#313, 1818, 1819, 1820, 1829, 1864 LED Replacement  |  28-Volt (Ba9s base)

A premium quality LED drop-in replacement for 28-Volt AC/DC, T3-1/4 "tubular shape" single-contact miniature bayonet base (Ba9s) miniature light bulbs. Dimensions are identical to filament version for a no-questions drop-in replacement. The lamp features a high quality surface-mount led affixed to an aluminum heat sinking chassis for superior heat dissipation. An opaque polycarbonate lens cover provides an unbreakable shell while distributing 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 thousands of trouble-free hours. The ideal solution for upgrading indicator lights, control panel lights, and annunciators where safe, efficient and reliable lighting performance is critical.

*By using only premium components, our BRIGHT WHITE color is snow white, unlike virtually all other leds in the market which utilize inferior components and cast a blue/purple hue 

*Save up to 15% by ordering multi-packs


Common filament bulbs this led will replace include numbers: 313, 1818, 1819, 1820, 1820BTS, 1829, 1843, 1864, 1873, 757, 1437.


*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.
