SmallRig RC 100B COB Video Light with Handle - Portable Bi-Color 100W

In this review the SmallRig RC 100B stands out as a compact, travel-ready continuous light aimed at run-and-gun creators and small studio shooters who need accurate, powerful daylight-adjustable output in a tiny package. The single biggest reason to buy is its combination of high color fidelity and surprisingly strong output for its size, making it useful for mobile interviews, product close-ups, and on-location photography when space and weight matter.

Key Features

• Ultra-portable build: The aluminum body weighs about 700 grams and measures 115 x 95 x 95mm, so it fits easily in a camera bag and is convenient for mobile shoots.
• Wide color range: 2700K to 6500K tuning covers warm to daylight tones, letting users match ambient light or create specific moods.
• High color accuracy: With CRI 97+ and TLCI 98+, skin tones and practical colors render naturally on camera for reliable results.
• Strong output options: It delivers 4,610 lux bare and up to 20,100 lux using the hyper reflector at 1m/5600K for punchy illumination when needed.
• Flexible power: USB-C PD support and direct V-mount/NP-F battery plate options give multiple on-location power choices.
• Low-noise cooling: Intelligent thermal control and a quiet fan (about 26dB at 1m, 18dB in ECO) avoid disturbing audio during recording.

Who It's For

The RC 100B is best for mobile content creators, vloggers, product photographers, and small studio operators who need a lightweight, high-CRI light that delivers controllable color temperature and strong output without a bulky kit. Its handle and compact footprint make it especially suited for travel and handheld setups where space is limited.

It may not be the right choice for large studio rigs that require native Bowens mounting or integrated softbox compatibility out of the box; users who need heavy modifiers should either buy the dedicated smallrig softboxes or the Bowens adapter separately or choose a larger fixture that includes Bowens compatibility.

Pros & Cons

Pros

• Excellent color rendering (CRI 97+, TLCI 98+) for natural-looking skin tones.
• Very portable and lightweight, easy to carry for travel and run-and-gun shoots.
• Multiple power options including USB-C PD and V-mount/NP-F compatibility for long field use.
• High maximum output with reflector for demanding lighting situations.

Cons

• Not compatible with Bowens mount accessories without buying a separate adapter or dedicated softbox, which limits modifier options out of the box.
• Unit sold without batteries, so plan on purchasing compatible V-mount or NP-F batteries separately for untethered use.

Our Verdict

The SmallRig RC 100B is a smart buy for photographers and videographers who prioritize portability and color fidelity without sacrificing output. It offers strong, tunable light and versatile powering options, making it good value for travel kits and small studios, provided buyers budget for batteries or optional adapters if they need specific modifiers.

Frequently Asked Questions

Does the light come with batteries?
No, the RC 100B is sold without batteries; compatible V-mount or NP-F batteries are recommended for portable use.

Can I use softboxes directly on the unit?
The RC 100B is not Bowens compatible by default; use SmallRig dedicated softboxes or buy the Bowens adapter separately to attach standard modifiers.

How quiet is the fan during recording?
The intelligent cooling keeps noise low at about 26 dB at 1 m and around 18 dB in ECO mode, so it should not interfere with most on-camera audio.
