Place Grand Synthe
A visit to ETAPs light pavilion in Malle convinced the management of the Lycée professionnel de lautomobile et du transport in Grande-Synthe of the importance of energy-efficient LED lighting that features a long service life. After renovations at the Lycée professionnel de lautomobile et du transport in Grande-Synthe they will be assured of their lighting installation for 20 years.
The lighting installation at the Lycée professionnel de lautomobile et du transport in Grande-Synthe (northern France) urgently needed replacement. Lighting levels were insufficient and it had become increasingly difficult to service the obsolete fluorescent luminaires with ferromagnetic ballasts. A visit to ETAPs light pavilion in Malle convinced the management of the Regional Council Nord Pas de Calais Picardie, responsible for the schools infrastructure, of the benefits of sustainable LED lighting. The high maintenance factor of ETAPs LED luminaires was particularly revealing. The combination of high quality LEDs and sophisticated luminaire design results in high lumen maintenance in the long term. Sustainability guarantee "ETAP makes an LLMF (Lamp Lumen Maintenance Factor) available for all its LED luminaires after 50,000 hours," states project manager Pascal Morin. "For schools, a high LLMF implies the certainty that the lighting in classrooms and corridors satisfies the EN12464-1 standard for at least 20 years. This sustainability guarantee was conclusive for the Lycée in the decision-making process." In the practical training rooms they opted for the E4: an industrial LED luminaire with high specific luminous flux and very precise light distribution (thanks to DUAL-LENS technology). Due to the many skylights in the roofs, there is an abundance of daylight: therefore it was obvious that the majority of luminaires were fitted with an ELS daylight sensor. The lighting installation in the theory rooms is an LED+LENS solution, i.e., a combination of U7 and recessed luminaires with wide-angle light distribution and R7 surface-mounted luminaires with asymmetric light distribution for blackboard lighting. Here too, daylight-dependent light control results in additional energy savings. Project data - 460 E4 luminaires - 100 recessed U7 luminaires - 20 suspended R7 luminaires
