Aputure Accent B7c RGBWW LED Light Bulb

Aputure Accent B7c RGBWW LED Light Bulb

The Accent B7c is an RGBWW color mixing LED light bulb and the first product in Aputure’s new Accent line of practical LED fixtures. It uses the same advanced color mixing technology as the Nova P300c, offering a fully tunable color temperature range from 2,000K to 10,000K and professional-level color reproduction. The bulb achieves an SSI score as high as 85 in tungsten, ensuring accurate and high-quality lighting.

Despite its low 7W LED output, the B7c produces light equivalent to a 50W household tungsten bulb. It is the first color mixing smart bulb to feature a built-in lithium-polymer battery, enabling over 70 minutes of operation at maximum brightness. This makes it highly versatile for various shooting scenarios without the need for constant power supply.

To improve on-set workflow efficiency, the B7c includes on-board control buttons for quick toggling between CCT presets and brightness adjustments. Additionally, it supports wireless control via the Sidus Link Bluetooth app, allowing users to manage multiple bulbs from a smartphone or tablet and access fine-tunable color capabilities.
