The MediaLight Pro 6500K CRI 99 Ra Bias Lighting System
QUESTIONS & ANSWERSAsk a Question
What is the lumen output for the MediaLight Pro 20" (either strip or fixture version)?
Maximum output is about 350 lm. Output is limited by being powered by 5v USB power. Hooking to a more powerful connection is not an option. For brighter output (800 lm per meter) the 5m Pro 12v would work.
However, that's far too bright to use as bias lighting in the vast majority of situations. If you are using them for a different application, we recommend our Mk2 bulbs instead. 800 lm and TLCI 99.
Hello, i would like to know if there will be 99Ra MediaLight Pro for television (upto 85" and/or quad) with remote controlled dimmer and rigid fixture? (I worry about permanently sticking stuff on my tv). Thanks!
We are currently building larger versions of our MediaLight Pro line. Due to extensive testing, we expect that they will be ready in late January. The pricing for the Pro version of a single strip or Quad is estimated to be about 2.5 time the price of the standard 95 Ra version.
You may want to use the included wire clips to attach your strips. Once the strips are adhered to the TV they are virtually impossible to remove intact.
Does this have multiple color options that you can change? or will it only show white?
Nothing for sale on our site changes colors. Everything on our site is “video white” D65/6500K professional reference-quality bias lighting. Instead of making your wall change colors, this kind of light will make the colors on your TV look better.
What's the difference between the rigid version and the strip version?
The strips have identical output and length, it's just that the rigid version comes pre-installed in a custom, all-black, aluminum channel, making it more like a fixture (albeit a very slim one) for people used to using systems like fluorescent tubes. This allows for easier mounting and removal in some settings, as the VHB adhesive on the strip version can make future removal a challenge. The rigid versions includes VHB tabs so that you can still stick it to the back of your monitor.
The MediaLight Pro:
Our D65 CRI 99 bias light for unparalleled accuracy and consistency
If you are a professional colourist, can can also go here to purchase the MediaLight Pro.
Ou MediaLight Mk2 series has CRI of ≥98 Ra. Performance is very similar between the Pro and Mk2, although the MediaLight Pro uses a near-violet emitter. This moves the photon-emitter spike below what the human eye can see (most of us, anyway). The remaining SPD bears striking similarities to D65 sunlight, excluding infrared light, of course. However, as with all of our products, we never claim that our products are D65. We use the term "simulated D65" due to the obvious differences between sunlight and LED light.
Here in 2020, it would be inaccurate to call manmade light indistinguishable from sunlight. We can determine the chemical composition of distant stars with spectrophotometers and we can certainly tell sunlight from LED sources.
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, however, and we're sure that within the next 18 months, all of our standard products will have a CRI of at least 98 Ra and TLCI of 99. (Note from 2020: this has already happened with our Mk2 line and it took 20 months).
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.
