Introduction: The Importance of Choosing the Right Lighting
There are so many factors to consider when picking out lights for a specific space, whether it be for a house, a busy office, or a commercial spaces that all have the same goal, illuminating the space. The lights that you use greatly determine the feel, functional capabilities, and even the energy consumption of the space. Panel lights and COB (Chip on Board) lights are two affordable options that are accessible today. In this blog, we will discuss the specifics of both technologies and help make a fitting decision for your situation.
As reported by the U.S. Department of Energy, about 15 % of the electricity used in a residential and commercial building is used on lights. Ensuring that the paintings and designs of your building are complimented by the lights greatly improves aesthetics and economic savings. So with all that said, picking lights is more important than most would think.

What is COB Light?
Definition and Technology Behind COB Lights
COB (Chip on Board) light technology incorporates multiple LED chips into one single module attached to a circuit board or substrate for improved efficiency and power. In simpler terms, COB is a new generation led lighting where LED chips are mounted directly onto the substrate or circuit board. With this vertical structure, there are a greater number of LED chips per area, leading to enhanced light output compared to standard LED setups.
These bulbs also provide far better light than other options, as there is no need to cover the LED dots that create each individual beam. As such, rather than casting out chunks of light, these bulbs release a more seamless and uniform illumination.
Advantages and Disadvantages of Using COB Lights
One benefit of COB lights is the focused beams with extreme brightness which emit a high intensity light. As such, they are best suited for task or accent lighting. In addition, COB lights can last over 50,000 hours which is cost effective in terms of maintenance and replacement.
On the other hand, like any other technology, COB lights do have their drawbacks. The more complex circuit design as compared to the other available LED options increases the cost of COB lights. As well, while the intensity of the light produced may be a benefit, it also makes COB lights unsuitable for any application where soft, diffused light is needed.

What is Panel Light?
Definition and Technology Behind Panel Lights
Panel lights, referred to as LED panel lights or LED flat lights, are fixtures that comprise a flat rectangular panel that contains many LED chips, casted inside bezel. These panels are designed to provide broad and uniform light output for a variety of general illumination applications and are ideal for use in various locations. The LED(SMD) chips are directly affixed to the PCB (printed circuit board) featuring the LED mounted device technology, which is more compact and thinner than existing fluorescent type fixtures.
Although most people think of LED panel lights because they are the most popular, long-lasting and energy-efficient, panel lights are nowadays available in various other technologies including fluorescent and incandescent.
Pros and Cons of Using Panel Lights
The main benefit of using panel lights is their versatility – they can be mounted on false ceilings, walls or even suspended from the ceiling. As a result, these lights can complement the designs of most modern settings very well.
Moreover, LED Panel lights have a beneficial feature; a wide beam angle, which ensures adequate lighting to large spaces and regions. Overall, they utilize approximately 20 to 30 percent of the power used by standard fluorescent lights. As a result, less power and impact on nature is less. Research suggests that installing LED panel light could reduce energy expenditure by 50 percent when compared to the fluorescent counterparts. However, these lights are not suitable for venues which required high brightness, focused beams or the use of high power COB lights due to their relatively shorter life spans of 30,000 to 40,000 hours of use.

Key Differences Between COB Light and Panel Light
Light Output and Brightness
When it comes to panel lights versus COB lights, there is no contest with brightness as the winner. COB technology enables an increase of LED chips in each light, which results in more focused and intense lighting. This makes COB lauded as the king of strong and directional lights, needed for spotlights, downlights, or task lighting. Such technology also generates brighter light with less heat, making them ideal for long use as there are no performance drops.
In contrast to COB, panel lights distribute dimmer light but focus on coverage as their main goal. While they are far from matching the competitiveness of brightness as it’s COB counterpart, panel lights are better suited for general illumination as they diffuse light and reduce glare and strain. Compared to COB panel lights do have fewer diodes, but they manage to gently light up spaces while remaining non-overwhelming.
Efficiency: Power Consumption Comparison
Both COB lights and panel lights are notable for their energy efficiency compared to traditional lighting solutions. However, there are differences in their power consumption that are worth noting.
Because of the lack of additional optical components, COB lights are able to produce a more intense lumen output per watt while consuming less power. A typical COB light achieves approximately 100-120 lumens per watt which indicates a higher efficiency rating.
Compared to fluorescent fixtures, LED panel lights have a far lower lumens per watt ratio, though they do still have a solid efficiency rating of 80-100 watts, making them a better choice for energy-conscious consumers.
Heat Management in COB vs Panel Lights
For effective usage of any LED lights, heat management is one of the most important factors. COB lights and panel lights employ different techniques for their thermal dissipation.
Because of their small sizes, COB lights are thermally more efficient. The LED chips are placed directly onto a substrate that has a heat sink. This lets the heat move away from the light source fast, allowing the COB light to operate at a stable temperature and extending its lifespan.
Panel lights have a larger surface area and are more thermally efficient than other forms of lighting. A Panel light’s heat sink or thermal management system reduces the risk of overheating. However, like smaller sized panel lights, they are not as efficient as COB lights.
Lifespan and Durability
Both COB lights and panel lights have a significantly longer lifespan compared to traditional lighting solutions. However, COB lights generally have a slight advantage in terms of durability.
COB lights, with their robust construction and fewer components, can withstand more challenging environments and are less prone to failure. They often have a lifespan of 50,000 hours or more, reducing the need for frequent replacements.
Panel lights, while still long-lasting, may have a slightly shorter lifespan due to their larger surface area and more complex construction. On average, LED panel lights can last between 30,000 to 40,000 hours, which is still impressive compared to traditional fluorescent fixtures.
In making your selection of lighting, keeping durability in mind is crucial as WOSEN is one of the top precision engineering companies that produces LED panel light fixtures.

Cost Analysis: COB Light vs Panel Light
When considering costs, there are quite a few factors that come into play. Their inherently higher cost is likely to be a factor if there are no budget constraints. Initially, COB lights may need a bigger budget in comparison to panel lights due to the inclined cost of design and output lumens. Over time, however, COB lights prove to be more cost effective because of their lengthy operating hours.
Panel lights are generally more affordable upfront, making them the best choice for large-scale installations or budget-conscious projects. Although not as cost efficient as traditional lighting, they are certainly a more economical option than COB lights.
In the end, when setting a balance between initial purchasing investment, energy use, maintenance, and deciding between COB lights and panel lights, it’s important to examine the total cost of ownership. Carefully consider your requirements for the best solution before making the decision between the adjustable light of COB and the reliable use of LED panel lights.
