NANLUX has published a detailed explanation of its Nebula Light Engine system, the LED architecture at the heart of its current professional fixtures. The system consists of two solutions: the Nebula B4, a four-chip white light engine used in high-output fixtures like the Evoke 2400B, Evoke 5000B, and Matrix 2500B, and the Nebula C8, an eight-color engine with a 1,000K to 20,000K range that drives the Evoke 5C, Evoke 150C, Evoke 600C, and Matrix 2500C.
The term “light engine” refers to the specific arrangement and mix of LED chips inside a fixture, which determines its spectral output: which colors are present, how strong they are, and how they combine into white and colored light. That spectrum ultimately defines how subjects appear on camera, from skin tone rendering to the way fabrics and materials reflect light. We have already covered the Nebula C8 in depth when it was first unveiled, but NANLUX has now laid out how the complete system fits together across its fixture lineup, and it is worth taking a closer look at the reasoning behind it.
One system, two engines
The logic of the Nebula system is straightforward: fixtures that need maximum white-light output get the Nebula B4 White Light Engine, while fixtures that need color flexibility get the Nebula C8 Color Light Engine. According to NANLUX, both are built on the same core principles of accuracy, efficiency, and reliability, to match the right engine to each fixture’s role on set.
In practice, this means the Nebula B4 sits inside the high-output workhorses: the Evoke 2400B, which we reviewed in depth, the Evoke 5000B, and the Matrix 2500B. The Nebula C8, meanwhile, spans the full power range of NANLUX’s color fixtures, from the tiny Evoke 5C through the Evoke 150C and Evoke 600C up to the high-output Matrix 2500C.

The Nebula B4 is a tunable bi-color engine built from four types of white LEDs: Cool White+, Cool White−, Warm White+, and Warm White−. These four LED types correspond to four points on the chromaticity diagram, and the gamut they form covers the Planckian locus from 2,700K to 6,500K while also extending into the green and magenta regions above and below it.
This layout is what allows the B4 to generate white light across the full 2,700K to 6,500K range with green/magenta tint adjustment available throughout, useful for matching cameras or mixed practical sources. NANLUX points out that this addresses a real weakness of traditional bi-color designs, which often cannot correct green/magenta shifts properly across their whole range. Anyone who has tried to dial out a fluorescent green cast on a two-channel fixture will recognize the problem.

The efficiency argument for the B4 comes down to chip selection. Because the engine uses only white LEDs, NANLUX says it achieves higher luminous efficiency than systems that create white light by mixing colored LEDs, delivering more white-light output at the same power level. More of the electricity becomes light and less becomes heat inside the fixture, which matters most when a fixture like the Evoke 2400B is being pushed for maximum output on domestic power circuits.
The knock-on effects are practical rather than theoretical. A lower cooling load means the cooling system can be smaller and lighter, keeping the fixture more compact, and it helps the light maintain stable output during long stretches of high-power operation. That, according to the company, is why the Evoke 2400B, Evoke 5000B, and Matrix 2500B are positioned for large-scale matrix lighting setups where bright, consistent output over hours is the whole job.

On the color side, the Nebula C8 combines eight LED colors: Deep Red, Red, Amber, Lime, Green, Cyan, Blue, and Indigo. NANLUX describes it as the industry’s first eight-color light engine, with the mix designed to fill gaps in the spectrum that traditional color engines miss. The addition of Deep Red is what pushes the low end of the color temperature range down to 1,000K, for extremely warm candlelight-like tones, while the top end reaches 20,000K, well beyond typical daylight. Green/magenta adjustment is available across that entire span.

The company also highlights more continuous coverage in the red wavelength range, which it says translates into healthier skin tones with natural vibrancy and accurate texture, along with improved output in difficult colors like deep red and indigo. In terms of gamut, NANLUX claims about 82% coverage of the CIE 1931 color space, which it states is around 6% more than Rec. 2020 occupies within the visible gamut, and roughly 94% coverage of Rec. 2020 itself.

One detail worth highlighting is UV safety. Indigo LEDs can stray toward ultraviolet wavelengths, so the Nebula C8 also removes the ultraviolet wavelength from the indigo LED. This prevents potential UV exposure for talent and crew at the source, and it avoids unwanted UV-triggered fluorescence from costumes, props, and set materials, a subtle but real problem when certain fabrics or optical brighteners start glowing under a fixture. NANLUX notes that all NANLUX and NANLITE LED fixtures are designed not to emit ultraviolet light.
For the fixtures that carry the C8, this eight-channel architecture is what enables the range we have seen in practice: the Evoke 5C, which won a CineD Best-of-Show Award at NAB 2026, packs the same engine as the much larger Evoke 600C and Matrix 2500C, so a tiny hidden practical and a high-output key source can be matched precisely across a set. These fixtures handle subtle fill and natural white light as well as bold color effects and stylized atmospheres, all with the same wide green/magenta adjustment across the 1,000K to 20,000K range.
Looking ahead, NANLUX says it plans to continue exploring new possibilities in light engine technology and expanding what is possible with light for film and television production. More information on the Nebula system is available on the NANLUX website.
