The MediaLight Pro 6500K CRI 99 Ra Bias Lighting System



The MediaLight Pro:
Our D65 CRI 99 bias light for unparalleled accuracy and consistency

Our standard MediaLight units are 95 Ra. A CRI of 95 is also suitable for professional use. 

Why did you make CRI 99 bias lights just to illuminate a spectrally flat gray backdrop? 

1) Because we could.  
2) Because we believe it is where consumer LED technology will be in a few years. 
3) Because if somebody was going to do it first, we figured it might as well be us. ¯\_(ツ)_/¯ 

The 20-inch MediaLight Pro does not include a remote (the dimmer is on the cable).  It is not suitable for wall mounted displays.  Instead, use the MediaLight Verso Pro. It still runs off of 5v 1a, USB 3.0.  It includes a dimmer and remote control. 

Technology marches on, and we're sure that within the next 18 months, all of our standard products will have a CRI of 99 Ra. Our first MediaLight was a breakthrough and it was only 90 Ra, and this was only 2 years ago. 

The MediaLight Pro was created for colourists who need the highest CRI and the most uniform spectral power distribution in a bias light for their professional displays. The Pro uses an entirely new class of ColorGrade™ SMD (LED) chips, powered by near-violet photon engines, and with an incredible colour rendering index (CRI) of 99 Ra (TLCI 99.3 Qa). The MediaLight Pro is indistinguishable from daylight to the human eye.

It's an entirely new kind of bias light, powered by an entirely new class of SMD (LED) lighting. 

The human eye primarily sees wavelengths between 400-700 nanometers. The spectral power distribution curve (SPD) for the MediaLight Pro reveals that instead of the telltale harsh blue spike found in traditional white LED systems, the near-violet photon engine's energy falls largely in the subperceptual range.

Most commodity LED lighting systems fall apart in the R9 and R12 values, which are not included in CRI calculations, but are necessary for the faithful reproduction of skin tones and deep reds. They are often replaced with much more energy-efficient, and cheaper green phosphors, which can result in a greenish colour cast, even when used to illuminate a grey surface, such as is the case with bias lighting. Beyond the violet photon engine, which eliminates "blue spike," The MediaLight Pro uses a special blend of phosphors that include these vital reds, resulting in a much smoother SPD and more natural light.

With a colour rendering index (CRI) of 99 Ra (TLCI 99.3 Qa) and CCT of 6500K, the MediaLight Pro is the most advanced D65 compliant bias lighting system available today.

It is compact. It can be powered by the USB 2.0 or USB 3.0 ports on your professional monitor, and it costs 1/3 the price of high-CRI, blue emitter-based professional bias lights that are less accurate.

MediaLight Pro features:

  • 6500K CCT (Correlated Colour Temperature)
  • CRI 99 Ra (TLCI 99.3 Qa) ColorGrade™ SMD (LED) chips
  • 50 cm flexible light strip or rigid aluminum channel versions -- a perfect fit for your 24" professional monitor
    • The 4m Verso Pro will go entirely around four sides of a 60" display , or cover 3 sides (left, top and right) of a display up to 85"
  • 4ft USB extension cord - can be powered from USB 2.0 or USB 3.0 ports on your display or computer
  • Included PWM dimmer
  • 5v USB Power
  • Included wire routing clips 
  • Peel and stick 3M VHB mounting adhesive
  • 5 Year Limited Warranty

Generally speaking, you should not mix and match standard 95 Ra MediaLights and 99 Ra MediaLight Pros in the same installation. While the chromaticity coordinates are virtually identical, the spectral power distribution and color rendering index is different, and this can result in a perceptual difference, which varies by the individual.

This also happens with professional displays that use different technologies (OLED, Quantum Dot, LED).  While perceptual matching can be performed on a display by the end user (i.e. Judd Vos correction), this matching is only correct for the individual. This is why an OLED display might look greener than an LED display even when both are calibrated the same way.
