The Accent B7c is an innovative RGBWW color mixing LED light bulb and the first product in Aputure’s new Accent line of practical LED fixtures. It stands out with a unique combination of features unmatched by any other luminaire. Utilizing the same advanced color mixing technology found in the Nova P300c, the B7c offers a broad color temperature range from 2,000K to 10,000K and delivers professional-level color accuracy. What makes this smart bulb especially groundbreaking is its built-in rechargeable lithium-polymer battery and onboard control buttons that allow direct adjustment of correlated color temperature (CCT) and brightness without needing an app.
Designed specifically with filmmakers in mind, the Accent B7c features a standard E26/E27 screw socket, making it compatible with a wide range of lamp fixtures worldwide. Its compact light bulb form factor enables seamless integration of programmable, color-mixing practical lighting into any scene, offering versatility and creative freedom. The B7c achieves cinema-grade color reproduction thanks to its high CRI and TLCI values of 95+ and 96+ respectively, and a tungsten spectral similarity index (SSI) score of 85, surpassing many industry-standard lights. Thanks to its unique RGBWW LED configuration, it can produce over 90% of the saturated colors within the Rec.2020 color space, making it highly capable for accurate and vibrant color effects.
Unlike typical consumer LED bulbs, the B7c includes stepless dimming from 0 to 100% with no flicker or color shift, even at high frame rates up to 1,000fps, ensuring smooth, professional-grade lighting. Its internal battery provides over 70 minutes of continuous operation at full power and can last more than 20 hours at minimum brightness, supporting multiple power modes—AC and battery-powered DC—allowing flexibility in any shooting environment. When powered by AC, the bulb remembers its last settings and functions like a traditional bulb, enabling natural on/off interactions for talent and crew. The aluminum metal housing paired with a toroidal diffusion design spreads light evenly while remaining completely stealthy on camera.
The Accent B7c also offers on-board control buttons for quick adjustments to brightness and CCT presets, enabling intuitive use without needing to connect to the Sidus Link app. However, when connected via Bluetooth to the Sidus Link app, the B7c unlocks a vast range of creative possibilities, including fine-tuning of CCT, brightness, color, and access to special lighting effects (FX) like Paparazzi, Fireworks, Faulty Bulb, Lightning, TV, Pulsing, Fire, Party, and Cop Car. Its compatibility with SidusPro FX further enhances its programmability, allowing complex, customizable lighting sequences that work in tandem with other Aputure fixtures. The built-in Sidus Mesh technology ensures reliable wireless control over distances up to 164 feet.
Despite its deceptively small 2.75-inch diameter size, the Accent B7c packs remarkable performance and versatility. Its wide color temperature range and RGB capabilities allow it to blend seamlessly with other light sources or provide dramatic, creative color accents. The high color accuracy ensures impeccable skin tones and true-to-life rendering. The smart bulb’s universal voltage support from 100 to 240V makes it suitable for use worldwide, and the integrated battery offers mobile flexibility for location shooting.
For users requiring multiple units, Aputure offers an 8-Light Charging Kit designed for indie filmmakers, rental houses, and owner-operators. This kit includes a durable hard-shell case capable of storing, protecting, and simultaneously charging up to eight B7c bulbs, simplifying logistics and ensuring readiness on set.
In summary, the Aputure Accent B7c is a 7W RGBWW LED smart bulb that combines professional color accuracy (CRI 95+, TLCI 96+, SSI tungsten 85), wide tunable white range (2,000K to 10,000K), smooth flicker-free dimming, extensive color and effect controls, and the flexibility of dual power modes in a compact, practical light bulb design. Its innovative features make it an indispensable tool for filmmakers seeking precise, versatile, and portable lighting solutions.
