actual energy usage. This gap between energy use and cost makes lighting a key area to focus on when trying to implement a sustainable management framework. With this in mind, LED solutions can offer average savings of 60% over HID and fluorescent lighting with sensor controls (daylight regulation and occupancy detection) reducing energy consumption further by a potential 30% depending on the application.
The majority Dextra Group luminaires are manufactured with the latest LM80-verified 3535 Lumileds LED offering 90% lumen maintenance for the first 60,000 hours of operation. In contrast to HID or fluorescent sources, these high-quality sources keep their intended brightness for longer and are more durable to physical stresses in the environment, allowing installations to cut maintenance costs by avoiding frequent lamp changes. By using only the best European-made drivers, Dextra Lighting solutions offer added reliability and require less servicing and repairs throughout the products’ lifetime.
The combined energy and maintenance savings offered by LED usually allow the initial cost of a typical installation to be quickly paid back and will continue to free up capital to be invested in other areas of service in the long-term music in December.
Unlike fluorescent lamps, LED sources do not contain hazardous or toxic materials such as mercury, which pose potential health risks if broken on site, or to the environment upon disposal. Replacing damaged LED fixtures on the other hand, is a quick and simple process which does not require extra precautions and will be less damaging to the environment once it reaches the end of its lifetime.
Most of Dextra Lighting’s LED products designed with the educational sector in mind, are included in the government’s Energy Technology List (ETL); offering institutions eligibility to the Enhanced Capital Allowance (ECS) scheme for 100% tax levy for the first year of purchasing the equipment. By reducing their carbon footprint, schools and colleges can gain access to funding reserved for environmentally conscious renovation projects, and improve their performance on the Carbon Reduction Commitment table for further financial benefits.
Finally, recent developments in LED technology have allowed systems to offer increased light quality to improve student performance. Research has strongly shown that LED systems, which are tuneable to mimic natural light more effectively and offer higher colour rendition and uniformity of light than conventional lighting, help create a more stimulating and productive learning environment for students and teachers alike as they can be aligned to the occupants’ circadian rhythm throughout the day. Overall, using LED systems with intelligent controls has been closely correlated to higher concentration and task focus amongst pupils.

Prosport LED / Arcus LED – Sports Hall & Gym
Specifically developed for modern sports environments, the Prosport LED utilises high-performance LED sources and optics to optimise lighting conditions for a range of indoor sports whilst keeping energy and maintenance costs to a minimum latest version of Lucky Patcher. The versatile luminaire offers a choice of distributions and output packages as high as 30,601llm across two different sizes, ensuring that the recommended lux levels, uniformity ratios and glare control are tailored to each sporting activity. By ensuring a superior quality of light, the luminaire can maximise visibility of fast moving objects in the field of play to increase safety and improve player experience overall.
For the sports hall, a 21,288llm version of the luminaire amply achieved lux levels within the 500 to 750 parameter recommended by Sport’s England for recreational or school use, whilst economising on the amount of luminaires used. A standard, yet versatile, symmetrical optic was specified to support a wider range of sports including football, basketball and netball. For badminton or tennis applications however, an asymmetrical bracket can be supplied for an angled, glare-free distribution which also avoids balls and shuttlecocks to become lodged behind the luminaire. With no natural light entering the hall, luminaries were also carefully positioned to make the most of wall reflectances, avoid glare and spaced as widely as possible to achieve a bright and even coverage with fewer fittings.
The Prosport LED’s robust steel housing and polycarbonate end caps offer suitable protection from ball strikes, and unlike fluorescent or HID luminaires, its LED source eliminates the risk of shattered lamps 유로파 리포트 다운로드. This durable construction combined with the long life and low-maintenance benefits of reliable Lumileds LED chips, makes the Prosport LED a hassle-free and sustainable solution for high-level sports environments.
For a cost-effective installation, the Prosport was supplied with a zintec spine to simplify mounting at inconveniently high ceilings and was prewired to the required specifications. This helped accelerate the fitting process, avoiding prolonged disruptions to the normal functioning of the hall.
With a choice of DALI or Analogue 1 – 10v dimming options, the luminaire offers the flexibility to adjust light levels for different sports as well as generate further savings with a choice of sensors from Dexsor’s Reacta range.
