Rang Dong's Adjustable COB Downlight Offers Precision, Elegance

For modern interiors where both aesthetics and functionality matter, the adjustable COB downlight model AT40 presented by Rang Dong, Vietnam’s leading manufacturer of LED products, should win the top choice. Thanks to its precise beam control and superior light quality, the fixture is designed for versatility and energy efficiency. In this article, let’s explore the specifications, standout features and diverse applications of this innovative downlight. 

Model AT40 is an adjustable COB (chip-on-board) downlight engineered to deliver superior performance and visual appeal. Equipped with a high-grade aluminum lamp body, the fixture integrates a COB (chip-on-board) LED chip and a die-cast aluminum heatsink to ensure efficient thermal management and extended lifespan. 

  

Structure of Rang Dong’s adjustable COB downlight, model AT40. 

Operating at 12W, the AT40 runs efficiently in a voltage range of 150-250V and a maximum input current of 160mA. It produces a luminous flux of 1020 lumens, achieving an efficacy of 85 lm/W.  

Users can select from three correlated color temperatures (CCTs): 3000K, 4000K, and 6500K, suitable for a wide range of ambiance needs. 

With a high color rendering index (CRI) of 90, the COB downlight offers vibrant and natural color representation.  

The 95-mm cut-out diameter means easy installation in standard ceiling openings. 

Certified by CE and KC, the product meets international standards for safety and performance.  

Model AT40 has a service life of up to 30,000 hours, reducing replacement frequency and long-term maintenance costs. 

Exceptional features 

The standout feature of the Rang Dong AT40 adjustable COB downlight is its dynamic beam adjustability.  

With a tilt range from-20° to 20°, users can direct the light exactly where needed, creating focused or ambient lighting effects with ease. This flexibility enhances the functionality of the space, making it perfect for accent lighting, display areas or general room illumination. 

 

Model AT40 meets the diverse needs of contemporary spaces.  

COB LED technology gives a high-intensity, uniform beam without multiple shadows, delivering a clean and professional look. Its isolated driver enhances safety and performance by maintaining electrical separation between the high-voltage and low-voltage components. 

The downlight also includes a high-quality diffuser that softens the light output, reducing glare and improving visual comfort. This feature is particularly important in environments such as offices or commercial centers, where lighting leaves a significant impact on productivity and mood. 

The AT40's construction not only contributes to performance but also to aesthetics. The sleek, minimalist design blends seamlessly with modern interiors, and its sturdy aluminum build ensures durability in high-traffic environments. This feature makes the downlight not only a practical choice but a stylish one as well. 

Applications 

Rang Dong’s adjustable COB downlight is suitable for a wide array of indoor lighting applications.  

In residential settings, it offers precise and flexible lighting for living rooms, kitchens and bedrooms, enhancing both function and design. 

  

The installation of adjustable COB downlights is determined by factors such as room size, desired lighting effect and furniture placement. 

In commercial environments such as offices, restaurants and hotels, model AT40 creates a welcoming and visually appealing atmosphere. Its ability to highlight specific areas or objects makes it ideal for showrooms, galleries and retail spaces. 

The AT40 downlight can also serve best in supermarkets and commercial centers, where consistent, energy-efficient lighting is critical. Its long lifespan and high performance reduce the need for frequent maintenance, making it a cost-effective solution for large-scale installations. 

Whether it's for cozy home corners or dynamic business venues, model AT40 delivers both performance and sophistication.
