The FF200-0UY-028B is a miniature wedge-base LED indicator bulb designed as a direct incandescent replacement for control panels, elevators, and industrial applications. It operates at standard voltages of 24 VDC and 28 VDC with positive (+) polarity, featuring a compact base outer diameter of 0.20" (5.08 mm) and a maximum overall length of 0.80" (20.32 mm). The single-chip ultra-bright design delivers up to 90% energy savings compared to incandescent equivalents while providing a long operational lifespan with no heat generation, making it ideal for high-shock and high-vibration environments. Available in multiple colors including warm white, cool white, red, yellow, and green, this solid-state LED bulb is commonly used in motor control panels, avionics, utility control panels, and military/aerospace indicator applications, backed by a 3-year LEDtronics warranty.
