Technical Details
The DS1 system uses 12 interchangeable LED modules, each with a power of 15 watts, while the DS3 model reaches up to 1080 watts with 72 modules. The color temperature can be continuously adjusted between 2700K and 6500K, with a CRI value of over 95. Each module features individual RGBW LEDs, enabling precise color mixing. The lights operate with 14.4V battery systems (V-Mount or Gold Mount) and offer DMX512 control as well as app-based wireless control via Bluetooth. The spherical arrangement of the modules creates a 360° beam angle without hard shadows.
History & Development
Digital Sputnik was founded in Riga in 2014 by Aigars Bišs, after he, as a DoP, recognized the limitations of conventional LED panels. The first DS1 model was launched in 2015, establishing the concept of the modular spherical light. In 2017, the more powerful DS3 system followed, and in 2019, the compact DS6 model for mobile applications. The development focused on combining maximum portability with professional light quality, which was only available separately in traditional studio systems.
Practical Application in Film
Digital Sputnik lights have been used in productions such as "The Queen's Gambit" (2020) for atmospheric background lighting and in numerous music videos for dynamic color effects. The 360° emission is particularly suitable for car rigs, as one light covers multiple lighting directions. In confined shooting spaces, they function as space-saving key or fill lights. Battery operation allows for quick setups without a power source, while app control permits simultaneous control of multiple units. Disadvantages become apparent in directed lighting, as the omnidirectional emission requires additional baffling.
Comparison & Alternatives
Unlike flat LED panels such as Arri SkyPanel or Litepanels, Digital Sputnik lights produce point light sources with soft shadow rendering. Astera Tubes offer similar portability but a linear rather than spherical light distribution. Modern alternatives like the Nanlite Forza series or Godox VL systems focus on higher light output with directed emission. Digital Sputnik is optimally suited for mobile shoots with limited equipment volume, while traditional Fresnel or LED panel setups enable more precise light control under controlled studio conditions.
