Product Description
The Sphere Top T-Shape LED Bulb is our specialized solution for environments that demand 360-degree light distribution combined with high-output industrial performance. At 50W, this model features a unique spherical top designed to eliminate the "cone of shadow" often found in flat-top T-shape bulbs. Since our founding in 1996, we have consistently pushed the boundaries of traditional bulb geometry to solve real-world lighting challenges. The Sphere Top T-Shape LED Bulb delivers 5,000 Lm of powerful, diffused light, making it a masterpiece for large open spaces where uniform visibility is critical. Our automated assembly machines ensure that the spherical diffuser is perfectly seated, providing a seamless light source that is as durable as it is efficient.
For international wholesalers and importers, the Sphere Top T-Shape LED Bulb provides a unique selling point in the high-wattage market: "Total Illumination." Unlike standard bulbs that concentrate light downward, this model fills a room with light from all angles, making it a favorite for showrooms and large residential halls. As a direct-source manufacturer, we utilize premium HB-grade materials to ensure the 50,000-hour rated lifespan remains stable under the high power factor (PF0.5/PF0.9) of this 50W unit. By choosing this series, you are providing your customers with an innovative lighting tool that bridges the gap between a standard bulb and a professional fixture, backed by our 30-year legacy of manufacturing excellence.
