Overview

The Neewer Q4 400Ws Studio Flash is an IF Design Award-winning strobe that bridges the gap between studio power and on-location portability. At just 4.94 pounds and measuring 7.28 by 6.06 by 8.35 inches, it is compact enough to pack into a gear bag for outdoor shoots while still delivering the 400Ws of output needed for overpowering sunlight or filling large modifiers. The strobe supports three flash modes — TTL for automated exposure, Manual for precise control across its full power range, and Multi (stroboscopic) mode with rates up to 199Hz and 100 flashes per burst for creative motion effects. High-speed sync at 1/8000s means you can shoot wide open in bright conditions without neutral density filters, and flash duration as fast as 1/10989s freezes even the fastest action.

The included QPRO-C wireless trigger operates on a 2.4GHz system with 5 groups, 32 channels, and 99 IDs, providing reliable communication up to 328 feet — more than enough for most studio and event setups. The built-in 30W LED modeling lamp at 5600K with a CRI of 95+ gives you accurate previews of your lighting before firing the flash. A standard Bowens mount connects the Q4 to the vast ecosystem of compatible modifiers, from softboxes to beauty dishes. The 21.6V/2800mAh lithium battery is field-swappable for extended shoots and charges via the included DC adapter in about 3.5 hours. Neewer has also included USB-C firmware update capability, ensuring the strobe can receive compatibility and feature updates over time. The complete package arrives with a wireless trigger, standard reflector, lithium battery, top handle, power adapter, and a fitted carrying case.
