Aputure APM021XA11 Amaran 100d S LED Video Light

The Aputure Amaran 100d S is a 100W daylight-balanced LED monolight built around two metrics that matter most in professional video and photography lighting: CRI 96+ and TLCI 99+. The CRI score reflects how accurately the light renders colors as perceived by human vision; the TLCI score addresses how camera sensors specifically respond to spectral output. At TLCI 99+, the 100d S effectively removes the fixture as a source of color error in the recording chain. The 5600K color temperature aligns with noon daylight, enabling seamless blending with natural window light or strobe-balanced ambient setups without gel correction. SSI (D56) of 86+ confirms high spectral similarity to a D56 reference daylight source — meaningful for color-critical beauty and commercial work where consistency across sessions is non-negotiable.

The built-in Bowens mount gives the 100d S immediate access to the most widely supported modifier ecosystem in studio lighting — from large octaboxes to Fresnel adapters — without proprietary adapter purchases. Sidus Mesh wireless technology enables multi-light coordination and intensity adjustment from the Sidus Link app at up to 100m, covering large studio and location environments from a single device. The sub-25dB fan operation keeps the fixture below the ambient noise floor of most interview and studio recording environments. Optional DC 48V battery input expands the fixture to off-grid location use, though the battery must be purchased separately. For studio photographers, documentary filmmakers, and commercial video crews who need reliable, broadcast-accurate daylight output with maximum modifier flexibility, the Amaran 100d S performs well above its price point.
