See What the Director Intended ™

The Radiance Pro™ series supports 4k60 inputs, and outputs, including HDCP 2.3, HDR10, and HLG, and is compatible with Dolby® LLDV™ sources. Winner of a Home Cinema Choice™ Best of 2021 award, and a Best Video Product award in Australia in 2021, the Radiance Pro is not standing still. Lumagen is adding to its 22-year legacy of video processor development by continuing to enhance features and algorithms, and adding a single-input, single-output model for those who would like to place the Radiance Pro after the AV switching.

The Radiance Pro series of video processors offers up to ten inputs, four outputs, and a multitude of video processing, setup, and calibration features. Much more than an HDMI switcher, the Radiance Pro has a host of features to improve the image on your screen. It is considered by many experts to be an essential part of any quality home cinema.

Optimizing HDR content has perhaps become the most important video processing feature. The Radiance Pro Dynamic Tone Mapping (DTM) analyzes multiple regions of every frame of content, detects scene changes, and optimizes the image for each frame of content. Jon Thompson, a movie producer who is responsible for post-production image quality at a major studio, recently evaluated the Radiance Pro DTM versus the other options. He said that “the other DTM options are not even in the same league as the Radiance Pro.”

Scaling quality again comes to the forefront with the 4k projectors and televisions. It should be intuitively obvious that home cinema scaling must be evaluated at viewing distance using actual moving image video content. The Tektronix PQA600C quantitative image analysis program is used by major studios and broadcast networks and includes 30 years of development by perception physicists. It includes viewing distance in its evaluation of scaling. The Radiance Pro has the industry’s best motion picture scaling and scores more than 20% higher than the competition using the Tektronix analysis software. Lumagen’s scaling provides the best quality scaling for 1080, 720, and SD, sources for 4k projectors and TVs. Scaling is also essential for aspect-ratio control, especially when using an anamorphic lens. In addition, the Radiance Pro has an edge-sharpening feature that helps restore detail lost during compression of the digital content.

Minimizing signal jitter is an extremely important criteria for HDMI. The Radiance Pro 5XXX series HDMI output clock jitter has been measured at about 10 pS. This is an ideal clock to send to the audio processor to minimize jitter at the DACs. Reduced jitter at the DAC reduces distortion. Lumagen has many reports of the 5XXX significantly improving audio due to this ultra-low jitter HDMI output.

Reference quality colorimetry is often overlooked as part of a high-end home theater. The Radiance Pro can provide automated video equalization, using third party calibration software, with more accuracy than calibration without a 3D LUT. Using the Radiance Pro’s DTM, and Color Management System, you can See what the director intended™.

Other features include image-based instant-auto-aspect detection and selection for HD, 3D, and 4k UHD and HDR sources. Anamorphic support with, or without, an anamorphic lens. Image based auto-aspect selection, plus precise geometry adjustments including size, and masking, are available. The Radiance Pro’s Non-Linear-Stretch (NLS) feature allows the user to stretch 16:9 content to fill an anamorphic screen using their preferred settings. For 16:9 screens and TVs, an anamorphic image can be placed anywhere in the active screen area, or with zoom, and/or cropping, can fill a larger portion of the screen. Multiple configuration memories allow for different independent configurations, such as day, night, sports, and black-and-white.

The adaptability of the Radiance Pro is second to none. Using Field Programmable Gate Array (FPGA) technology, the Radiance Pro can add hardware image processing and setup features long after installation. The Radiance Pro is adding new features over time. One example is HDR Dynamic Tone Mapping was added four years after product introduction and is available to all Radiance Pro owners by simply updating to the latest free release.

Finally a Cooling Blanket That Actually Works for Hot Sleepers
Size: Queen (90" * 90"）, Color: Luxury Grey, Size: Queen (90" * 90"）, Color: Luxury Grey
I first got to know this brand when they released their cooling pillow. At the time, I was very skeptical because I’ve tried many “cooling” pillows and pillowcases from other brands, and almost all of them failed to stay cool throughout the night. Surprisingly, this brand was the first one that actually worked for me. Going through menopause has been extremely difficult, especially dealing with the constant heat and night sweats. I kept thinking that if they could somehow use the same cooling technology in a blanket, it would be amazing — and they actually did it. This blanket has honestly been a lifesaver for me. One side has the cooling fabric while the other side feels more like a regular blanket, so you can switch depending on the temperature or season. I’ve been using a silk comforter before this, and while it was comfortable, it really didn’t help much with overheating at night. This cooling blanket made a noticeable difference almost immediately. What impressed me most is that the cooling effect doesn’t just disappear after a few minutes. It stays comfortably cool and lightweight through the night without feeling damp or overly thin. Since using it, I’ve actually been tracking improvements in my sleep using my WHOOP device, and over the past 20 days I’ve noticed my deep sleep readings improving consistently. The blanket also feels well made, soft, and lightweight without feeling cheap. For the quality and performance, I think the price is very fair, especially compared to other “cooling” bedding products that overpromise and underdeliver. If you struggle with hot sleeping, night sweats, or menopause-related heat issues, I would absolutely recommend giving this a try. It genuinely improved my sleep quality.

Great blanket for keeping cool, but doesn't magically defy physics.
Size: King（103“*90”）, Color: Luxury Grey
This blanket is pretty awesome, and functions exactly as stated; however you might get the wrong impression from the image of the blanket in a the snowy mountains glowing blue as if its actively cooling. The blanket has two sides, the "cold" and "normal" side -- the cold side is the one that has the Q-max 0.45 effect, it actually feels cool to the touch. That being said, covering yourself with this blanket feels pretty similar to using a down blanket with a silk (or some cooler) fabric. It feels quite cool initially but eventually your body puts out enough heat and it "runs out" of cooling. Although this blanket doesn't magically actively generate cooling, its quite effective because it operates fundamentally differently from most blankets. Most blankets are engineered to keep you warm by trapping heat in; this blanket is explicitly designed to draw heat away from your body. As such, it is extremely effective if you use a fan or run the AC, because your body heat is drawn away from the top surface and the inner surface can "grab" and remove more heat. As you probably know, air is a great insulator so this blanket has to be making contact with your body to achieve the cooling effect. If you are familiar with the way "Under Armor" works, I believe this blanket uses a similar principle to keep you cool. This blanket is quite light weight and comfortable, with a very silky (polyester) feeling outer surface. I have not owned this for a year yet, but I'm quite confident that this blanket would be suitable for winter (in Southern California); except if you live in a snowy region. 5/5 for a somewhat high tech blanket that keeps you cool; its the best in cooling you can get without resorting to "active" cooled blankets such as ones with water circulation.

Fascinating product.
Size: Twin（90“ * 67”）, Color: Luxury Grey
It is a nightly struggle. My wife is a hot sleeper. I am not. It’s resulted in more than one argument. One of us is usually left shivering or sweating. So when Amazon offered to send me this cooling blanket, I thought I would give it a try. I’m really glad that I did. This item arrived well packaged and in good condition. It is lightweight and made of a polyester type material. The stitching is strong. The first test was the washing machine. We washed it with cold water on the gentle cycle. We then line dried it. It held up fine. We have a king size bed, but I decided to get a twin sized blanket. I put a warm blanket on my side of the bed and the cooling blanket on her side of the bed. It worked brilliantly. I don’t know what the science is buying these blankets, but it really does lower your body temperature. The moment that you open the package and feel the blanket, you’ll realize that it has some sort of cooling gel inside of it or something that draws heat away from you. Suffice it to say that our first night with this product was one of the best nights sleep that both of us had. If you have a problem like this, I would definitely recommend this blanket as a viable solution. In terms of value, I understand that this is not cheap; however, ask yourself what the value is of a good nights sleep. Overall, I’m very pleased with the quality, design, and functionality of the cooling blanket. I would definitely recommend it.

Cooler than my thinner blankets
Size: Queen (90" * 90"）, Color: Luxury Grey
This is a really nice cooling blanket—silky, soft, and comfortable. I actually tried it on a cold day (classic flip flip Rocky Mountain weather where it swings from 90° to 30° overnight), and it was absolutely freezing, lol. On warmer days, I can clearly tell that it's cooler than even my thinner blankets. My husband tends to sleep hot, and this works great for him. I run cold; it can feel a bit too cool initially, but that fades after a few minutes and stays comfortable. I also have two cats and was worried they’d snag it right away. We keep their nails trimmed, but they’re still cats. So far (about a week in), no snags or pulls—but I’ll update if that changes since that’s a big factor for me. At almost $100, it’s definitely not cheap for a blanket. I think it makes the most sense if you’re a hot sleeper or deal with night sweats—then the cooling effect feels more worth it. If you tend to run cold, it might feel like overkill unless you specifically want something for summer. Overall good value for a nice quality cooling blanket.

Surprisingly strong cooling effect and really comfortable
Size: Queen (90" * 90"）, Color: Luxury Grey, Size: Queen (90" * 90"）, Color: Luxury Grey
This comforter honestly impressed me more than I expected. The cooling effect is very noticeable right away. Like actually noticeable, not just one of those things brands say. When you first touch it, it feels cool to the skin and that feeling sticks around instead of fading instantly. I’ve been using it at night and it definitely helps with overheating. I tend to get cery hot when I sleep, also I’m pregnant right now so that makes it even worse, and this has made a difference. It feels lightweight but still cozy enough that it doesn’t feel like you’re just using a thin sheet. The fabric is really soft and smooth, also it lays nicely on the bed without feeling stiff or bulky. It gives that clean, almost silky feel without being slippery. One thing to keep in mind is it’s not a super thick comforter, but i will say there is some heft to it. Like if i wrap myself around in it, it has some weight to it. Overall, I’m really happy with it. It actually does what it claims with the cooling, and it’s comfortable enough for everyday use. Great option if you’re a hot sleeper or just want something lighter and refreshing at night.
