What Is a COB Light: Usage & Advantages Explained

By Tati Taylor 16 days ago, Lighting & Studio

COB light, or Chip-on-Board light, leverages the power of LED lighting technology and consists of LED chips attached to a circuit board. As a result, it becomes an efficient solution for those who are looking for a powerful light source supporting high brightness.

As a retoucher with years of experience, I know how to edit COB light photos and what makes them different from photos taken with the help of other types of light sources.

Acquiring an in-depth understanding of COB lights is crucial for those who want to minimize power consumption at home, install cost-effective lighting at their business facilities, or take photos using different light sources, depending on the situation.

Advantages

COB lights are known as one of the best LED lights for videos and photos. Many professionals prefer to utilize them due to their excellent brightness, which is achieved thanks to the specific LED chip combination.

Due to the high density of chips mounted to the circuit board, consistent light distribution becomes possible. This light source does not produce noticeable highlights and deep shadows, which allows it to illuminate a wide area.

In addition, thanks to the compact design of such light sources, they can be used in small rooms or in situations that do not require high-profile lighting.

One of the main selling points of COB lights is that they stand out for their excellent thermal management. COB lights consist of LED chips directly connected to a circuit board, which allows them to dissipate heat with high efficiency and remain in a functioning state longer. Thanks to this, the owners of such light sources should not worry about possible malfunctioning of these lighting devices.

COB lights stand out for their color rendering capacity, which allows photographers to capture the colors of objects with high precision. Whether you use Philips COB light or other models, they are perfect for those who are interested in a high level of clarity and detail, which makes them perfect for those who value high color accuracy. This is why they are highly valued by retail business owners and are often installed in art galleries.

Another advantage of COB lights is that they last for a long time. Provided a user performs regular maintenance to ensure their stable operation, COB lights will have an impressive lifespan. Due to this, their owners can save money on replacements and maintenance.

Besides, COB lights stand out for directional control features and allow adjusting light output. They are suitable for creating beam angles and lighting effects. This option allows them to be used for task and accent lighting. Besides, they are perfect for spotlighting, as they produce focused illumination.

Cases of Usage

COB lights are used in many situations where high brightness and low energy consumption are crucial. Below, I have outlined the main cases when everyone can benefit from utilizing COB lights:

Task Lighting: COB lights stand out for their capacity to fully illuminate specific environments, including offices and workspaces where people benefit from good lighting.

Accent Lighting: Due to excellent brightness levels and directional capabilities, COB lights are best suited for emphasizing specific areas or elements of buildings and interior decor.

Outdoor Lighting: COB lights have a long lifespan and are fully weather resistant, which makes them an excellent choice for outdoor use. They are perfect for landscape, security, and pathway lighting.

Commercial Settings: Owners of retail stores, galleries, and exhibitions often install COB lights as they make products and artwork stand out and fully transform the atmosphere by making the interior more welcoming.

Industrial Environments: COB lights are often used at large storage and manufacturing facilities, including factories and warehouses as they have a specific design that prevents them from being damaged.

Residential Lighting: COB lights illuminate every area of a house, which is why they are used as sources of ambient light in living rooms, bathrooms, kitchens, and other spaces. Besides, a COB LED light strip can be used as an element of exterior lighting setups.

Photography: COB lights are a must for every photographer who wants to get a professional studio lighting kit. They serve as a source of consistent lighting and allow adjusting its intensity with ease. Thus, these light sources are perfect for taking pro-level photos without sharp shadows and highlights.

COB vs SMD Comparison

When comparing such LED lights for photography and SMD (Surface Mount Device), one might notice that they have different designs, performance, and use cases. Besides, they are built in different ways.

Below, I have outlined the main features that set them apart from each other. In this table, you will find their key differences and learn what is a COB light bulb.

COB LED Lights: The Most Trusted Options

If you want to select the best COB LED light for your needs, pay attention to its luminosity (it is measured in lumens). You should also consider the supported lighting modes, reliability, and build quality. Waterproof solutions are suitable for outdoor use.

Viltrox Ninja 10

As a photographer who often organizes studio photoshoots, I prefer to always keep Viltrox Ninja 10 at hand. It does not take up a lot of space, which allows me to take it with me anywhere. I can use it to improve lighting in every situation.

However, what makes this model especially useful for me is that it supports impressive brightness. Due to a COB LED, it illuminates the whole area and enables me to capture stunning photos even in poor-light situations. Regardless of the type of light source I use, be it a key, fill, or accent light, utilizing the Ninja 10 allows me to achieve uniform lighting by minimizing shadows and avoiding highlights.

SmallRig RC 350B 350W

Enhancing photos taken with COB lights requires using a more careful approach than editing pics taken with SMD lights because the quality of light, color rendering, and shadows is different.

As I often need to edit photos taken with COB lights, I noticed that they have uniform lighting, which is why I do not need to spend a lot of time fixing issues with glare and excessive shadows. I can achieve a well-balanced exposure and precise color rendering when enhancing my pics. Besides, COB lights allow me to take professional-quality photos with accurate colors and realistic skin tones.
