In addition to employing 12 LM80-certified, high-brightness LEDs with luminous flux of 4,000 lm each at 1 A, VLSL12A03-3Q3T-50A integrates thermal sensor and fourfold plug-in connector (87438-0443) that eliminate need for additional soldering. LEDs are serially connected on aluminum metal-core, single-side PCB (161 x 50 x 2 mm), and layout, compatible with LEDiL 2x2 STRADA and High Bay quadruple lenses, allows various emission patterns. Color temperatures range from 4700K to 5500K.
