The B7c 8-Light Kit comes with 8 Accent B7c RGBWW LED Bulbs with a Hard Shell Charging Case which stores & charges up to 8 B7c Bulbs. The Accent B7c is a battery-operated 7W RGBWW colour-mixing LED light bulb, and the first product in Aputure’s Accent family of “practical” LED lights built for filmmakers, with a unique combination of features no other light has. The B7c features a standard E26/27 lamp socket screw connector making it compatible with a wide variety of lamps anywhere in the world. Its light bulb form factor allows users to more naturally integrate programmable, colour-mixing, practical lighting into any scene. The Accent B7c matches the colour temperature range of the Nova P300c, Aputure’s most advanced colour mixing light, producing a wide colour temperature range of 2,000K-10,000K. And when combined with Sidus Link’s SourceMatch feature, it can match nearly any white light source. Unlike typical household LED bulbs, the Accent B7c uses cinema-grade LEDs to reproduce immaculate skin tones -- with impeccable CRI and TLCI values of 95+, and a tungsten SSI score of 85, outpacing industry-standard lights. Utilising Aputure’s unique RGBWW LED configuration, the B7c bulb is able to produce over 90% of the saturated colours in the Rec.2020 colour space, putting it on par with industry-standard lighting instruments. The Accent B7c like all Aputure products is made with filmmakers in mind. Unlike consumer LED smart bulbs, the B7c features 20KHz stepless dimming that remains completely flicker-free up to at least 1,000fps with no colour shift. It is also the first bulb designed for filmmakers to have a built-in battery, powering the B7c for over 70 minutes at full power, and over 20 hours as it approaches minimum brightness. The B7c’s unique internal battery allows the B7c to have multiple power supply modes: AC & Battery (DC). In AC power mode the B7c retains its last settings and turns on and off like a traditional light bulb, allowing for natural interactions with actors. The Accent B7c is the only LED smart bulb to feature on-board buttons for both brightness and CCT control, allowing users to adjust intensity and CCT presets in a few simple clicks, without even connecting it to the Sidus Link app. Using built-in Sidus Mesh technology, the B7c can also be controlled wirelessly via a smartphone or iPad using the Sidus Link app, allowing filmmakers to fine-tune CCT, brightness, colour, and FX, as well as use SourceMatch and ColourPicker modes to match nearly any colour.
