Engineered with smart constant-current technology and superior heat dissipation, optimized for the high-temperature industrial landscape of Rajshahi.
As the regional urban hub of northern Bangladesh, the Rajshahi metropolitan division is experiencing a significant industrial and architectural transformation. From the traditional silk mills of the BSCIC Industrial Estate in Rajshahi to the modern warehousing facilities built for mango and agricultural storage, regional logistics demand efficient, long-lasting illumination. High-power LED corn lights have emerged as the standard retrofit choice for replacing aging High-Intensity Discharge (HID) and High-Pressure Sodium (HPS) installations. Local factories, university campuses (such as RUET and Rajshahi University), and urban planning divisions face common lighting challenges: high ambient summer temperatures, humidity, and the need to reduce overhead electricity costs. Guangdong Cool Lighting Electronic Co., Ltd. addresses these requirements by manufacturing robust, IP64/IP65 waterproof corn lamps engineered for continuous duty under harsh industrial conditions.
Traditional metal halide and HPS lamps generate light by passing an electric arc through gaseous metals. This process converts up to 70% of energy input into heat, presenting thermal management challenges inside warehouse structures. Our LED corn lights operate with luminous efficacies of up to 130–150 lm/W. By switching to our high-bay LED series, a facility replacing a 400W metal halide fixture can transition to a 100W or 120W LED corn bulb. This achieves over 70% direct energy savings while reducing the cooling load on HVAC systems in Rajshahi's warm climate zones.
Additionally, our corn light models feature a 360-degree beam angle configuration, ensuring uniform horizontal and vertical illuminance. The array of surface-mounted device (SMD) chips replicates the omnidirectional distribution pattern of traditional bulbs, making them compatible with existing reflector housings without requiring optical modifications.
Guangdong Cool Lighting Electronic Co., Ltd. combines high-volume production with global quality compliance.
Select the optimal wattage, base type, and lumen package for your commercial retrofit project.
| LED Bulb Wattage | Equivalent HID/HPS | Lumen Output (Avg) | Base Configurations | Primary Industrial Applications |
|---|---|---|---|---|
| 9W - 24W | 50W - 75W | 1,170 - 3,120 lm | E26 / E27 / G9 / E14 | Residential corridors, task lighting, local refrigeration units. |
| 36W - 60W | 100W - 175W | 4,680 - 7,800 lm | E27 / E39 / E40 | Low-bay warehouses, local street poles, perimeter safety lighting. |
| 80W - 100W | 250W - 350W | 10,400 - 13,000 lm | E39 / E40 / EX39 | Industrial storage facilities, high-tech parks, outdoor parking areas. |
| 120W - 175W | 400W - 600W | 15,600 - 22,750 lm | E39 / E40 | High-ceiling logistics centers, municipal roads, public spaces. |

Implementing large-scale commercial retrofits in public domains or industrial factories requires an understanding of mechanical and thermodynamic parameters. A primary failure mode for high-bay lighting is thermal degradation of the driver capacitors. When retrofitting sealed fixtures, heat buildup can accelerate component degradation. Our engineering processes mitigate this by utilizing fin-aluminum heat sinks with convective airflow designs.
Universal Voltage Input: Our core ranges accept input voltages between 100-277VAC, managing minor fluctuations. High-voltage protection circuits shield the internal driver components from phase abnormalities.
CCT Options: Available in 3000K (Warm White) up to 6500K (Cool White/Daylight). We recommend 5000K to 6000K for warehouse and assembly floor installations to enhance visual acuity and operator safety.
High-Intensity Discharge (HID) fixtures utilize ballasts to control starter current and operational voltage. Because LED corn lamps operate with integrated, direct-wire constant-current drivers, the existing ballast must be bypassed before installation. Retaining the ballast can cause immediate driver failure and void the warranty.
