Weeylite Ninja 400 Bi-Color COB LED Video Light

by | Dec 21, 2020 | Gear and Reviews, Lighting

I’m diving into an in-depth review of the Weeylite Ninja 400 Bi-Color COB LED video light. This affordable and versatile light has caught my attention, and I’m here to break down its features, performance, and how it stacks up against the competition.

Overview of the Weeylite Ninja 400

The Weeylite Ninja 400 is a budget-friendly COB LED light that offers a range of features making it a versatile tool for various on-set scenarios. Priced at around $370, it’s a 150-watt bi-color temperature light, ranging from 2500K to 8500K.

Key Features

  • CRI and TLCI Ratings: With a CRI of 95 and a TLCI of 98, it promises good color accuracy.
  • Dimming: Offers stepless dimming from 0% to 100% brightness.
  • Power Options: Can be powered by DC power or V-mount batteries (sold separately).
  • Control Options: Includes a standalone control unit, a remote, and a companion app for mobile control.
  • DMX Control: Features DMX inputs for integration into a broader lighting setup.
  • Carry Case: Comes with a quality padded carry case for easy transportation.

Build Quality

The build quality is robust, suitable for regular use on set. It may not match the build quality of higher-end lights like the Aputure 120D Mark II, but it’s sturdier than other budget options like the Godox SL160 or the Pixel C100.

Performance and User Experience

Light Output

  • Brightness: The Ninja 400 is very bright, with Viltrox claiming 716 lux at one meter. It’s comparable to the Aputure 120D Mark II in terms of brightness.
  • Real-World Usage: In practical scenarios, such as a talking head setup, the light performs well at 30-40% brightness when paired with a 70cm parabolic softbox.
  • Dimming: The light dims smoothly, although at 1%, it’s still quite bright.

User Experience

  • Quick Release Yoke Lock: Provides a secure and easy-to-adjust mounting system.
  • Mounting Options: Can be mounted vertically or horizontally.
  • Remote and App: The remote is functional and uses AAA batteries, while the app offers a user-friendly interface for light control.
  • Fan Noise: The fan is quiet, unlikely to cause issues even in quiet scenes.

Quality of Light

  • Color Accuracy: The light performs well at extreme color temperatures (2500K and 8500K). However, at midpoints like 5600K, the color accuracy may not be as high.
  • Consistency: The dimming can be inconsistent when mixing warm and cold LEDs for mid-range color temperatures.

Comparison with Competitors

  • Budget Constraint: If you need a bi-color COB LED light at a budget, the Ninja 400 is a strong recommendation.
  • Aputure 300X: For those where budget is less of a concern and color accuracy is crucial, the Aputure 300X, though more expensive, offers better color accuracy.
  • Godox VL150: If bi-color is not a necessity, the Godox VL150 might be a better option for a fixed 5600K light, offering similar build quality and better color accuracy at a similar price point.


The Weeylite Ninja 400 is a great option for those needing an affordable bi-color COB LED light. While it may not match the highest-end lights in build quality or color accuracy at mid-range temperatures, its versatility, brightness, and price point make it a valuable tool for many filmmakers and content creators.
