The Aputure 300d Mark II is a significant evolution of the original 300d, offering notable improvements in brightness, durability, intelligence, and overall design while retaining the familiar universal Bowens mount and an exceptional TLCI rating of 97. This model introduces a quieter lamp head that is 20% brighter and more robust, featuring an all-in-one silent control box equipped with eight built-in lighting effects and DMX-512 compatibility. Notably, it is the first Aputure light to integrate Sidus Link Mobile App control, alongside a new quick-release Lightning Clamp that enhances setup speed and versatility.
Built on the solid foundation of the popular LS C300d, the LS C300d II Daylight LED Monolight boosts output by 20%, delivering refined features and advanced connectivity options. Utilizing Chip on Board (COB) technology, it produces a precise 5600K color temperature with a maximum power consumption of just 350W, yet generates up to 45,000 lux of light measured at 3.3 feet with an efficient reflector. Its high color accuracy is reflected in its CRI and TLCI ratings of 96+, ensuring faithful color rendering. The fixture’s ballast/controller is separate from the lamp body, making the head lighter and more compact. It also employs flexible dimming options including linear, logarithmic, exponential, and S-curve modes from 0 to 100%, allowing precise light control in any environment. A quick-release plate connects to the included clamp for easy mounting on light stands, effectively distributing the weight for convenience and stability.
The 300d Mark II’s performance is matched by its rugged and thoughtfully engineered design. Its all-aluminum body undergoes multiple fabrication steps for durability, while the reflector and accessory mount utilize the widely adopted Bowens S-Type standard. The light comes with a wireless remote control capable of managing on/off and dimming functions up to 328 feet away. Additionally, Aputure’s Bluetooth-enabled Sidus Link App allows wireless adjustments of all lighting functions and creative effects such as lightning, pulse, flash, and explosion. Ideal for sound-sensitive settings, the fixture features a highly efficient fan that can be completely switched off for silent operation. The light supports worldwide power use with a 110-240V AC supply, and for field work, it includes dual battery plates compatible with V-Mount batteries to enable external power. The package also includes a power cable, DMX cable, wireless remote, clamp, and a robust carrying case designed to withstand up to 220 pounds, protecting the light during transport and on location.
Aputure first disrupted the industry with the original 300d by offering a powerful, compact LED fixture with easy modification options. The 300d Mark II answers user feedback by enhancing brightness by 20%, improving durability, portability, and intelligence, while maintaining the same lightweight aircraft aluminum form factor. The updated yoke offers 360° rotation and incorporates a handbrake locking mechanism borrowed from the 120d Mark II, enabling secure positioning with any light modifier.
One of the standout features of the 300d Mark II is its all-new hyper-efficient 55° reflector, which slightly narrows the beam from the original 60° and optimizes the inner shape and coating. This redesign increases light output by more than three times compared to the original reflector, significantly boosting performance. The control box itself has been fully redesigned to be completely silent thanks to Aputure’s fan-less heat sink technology. Made from durable aluminum alloy and featuring a concealed antenna and military-grade paracord strap, the control box is built to endure the demands of professional film sets. It also introduces Aputure’s quick-release plate and clamp system, allowing secure attachment to stands, trusses, or speed rails.
Power solutions on the 300d Mark II are flexible and cater to indie filmmakers and professionals alike. The fixture can deliver full output using two high-capacity V-Mount or Gold Mount batteries, but it also supports single battery operation at up to half power, maximizing portability. A sturdy 19.7-foot Neutrik cable provides reliable power connection without needing additional power accessories.
Control features have been greatly enhanced, with eight built-in lighting effects including paparazzi, spark, lightning, faulty bulb, TV, pulse, flash, and explosion, with the potential for future additions through firmware updates. A trigger button on the control box allows instant activation of effects. The light supports smooth 0 to 100% stepless dimming across four customizable dimming curves, allowing it to be used in subtle low-light conditions or in bright environments to overpower sunlight. The 300d Mark II also includes a Studio Mode, enabling immediate light activation and control upon power-up, making it ideal for complex DMX lighting grids.
Additional control options extend beyond the control wheel to include DMX512 compatibility and a 2.4 GHz wireless remote with an FX toggle button. The 300d Mark II is also the first Aputure fixture to support Bluetooth 5.0 via the Sidus Link App, which uses Bluetooth SIG mesh networking technology to control multiple lights over distances of up to 1,300 feet by linking lights up to 262 feet apart. The app unlocks full control over all light functions, preset management, fine-tuning, lighting effects triggering, and firmware updates directly from a smartphone or tablet.
The newly designed carrying case reflects Aputure’s commitment to professional users, featuring durable walls with a soft interior lining capable of supporting up to 220 pounds. The exterior bottom is made from slash-proof, easy-to-clean material, ensuring reliable protection and a convenient seat on set.
In summary, powered by user feedback and advanced LED technology, the 300d Mark II delivers 20% more brightness, enhanced durability, greater portability, and smarter control than its predecessor. Paired with the Fresnel 2X, it can reach up to 90,000 lux, rivaling the brightness of a 575W HMI. Its comprehensive dimming options, extensive wireless controls, and silent operation make it a versatile and powerful lighting solution for filmmakers and photographers alike.
