LED drop-in replacement for 28-Volt DC, T3-1/4 "tubular shape" single-contact miniature bayonet base (Ba9s) miniature light bulbs. Common filament bulbs this led will replace include numbers: 313, 1818, 1819, 1820, 1820BTS, 1829, 1843, 1864, 1873, 757, 1437.Draws only 25mA @28VDC for 85% current reduction while also providing more total lumens. Voltage dependent dimming (led dims as forward voltage decreases). Dimensions are equivalent to filament version for a easy drop-in replacement. Opaque acrylic LED emitter is extremely durable and scatters the light to effectively provide balanced omni-directional light projection. Extremely efficient led technology generates no radiant heat, provides more light output than the filament versions, and is designed to last 50,000 hours. The ideal solution for upgrading indicator lights, control panel lights, and annunciators where safe, efficient and reliable lighting performance is critical.


*For a 28-Volt miniature bayonet LED replacement where more light output is desired (100 lumens),our #1495 LED REPLACEMENT may be an optimum replacement.
