Overview

The NEEWER S101-400W is a manual studio strobe that delivers 400Ws of flash power at a consistent 5600K color temperature, making it a reliable workhorse for product photography, portraits, still life, food, and commercial work. The GN65 guide number (measured at 1 meter, ISO 100) gives you flexibility to light subjects at varying distances and aperture settings. Flash power adjusts across a range from 1/8 to full power in fine increments, while flash duration spans 1/2000s to 1/800s — fast enough to capture most studio subjects sharply. Recycle time ranges from a quick 0.4 seconds at lower settings to 2.8 seconds at full output, and an integrated memory function saves your last-used settings for quick startup on repeat sessions.

A 150W modeling lamp with 9 brightness levels lets you preview lighting setups in real time before committing to the flash, a practical feature for dialing in shadow placement and highlight control. The strobe supports S1 and S2 optical slave modes for multi-light setups triggered by a master unit, and it's compatible with the NEEWER RT-16 radio trigger system for cable-free sync up to 30 meters. The standard Bowens mount opens up a vast selection of light modifiers — softboxes, umbrellas, beauty dishes, snoots, and reflectors — while an integrated umbrella socket and 180° tilt stand adapter provide additional positioning versatility. Optimized cooling fans and an enlarged air inlet keep the unit running safely through intensive shoots, tested to handle 260 consecutive full-power flashes without overheating.

Key Features

【400Ws Powerful Monolight】 NEEWER S101-400W is a professional studio monolight flash with 400Ws maximum power, 5600K consistent color temperature, GN65 high guide number (1m, ISO 100) for flexible flash distance and aperture settings—ideal for product, portrait, still life, food, commercial, and wedding photography

【Superior 150W Modeling Lamp】 Compact yet capable, the 150W modeling lamp has 9 brightness levels (L1–L9) and 7.0–10 (1/8–1/1) flash power adjustment to match ambient light conditions. 1/2000–1/800s flash duration and 0.4-2.8s recycling time help you capture every precious moment. The flash tube with a stable power output resists high heat, high voltage, deformation, and breakage. Memory function saves settings for the next time

【S1/S2 Optical Slave Modes】 It can work as a slave unit for diverse light effects, triggered by a manual master unit in S1 mode and a TTL master unit in S2 mode. It also works with the NEEWER RT-16 trigger receiver set (sold separately) for quick flash sync up to 1/200s within 100ft/30m

【Efficient Heat Dissipation】 The flash adopts optimized cooling fans and an enlarged air inlet for efficient heat dissipation. No overheating will occur even after 260 consecutive full power flashes for safe use and an extended lifespan

【Universal Bowens Mount】 To enrich light effects, the standard Bowens mount and umbrella socket can work with softboxes, photography umbrellas, reflectors, beauty dishes, snoots, and other light shapers. The metal stand mount adapter supports 180° tilt for free angle adjustment
