The K&F Concept 90cm Softbox (KF18.0020) is a large umbrella-style softbox designed to create softer, more controlled lighting for photography and video. With a 90cm (35.4-inch) diameter, its parabolic shape spreads light smoothly across your subject while producing attractive, rounded catchlights.
It also uses a standard Bowens mount, so you can pair it with a wide range of compatible COB lights, flashes, and LED video lights. As a result, it can easily become part of an existing studio or content-creation lighting setup.
Quick 5-Second Setup
One of the most useful features of the KF18.0020 is its quick-release construction. You can open or fold the softbox in around five seconds, which is particularly helpful when working alone or moving between different locations.
Instead of spending several minutes assembling traditional softbox rods, you can get the modifier ready quickly and start shooting.
90cm 16-Panel Circular Design
The softbox uses a 16-panel circular construction with a 90cm diameter. This design helps spread the light evenly while creating smooth transitions between highlights and shadows.
The circular front also produces rounded catchlights, making it particularly useful for:
- Portrait photography
- Wedding photography
- Product photography
- Commercial shoots
- Interviews
- Livestreaming
- Video production
Because the light falls off gradually, you can create a softer and more natural look without relying heavily on post-production.
Standard Bowens Mount
The K&F Concept 90cm Softbox features a standard Bowens mount, one of the most widely used lighting mounts for studio equipment.
This means you can use it with compatible:
- COB LED lights
- Continuous video lights
- Studio flashes
- Photography strobes
Therefore, you don’t need a special adapter when using a compatible Bowens-mount light.
Two Diffusers for Softer Light
The softbox comes with two removable diffusion layers. You can use the diffusers to soften the light and reduce harsh highlights, or adjust the setup depending on the look you’re trying to achieve.
The layers attach with Velcro, making them easy to install and remove when changing your lighting style.
Honeycomb Grid for Directional Control
A honeycomb grid is also included. It narrows the spread of the light and helps reduce unwanted spill onto the background or surrounding areas.
For example, when lighting a portrait subject, you can use the grid to keep more of the light focused on the person rather than allowing it to spread throughout the room.
The grid comes with a dedicated storage pouch that remains attached to the softbox, helping keep the accessory organized when it isn’t being used.
Useful for Studio and Location Shooting
Although the softbox is large enough for professional-looking portraits and product work, its quick-release design makes transportation easier.
It works well for both studio and on-location production, including solo shoots, interviews, livestreams, and content creation. The included carrying bag also makes it easier to transport and store the softbox between shoots.
Great for Portraits and Video
Soft lighting can make a major difference when recording people. The KF18.0020 creates a broad light source that helps soften facial shadows and produce a more flattering appearance.
For video, it can work well as a key light for:
- YouTube videos
- Interviews
- Podcasts
- Livestreams
- Social media content
- Commercial videos
- Studio productions
Meanwhile, photographers can use it for portraits, fashion, weddings, products, and other subjects where smooth and controlled illumination is important.
Portable Design for Content Creators
The K&F Concept 90cm Softbox is designed to pack down for transportation and storage. Its quick-release structure means you can spend less time assembling equipment and more time working on the actual shoot.
That makes it a practical choice for photographers and videographers who regularly move between a studio and different shooting locations.
