PROJECT FOCUS

PROJECT FOCUS

All fixtures were required to provide easy and safe access for maintenance purposes , so that the installation can be kept in full working order with minimal disruptions , costs and no danger to staff .
Emergency lighting had to follow safety recommendations from relevant sports governing bodies , whilst user friendly and accurate dimming functions were also essential to allow staff to easily adjust light levels and distributions for different activities .
An attractive modern aesthetic was to be maintained throughout the premises to appeal to the public and match the stateof-the-art equipment and facilities provided by the centre .
Steve Howe , specification manager for Dextra Lighting who looked after the project , comments , ‘ The main criteria for the project was quality of product , high efficiencies and service from design right through to the install via the contractor on site . Dextra Lighting ticked all the boxes and it made our offer favourable to the client .
‘ Several unique tweaks were needed to our standard product offering in order to meet the controls specification on the project . Our JIT facility and quick responses enabled us to offer flexibility and great service to help the customer .’
Sports hall
With ceiling heights of over 8m and narrow windows , the sports hall relies on powerful artificial lighting to support a range of sports , such as five-a-side , badminton , rollerskating parties , basketball and netball . To deliver maximum power , flexibility and energy efficiency , the Prosport LED was installed in a high output version of 34,500lm from a range of lumen packages , with DALI dimming controls to provide adjustable lighting up to the recommended maximum of 500lx for sport halls . At this output , luminaires could be configured using the most efficient spacings , to provide optimal vertical illuminance and uniform coverage , giving players maximum visibility of fast moving objects such as balls or shuttlecocks .
The Propsort LED ’ s optics are designed to boost the efficiency of its high quality Lumileds LED source offering LORs of over 80 per cent and an overall efficiency of 140Ll / w . The two part system consists of curved clear polycarbonate diffusers and an LED shield to provide a broad , bright , yet controlled distribution of light .
The luminaire was supplied with a versatile symmetrical optic to provide an ideal light distribution for sports such as football , basketball and netball . An optional asymmetric bracket is also available with this range , providing angled lighting for court lighting , eliminating disturbing glare when players look upwards .
The Prosport is engineered to provide durability , protection and aesthetic appeal to modern sporting venues . Its robust steel housing , reinforced injection moulded polycarbonate end caps and diffusers provide suitable protection from ball strikes , whilst its angled design minimises the risks of projectiles being trapped at the rear of the luminaire . Unlike HID or fluorescent alternatives , the absence of fragile lamps eliminates the risk of shattered lamps on impact .
By combining energy efficiency , low maintenance and quick installation , the Prosport LED has guaranteed a fast and
substantial return on investment for Allerdale council .
Due the multifunctional purpose of the hall , luminaries could be easily and immediately programmed at different settings via the user friendly RE-AP remote control from ground level , to suit each sport or event .
Fitness studios
The ModLED Slim recessed luminaire was used in studios with lower level suspended T ceiling systems and was supplied in a 4,500 lumen package designed specifically for new build applications , to minimise energy consumption and capital cost of installation by providing maximum luminaire spacings .
The luminaire uses a high transmission polycarbonate diffuser panel offering 93 per cent transmission of its Lumileds LED source , LORs of 85 per cent and increased visual comfort .
The ModLED Slim provided the recommended 400lx for high intensity and often supervised workout sessions in the weightlifting gym without compromising on visual comfort . A lower 300lx was required in the other areas , such as the cycle studio and practice hall used for a variety of fitness classes .
The lighting had to ensure that all sports and activities could be performed safely with maximum visibility and comfort .
The sports hall relies on powerful artificial lighting to support a range of sports .
More directional downlighting was provided in the larger 90-station gym studio , featuring treadmills and crosstrainers , with the attractive and efficient Discalo LED architectural downlight providing localised lighting at an average of 300lx from above each workout station .
The selected luminaires offer an appealing minimalist design that harmonised successfully with the centre ’ s modern interior design , and all lighting was provided with ‘ cool white ’ 4,000k LED sources to help maintain a fresh and vibrant workout environment for users .
Emergency lighting
In all locations , over half the luminaires were supplied with integral auto-test emergency lighting , which allows the entire network luminaires to be monitored automatically via a DALI operated system . Maintenance staff will be able to receive periodic reports of any faults via a user friendly digital interface . The practical system will help ensure the installation is kept fully functional and safe at all times whilst avoiding the costs of calling specialised technicians to perform tests . To support the integral emergency functions of these luminaires , the highly efficient and durable Highspot LED emergency luminaire was installed in strategic locations . Its 500lm output is intended for high level applications or where very wide spacings must be achieved , such as the sports hall and the main pool area . Available in three lens types , the luminaire was supplied in both an Open Area and Ultra High Rack version , to optimise the light distribution to each location . The Highspot LED was also linked to the auto-test system .
Mark Wilkinson , lighting design services , Edmundson Electrical , Carlisle , concludes , ‘ We have used Dextra Lighting on numerous projects and yet again they have provided us with a total service and quality product with high efficiencies . All are delighted with the finished project at Workington Leisure .’
An attractive modern aesthetic was to be maintained throughout the premises .
