After more than two decades of producing the energy efficient optical system for commercial outdoor lighting, Schréder Lighting USA highlights the innovative, award-winning Sealsafe Optical Lighting System in the United States. Sealsafe street luminaires deliver higher levels of light while minimizing light pollution, energy and maintenance costs, and reducing levels of crime and vandalism. Schréder Lighting USA, the newest of the 40-member Schréder Group G.I.E. located in 36 countries on four continents, is marketing the Schréder brand for Public Lighting, Floodlighting, Tunnel/Transit Lighting, Industrial and Urban Lighting.
Schréder’s famous Sealsafe system has significantly impacted society as a revolutionary lighting and lifestyle philosophy, becoming apparent in current street lighting practice and standards. The robust construction of Sealsafe has dramatically reduced vandalism and other crimes, resulting in significantly lower maintenance and energy costs for local authorities. The high level of optical efficiency of Schréder reflectors reduces the number of fixtures needed to illuminate any area.
Granted "Queen's Award for Enterprise: Innovation" several years ago in the United Kingdom, Sealsafe continues to prevent dust and water ingress to IP66 standards after 22 years, according to independent SI tests in Wandsworth Borough where the firm's ZX1 luminaires are still performing to standard.
Sealsafe ensures lifetime protection with a hermetically sealed optical unit, crafted of 99.9 percent cast aluminum designed with a reflector bonded to its lens, and engineered with “Breathing Seal Technology.” When the lamp switches on, air expands and exhausts from the sealed optic compartment eliminating stress on bonded surfaces. When the lamp switches off, air cools, a vacuum is created and outside air pressure pushes seal against smooth interior surface to restrict inrush of air and dirt.
Maintenance professionals access the lamp easily by removing a quarter-turn lampholder support featuring a unique Lip Gasket (pictured), which creates a waterproof, dustproof enclosure. The Sealsafe optical unit is enclosed inside the luminaire, creating a “double envelope.” Sealsafe’s unique design enhances luminaire performance and eliminates internal cleaning of the reflector while granting IP66 tightness level for many years.
Backed by Schréder’s 20-year warranty for tightness, Sealsafe is widely used in Schréder’s products and provides many reflector sizes and designs, enabling designers to use the latest lamp technology, including white light CDM-T and new Cosmopolis lamp. The Right Lighting is achieved with optimal tubular “point source” lamp positioning inside the optical unit while illuminating the installation’s parameters, and spreading a higher light flux is on the ground without lighting pollution.
