586-6403-203F is a non-polarized yellow LED cluster lamp designed to directly replace incandescent miniature lamps in 14 VDC applications. The lamp features a peak wavelength of 592 nm with a typical intensity of 2000 mcd and forward current of 50 mA, delivering high brightness with significantly lower energy consumption than traditional incandescent bulbs. It incorporates AllInGaP or InGaN LED technology mounted in a T3 1/4 miniature bayonet (BA9s) socket, offering long operational life of up to 100,000 hours, shock and vibration resistance, and no heat generation. The product is ideal for indicator applications, control panels, and instrumentation displays where reliable, energy-efficient yellow illumination is required in 14 VDC systems.
