Introduction
The Zhiyun Molus B500 is the most powerful model in a new series of bi-colour LED COB lights from Zhiyun. This series includes four units with power ratings ranging from 100W to 500W. Zhiyun, better known for its Crane system of gimbals for DSLR and mirrorless cameras, has ventured into the LED lighting market, capitalizing on the reduced costs compared to a few years ago. The Molus B500 stands out for its affordability and compact design, eliminating the need for bulky power packs.
Specifications
The Molus B500 is a 500W LED COB light with a variable colour temperature between 2700 and 6500K. Zhiyun claims it delivers 19200 lux at 1 meter with the temperature set to 5500K and 76400 lux with the supplied reflector. The light boasts a CRI (RA) of over 95 and a TLCI of over 97. Additionally, the TM-30 measurements indicate a colour fidelity (Rf) of 94 and a gamut index (Rg) of 101, suggesting slightly over-saturated colours but overall accurate colour representation. Despite its built-in power adapter, the head is remarkably small, measuring 245x190x159mm and weighing just 2.8kg. It also features a Bowen’s S-Type accessory mount.
Handling and Design
The Molus B500 is visually appealing with its chrome metal cages, blue fan blades, and dramatically ribbed surfaces. The housing, full of ventilation holes, adds to its rugged look. Despite its compact size, the plastic body feels brittle, though it is commonly used in similar products. The light features a plastic attaching mount that feels well-made, and the main handle allows for easy angle adjustments and 360° rotation. An umbrella pole slot and a conveniently placed power cable fitting enhance usability, although the cable’s position can inhibit upward angling of the light.
Control and Functionality
The light’s intensity and colour are controlled by two large dials on the rear, protected by plastic shields. The brightness dial adjusts in 1% increments and the colour temperature dial shifts in 100K increments, with both offering shortcut functions. A small display panel provides setting information, though it can be hard to see when the light is mounted high. The ZY Vega app offers more intuitive control, allowing colour temperature matching, CCT gel effects, and memory settings for multiple lights.
Performance
The Molus B500 performed well across various projects, maintaining consistent colour balance from 100% down to 5% output. However, a custom balance was needed to achieve a clean grey at 5600K due to a slight purple shift. The powerful cooling system, although initially loud, was significantly quieted by a firmware update. The update process was straightforward, either via USB or the ZY Vega app.
Price & Availability
Retailing at $719 USD, the Zhiyun Molus B500 offers good value but faces stiff competition from more established brands. Despite this, its combination of power, compact design, and advanced features make it a compelling option for those in need of a robust bi-colour LED light.
Conclusion
The Zhiyun Molus B500 Bi-Colour Studio Light stands out in the competitive LED lighting market with its powerful 500W output, compact design, and affordability. Its ability to deliver consistent and accurate colour representation, combined with the convenience of a built-in power adapter and user-friendly controls, makes it a versatile choice for various lighting needs. While it does face competition from more established brands, its features and performance make it a compelling option for both amateur and professional photographers and videographers.
