Guangmai Technology 2828 Flip Cob Led 30w 40w 50w 60w 28*28 Size

COB (Chip On Board) LED and SMD (Surface Mounted Device) LED are two popular technologies used in LED lighting, including Unilite work lights. Both offer advantages in terms of energy efficiency, durability, and lifespan, but there are some key differences to consider when reviewing the Unilite lineup. We utilize both LED technology in our flashlights, site lights, inspection lights, lanterns and headlamps.

One of the main differences between COB and SMD LEDs is their size and design. COB LEDs are larger and consist of multiple LED chips that are mounted directly onto a substrate. This allows for a higher density of light output and a more efficient use of space. In contrast, SMD LEDs are smaller and consist of a single LED chip that is mounted onto a printed circuit board (PCB). This results in a lower density of light output but allows for more flexibility in design and placement. In our best-seller, the IL-925R Folding Inspection Light features COB LED for the two primary lights and an SMD LED for the top torch, making it perfect for plumbers, electricians and carpenters.
