Bicolour LED lights are designed to control colour temperature across the visible spectrum, typically from warm tungsten tones to cool daylight. They are not built to emit infrared or ultraviolet light, which operate outside the visible range and require specialist light sources. So while professional bicolour lighting is an excellent tool for standard photo and video work, it cannot replace dedicated IR or UV sources for specialty photography techniques.

Using the wrong light source is ruining your specialty shots before you press the shutter

Infrared and UV photography depend on light energy that sits outside what the human eye—and most standard lights—actually produce in useful quantities. When photographers reach for a bicolour LED panel expecting it to double as an IR or UV source, the results are flat, lifeless images with none of the ethereal or high-contrast qualities these techniques are known for. The fix is straightforward: understand what your light source actually emits, match it to your technique, and treat bicolour lighting and specialty sources as separate tools for separate jobs. If you are unsure which fixture suits your production needs, you can always talk with a specialist to get the right guidance before committing to a kit.

Mismatched expectations on set are slowing down your production workflow

On a working set, time spent troubleshooting why a light is not producing the expected effect is time lost. When crew members assume a bicolour fixture can handle infrared or UV setups without verification, it creates delays, confusion, and reshoots. The practical solution is to plan your lighting kit before the shoot: identify which shots require specialty light sources and which require high-quality, colour-accurate visible-spectrum lights, then bring the right tools for each. Knowing your equipment thoroughly is what keeps production moving.

What is bicolour lighting, and how does it work?

Bicolour lighting is a type of LED fixture that contains two sets of LEDs—one tuned to a warm colour temperature (typically around 2700K to 3200K) and one tuned to a cooler daylight temperature (around 5600K to 6500K). By blending the output of these two LED types, the fixture produces a continuous range of colour temperatures across the visible spectrum.

The key advantage of bicolour LEDs is flexibility. A single fixture can match the warm glow of tungsten practicals or the neutral tone of daylight without swapping gels or changing fixtures. This makes professional bicolour lighting particularly valuable on mixed-light sets where colour consistency matters. The light produced is entirely within the visible spectrum, which is an important distinction when considering specialty photographic techniques.

What is infrared photography, and what light sources does it need?

Infrared photography captures light in the infrared spectrum, which sits just beyond the red end of visible light at wavelengths above approximately 700 nanometres. Standard cameras have an IR-cut filter over the sensor to block this light. IR photography typically requires either a converted camera or a strong IR filter placed over the lens.

As for the light source, infrared photography needs sources that emit meaningful amounts of IR radiation. Traditional incandescent and halogen lights produce significant infrared output as a byproduct of how they generate light. The sun is also a strong IR emitter. Dedicated IR LED arrays exist for controlled studio work. The critical point is that the light source must actually emit energy in the infrared wavelength range—visible-spectrum LEDs, including bicolour fixtures, produce very little usable IR output by design.

Do bicolour LED lights emit infrared or UV light?

Modern bicolour LED lights emit very little infrared or ultraviolet radiation. This is intentional. LED technology is engineered to convert electrical energy into visible light as efficiently as possible, with minimal energy lost as heat or non-visible radiation. The small amount of IR or UV that LEDs do emit is generally not sufficient for IR or UV photography techniques.

This is one of the reasons LEDs have become the preferred choice for most professional photo and video work. Less IR output means less heat directed at subjects, which is more comfortable for talent and safer for heat-sensitive materials. Less UV output reduces the risk of colour shifts in certain materials under studio lighting. For standard, colour-accurate work, this is a clear benefit. For IR or UV specialty work, it means you need a different tool entirely.

Some older or cheaper LED panels do leak a small amount of near-infrared light, but this is inconsistent and unreliable—not a practical basis for intentional IR photography. High-quality professional bicolour lighting fixtures are engineered to keep their output clean and within the visible spectrum.

Can bicolour lighting be used alongside IR or UV sources on set?

Yes, bicolour LED lights can be used on the same set as IR or UV sources, but they serve different purposes and must be managed carefully. Bicolour fixtures handle visible-spectrum fill, key, or background lighting, while dedicated IR or UV sources handle the specialty effect. The two can coexist as long as you understand how each affects your camera sensor and exposure settings.

One consideration when mixing light sources on set is filtration. If you are shooting IR photography with a lens-mounted IR-pass filter, the visible light from your bicolour LEDs will be blocked by that filter. This means your bicolour fixtures effectively become invisible to the camera during IR capture, so they are not interfering with the shot, but they are also not contributing to it. Some shooters use bicolour LEDs for visible-light reference frames and switch to IR sources for the specialty captures.

For UV photography, the situation is similar. UV-reactive subjects glow under UV black lights, and standard visible-spectrum LEDs do not trigger that fluorescence. Bicolour lights can illuminate the surrounding environment or provide a base exposure, but the UV source does the specialty work. Coordination between the gaffer and the director of photography is essential to manage both types of light intentionally.

What are the best lighting options for infrared and UV photography?

For infrared photography, the best options are converted cameras paired with IR-pass filters under strong natural light, or dedicated near-infrared LED arrays for controlled studio environments. For UV photography, UV black lights (fluorescent or LED-based UV sources) in the 365-nanometre range produce the strongest fluorescence effects on UV-reactive subjects.

  • Infrared outdoors: Natural sunlight is the most powerful and accessible IR source. A camera converted to full-spectrum capture with an IR-pass filter provides the most control.
  • Infrared in the studio: Dedicated IR LED panels or incandescent/halogen sources provide continuous IR output. Halogen work lights are a low-cost option with strong IR emission.
  • UV photography: LED UV sources at 365 nm produce cleaner results than cheaper 395 nm options, which can leak visible violet light and reduce contrast in fluorescence shots.
  • Mixed visible and UV setups: High-quality bicolour LEDs work well as fill or ambient light when shooting UV-reactive subjects, as long as the visible light is managed to avoid washing out the fluorescence effect.

The choice of light source always comes back to understanding what wavelengths your technique actually requires and selecting equipment that delivers them reliably.

Frequently Asked Questions

Can I convert my bicolour LED panel to emit infrared light with a filter or modifier?

No, adding a filter or modifier to a bicolour LED panel will not make it a functional IR source. Filters can block unwanted wavelengths, but they cannot create wavelengths that the light source does not already emit. Since bicolour LEDs are engineered to produce visible-spectrum light with minimal IR output, there is simply no meaningful IR energy to pass through an IR-transmitting filter. For genuine infrared photography, you need a source that inherently produces IR radiation, such as halogen lights, sunlight, or dedicated IR LED arrays.

How do I know if my camera is capable of infrared or UV photography without sending it for conversion?

A quick at-home test for IR sensitivity is to point a TV remote control at your camera lens and press any button while live-viewing the scene. If your camera sensor picks up the remote's IR LED as a visible purple or white flash on screen, it has some IR sensitivity that may be workable with a strong IR-pass filter. For UV photography, sensitivity testing is more complex and generally requires specialist equipment, so consulting your camera manufacturer's specifications or a conversion service is the most reliable approach. Keep in mind that even cameras with some native IR sensitivity will benefit greatly from full-spectrum conversion for serious IR work.

What common mistakes should I avoid when setting up a UV photography shoot?

The most common mistake is using cheap 395 nm UV sources instead of true 365 nm lights, which causes visible violet light to bleed into the frame and significantly reduces the contrast and vibrancy of fluorescence effects. Another frequent error is not controlling ambient visible light tightly enough — even a small amount of spill from standard room lighting or your bicolour LEDs can wash out the fluorescence on your subject. Always shoot UV setups in a darkened environment and use a UV-pass filter on your lens if you want to isolate the fluorescent effect cleanly.

Is there a risk that bicolour LED lights will interfere with or contaminate an IR photography setup?

In most practical scenarios, bicolour LED lights pose very little risk of contaminating an IR capture. Because high-quality bicolour LEDs emit negligible IR radiation, and because IR photography is typically shot through an IR-pass filter that blocks visible light, the two systems are largely isolated from each other. The main concern is not IR contamination from the LEDs, but rather ensuring your visible-light bicolour fixtures are not causing unwanted reflections or lens flare that could degrade image quality. Flagging and controlling spill from all light sources remains good practice regardless of the technique.

How should I brief my crew or rental house when putting together a kit that includes both bicolour and specialty light sources?

Be explicit in your kit list about which sources are for visible-spectrum work and which are for specialty capture — do not assume rental house staff or crew members will infer the distinction. Specify the exact wavelength range you need for any IR or UV sources (for example, '365 nm UV LED' rather than just 'UV light') to avoid receiving the wrong equipment. It is also worth briefing your gaffer and camera operator together so that exposure settings, filtration, and light placement decisions are made with a shared understanding of how each source behaves on set.

Can the Maxima Rapida or similar high-quality bicolour fixtures handle colour-critical work like skin tone matching or product photography without additional colour correction in post?

Yes, professional bicolour fixtures like the Maxima Rapida are designed to deliver accurate, consistent colour rendering across their full colour temperature range, which is exactly what colour-critical work demands. A wide colour temperature range (such as 2600K to 6800K) combined with high CRI and accurate white point tracking means that skin tones and product colours render faithfully straight out of camera, minimising the need for heavy correction in post. That said, it is always good practice to set a custom white balance in-camera and verify colour accuracy with a colour checker chart at the start of any critical shoot.

What is the best way to get started with specialty photography techniques like IR or UV if I currently only own bicolour LED lights?

The most accessible entry point for infrared photography is to start outdoors in bright sunlight, which is a strong natural IR emitter, and add a quality IR-pass filter (such as a 720 nm filter) to your existing camera lens. This lets you test the technique and understand the look before investing in a camera conversion or dedicated IR studio lights. For UV photography, a single 365 nm UV LED torch or panel is an affordable first purchase that lets you experiment with fluorescence effects on a small scale. In both cases, your existing bicolour LED kit remains useful for setup lighting, reference frames, and any visible-spectrum elements of the shot.
