Which is better, COB or LED?

When it comes to LED lighting solutions, two standout technologies are COB (Chip On Board) and SMD (Surface Mounted Device) LEDs. Both types bring their own set of benefits in terms of energy consumption, durability, and longevity. However, each serves different needs and preferences, especially in products like Unilite's work lights.

The Fundamental Differences

At the core of the comparison lies the construction and size. COB LEDs are distinguished by their larger size, comprising multiple chips directly affixed to a substrate. This construction leads to a high light output density and an efficient spatial arrangement. Conversely, SMD LEDs are smaller, featuring individual LED chips mounted on printed circuit boards (PCBs). While this results in lower light density, it affords greater design flexibility and placement options. For example, our IL-925R Folding Inspection Light integrates COB technology for the main lights while utilizing SMD for its top torch feature, catering perfectly to the needs of electricians, plumbers, and carpenters.

Light Distribution and Efficiency

Another significant distinction is the beam angle and light output. COB LEDs usually have a broader beam angle, delivering a more uniform and diffused light across larger surfaces, making them ideal for expansive work areas such as workshops or garages. For instance, the newest RF- and RF- Flood Lights leverage COB technology for this very reason. In contrast, SMD LEDs provide a tighter beam angle, making them excellent for focused or task-oriented lighting applications, such as in our popular PL-3 Aluminum Inspection Light, frequently used by emergency responders and technicians.

Energy efficiency remains a crucial factor when choosing between these technologies. While both COB and SMD LEDs demonstrate superior efficiency compared to traditional lighting, COB LEDs generally offer slightly enhanced performance due to their compact light output and reduced component count, contributing to extended lifespan. For illustration, our SLR- Compact Work Light employs a high-quality white COB LED.

Durability and Longevity

Durability is also paramount when selecting a work light. Both COB and SMD LEDs are known for their longevity and resilience. However, due to their robust construction and fewer components, COB LEDs typically outshine SMD counterparts in terms of durability. Our entire range of work lights undergo vigorous testing for strength and endurance prior to their release.

In conclusion, both COB and SMD LEDs are well-suited for various lighting applications, and we meticulously consider each option during the design process of our products. If your task requires broad and uniform light coverage, COB LEDs are an excellent choice. Alternatively, if focused lighting is your goal, SMD LEDs prove to be more advantageous. Both offer durability, efficiency, and long-lasting performance—traits that are integral to our philosophy at Unilite.
