100W S-Mount lighting in a backpack-sized body
The Godox RS100Bi and RS100R bring 100W-class output to a compact, cylindrical S-Mount lighting form factor aimed squarely at mobile production lighting. With the included high-efficiency lens reflector, the RS100Bi is rated at up to 28,600 lux at one meter at 5600K, putting it in the same output bracket as the mains-powered SL100Bi while shedding the need for a wall outlet. The RS100R full-color version trades some intensity for RGB flexibility, delivering 15,900 lux at one meter with the reflector at 5600K. Both fixtures scale up the integrated-power concept introduced with the RS60 series, but now with enough headroom to act as a plausible key light rather than just a practical or background source. Starting at USD 229 (approx. RM1,070) before tax, the RS100 line offers a relatively accessible entry point for location shooting equipment and small crews building multi-light kits.
Built-in battery and PD fast charging for location agility
For on-location crews, the RS100 series’ integrated battery and USB-C Power Delivery charging are central to their appeal. Godox quotes around 52 minutes of continuous full-output runtime, which aligns well with typical run-and-gun setups, interviews, and short b-roll sequences. Crucially, the fixtures support simultaneous charge-and-shoot operation, so teams can tether to a high-wattage PD brick or laptop charger and keep rolling. Charging from a 60W or higher PD source takes roughly two hours, and compatibility spans 18W to 140W chargers, simplifying power logistics for crews who already standardize on USB-C. The rear OLED display shows a runtime countdown alongside dimming and mode information, helping operators make informed calls about whether to roll, recharge or re-route power. For mobile production lighting, this combination of honest runtime, flexible charging, and clear feedback reduces the friction of working away from mains power.
Color control, dimming finesse and app-based operation
Beyond raw output, the RS100Bi and RS100R are tuned for precise, repeatable control demanded by professional mobile production lighting. Both units dim from 0.0% to 100.0% in 0.1% increments, with a true 0.0% floor that allows clean fade-outs without the abrupt final step many compact LED lights exhibit. Four selectable dimming curves—linear, S-curve, exponential and logarithmic—let gaffers match fixture response to narrative cues or practical gag lighting. The RS100Bi covers a 2,800K to 6,500K range with a claimed CRI and TLCI of 98, while the RS100R stretches from 1,800K to 10,000K and adds full RGB control, multiple FX presets and selectable Rec. 709 or DCI-P3 gamut targets. NFC tap-to-pair connects quickly to the Godox Light app for wireless control and firmware updates over Bluetooth, while an optional DMX-C2 adapter integrates the fixtures into wired DMX/RDM consoles for more complex setups.
Leveraging the S-Mount ecosystem for versatile setups
The RS100 series leans heavily on Godox’s S-Mount lighting ecosystem, turning each fixture into a chameleon for diverse shooting scenarios. The proprietary cylindrical mount supports lens reflectors, parabolic and rectangular softboxes, Lantern globes, the BeamLight S20 narrow-beam booster, LiteFlow modifiers, magnetic accessory kits, collapsible diffusion domes, parallel beam boosters, zoom lenses and the SP36/50K projection attachments. These ultra-compact projection units, significantly smaller than traditional options, transform the RS100 into a practical gobo projector for textured backgrounds, signage or stylized practicals in tight spaces. The rotating body and interchangeable lenses expand creative options without adding bulky hardware to a mobile kit. Godox’s launch imagery highlights multi-light setups mixing softboxes, lanterns and projection attachments, underscoring the RS100 not as a standalone light but as the core of a modular on-location system that can scale from solo shooters to small production teams.
A new baseline for location shooting equipment
By combining 100W-class output, integrated power and a mature S-Mount accessory ecosystem, the RS100Bi and RS100R redefine expectations for compact LED lights in mobile workflows. They occupy a strategic tier above the 60W RS-series while sitting below Godox’s SL and KNOWLED lines, giving content creators a flexible, cost-conscious path into multi-point lighting on the move. The ability to mount on standard 1/4-20 points, use the supplied AD-E2 bracket on light stands, and power from the same USB-C infrastructure as laptops and monitors all reduce friction for small crews and solo operators. While runtime at full tilt is finite, the honest specifications, runtime countdown, and charge-and-shoot support make planning straightforward. For many location shooters, the RS100 series may become the default choice when a backpack-friendly, S-Mount-capable key light is required without compromising on control or color fidelity.
