LiteMat Spectrum is a variable Color Temperature LED panel by LiteGear, offering stepless adjustment from 2700K to 6500K.
Technical Details
LiteMat Spectrum Panels are available in four standard sizes: LiteMat 1 (152×152mm), LiteMat 2S (305×305mm), LiteMat 4 (610×305mm), and LiteMat 8 (610×610mm). The lights achieve a CRI of at least 95 and a luminous efficacy between 2,800 and 22,400 lumens, depending on the model size. Power consumption varies from 40W (LiteMat 1) to 320W (LiteMat 8). Each panel contains warm white and cool white LEDs, whose mixing ratio can be controlled via DMX512 or the included controller interface. The panels operate at 24V DC voltage and can be powered by V-mount batteries or a power supply.
History & Development
LiteGear introduced the first LiteMat systems in 2011, initially with a fixed color temperature. The Spectrum variant with variable color temperature debuted in 2014 in response to the growing demand for tunable LED systems on set. In 2017, the integration of plus/minus green control followed for precise adjustment to different camera characteristics. The current generation from 2020 offers improved color rendering and reduced heat development through optimized LED chips.
Practical Use in Film
LiteMat Spectrum panels are particularly suitable for hidden light sources in confined spaces where conventional Fresnel fixtures cannot be positioned. In "The Revenant" (2015), cinematographer Emmanuel Lubezki used LiteMat arrays for seamless adaptation to changing daylight during available light sequences. The flat design allows them to be hidden behind furniture or integrated into ceiling panels. Common applications include eye lights for close-ups, uniform illumination of green screen areas, and as practical lights that function as part of the scenery.
Comparison & Alternatives
Compared to conventional Kino Flos, LiteMat Spectrum offers significantly more uniform light distribution without visible tube segmentation. ARRI SkyPanel S30/S60 represent more powerful alternatives but are considerably bulkier. Aputure Nova P300C competes in a similar form factor but achieves lower CRI values. For pure area lighting without color variability, classic Kino Flo systems remain more cost-effective, while LiteMat Spectrum excels when frequent color temperature changes are required without filter swaps.
