The ZHIYUN MOLUS B300 features a continuously adjustable color temperature range from 2700K to 6500K, enabling photographers and filmmakers to reproduce warm tungsten-style illumination, balanced neutral white light and cooler daylight conditions with a single fixture. This flexibility allows the spotlight to match existing light sources, adapt to mixed lighting environments and establish consistent visual atmospheres across different scenes. The fixture achieves a color rendering index of CRI 95 or higher and a TLCI rating of at least 97, supporting accurate reproduction of skin tones, product colors and subtle material textures. Additional color quality specifications include an average TM-30 Rf value of 94, an average TM-30 Rg value of 101 and a CQS rating of at least 94, reflecting dependable color fidelity and naturally balanced saturation. Brightness can be adjusted smoothly from 0% to 100%, allowing precise control over exposure and lighting ratios. At 5500K, the MOLUS B300 produces approximately 2130 lux at a distance of 3 m without a reflector and 5530 lux with the standard reflector installed. At 5 m, the corresponding values are approximately 732 lux and 1730 lux. The combination of flexible color temperature adjustment, accurate color reproduction and substantial output makes the MOLUS B300 particularly valuable for professional portrait photography, commercial product presentations, interviews and cinematic productions where consistent white-light quality is essential.

Integrated power supply for efficient production workflows

One of the defining advantages of the ZHIYUN MOLUS B300 is its integrated power supply, which eliminates the need for a separate external adapter or ballast. Unlike conventional high-output studio lights that require additional power units and connecting cables, the MOLUS B300 operates directly from a single AC power cable. This streamlined arrangement reduces setup complexity, minimizes cable clutter and makes it easier to reposition the fixture during production. The light supports an input voltage of 100–240 V AC at 50–60 Hz, allowing operation with compatible electrical systems in different regions. Its integrated design is particularly useful for mobile production teams, rental studios and photographers who frequently change lighting configurations. The supplied 4.5 m power cable provides additional flexibility when positioning the fixture on lighting stands or arranging equipment around a studio environment. Despite incorporating its power supply and active cooling system within the same housing, the MOLUS B300 measures approximately 245 × 190 × 159 mm with its mounting bracket. Its net weight without the reflector is approximately 2.57 kg, making it practical to transport and install relative to its lighting capabilities. By integrating power management directly into the fixture, ZHIYUN provides a cleaner and more efficient approach to professional studio illumination without sacrificing the performance expected from a 300 W spotlight.

Advanced DynaVort cooling for consistent performance

The ZHIYUN MOLUS B300 incorporates the advanced DynaVort Cooling System MK V, an active thermal management solution designed to maintain reliable performance during demanding lighting applications. High-output COB LED technology generates considerable heat, particularly during extended recording sessions and continuous operation at high brightness levels. To manage this thermal load, the MOLUS B series employs an innovative three-sided cooling structure with electronically controlled airflow and pressure monitoring. Two pressure sensors help optimize air circulation, reduce turbulence and improve heat dissipation efficiency within the compact housing. This carefully engineered cooling arrangement allows the fixture to maintain substantial output without requiring an excessively large lighting enclosure. The system operates automatically, allowing photographers and lighting technicians to concentrate on composition and exposure rather than manually adjusting cooling settings. The MOLUS B300 is designed for operation in ambient temperatures ranging from −10°C to 40°C, making it suitable for a variety of indoor and appropriately protected outdoor production environments. Efficient thermal management supports stable illumination during interviews, commercial filming, product photography and extended studio sessions. By combining intelligent cooling technology with an integrated power supply, the MOLUS B300 delivers professional performance in a practical and space-efficient design.

Universal Bowens mount and versatile light shaping

The ZHIYUN MOLUS B300 features a standard Bowens accessory mount, providing compatibility with a broad range of professional lighting modifiers and allowing creators to shape illumination according to the requirements of each production. Compatible accessories include softboxes, reflectors, beauty dishes, snoots and lantern-style diffusers, enabling the fixture to produce concentrated directional light, soft portrait illumination or broad diffused coverage. The supplied standard reflector focuses the light output and increases illuminance to approximately 63,200 lux at 1 m when the color temperature is set to 5500K. This concentrated output is particularly useful when the light must be positioned farther from the subject or when working with larger scenes. For softer and more flattering illumination, compatible diffusion modifiers can be used to create smooth transitions between highlights and shadows, making the fixture suitable for interviews, portraits and beauty productions. More directional modifiers can emphasize product details, create dramatic contrast or selectively illuminate specific areas of a scene. An adjustable mounting bracket allows the lighting angle to be changed and securely fixed on a compatible lighting stand. The combination of substantial power, compact construction and universal modifier compatibility makes the MOLUS B300 a flexible choice for both simple lighting setups and sophisticated multi-light productions.

Intuitive operation and intelligent wireless control

The ZHIYUN MOLUS B300 combines convenient physical controls with wireless operation through the ZY Vega mobile application, providing flexible adjustment of essential lighting parameters. Integrated adjustment dials allow users to control brightness and color temperature directly on the fixture without navigating complicated menus. Preset shortcuts provide quick access to five brightness levels from 20% to 100% and five commonly used color temperature settings, while continuous adjustment remains available for precise control. Bluetooth connectivity enables compatible smartphones to communicate with the light through the ZY Vega application, allowing remote changes when the fixture is mounted overhead, positioned behind diffusion materials or installed in locations that are difficult to reach during recording. The MOLUS B300 also supports the optional ZHIYUN K1 controller, offering an additional method of adjusting lighting parameters without accessing the fixture itself. Wireless control is particularly useful for coordinating multiple compatible ZHIYUN lights in a studio or production environment. The fixture also includes 13 built-in lighting effects that can be used to create dynamic visual atmospheres, simulate changing environmental illumination and introduce cinematic lighting variations without additional effects equipment. Combining accessible onboard controls, smartphone connectivity and optional external adjustment, the MOLUS B300 helps streamline lighting operations for individual creators and professional production teams.
