What CRI ratings do professional bi-colour lights achieve?

Professional bi-colour LED lights commonly advertise CRI values above 95, while the best fixtures can approach 98 or 99. But the number alone does not tell the whole story. A high CRI is a useful indication of colour quality, but professional cinematographers and photographers should also consider TLCI, individual colour samples such as R9, spectral consistency and, crucially for a bi-colour fixture, whether that performance remains stable across the entire CCT range.

At the top end of professional lighting, small differences become increasingly important. A fixture rated CRI 95 may already be perfectly usable for many productions, while a carefully engineered source approaching CRI 99 can provide greater confidence when reproducing skin tones, fabrics, cosmetics, artwork and product colours.

Maxima fixtures are designed around this colour-critical philosophy. Products such as Maxima Rapida, Maxima Spectra and Maxima Furiosa combine adjustable white light with a measured CRI of 98.6 and TLCI of 100, while daylight-focused fixtures such as Maxima 6 demonstrate what can be achieved when a source is optimised around one extremely accurate daylight spectrum.

What CRI ratings do professional LED lights typically achieve?

Most serious professional cinema and photography LEDs today fall somewhere around CRI 95 to 99.

A useful general interpretation is:

• Below CRI 90: generally unsuitable for colour-critical professional photography or cinematography.
• CRI 90–94: usable for many general lighting applications, but less desirable for demanding camera work.
• CRI 95–97: a strong professional level suitable for a wide range of photographic and video applications.
• CRI 98 and above: exceptional colour rendering, particularly valuable for skin tones, fashion, commercial photography, product work and colour-critical cinematography.

These ranges should not be treated as rigid industry classifications. CRI is a measurement, not a certification of whether a fixture is “professional”. But it is a useful first filter when evaluating the colour performance of a light.

What does CRI actually measure?

CRI stands for Colour Rendering Index. It compares how a light source renders a group of standardised colour samples against an appropriate reference illuminant at approximately the same colour temperature.

The familiar CRI number usually refers to Ra, the average result across the first eight test colour samples.

A score approaching 100 means those colours are rendered very similarly to how they would appear under the reference illuminant.

This is useful because two lights can both measure 5,600K and still reproduce objects differently. Colour temperature describes the general warm-to-cool character of white light. CRI attempts to describe how faithfully colours within that light are reproduced.

That distinction becomes extremely important with modern LED fixtures.

Is CRI 95 good enough for professional cinematography?

Yes. A genuine CRI above 95 is generally very good and can be entirely appropriate for professional cinema, photography and television production.

However, once the work becomes particularly colour-critical, there is value in going further.

Beauty photography, cosmetics, fashion, reproduction work, food, artwork and high-end commercial photography can expose small spectral deficiencies very quickly. The same applies to cinematography where multiple cameras and fixtures must remain visually consistent across a large production.

In these circumstances, a fixture approaching CRI 99 and supported by strong TLCI and spectral measurements gives the crew a cleaner starting point.

The advantage is not that CRI 95 suddenly produces “bad” colour. It is that higher-quality sources reduce the number of variables the cinematographer, photographer and colourist need to manage.

Why is CRI particularly important with bi-colour lighting?

A professional bi-colour fixture has a more complicated task than simply producing accurate light at one fixed colour temperature.

It must remain accurate while moving through a wide range of white points.

A typical adjustable-white fixture uses warm and cool LED emitters whose contribution changes as the selected colour temperature changes. The engineering challenge is therefore not simply achieving good colour at 3,200K and good colour at 5,600K.

The fixture also needs to behave correctly at intermediate values such as:

• 3,600K
• 4,000K
• 4,300K
• 4,800K
• 5,200K

These intermediate temperatures are frequently where professional bi-colour lighting is most useful, because real locations rarely fit perfectly into the traditional tungsten-versus-daylight distinction.

A well-engineered fixture should therefore maintain excellent colour reproduction throughout its usable range rather than offering impressive specifications only at one favourable measurement point.

Does a CRI of 98 automatically mean a light is better than one rated 95?

Not necessarily.

CRI is valuable, but it compresses a complicated spectral behaviour into one convenient number.

Two fixtures can both advertise CRI 98 and still render some materials differently because their spectral power distributions are different.

This is why professional evaluation should consider several factors together:

• CRI Ra: the familiar average colour-rendering score.
• R9: an additional saturated-red test sample that is especially relevant to skin tones and many natural materials.
• TLCI: a measurement designed to evaluate light sources in relation to camera imaging systems.
• Spectral Power Distribution: the actual distribution of energy across visible wavelengths.
• White-point accuracy: whether the fixture introduces unwanted green or magenta deviation.
• CCT consistency: whether the displayed Kelvin setting corresponds predictably to the emitted light.
• Dimming consistency: whether colour remains stable as output changes.

The best professional fixtures perform well across all of these areas rather than optimising for a single headline specification.

Why is R9 important if a fixture already has a high CRI?

The standard CRI Ra value does not include the saturated red sample known as R9 in its average.

This matters because reds are extremely important photographically.

Human skin contains significant red information. So do cosmetics, food, wood, textiles, flowers and many commercial products.

A fixture can therefore produce a respectable overall CRI while reproducing deep reds less accurately than expected.

For portrait, beauty and fashion work in particular, looking beyond the headline CRI number can provide a much better understanding of how the light will actually behave on camera.

What is the difference between CRI and TLCI?

CRI and TLCI approach colour quality from different perspectives.

CRI was developed to evaluate colour rendering relative to human visual perception and reference illuminants.

TLCI, or Television Lighting Consistency Index, was developed specifically with camera imaging systems and television production in mind.

That makes TLCI particularly relevant to cinematographers and videographers.

A light can appear perfectly acceptable to the human eye while interacting less favourably with a camera’s red, green and blue sensor responses. TLCI attempts to estimate how much correction would be needed to obtain acceptable colour reproduction through a camera system.

A value approaching TLCI 100 therefore indicates exceptionally camera-friendly spectral behaviour.

For professional filmmaking, looking at CRI and TLCI together provides more useful information than relying on either score alone.

Why can two lights with the same CRI look different on camera?

Because CRI is an average measurement rather than a complete description of the spectrum.

Imagine two fixtures that both achieve CRI 97.

One may reproduce most colours extremely accurately but have a slight weakness in saturated red. Another may render red beautifully but behave differently in cyan or another region of the visible spectrum.

The final average can still be similar.

Modern digital cameras complicate this further because different sensor designs have different spectral sensitivities. The same LED source may therefore interact slightly differently with a Sony, ARRI, RED, Canon or Blackmagic camera.

This is why demanding productions often combine manufacturer specifications with practical tests using:

• skin tones
• colour charts
• neutral greys
• difficult fabrics
• saturated objects
• the actual camera system intended for production

Does the CRI of a bi-colour light change with colour temperature?

It can.

The warm and cool channels inside a bi-colour fixture have different spectral characteristics. As their relative contribution changes, the combined spectrum changes too.

On a poorly engineered fixture, this can produce noticeably different colour rendering at different CCT settings.

A light might perform well at 5,600K but develop a slight green deviation or weaker colour reproduction around 4,200K.

Professional fixture design attempts to minimise this behaviour through careful LED selection, binning, driver electronics, thermal management and calibration.

This is why a specification measured only at one colour temperature should not automatically be assumed to describe the entire bi-colour range.

Is a daylight-only LED potentially more colour accurate than a bi-colour fixture?

It can be, because the engineering problem is different.

A daylight-only fixture does not need to create many different white points. Its entire optical, electronic and LED architecture can be optimised around one specific daylight spectrum.

The Maxima 6 is a useful example within the Maxima family.

Unlike Rapida, Spectra and Furiosa, Maxima 6 is a dedicated daylight fixture. Instead of prioritising adjustable colour temperature, it concentrates its performance around a highly accurate daylight source.

This can be extremely attractive in studio photography, product work, fashion, reproduction photography or controlled cinema environments where daylight is the established reference and there is no need to move continuously between warm and cool white.

The trade-off is straightforward:

A daylight-only fixture sacrifices CCT flexibility in exchange for specialisation around one defined white point.

When is bi-colour more useful than maximum fixed-colour accuracy?

On location, flexibility can be just as important as laboratory-level optimisation around a single spectrum.

Imagine beginning an interview beside a large daylight window at approximately 5,600K, moving into an interior with warmer practicals, and continuing production as daylight gradually changes during the afternoon.

A bi-colour fixture allows the lighting crew to adapt quickly without adding correction gels or swapping the key light entirely.

This is the environment for which fixtures such as Maxima Rapida, Maxima Spectra and Maxima Furiosa are designed.

The goal is not simply to provide multiple Kelvin values. It is to provide those values while maintaining professional colour quality across the range.

What CRI should you look for when photographing skin tones?

For portrait, beauty and fashion photography, CRI 95 should be considered a strong starting point, but the complete spectral behaviour matters much more than chasing a single number.

For skin, pay particular attention to:

• overall CRI
• R9 performance
• TLCI for video applications
• green/magenta deviation
• consistency when dimming
• colour stability across the bi-colour range

A strong red response is particularly important because subtle blood circulation beneath the skin contributes significantly to the colour and dimensionality of a face.

This applies across all complexions. Accurate lighting does not mean forcing skin toward a particular colour. It means providing the camera with enough clean spectral information to reproduce the subject faithfully.

What CRI should you look for in product and commercial photography?

Product photography can be even more demanding than portraiture because the client’s expectation may be literal colour reproduction.

A cosmetic package, fabric sample, painted object or branded product may need to match a physically approved reference very closely.

For this type of work, fixtures approaching CRI 98 or higher, supported by strong TLCI and spectral performance, provide a very useful starting point.

It is also sensible to use a ColorChecker or other known colour reference during the shoot.

As discussed in professional calibration workflows, the chart does not compensate for poor spectral quality. It documents how the camera interpreted known colours under the actual production light.

High-quality illumination and proper colour calibration therefore complement each other.

Does high CRI guarantee perfect colour reproduction?

No.

CRI should be treated as an important indicator rather than a guarantee.

Accurate colour reproduction on set ultimately depends on the entire imaging chain:

• the spectrum of the light
• the colour temperature and white point
• the camera sensor
• the selected white balance
• lens coatings and filters
• exposure
• monitor calibration
• colour-management workflow
• the final display or print medium

A CRI 98 light gives the production an excellent source to begin with, but the rest of the chain still matters.

This is one of the reasons it is better to talk about colour quality rather than CRI alone.

How Maxima approaches colour accuracy

Colour rendering has been one of the fundamental design priorities behind Maxima LED since the beginning.

Across the Maxima professional lighting family, the target is not simply a visually pleasant white source. The fixtures are designed specifically around cameras and demanding photographic applications, with a measured CRI of 98.6 and TLCI of 100.

Different Maxima fixtures then apply that colour philosophy to different production requirements.

Maxima Rapida: high colour accuracy for rugged location work

Maxima Rapida is the rugged bi-colour tool in the Maxima range.

It provides a broad 2,600K to 6,800K adjustable-white range in a compact body weighing approximately 1.8 kg.

More importantly for location work, Rapida carries IP54 protection, making it resistant to dust and splashing water.

This allows a professional crew to combine accurate colour with a fixture designed for environments that may involve beaches, dust, light rain, humidity or unpredictable outdoor conditions.

Direct V-Mount operation also means the fixture can work without a power cable or external ballast, making it particularly attractive for documentary, fashion, wedding, commercial and location filmmaking.

Maxima Spectra: colour accuracy in an ultra-portable package

Maxima Spectra takes a different approach.

It combines the same broad 2,600K to 6,800K adjustable-white philosophy with an extremely compact body of approximately 1.4 kg.

Spectra also introduces a built-in colour touchscreen, providing direct access to CCT and intensity controls on the fixture itself.

For studio photographers, solo cinematographers, small crews and productions that move frequently between locations, this combination of high colour quality, low weight and fast interface control makes Spectra particularly versatile.

Unlike Rapida, Spectra is not designed around the same IP54 weather-protected philosophy, so the choice between the two should depend on the working environment rather than simply on which fixture is newer.

Maxima Furiosa: bi-colour performance for demanding professional sets

Maxima Furiosa brings Maxima’s bi-colour approach into a more powerful professional platform.

Furiosa is designed for productions where high output, professional modifier compatibility and controlled light shaping become central requirements.

Its adjustable-white architecture makes it suitable for cinematographers and photographers who need to move between different lighting environments while retaining the colour fidelity expected from the Maxima system.

The addition of Maxima’s MicroFocus optical technology gives Furiosa another role within the family: not simply producing accurate light, but shaping that light into the harder, more controlled quality often associated with traditional cinematic sources.

Maxima 6: when a dedicated daylight source is the right answer

Maxima 6 demonstrates why bi-colour is not automatically the best architecture for every production.

Maxima 6 is daylight-only.

That may sound less flexible than Rapida, Spectra or Furiosa, and technically it is. But when a photographer or cinematographer already knows that the production will be standardised around daylight, there is no inherent need to introduce adjustable colour temperature.

A dedicated daylight fixture can instead concentrate its design around one highly controlled spectral target.

For colour-critical studio work where daylight is the reference, this specialised approach can be extremely attractive.

The choice therefore becomes one of workflow:

Maxima 6 for highly focused daylight work. Rapida, Spectra or Furiosa when the lighting environment requires adjustable white.

Maxima 3: compact daylight accuracy

Maxima 3 applies the fixed-daylight philosophy to a smaller professional fixture.

It can be particularly useful as part of a compact studio system or as an additional daylight-balanced source where colour consistency matters more than adjustable CCT.

Combined with the bi-colour models, this gives photographers and cinematographers the option to choose the architecture that best matches the job rather than assuming that every production needs the same type of light.

Should you buy the light with the highest CRI number?

Not automatically.

If two fixtures both offer excellent colour quality, practical production characteristics may matter more than a fractional difference in CRI.

A location cinematographer may benefit more from IP54 protection and battery operation than from chasing another decimal point in a laboratory measurement.

A studio photographer may prefer a highly specialised daylight fixture.

A small commercial crew may prioritise the exceptionally low weight and built-in interface of Spectra.

A larger cinema production may need Furiosa’s output and optical control.

The best fixture is therefore the one that combines sufficient colour quality with the right physical and optical characteristics for the job.

The takeaway: CRI is the beginning of the conversation, not the end

Professional bi-colour fixtures commonly achieve CRI 95 and above, while exceptional systems can reach approximately 98 to 99.

But once you are choosing equipment for serious camera work, CRI should be treated as one part of a larger colour-quality picture.

Look at TLCI. Look at R9. Look at spectral data when it is available. Test the light with the camera you actually use. Check colour at intermediate CCT settings and at different dimming levels.

Most importantly, choose the lighting architecture that suits the production.

Maxima’s approach reflects that distinction: Rapida, Spectra and Furiosa provide professional bi-colour flexibility, while Maxima 6 and Maxima 3 offer the focused character of dedicated daylight sources.

All of them start from the same principle: the purpose of a professional light is not simply to illuminate a scene. It is to give the camera the colour information needed to reproduce that scene faithfully.
