Frequently Asked Question:

What is the difference between COB and SMD cree led high bay?


Answer:

Lighting technology keeps on changing, and this change has been more evident in the last few years as companies are trying to manufacture more efficient light sources for the market. COB and SMD Cree led high bay lights are perhaps two of the most popular lights currently on the market. As popular as they may be many people are not able to tell them apart and in most cases some people choose randomly between them. However, the two lighting technologies are very different from each other in many ways and understanding the differences should help you select the right light for you.


The main or the most evident difference between the two is their physical appearance. The SMD Cree led high bay is physically larger and has a wider PCB area than the COB. This might look like a small design issue, but it has a lot of functionalities and is one of the key differences between the two. When in use, both the LEDs produce a lot of heat. This is as a result of the mechanism or technology behind them. If this heat is not dispersed properly, it will significantly reduce the lifespan of the light. By virtue of being bigger and wider the SMD can dissipate more heat from the light into its surroundings meaning that it lasts longer.


Another difference stems from the quality of light that the two produce. Although both of them provide a top notch quality of light, the light produced is not entirely similar. However, this will probably not be evident to an untrained eye. The packaging of COB utilizes an integrated style meaning it is an area light source and hence producing a big visual angle. Another advantage with this is that it is also easy to change and reduce the loss of refraction light. The SMD, on the other hand, is made up of many discrete units stuck on the PCB plate. This has many advantages including a uniform luminance.


Both the lights are made using some of the very latest technologies in the industry and as seen above each one of them has its own merits and demerits. Despite this SMD is what most people prefer as it is considered better than the COB. Although both have the potential to give you the light that you require, the SMD will serve you for way much longer than the COB. Due to this, it is the better option for you when choosing between the two. The next time you go shopping for a good lighting the above differences should help you make an informed decision.
