MGSW28 is a T1¼ Midget Groove single-chip based LED lamp that serves as an energy-efficient replacement for traditional filament lamps. It operates at 28VDC with a current draw of 1.4 mA and provides a luminous intensity of 2070 mcd in white color. The LED offers significant advantages over filament lamps including long lifetime (typically 100,000 hours), low power consumption, low heat generation, and excellent shock and vibration resistance. This based LED lamp is ideal for use in pushbutton switches, indicators, and critical applications where reliable indication is important or where lamp replacement is difficult or costly.
