MAXIMISING LED BENEFITS
Maximising the benefits of LED lighting requires not just high-quality light sources but also
luminaires designed to take advantage of the characteristics of those light sources. Lewden’s new MITO Led luminaires do just that, with a wide range to suit many applications
T
he benefits of LED lighting have now been understood for several years, in
terms of energy and other lifecycle cost savings, as well as reduced carbon emissions and environmental impact. Much of the focus, however, has been on the light source itself, with less emphasis on the key role played by the luminaire. LED light sources differ in a number of
ways from more traditional light sources, so it is clearly important that these differences are reflected in the design of the luminaire. Equally, lit spaces can vary widely in their configuration and lighting requirements. Selecting the right luminaire is therefore essential when it comes to maximising the benefits of LED lighting. Lewden, for example, offer the MITO Led range of luminaires, which has been specifically designed to meet the requirements of a range of applications, including industrial, warehousing, indoor sport, retail and food production areas – as well as outside areas. In each case, the design of the luminaire ensures that the performance of the LED light sources is exploited to its full potential. MITO Led luminaires feature a circular geometry that ensures visual comfort while avoiding the need to orientate the luminaire to achieve the ‘right’ lighting. They also deliver a long life, maintaining more than 80 per cent of their original luminous flux after 50,000 operating hours. Optimum performance is enhanced by the die-cast aluminium body, which acts as a highly efficient helical heat sink.

MITO Led is easy to install, optimises energy cost saving and keeps installation costs to a minimum
SOLUTIONS FOR ALL APPLICATIONS The wide range of configurations ensures that MITO luminaires can be selected for a wide range of new and retrofit applications. For example, mounting options include pendant suspension, double chain suspension, adjustable suspension, ceiling mounting, horizontal pole mounting, adjustable brackets and catenary wire mounting. The pendant suspension fixing makes replacement of traditional high bay luminaires a simple ‘remove and replace’ operation, without the need for adaptation and regulation. Replacing an old high intensity discharge (HID) fixture with MITO Led guarantees a range of benefits, including energy savings of up to 50 per cent, zero maintenance costs, comfort and health protection (no mercury), clean light with no degradation of plastic components (no UV and IR), and flexibility through a range of light distribution options.
LIGHT DISTRIBUTION OPTIONS MITO Led luminaires with symmetrical 100°(wide) light distribution are suitable for buildings between five and 9m high, while for heights above 9m a narrow (60°) symmetrical light distribution will often provide the best solution. For applications such as warehouse aisles, MITO Led luminaires with elliptical light distribution ensure the light is directed precisely to where it is needed. For sports centres and external areas there are also options with asymmetrical and roadway light distribution respectively. For food industry applications, MITO high bay fittings with a polycarbonate diffuser, and choice of symmetrical or elliptical light distribution, are available. All versions of MITO LED can be equipped with an emergency lighting module, with the inverter and battery pack mounted
on the back of the fixture using a purpose-made bracket. If preferred, the inverter and battery pack can be located remotely from the fixture.
SMART CONTROLS The MITO Led smart management system makes it compatible with all types of smart control systems. Using either stand-alone or centralised detection and control systems, MITO Led offers modularity and compatibility, whilst use of wireless technology ensures the system is easy to programme and manage. The MITO Led range is equipped with 1-10V dimmable control gear, DALI or other wireless systems if required.
ENERGY SAVINGS Exact energy savings will vary from one project to another, depending on the previous lighting, hours of use and layout of the space. However, a good illustration of achievable energy savings is provided by comparing a MITO Led installation with an HID installation, with an assumed energy cost of 11p/kWh. For this comparison, assume the
original installation has 100 x 400W fixtures, which are replaced on a one- for-one basis with 171W MITO Led fittings. In an industrial application working two shifts, amounting to 4,000hrs of lighting usage per annum, there will be a power saving of 103,600kWh – amounting to a financial saving in energy costs of £11,396. There will also be additional savings from improved control and re-lamping and other maintenance costs. The new MITO Led range joins Lewden’s
family of LED solutions for industrial and other applications, including Atex, tunnel and marine projects.
