The E27 E40 LED Haina Diamond T Bulb is a high-lumen lighting solution designed for commercial and industrial environments. Featuring a diamond-cut structure and durable aluminum housing, it offers superior brightness, efficient heat dissipation, and long-term performance.
The E27 E40 LED Haina Diamond T Bulb is a high-power LED lighting solution engineered for large commercial and industrial spaces. Its distinctive diamond-cut T-shaped design increases surface area, improving heat dissipation and light diffusion. This structure allows the bulb to maintain high brightness while operating at lower temperatures.
Designed with standard E27 and E40 bases, the Haina Diamond T Bulb is compatible with a wide range of existing fixtures. This makes it an ideal replacement for traditional metal halide, mercury vapor, or HID lamps in retrofit projects.
The Haina Diamond T Bulb delivers powerful illumination suitable for high-ceiling and open-area environments. Its high lumen efficiency ensures bright, uniform light coverage with fewer fixtures.
The diamond-cut aluminum housing enhances airflow and accelerates heat transfer. Efficient thermal management helps maintain consistent light output and extends the bulb’s lifespan.
Thanks to optimized thermal control and high-quality LED components, the bulb typically achieves a lifespan of 30,000 hours, reducing maintenance and replacement costs.
Compared to traditional high-wattage lamps, the LED Haina Diamond T Bulb consumes significantly less power while delivering equal or higher brightness. This results in lower electricity bills and improved energy efficiency.
The E27 E40 LED Haina Diamond T Bulb is widely used in demanding lighting environments, including:
Provides strong and uniform lighting for storage areas, loading docks, and aisles.
Supports continuous operation with stable brightness for production lines and workspaces.
Enhances product visibility and creates a bright, comfortable shopping environment.
Improves visibility and safety in large enclosed or semi-enclosed areas.
Commercial and industrial projects require lighting solutions that are reliable, scalable, and easy to install. The E27 and E40 bases allow direct replacement of traditional lamps without fixture modification. This reduces installation time and labor costs.
Bulk procurement of LED Haina Diamond T Bulbs ensures consistent quality, uniform lighting performance, and cost efficiency across large projects.
The E27 E40 LED Haina Diamond T Bulb for Commercial and Industrial Lighting combines high lumen output, efficient thermal management, and long-term reliability. Its diamond-cut design and standard base compatibility make it an ideal choice for both new installations and retrofit projects. For businesses seeking energy-efficient and durable lighting solutions, this LED T bulb delivers exceptional performance and value.
