The miniature incandescent bulb is designed to provide high-quality, bright light with an output of 1.26 watts and 105 lumens. Its T1-3/4 size makes it ideal for small spaces or tight fixtures, while its base type is suitable for a range of lighting applications. The filament is crafted from quality materials ensuring durability and long life expectancy. With the capability to generate vibrant white color light, this bulb can be used in diverse settings such as holiday decorations, automobiles, or household fixtures requiring a small yet powerful illumination solution.
These T-shaped miniature light bulbs have a single-contact (SC) bayonet base, sometimes known as a BA15s base. There is one contact on the bottom of the base. The base has lugs on either side that lock the bulb in place when the bulb is pushed into a compatible socket and twisted.
