The high-temperature LED high-bay luminaire is the ideal solution for industrial areas with elevated ambient temperatures up to +70 degrees Celsius and ceiling heights reaching 30 meters. With three powerful output levels ranging from 400 to 600 watts, it provides precise and reliable lighting for large-scale industrial environments. The luminaire incorporates collimator optics in linear technology with three practical symmetrical beam angles of 30, 60, and 90 degrees, which effectively reduce stray light and direct the light exactly where it is needed. Its modular design ensures easy maintenance and adaptability, while DALI-2 dimming comes standard to enable flexible lighting control. A generously dimensioned heat sink supports thermal management, ensuring stable operation even in high-temperature conditions. A five-year full warranty and a ten-year spare parts guarantee make it a secure and long-term investment for industrial operations.
The luminaire features two constant current power supplies with integrated DALI-2 dimming and optional constant lumen output (CLO), or an optional high-voltage version for specific applications. Its modular structure allows exchangeable and replaceable main components, ensuring long-term serviceability. The die-cast aluminum heat sink is dust-permeable and highly effective, while a pressure compensation membrane prevents condensation. The housing is solid and optimized for operation in high-temperature environments up to +70 degrees Celsius. The optical system is impact- and UV-resistant, employing linear technology to reduce stray light across three beam angles.
The lighting properties include an initial luminous flux range of 66,000 to 99,000 lumens, with a tolerance of ±10 percent, and an initial system efficiency of up to 165 lumens per watt. The most similar color temperatures are 4,000 and 5,000 kelvins, with a color rendering index (CRI) above 80 and color consistency of less than 5 SDCM. The luminaire provides photobiological safety according to IEC/TR 62778, with a compact flicker degree of just 1 percent.
Electrotechnical properties include AC power supply of 90 to 240 volts and DC power supply from 140 to 250 volts, with two integrated power supplies. System performance ranges from 400 to 600 watts with a tolerance of ±10 percent and a power factor greater than 0.90. Overvoltage and overheating protection, along with temperature monitoring, ensure reliable operation. Total harmonic distortion remains below 20 percent, and the luminaire has an ATEX temperature classification of T5 with a Tc temperature of +89 degrees Celsius.
The luminaire holds energy efficiency class C for all models. Standard mounting options include a ceiling bracket with an adjustment range of –45 to +45 degrees, while optional wall brackets provide a 0 to 90-degree adjustment range. Control and safety options include DALI-2 dimming with a minimum dimming level of 10 percent, optional constant lumen output, and Casambi network integration. Emergency light modules, human-centric lighting, and daylight control via the Casambi network are available upon request.
The housing is rated for ambient temperatures from –40 to +70 degrees Celsius, with IP65 ingress protection and IK08 impact resistance. Electrical protection class is I, and the limited surface temperature ensures safe operation. The luminaire and heat sink are constructed from die-cast aluminum, with a ceiling bracket in stainless steel powder-coated in white aluminum according to RAL 9006. The optical system is impact- and UV-resistant polycarbonate, and the cover plate is 5 mm toughened safety glass. The luminaire housing is white aluminum, and the power supply housing is water blue according to RAL 5021. The surface finish is powder coating, and the supply cable is H05SS-F 5G1 at 250 centimeters, with plug connector inlet and open cable end connection. The luminaire operates on a 3-grid / 2 DALI pole configuration.
Additional information includes certificates in preparation for ENEC, CE and RoHS conformity, and lifespans of approximately 100,000 hours at 25 or 70 degrees Celsius (L70B10C1) and 50,000 hours at 25 degrees Celsius (L90B10C1). The luminaire is supplied with a ceiling bracket and fall protection, with the mounting eyelet included where applicable.
Accessories expand functionality and installation options. Wall brackets allow surface mounting with a 0 to 90-degree adjustment range. A 3-pin safety plug with IP44 ingress protection is installed on the supply cable. Ready-to-use 5-pin supply cable extensions up to 10 meters are available, along with Wieland RST 20i5 5-pin connectors and sockets with turquoise blue coding for 250 V and 20 A. A Casambi control unit enables network integration and control at ambient temperatures up to +50 degrees Celsius. Emergency light modules automatically detect failures and restore power, providing a runtime of approximately 1 hour at 6 watts or 3 hours at 3 watts, with a recharge time of 24 hours. These modules are also suitable for use at ambient temperatures up to +50 degrees Celsius and are mounted directly on the luminaire.
