When you’re ready to move beyond basic lighting and elevate your content to a professional level, a big ring light is the single most important investment you can make. As a photographer and content creator with over a decade of experience, I’ve seen firsthand how the right light can transform good work into great work. It’s the secret weapon behind those flawless portraits, perfectly lit videos, and stunning makeup tutorials you see online. But with so many options, how do you choose the right one?

This comprehensive guide is here to demystify the world of large ring lights. We’ll explore why size matters, what technical specs to look for, and how to find the perfect big ring light to match your creative vision. Let’s illuminate your potential.
What Is Considered a Big Ring Light?
While there’s no official industry standard, a ring light is generally considered “big” when its diameter is 18 inches or larger. The most common large sizes you’ll find on the market are 18-inch, 20-inch, and even massive 24-inch models. These larger sizes are designed to cast a wider, softer, and more enveloping light, making them ideal for professional applications.
A smaller 10 or 12-inch ring light is great for selfies and desk-based video calls, but a big ring light is a true studio tool. It can illuminate a much larger area, which is essential for half-body or full-body shots, group photos, and creating a more sophisticated lighting environment.
Why You Need a Larger Ring Light
Is a bigger ring light always better? For professional results, the answer is often yes. A larger light source produces a softer, more flattering light. Think about the difference between a bare lightbulb and a large window—the window’s light is softer and wraps around you, minimizing harsh shadows. A big ring light works on the same principle.
Key benefits include:
- Softer, More Flattering Light: A larger surface area diffuses the light more effectively, smoothing out skin texture and reducing harsh shadows that can accentuate wrinkles and blemishes.
- Wider Coverage: It can illuminate a larger subject or area, making it perfect for vlogging, streaming setups, full-body shots, and lighting multiple people at once.
- Bigger, More Dramatic Catchlights: The signature “halo” catchlights in the eyes become larger and more pronounced, creating a captivating and professional look in portraits and videos.
- Greater Versatility: A big ring light is powerful enough to be used as a main light source (key light) from a distance, whereas smaller lights must be kept very close to the subject.
How to Choose the Best Big Ring Light
Navigating the technical specifications can be confusing. Let’s break down the most important features to consider when shopping for your professional lighting upgrade.
Size (Diameter)
The size you need depends on your primary use.
- 18-inch: This is the most popular professional size and the perfect entry point into big ring lights. It’s incredibly versatile for beauty tutorials, headshots, and streaming. It provides beautiful, soft light without being overly bulky.
- 20 to 22-inch: A step up for those who need to light a wider area. This size is excellent for photographers shooting portraits or content creators who film from the waist up.
- 24-inch and larger: These are studio-grade behemoths. A 24-inch ring light is ideal for fashion photography, full-body shots, and creating video content in a large space. It delivers incredibly soft light and maximum coverage.
Brightness and Power (Lumens & Watts)
Brightness, measured in lumens, is crucial. A big ring light should be powerful enough to overpower other ambient light in the room. Look for models that offer adjustable brightness settings, allowing you to dial in the perfect intensity for any situation. The power, measured in watts, often correlates with brightness. For a large ring light, look for models that are 45W or higher to ensure you have enough output.
Color Temperature
Color temperature, measured in Kelvin (K), refers to how warm (yellow) or cool (blue) the light is. For maximum versatility, choose a bi-color ring light that allows you to adjust the temperature.
- 3200K: A warm, tungsten-like light, great for a cozy, inviting feel.
- 5600K: A cool, natural daylight-like light, ideal for most photography and video applications.
An adjustable range from 3200K to 5600K gives you complete creative control, allowing you to match the ambient light in your room or create a specific mood.
Color Rendering Index (CRI)
CRI measures a light’s ability to accurately reproduce the colors of the object it illuminates, on a scale of 0 to 100. For any work involving color, such as makeup artistry or product photography, this is a non-negotiable feature. Always look for a ring light with a CRI of 95 or higher. A high CRI ensures that skin tones look natural and product colors appear true to life on camera.
As professional makeup artist, Alexandra Chen, states, “Using a ring light with a low CRI is a disaster. It can make a perfect foundation match look completely wrong on camera. A high-CRI light is essential for trusting that what you see in the monitor is true to reality.”
Essential Accessories
The right accessories will make your big ring light even more functional.
- A Sturdy Stand: A large ring light is heavy. Ensure it comes with a robust, stable, and adjustable tripod stand that can extend high enough for your needs (at least 6 feet is recommended).
- Phone and Camera Mounts: Check for versatile mounting options. Most come with a smartphone holder, but if you use a DSLR or mirrorless camera, ensure there’s a proper mount for it.
- Carrying Case: A padded carrying case is essential for protecting your investment, especially if you plan to transport it for on-location shoots.
- Remote Control: A remote makes it easy to adjust brightness and color temperature without having to step away from your camera.
Frequently Asked Questions (FAQ)
What is the best size ring light for streaming?
An 18-inch ring light is typically the best choice for streaming. It’s large enough to provide soft, flattering light for a head-and-shoulders shot without taking up excessive space in your setup.
Can you use a big ring light for full-body shots?
Yes, a 20-inch or 24-inch ring light is powerful and wide enough to be used for full-body shots. You’ll need to position it further back and higher up to cast an even light across the entire subject.
How far away should a big ring light be?
For portraits and headshots, a distance of 2 to 4 feet is ideal. For larger shots or a softer effect, you can move it further back. The key is to experiment to see what works best for your specific scene and desired effect.
Do I need a diffuser for my ring light?
Most modern LED ring lights come with a built-in diffusion panel, which is the milky white plastic that covers the LEDs. This is usually sufficient to create soft light, so an extra diffuser is typically not necessary.
Is one ring light enough?
For many applications like vlogging, makeup tutorials, and portraits, a single big ring light is absolutely enough. It serves as your key light and fill light all in one. For more complex, cinematic setups, you might add other lights, but a large ring light is the best starting point.
The Final Verdict
Upgrading to a big ring light is a game-changer for anyone serious about the quality of their photos and videos. It provides the soft, beautiful, and professional illumination that smaller lights simply cannot replicate. By focusing on the right size for your needs and paying attention to key specs like bi-color capability and a high CRI, you can invest in a tool that will serve you for years to come. Now go ahead, step into the circle of perfect light, and show the world your content in the best way possible.
