Reference price: 37,000 yen I purchased this new but am selling it because I won't be using it. 【400Ws Monolight & 150W Modeling Lamp】The NEEWER S101-400W PRO studio monolight for strobe light photography features a high output of 400Ws, a GN65 guide number (1m, ISO100), and an upgraded 150W LED modeling lamp (2600K) with brightness levels from 10% to 100%. It is suitable for commercial, portrait, wedding, and still life photography. The flash duration of 1/100 to 1/1000 seconds and a recycle time of 0.1 to 2.4 seconds are ideal for shooting moving subjects and continuous shooting. 【Powerful and Stable Flash Output】The 5600K±200K cool daylight ensures high color fidelity and accurate color reproduction. The flash tube is resistant to high heat and high voltage, providing stable performance and continuous full-power flashes (flash power adjustment: 4.0-10 (1/64-1/1)). The HD LCD screen provides visual reference and stores data for quick flash setup. 【2.4G Wireless Q System & S1/S2 Mode】The S101-400W PRO operates with a 2.4G 16-channel trigger, allowing for high-speed sync of 1/200 second within 100ft/30m when set to the same channel. The S101-400W PRO also works with the QPRO trigger (sold separately), with 1-99 wireless IDs and 32 channels for faster synchronization and better anti-interference capabilities. In S1 mode, it can be triggered by a manual master unit, and in S2 mode, it can be triggered by a TTL master unit. 【Efficient and Quiet Heat Dissipation】The newly upgraded heat dissipation system adopts a silent cooling fan and an excellent radiator, effectively reducing the operating temperature, extending the life of the monolight, creating a quiet shooting environment, and preventing overheating after 260 consecutive full-power flashes. 【Versatile Bowens Mount & Umbrella Socket】The standard Bowens mount is compatible with various light modifiers such as softboxes, reflectors, beauty dishes, and snoots, enabling creative flash effects. The built-in umbrella socket can fix a photography umbrella and supports 180° angle adjustment for flexible light positioning.
