The Thunder Series LED high bay lights provide many standard industrial lighting features at a price that makes sense. The optimized design of Thunder LED luminaires offer exceptional system efficiency and reliability you can count on. The entire system is designed with enhanced thermal dissipation performance that is dimensioned to surpass the applied power load. A heat sink with vertical fins is cold forged to provide superior thermal conductivity in a small footprint design that reduces cost and weight. Advanced thermal design paired with Nichia 757G chipset technology guarantees Thunder LED luminaires operate to their full potential over the guaranteed 5 years with minimal drop in the luminous flux. The Thunder LED luminaires utilizes Mean Well HBG Series LED power supplies to maximize circuit efficiency and raise overall reliability in a wide range of input voltages (90-295 VAC). The Thunder Series is offered in wattage options including 60, 100, 150 and 200 watts. By operating at 130+ lumens per watt over an extended, virtually maintenance-free lifespan, these high performing LED luminaires offer significant energy savings and reduced maintenance cost. The integration with an optional motion sensor or daylight harvesting module facilitates energy savings by dimming or on/off switching the luminaires that adapt to the environment and occupancy. Polycarbonate frosted lens over the light engine protects the optical assembly from dust accumulation and provides a diffused, low glare distribution of light. Optional 60, 70 and 90 degree aluminum and PC reflectors are available to shape the light distributions.
