Holophane details its upgraded Metro Capabilities range, which now includes a wider selection of luminaires specially designed and engineered for rail tunnel applications.


W


hen tailoring a lighting scheme for metro applications it is key to en-


sure that the design of the lighting takes into account the special requirements of the railway environment, which can be harsh in terms of deterioration to lumi- naires and diffi cult in terms of access to maintain the equipment.


The effective maintenance of luminaries is essential to its continuing effi ciency and adherence to the requirements of specifi c rail standards. Therefore luminaires and controls systems used in a metro type envi- ronment must be straightforward to install, easy to operate and simple to maintain whilst also ensuring the maintained illumi- nance is achieved throughout the life of the luminaire(s).


Metro Capabilities


Holophane’s upgraded Metro Capabilities range includes Metrolux and Widerlite bulkhead luminaires and the Prismashield Elite multi-functional luminaire that is ide- al for use with infi ll panels.


All Metro Capabilities luminaires are fully compliant with legislation and best prac- tice relating to tunnel lighting, with excel- lent light distribution for drivers, mainte- nance crews and passengers alighting in


tunnels under emergency conditions.


Metrolux and Widerlite are available with LED or compact fl uorescent light sources, for optimum energy effi ciency, controlla- bility and long lamp life. For example, the LED versions deliver a lamp life of 60,000 hours under typical conditions, and are listed on the London Underground ap- proved supplier product list. Holophane has also launched a Metrolux and Widerlite Retrofi t LED light engine, enabling com- pact fl uorescent versions to be quickly and cost-effectively upgraded to LED lighting.


Adaptation


Both feature a prismatic glass refractor that controls light output which ensures even light distribution and minimises shadows while aiding visual adaptation. Metrolux also has a special safety mechanism that prevents the door from swinging open, a vital feature in tunnel applications.


The rugged die-cast aluminium front frame and body of Metrolux and Widerlite pro- vides the durability required for the harsh conditions in tunnels and this is combined with a number of features to facilitate quick and simple maintenance.


Stainless steel quick release door latches


allow easy access to the lamp and control gear compartment with the minimum use of tools for maintenance.


Metrolux and Widerlite are also ideal for security lighting, gantries, boiler houses, conveyor tunnels and local industrial lighting.


Robust


Prismashield Elite is a robust, stylish and multi-functional luminaire engineered to withstand severe physical attack, exposure to weather and vibration. The luminaire is available with a frosted glass lens for un- derground tunnels or a polycarbonate lens with internal prisms. Both optics produce a precise symmetric or asymmetric light distribution for even, glare-free illumina- tion - helping people feel safe and secure in arduous environments.


Prismashield Elite is a versatile lighting solution that can be surface mounted indi- vidually or in continuous runs utilising the infi ll panels system. An optional integrated surface cable management system can be attached to conceal power, emergency and communications in a complete solution.
