LED Channel Lighting VS COB Strip Light

Considering the consistency of lighting, COB light strips are often compared with LED channel lighting

Composition

LED channel lighting consist of an extruded aluminum channel, a diffuser, end caps, and mounting accessories. They house LED strips and provide structural support. COB (Chip-on-Board) LED strips integrate multiple LED chips closely packed on a single circuit board, eliminating the need for additional housing.

Light Uniformity

LED aluminum profiles with frosted or opal diffusers help soften the light, reducing glare and eliminating visible LED dots. COB LED strips naturally offer a seamless lighting effect with no visible LED points due to their high LED density, making them ideal for applications requiring continuous illumination.

Flexibility

COB LED strips are highly flexible, allowing them to bend and conform to curved surfaces, making them suitable for creative lighting designs. LED aluminum profiles, though more rigid, offer better installation stability and are ideal for linear lighting applications in straight lines or predefined angles.

Heat Dissipation

LED aluminum profiles act as heat sinks, effectively dissipating heat and extending the lifespan of LED strips. COB LED strips generate more heat due to their high LED density, and without proper heat management, they may have a shorter lifespan.

Protection

Aluminum profiles provide physical protection against dust, moisture, and impact, ensuring longer-lasting LED performance. COB LED strips, while often coated with a protective layer, are more exposed to environmental factors and require additional shielding for durability in harsh conditions.

LED Channel Lighting vs. LED Neon Light

Efficiency

LED channel lighting, typically used with LED strips, offers high energy efficiency. The use of diffusers in aluminum profiles ensures the light is evenly distributed, reducing wasted light. LED neon lights, while also energy-efficient, tend to consume slightly more power due to their continuous form factor and thicker construction but still provide excellent lighting output for various applications.

Flexibility

LED neon lights are highly flexible and can bend in all directions, making them ideal for curved and intricate installations, such as signs and decorative designs. In contrast, LED channel lighting is generally more rigid, as it’s housed in an aluminum profile, which limits its flexibility, making it more suitable for straight-line applications like under-cabinet or linear lighting.

Heat Dissipation

LED channel lighting benefits from aluminum profiles that act as heat sinks, helping to efficiently dissipate heat and extend the lifespan of the LEDs. LED neon lights, however, are typically encased in a rubber or silicone jacket, which can restrict heat dissipation, leading to higher operating temperatures and potentially shorter lifespan if not properly managed.

Waterproof

Both LED channel lighting and LED neon lights are available in waterproof versions. However, LED neon lights are more commonly designed for flexible outdoor use and often come fully sealed in a durable silicone tube, offering better protection against water and harsh environments. LED channel lighting can also be waterproof, but the profile itself must be sealed properly, and the type of diffuser used may affect water resistance.
