The Aputure 300d Mark II is a powerful daylight-balanced LED monolight built for filmmakers, photographers, and content creators who need bright, reliable, portable illumination on set or on location. Delivering up to 350 watts of output at a color temperature of 5500K, it produces a punchy, focused beam that rivals traditional HMI fixtures while remaining far more compact and energy efficient. The bowens-mount head accepts a wide range of modifiers, including softboxes, reflectors, and the signature Aputure Fresnel, giving users tremendous creative control over spread, hardness, and shadow quality. Its bare-bulb output rating of over 15,000 lux at three feet makes it one of the most potent single-source LEDs in its class, suitable for overpowering sunlight outdoors or lighting large interior spaces with ease. Control and connectivity are central to the 300d Mark II's design. The included Aputure Wireless Remote (2.4G) allows users to adjust brightness and, in this updated version, dim smoothly through a wider range without color shift, addressing a common complaint from the original 300d. The light also supports Sidus Link app control via Bluetooth, letting operators manage intensity, color temperature effects, and special lighting modes like paparazzi, strobe, TV flicker, and lightning directly from a smartphone. This makes it easy to integrate the fixture into complex multi-light setups or run it remotely when mounted on a stand out of easy reach, such as high above a set for a bounced or diffused key light. Built with a rugged aluminum housing and an efficient fan-cooling system, the 300d Mark II is designed to withstand the rigors of professional production environments, from studio soundstages to demanding outdoor shoots. It can be powered via standard AC or through V-mount batteries for full location flexibility, and it ships with a durable carrying case for transport between jobs. The fixture's flicker-free performance ensures clean results even when shooting at high frame rates for slow motion, a critical feature for cinematographers. Combined with its high CRI and TLCI ratings for accurate color rendition, the Aputure 300d Mark II remains a favored workhorse LED for video production teams, wedding cinematographers, and photo studios seeking a dependable, high-output key light.
Customer reviews
Been using this as my main key light for two years now. The output is insane for the size, and the app control lets me dial exposure from behind camera without touching the head. Worth every penny.
Great light, punches through diffusion easily and color rendering is excellent. Only gripe is the head and ballast combo adds weight to my kit when I'm traveling light.
Switching from the older Aputure mount to Bowens made my life so much easier. I can throw any softbox or grid on this thing. Fan noise is minimal unless you're cranking it to 100%.
Reliable daylight source, CRI numbers hold up in post. App occasionally drops connection when I'm running three lights at once but otherwise solid performance.
We have four of these in our rental inventory and they get booked constantly. Clients love the output-to-size ratio and the included Light Dome softbox is genuinely useful.
