MediaLight 6500K Single 140 cm Strip
QUESTIONS & ANSWERSAsk a Question
I just got a Sony A8G OLED TV (65 inch) and was wondering how to identify the appropriate light level for the bias light. I know for SDR we use a 10% pattern to compare once the brightness of the tv is set to a comfortable level but with HDR I imagine the range of the brightest white increases and thus the 10% pattern for SDR would not equal 10% of the HDR mode's brightest white. Plus the brightness of the screen in that mode is not really user adjustable without negatively impacting the HDR effect. Would the bias light need to be brighter when viewing HDR content?
I still recommend using this brightness reference pattern and its target of 10%
Why? The jury is still out on the ideal brightness levels for HDR. For example, SMPTE ST 2080-3:2017 recommends 5 nits (technically 4.5 nits -- both of which are VERY dim) for HDR content. Many feel that this is much too low. I happen to think its ok for OLED, though, where people get squeamish about not having their entire room go dark at the end of the scene.
Some people get really caught up in that and want the satisfaction of complete darkness -- until they go crazy when they see banding in the shadows. Then they buy a bias light. :)
On the other hand, ISF still recommends a brightness of 10%-15% for HDR. In other words, the HDR recommendation from ISF is still very similar to the brightness level for SDR -- maybe a touch brighter. (I can find documentation, but during ISF certification, I was told this by Joel Silver directly). If you are not caught up in the fade-to-black hoopla, 10% still seems to be the best choice for all-around viewing.
Will the USB power work if it's a 2.0 USB port?
Yes, for this model and the eclipse. Larger units require USB 3.0
Will this work on a 85” stand mounted Sony 900F?
Yes, a single horizontal strip is all that is required for a TV sat on a stand.
You could also use our Flex, Quad or Quad XL, depending on your preferences. The single strip tends to have a broader halo and the other units can have a smaller halo if that's desired since the other versions would be closer the the edges and could be set to a lower dimming level - rather than a brigher strip projecting from the center of the back of the display.
How wide is the strip?
Can Alexa control the single 6500K
Every MediaLight Bias Lighting System for TV (this excludes the Eclipse and Pro, for computer monitors) includes an IR remote and dimmer, which is interoperable with any smart hub equipped with an IR bridge. Compatible hubs include Logitech Harmony and Broadlink Mini 3, but any hub with a learning mode can learn the IR commands (we've uploaded the codes to Broadlink, but learning mode is needed for Harmony at this time).
Will it work with 82" TV (around 72.5 inch in length)? Thank you
Yes, however, only if the TV is on a stand. If the TV is on a wall mount, you should go with one of the sizes of the Quad.
Will the 140cm work on a 60" tv
For virtually all TVs on a stand up to 75", the single strip is bright enough and casts a large enough halo. It will need to be dimmed for reference levels. The dimmer is in the box. For wall mounts, you want the Quad.
How does this light change colors. I stuck it on my TV but I only see white.
Please see the answer to this question below. 🤪
How does the IR remote work? Won’t the tv block the line of sight to its sensor?
The IR receiver is placed close to the edge of the TV and can be reached by either direct IR light or reflected (off the wall) IR light. If placed away from the edge, the TV can block the infrared light.
Does this product change colors? Are you able to set the lights to color change at slow/fast speeds? Or are the lights just one color?
No. 😊 D65 white only.
Does this change colors?
No, there is a difference between full-spectrum D65 white light and colour-changing. Our lights don't change colours and are remarkably stable.
Our bias lights emit a very particular wavelength of light. They are based on the CIE (Commission internationale de l'éclairage) D65 standard illuminant, which means that they are designed to closely mimick the sun, which is the basis of "video white" or the colour of light that all TVs are based upon. The purpose of this is to make the content on your TV look as the director intended. In fact, there's a very good chance that the director and team used the MediaLight to edit and colour grade the film.
When you use a bias light, it should be the only light on in the room during viewing, so it's also acting as a high quality, high-CRI light source in your room. Placement behind the TV ensures that there is no glare and really makes the colours and contrast pop. It improves the picture on your TV in ways that few other tweaks can.
If your TV is on a stand, this is the MediaLight model for you. If you are using a wall mount or articulating arm mount, we recommend the MediaLight Quad.
