Ulanzi C01 COB Light 100W Bi-Color(Mini Bowens Mount Diffuser)

The Ulanzi C01 COB Light 100W Bi-Color is a compact COB light designed for videographers, photographers, streamers, and product photography. It offers up to 100 W of power, a continuously adjustable color temperature range of 2700–6500 K, and high color accuracy with a CRI of 96+ and a TLCI of 98+.

Thanks to its Mini Bowens mount, the light can be combined with compact modifiers, diffusers, and mounts. Its lightweight design, active cooling, and USB-C PD 3.0 power delivery make it a practical solution for both studio and on-the-go shooting.

The Ulanzi C01 is a small but powerful continuous light designed for situations where a strong, precise, and easily portable light source is needed. It’s suitable as a main light for talking-head videos, product photography, livestreaming, and tabletop shoots, as well as a fill light in a small studio.

Its 100 W output provides ample headroom even when using a diffuser. The light reaches up to 14,500 lux at a distance of 0.5 m at 6500 K and 100% brightness, so it can illuminate detailed product shots and portrait shots without the need for a large studio setup.

The 2,700–6,500 K range allows you to match the light to warm interior lighting or daylight. Brightness is continuously adjustable from 20% to 100%, so you can quickly find the right intensity without having to rearrange the entire scene.

High color accuracy with a CRI of 96+ and a TLCI of 98+ helps preserve natural skin tones and true-to-life product colors. Active cooling with a high-speed fan and a lightweight design ensures stable operation during extended shoots.

The Mini Bowens mount expands light-shaping options using compatible modifiers. The design with a 1/4" ARRI-style mounting point facilitates installation on a handle, stand, or mount depending on the specific shooting setup.
