What you are really asking is: “Does the USB port on my TV turn off when the TV us turned off?
The answer is, “It depends.”
Bias lights plugged into a TV will turn on and off with the TV only on models that cut off power to the USB port when the TV is turned off.
Don't all TVs do this?
Unfortunately, they don’t.
Some TVs leave the USB port on when the TV is off. Other TVs turn the USB port on and off every 10 seconds when the TV is turned off (Sony Bravia, for example).
Note: We've posted a partial fix for the Bravia Bug. It only stops the flashing and keeps the USB port on constantly. This, however is enough to run power from the TV while using the MediaLight remote or a smart hub to turn the lights on and off.
Some generic LED manufacturers claim that their lights, which often lack remote controls or even an on/off switch, turn off automatically with the TV. At best, this is misleading, and at worst, it’s false advertising.
This is why we include an AC adapter and a remote control with our MediaLights for TV.
You can teach the remote control commands to your universal remote or smart hub with IR blaster.
However, if your TV does turn off the power to your USB when the TV is turned off, your MediaLight will lose power and I guess that you could call this "turning off."
Frequently Asked Questions
What you are really asking is: “Does the USB port on my TV turn off when the TV us turned off?
Yes, they do.
No. Our sole focus is manufacturing accurate, reference-quality video white bias lighting, desk lamps, fixtures and bulbs.
We don't make any color-changing products. None!
Not only that. We take great care in ensuring that you can dim your MediaLight from 100% all the way down to 2% without impacting the color temperature.
If you spent time and money calibrating your display, you are aware that bias lights that change colors or using the wrong white point will "uncalibrate" your display from the observer's perspective.
Our lights won't make your wall change colors, but they also won't adversely impact the colors on the screen like color-changing lights do.
If you want to enhance your display with bias lights that improve the perceived quality of the colors and contrast on your screen, while reducing eye fatigue and preventing image retention, you've come to the right place. MediaLight is recognized for accuracy, reliability and fair pricing by post-production professionals and consumers alike.
The good news is that our higher build quality results in longer lifespan. Where commodity LEDs have a life expectancy of about 1 year, every MediaLight strip is warrantied for 5 years, illustrating the old cliché, "buy one, cry once."
We are based in New Jersey and ship our orders from New Jersey. Orders placed before 3pm are shipped the same day.
Ordinarily, delivery would take 1-5 days for delivery most of the USA, depending on the shipping method selected. However, this is currently not guaranteed due to various reasons (pandemic, weather, and service cuts to name a few).
If you are having a TV installed on Thursday and you need your lights delivered by Thursday morning, only UPS offers a guaranteed delivery window at this time. However, please note that we will only refund UPS shipping if delivery is not attempted and if service level guarantees are not suspended. In other words, if we do not qualify for a refund for shipping from UPS, we will not issue a refund for shipping for late deliveries.
Place a MediaLight next to a low quality LED strip. That difference that you see is how wrong the other light is compared to an accurate light simulated D65 light source.
Look at skin tones under a low quality light and then again under a CRI 98 MediaLight bias light or bulb. Light sources that lack vital red spectrum don't look right when reflected off of skin tones. One very important part of display calibration is ensuring that skin tones look natural.
With a transmissive display (i.e. a TV), the light isn't reflected off of the display, but the properties of the ambient light in the viewing environment still have a inverse effect on what we see on the display.
It's similar to why warm lighting makes the TV look too blue, or lights with too much magenta make the image look green. But rather than being a function of the chromaticity coordinates, spectral adaptation is caused by the spectral power distribution of the light source.
When we adapt to lights with inaccuracies, the display also looks inaccurate, but in the opposite direction.
Confusing? Think of how iPhones and Android phones now have settings adapt to the white point in the room. If you turn TrueTone or "adaptive display" on or off, the white point of the display changes dramatically, showing you how much the ambient light has shifted your perception of the screen. If you don't use those settings, the display can look too warm or cool, depending on the lighting.
Because there are missing colors in poor color rendering lights (generalized as low CRI), the spectral deficiencies can impact how we perceive those same colors on the display. More of the color-sensing cones in our retinas are dedicated to seeing red than the other primaries, and displays comprise red, green and blue subpixels.
Additionally, light sources that lack red make up for it by using yellow light to achieve their target white point (yellow + blue = low CRI white). We are most sensitive to yellow/greenish light, which partly explains why those lights with poor color rendering often look yellow and green rather than looking like sunlight.
Everything is covered.
"The dog chewed my remote control"
"I accidentally cut the power end of the light strip."
"The basement flooded and took my home theater with it."
Our customers will back us on this; we've never denied a warranty claim. We use quality components and our bias lights are built to last.
However, if something does go wrong, we view it as a chance to remind you of why you picked us. If we had to compete on price, using the high quality, ISF-certified components that we use, we'd be dead. However, we realised that there was a hole in the market when it came to accuracy, quality and service.
We'd rather focus on making great lights than try to figure out whether a claim is covered. (This doesn't mean that we won't ask to prove that you own the lights before sending replacement parts).
The only caveat is that if you ordered from outside of the USA, in a region where we have a local distributor, you might be asked to pay for anything faster than standard USPS first class international package mail for replacement parts.
(MediaLight desk lamps and light bulbs have a 3 year/30,000 hour warranty).
The customer pays return shipping and, yes, there are restocking fees if a MediaLight is not returned in the same condition in which it was sent to you. Those are outlined on our Returns & Exchanges page.
If you change your mind, just send your MediaLight back within 45 days. You are responsible for all round-trip shipping costs. We don't refund any shipping charges associated your order and you must provide the return postage.
MediaLight units that are not returned in "good as new condition" are also subject to restocking fees of up to 25% (more if items are missing).
No returns are permitted after 45 days.
If you would like to test the MediaLight with your setup, you can do so with temporary adhesives like masking tape. If the included adhesive is used, the 25% maximum restocking fee applies. Restocking fees are in addition to shipping costs, which are deducted from refunds.
There is never charge for domestic exchanges or warranty claims during the 5 year warranty period, however you must pay international shipping.
People ask this question from time to time. We don't charge extra for the warranty. We provide a 5 year warranty because our products are engineered to last for at least 5 years. If we didn't include the warranty, we'd still charge the same amount for the product. It is expected to last much longer because of how it is designed, so we warrant that you will not need to pay another cent for five years.
No, you can't see the infrared LED on the remote control because it is infrared. The remote control does not light up visibly. The MediaLight does not use a radio frequency remote. It does not visibly light up when you press a button.
Part of the confusion is due to the fact that our original remotes were RF and did light visibly. The last RF remotes were shipped over 3 year ago.
If your remote control isn't working as expected, we're 99% certain that one of these fixes will solve your problem.
Manufacturing costs. Our manufacturing costs exceed their retail prices. We aren't interested in doing it cheap. We're only interested in doing it right.
If you don't care about accuracy and don't know why display calibration is important, you can literally buy anything else and it won't matter. If you care about accuracy, we eliminate the guess work and provide a solution that is guaranteed to not need replacement for 5 years.
We use custom ColorGrade SMD chips for accuracy in chromaticity and color rendering. Those other lights don't. That doesn't mean that they are bad lights for camping or lighting your basement staircase, it just means that they are not suitable for bias lighting behind your calibrated display.
The minimum color rendering index (CRI) for a MediaLight in 2020 is ≥ 98 Ra and the TLCI is 99. In our first year (2015), our lights were just over 91 Ra. Our MediaLight Pro has an extremely solid CRI of 99 Ra and TLCI of 100.
How accurate is that? Some would say that makes them indistinguishable from the sun. We don't say that, however, because with a spectrophotometer, we can distinguish any man-made light source from the sun. It is, however, very, very good. Exceptional.
Aside from the quality of our chips, we include everything that you could need for the ideal bias lighting setup. We include a dimmer, a remote control (on TV models) as well as wire management clips and velcro straps to tidy up your installation.
We won't often be the cheapest option, but our markups are more modest than those selling systems made with inferior chips, cheap PCB and without absolutely-required features like dimmers. You'll be using your MediaLight well into the future, long after low quality lights are in landfill. Ask around. You'll see. We cover everything under our warranty because MediaLight is built like a tank.
Do you prefer to view a calibrated display? If so, you will absolutely see the difference when you accurate MediaLight bias lights. As improbable as it may seem, placing inaccurate lights behind a calibrated display essentially "uncalibrates" the display because it has a subtractive effect on what we see. If you place harsh blue, low CRI lights behind a TV, your image will look warmer to your eyes.
Do you want to make the wall look colorful, or are you trying to enhance the picture? Our customers don't stare at walls. They'd much rather watch the content on the screen.
But we're not here to argue. Buy what you want to buy. Light bleed is something that most people try to eliminate, not add. In the worst cases, it makes the picture look desaturated and the colors seldom match the TV. Worse still, it's often laggy. If you are an OCD type like us (our #1 type of customer, by the way), it might drive you bananas. There's plenty to find wrong. It's distracting.
However, if you are going to spend that kind of money on colored lights, we'd argue that you'd get more bang for the buck and cover a similar amount of wall space by purchasing a larger display. With a 65"-90" display, the picture is very immersive. When Philips launched Ambilight in 2004, TVs were maxing out at around 40"-50". There was still some bare wall -- not that was an excuse, but colored lights look silly on an 85" TV unless you have 14 foot ceilings.
No. Everyone has opinions about what looks best. We have science and standards. Our lights are certified by the Imaging Science Foundation. Every MediaLight. From the $32.95 Mk2 Eclipse to our most expensive units is ISF certified.
If you look on the message forums, you can read about cool white, warm white and rainbow colored bias lights until your eyes glaze over. If any of them did what they were supposed to do, we wouldn't have been able to carve out a niche charging considerably more for our lights (fact: our manufacturing costs are higher than their retail prices and our profit margins are much lower).
If you are a professional colorist, we made The MediaLight for you. If you care about home theater and know the value of a calibrated display, we made The MediaLight for you.
We manufacture the very best high CRI (98-99 Ra) CIE Standard Illuminant D65 (6500K; x=0.3127, y=0.329) compliant ("reference standard" video white) bias lights for the professional and consumer market and sell them at a very reasonable price and with a 5 year warranty.
Reference bias lighting is all about making the picture look as the director intended. We are perhaps less dogmatic than some -- if you like colored lights flashing on your walls, we're not going to try to talk you out of them. After all, there is no accounting for taste.
However, placing color behind the display alters our perception of what is on the display. This is just how our eyes and brains work. A warmer color like orange or red behind the display will make everything on the screen look bluer. A cooler color temperature like blue, will make everything look more red. This might not be disastrous when watching The Bachelorette, but you wouldn't want to do it in your coloring suite or while watching Breaking Bad.
The MediaLight Bias Lighting system offers an extremely accurate D65 simulation. When you do read marketing language that promises "perfect" or "absolute" D65, be skeptical.
There are no actual D65 light sources aside from sunlight under very specific conditions (reconstituted through the Earth's atmosphere, in late afternoon and in Northern Europe), only simulators. The quality of a simulator can be assessed with the CIE Metamerism Index. The full spectrum, ultra-high CRI ColorGrade™ LEDs in our MediaLight Bias Lights represent the best of what is currently available.
We're a bit wary of companies who call their products "perfect" or "exact D65" to charge more and prefer to not to engage in this practice. Our products are compliant with industry standards. We're pleased about how well we stack up and the Imaging Science Foundation agrees. We're ISF-certified and our lights are tested for color accuracy and consistency. We prefer to underpromise and overdeliver.
According the LUMU manufacturer support pages, lower CCT measurements on the Lumu device can be off by as much as 300K and higher CCT measurements can be off by up to 3000K. Our lights are in the middle of those two extremes at 6500K and our binning specifications are much tighter than the tolerances of the Lumu device.
Simply put, we are sorry if you are receiving inaccurate results on your Lumu. Our lights are reviewed throughout the production process, and independently verified in the lab of the Imaging Science Foundation. We don't modify our lights so that they measure differently on a particular model of meter and there are factors that can impact the measurements taken outside of a lab environment.
Some have asked, "Why do they make a meter that is incapable of precise measurements?" Our answer is that precision, in some fields, is relative and the wavelengths being measured also fall into different ranges of color temperature and spectral power distribution, which may be measured more accurately by certain devices.
In photography, the difference between 2300K and 2400K is much more noticeable to the human eye than the difference between 6500K and 7000K and the use of tungsten-based or equivalent lighting in film is usually in the 3200-5000K range. This is, per the Lumu website, where the results on devices like Lumu are most accurate.
The meters used in our production and testing processes, however, are capable of more-precise measurements in the higher CCT range than a $200 iPhone dongle. While one light might give you a result that is closer to 6500K on one of these devices, the device is relying on assumptions about the spectral power distribution of the lights that are beyond its measurement resolution and capabilities.
5v 1a lighting can’t exceed a theoretical maximum brightness of about 400 lumens. This is far brighter than in should be, and you will still need to dim your lights significantly to achieve reference levels. Larger 5v strips simply spread the light over a larger area — they are not brighter, with a few exceptions. For example, a 6 inch strip will be brighter than a 4 inch strip.
If you need brighter lights, our 800 lumen MediaLight bulb or our 12v and 24v light strips offer far more brightness. However, our 12v strips don’t sell nearly as well as the USB-powered lights because the extra brightness is not needed, and most people prefer to power from the TV.
Our MediaLight single strip outputs a theoretical maximum of approximately 400 lumens (42 LED's at roughly 20lm each). This is on par with what a popular fluorescent bias light would output. We use only 5050 (5x5mm) LED's, not the smaller and weaker 3528 (3.5x28mm) variety. These are not commodity LED strips. They are built with LED's that we source. There are, however brightness limitations when running off of USB power. However, because most bias lighting is run with a dimmer, you will not likely encounter these limitations in normal use.
Our MediaLight Quad outputs approximately 400 lumens at maximum brightness. There are, however, brightness limitations when running off of USB power. However, because most bias lighting is run with a dimmer, you will not likely encounter these limitations in normal use.
Regarding HDR, yes they are bright enough. HDR video uses brightness regions to help make video look more like reality. The MediaLight exceeds the output requirements for an HDR display bias light.
Yes. It sure is. You will probably need to dim it with the included remote dimmer. If your TV is on a wall mount, you probably want the 5m or 6m Mk2 Flex.
This works pretty well. :)
In all seriousness, there are other solutions, such as placing a neutral backdrop (wall cling or fabric) behind the TV.
Yes, you can cut between the copper contacts anywhere on the MediaLight strip.
No. Our bias lights are truly 6500K and ≥ 98 CRI for our standard MediaLight models and 99 Ra for our MediaLight Pro line. Sometimes we think that LED bias light manufacturers just guess at 6500K because the measurements during our tests were universally and outstandingly bad. We verify all of our components with state-of-the-art instrumentation and then we ensure that we don't mess them up while assembling the light strips. These are not aquarium light strips repackaged as bias lights.
One reason why we use a black strip instead of a white strip, which would be more efficient, is that white strips can interfere more with the color temperature than black PCB strips, especially as they age. (Look at the white finishes of electronics that sit out for any length of time).
Experts agree that a bias light should be the color of sunlight on a hazy day, or something called the CIE D65 standard illuminant. We used a calibrated Photo Research SpectraScan PR-650 and Sekonic C7000 to measure our component light emitting diodes. Our partners then test them on their PR-670 to verify our findings.
If a better solution existed, we wouldn't have come to market with The MediaLight. Simply put, none of the other LED-based light kits on the market even come close to 6500K, despite what they say on the tin. The Antec light that we tested was over 9500K, which is practically sky blue. Another popular brand was shockingly over 20,000K! Ours are 6500K, and we mean it. Put them side-by-side and see for yourself. Better still, shine them on a neutral grey card and take a measurement with a calibrated probe. You will be pleased.
Our lights are not only accurate enough for home use, they are used by professionals who color grade the videos we enjoy on our home theater systems. In fact, if you are a professional with an account with Flanders Scientific, we highly recommend buying The MediaLight from them.
As of 2020, all of our LED's have a CRI of at least 98 Ra. Our popular MediaLight Pro has a CRI of 99 Ra -- an industry first.
Our bias lights are very accurate - more accurate in fact than fluorescent bias lighting solutions -- with a high CRI and a correlated color temperature of 6500K.
Nevertheless, we don't believe that any of the bias lights on the market, including our own, should be marketed as D65. The CIE D65 standard illuminant is derived from sunlight in a slightly hazy sky. In our view, any artificial bias light is "simulated D65," and has different spectral power distribution than natural sunlight.
So, yes. To the extent that an LED is capable of simulating the CIE D65 standard illuminant, The MediaLight is a very accurate solution. Of course, you will immediately recognise a fluorescent or LED light source under a spectrophotometer. A properly-filtered (removing excess infrared) tungsten halogen bulb would be closer to the spectral power distribution of D65, but the form factor, heat output, energy inefficiency and short lifespan limit the use of tungsten bulbs.
In a word, no, but it's because good bias lighting needs to be adjusted.
The SMPTE Recommended Practice document says the brightness of a bias light as reflected off the surface behind the TV should be less than 10% of the peak white level on the viewing device. Without a dimmer, LED strips are blazingly bright. This can result in crushed blacks, an extreme halo effect and negate some of the benefit of using bias lights in the first place.
Additionally, there are situations where you may have a white wall behind a TV instead of the recommended neutral grey. By adjusting the brightness of the lights you can ensure that they don't exceed the maximum recommended brightness for ambient light.
Other systems, such as fluorescent bias lighting systems are not dimmable, but are used in combination with baffles and/or neutral density filters to achieve the ideal level of illumination.
We used to sell our original MediaLight products on Amazon. That is, we did until the COVID-19 pandemic hit. Then, any order that was not deemed essential was severely delayed. 30-40 day delays were the norm.
Meanwhile, with everyone stuck at home, demand for new TVs and accessories soared, but our Amazon orders were tied up with no end in sight. We realized that we couldn't be beholden to another company anymore. We'd put all of our proverbial eggs into one proverbial basket.
We decided to remove our products from Amazon and sell them directly. With our office closed, we shipped from our garage and arranged for daily contactless pickup by USPS, UPS and DHL.
In the process, we learned that most people weren't discovering our products on Amazon. They were going there because, in many cases, it was more convenient. However, it's not convenient when you don't get the complete information about a product and end up buying the wrong size or shape for your installation. It wasn't convenient for people who had no idea that their 4 year old lights were still covered under a 5 year warranty, or for people who thought that our lights changed colors because they sorted products by price and assumed that our price meant that our products changed color.
When we released the new Mk2 series in July, we decided that we'd offer it only on our site and through our international authorized dealers. It's less stressful and we get to know our customers a lot better. We have so many web chats, phone calls and video calls (we'll look at your setup prior to installation if you need a hand) that teach us more about how customers are using our products. We provide better advice and service too.
MediaLight Bias Lighting is a division of Scenic Labs. Founded in 2009, we are the publishers of the Spears & Munsil Benchmark. Before that, our founders worked in the same industry and video calibration industry for another decade, publishing Digital Video Essentials. So, you could say that we live and breathe home theater reference standards in everything we do. Thanks to our specialty we have access to the domain expertise of some great imaging scientists, as well as some really cool lab tools.
The bias light space has been a pretty sleepy affair over the last few decades. Aside from a few bright spots, such as one of our favourites -- the now-discontinued Ideal Lume (fluorescent) lights, most of the products on the market were either overpriced, cheap garbage, or overpriced garbage. We liked the accuracy of the fluorescent systems but wanted to combine accuracy with the convenience of LED's.
A similarly-priced set of bias lights from Amazon claimed to be 6500K, but the LED's were not accurate at all! They looked green and blue! How do I know that your bias lights are any different?
All white LED's are driven by a an underlying blue diode (Please note, here in 2020, our MediaLight Pro is driven by a near-violet diode with no blue spike). The diode directs photons at a blend of phosphors and those phosphors, in turn, glow white. When the blend of high-quality phosphors is just right, you get the color temperature that you need based on how the human eye sees color.
You can take a closer look at the spectral qualities of light by studying it under a spectroradiometer. A tell-tale sign of white LED lights is the blue spike above (all lights have their own characteristics - tungsten, fluorescent, sunlight, neon, etc). While it looks like this would result in a blueish light, this is actually the spectrograph of one of our extremely accurate LED's. The other colors are present in just the right balance to result in a 6500K color temperature and CRI of ≥ 98 Ra. Of course, the measurements were taken in a controlled laboratory setting and taken off of a neutral grey card as is necessary for an accurate and consistent reading.
