With its unique universal adjustment feature, all-in-one intelligent control system, and efficient heat dissipation, this bulb offers an energy-efficient, versatile, and smart solution to cater to all your lighting needs. Available in power levels from 65W to 120W.

Enhance your industrial lighting environment with the SmartBright E40 Retrofit High Bay LED Bulb, a versatile and dynamic lighting solution that transcends traditional, single-function industrial lighting. Available in power levels ranging from 65W to 120W, this innovative LED bulb caters to diverse lighting requirements in complex and changing industrial scenarios.

Our SmartBright E40 bulb incorporates a revolutionary universal adjustment feature, allowing users to customize the lighting angle without having to reposition the lamp. This makes it perfect for achieving precise directional lighting requirements, a characteristic traditionally hard to attain with standard industrial lighting.

The SmartBright E40 is equipped with an all-in-one intelligent control system. It accommodates multiple adjustments including power level, color temperature, and remote control via Wi-Fi or Bluetooth. Additional features such as radar, infrared, and light control extend its versatility and adaptability, ensuring that it meets all your lighting needs, enhancing productivity while promoting energy efficiency.

At the heart of the SmartBright E40 LED bulb lies a light source board directly attached to a pure aluminum radiator, facilitating superior and efficient heat dissipation. The bulb is fashioned in an industrial-style design, with cooling teeth aligned with airflow, ensuring optimal cooling during high-intensity usage. The sharp-edged metal texture and unique industrial design style offer a sophisticated aesthetic appeal, a testament to the thoughtfulness behind its creation.

Durability is a key component of the SmartBright E40 LED bulb. It boasts a spring-piston mechanical internal structure, promising up to 100,000 free rotations. Adjust the angle and control the rotation with precision thanks to clearly visible scale marks and a delightful metallic damping sound.

The bulb comes with a smart NTC probe that continuously monitors the temperature of its high-temperature components. If the driver temperature exceeds the normal preset value, the bulb’s power is automatically adjusted to prevent overheating. Once the driver temperature returns to the preset value, power is automatically restored to the standard level.

Moreover, users can flexibly adjust the color, power, and brightness of the lamp, facilitating energy saving and emissions reduction, all while satisfying various lighting needs.

Our patented signal power supply external intelligent interface allows for easy plugging and unplugging. Five additional control modules are available for purchase separately: IR Sensor, Radar Sensor, Photocell Sensor, APP Wi-Fi Control, and BT Mesh Control. These plug-and-play modules provide a convenient carrier for intelligent control methods, creating more possibilities for versatile and efficient control.

The SmartBright E40 LED bulb is made of durable die-casting aluminum and PC materials, supporting an input voltage of AC100-265V. The lamp offers a beam angle of 120°, which is adjustable both horizontally and vertically, providing 130LM/W and a color rendering index (CRI) of over 80RA. The bulb uses high-quality Epistar, Sanan, or Osram LED chips, with manual switching between color temperatures of 3000K, 4000K, and 6500K. Installation options include E40 E39 E27 E26 B22 and Hoisting, for greater flexibility.

In summary, the SmartBright E40 Retrofit High Bay LED Bulb offers a sophisticated, versatile, and energy-efficient lighting solution, surpassing standard industrial lighting and paving the way to a brighter, smarter future. By the way, our another model EcoBright E40 LED Bulb is also recommended for your choice.
