desertcart.com: Power Practical LED Lights for TV Backlight, USB Powered TV LED Light Strip W/Bias Ambient Lighting for Home Theater, True White, Size (30"-40” TV) : Tools & Home Improvement

Review: Simple, easy to use TV bias lighting - This is the third time I've bought this LED strip. I keep coming back to this one because it's simple to use, reliable, and cheap. I've tried other bias lights with dimming features and color control and they are just complicated for no reason, the remote runs out of battery and the batteries are not standard size. I don't need any of those features for a TV bias light. This one has no on-off switch, no dimmer control, no color control. You plug it into a USB port on the back of the TV and it turns on and off with the TV. Simple and no fuss. In terms of sizing, I've used this on a 65", 85" and now 98" TV. For the 98" TV, I bought the XXL length. As you can see from the picture, I did not run it to the very edge of the TV. It sits about 12" inboard on all sides. That works perfectly in my view. I have tried running the light strip very close to the edge of the TV and it's too bright and distracting. I like my bias lighting to be subtle and plain, D6500 white. For Sony TVs, they will sometimes send power to the USB port when the TV is turned off. To keep the bias light off with TV off, I have installed a USB power switch so I could just shut it off. Not a big deal and much simpler to use than the janky remote controls that comes with the color changing lights that are easy to lose or runs out of battery power after a year or so.
Review: Very Good Quality. Bright. Cooler Color Temp. Power Within USB 3 Spec - Works great. My only complaint is that the light is more blueish, while I prefer a more reddish (lower, “warmer” temperatures). I knew this going in, and for me, the convenience of the optional RF dimmer switch and the USB power trump this minor complaint. I installed the 118” “Large” Luminoodle kit on a Vizio P55-c1 (55” 4K TV). I installed in on the back where the back was parallel with the wall behind it. Because the rear of my TV is slightly curved around the edges (~5” radius), the “flat” area that I applied it to ended up being about 3” in from the left, right, and top. If you’re unsure what size you need, measure out a piece of string and see how well that would work. Note also the connector length when considering placement. It’s a very thoughtful design, with a flat cable and bi-directional USB connnector. The adhesive is genuine 3M OEM molding tape. This is the stuff they use in the automotive world to e.g. stick the chrome model name of the car onto the car. Trust me, it’s what you want. Once applied (you peel the red tape off from the grey adhesive, which itself is stuck on one side to the back of the flexible Luminoodle circuit board), it’s not going anywhere until you want it to. As long as you have clean hands and a clean surface (dust the back of your TV before applying the Luminoodle), you’ll be able to re-stick it as long as you’re careful if you mess up initially. Again, it’s the best stuff that they could have possibly used. Measure it out and plan where you want to install it before you go to stick it on and you’ll do well. I also went for the optional RF dimmer switch, which is equally great, and shares the flat cable + bidirectional USB connector (you can plug it in “backwards” and it works fine). I control it using a Broadlink RM-Pro, which is another IMO very good product. The RF range is good, there are MANY brightness levels, and the interface is simple. As some of you have been, I was curious about the actual power draw for the large size. I measured using two genuine Apple 110v USB adapters - the 5W iPhone adapter and the 12W iPad adapter. With the dimmer on full bright, the 118” Large Luminoodle drew 0.71A@5.16v (3.7 watts). On the dimmest setting, it was drawing 0.04@4.97V (this was running through a USB 3 extension cable into my TV’s USB 2.0 port -> tester -> dimmer on lowest setting -> Luminoodle). TL;DR a USB 3.0 port should be able to provide 900mA of power at 5v. This draws less than that in all circumstances for the large size, even with the dimmer. If your TV has a USB port that is blue inside, this will work as bright as it can possible go. If you only have USB 2.0, there’s a small chance that your TV will complain about the device drawing too much power for the Large size (not sure if other sizes draw less power, but they *should*) and you’d have to potentiallly use a USB wall adapter or something.

### ⭐⭐⭐⭐⭐ Bias lighting is amazing
*by J***1 on August 3, 2025*

This bias lighting is amazing, it's a totally new way to watch TV. Colors are deeper, the darks are darker, it makes it easier on the eyes. Installation is simple and only took 10 min. I just wish my TV turned the usb off when I switch off the TV. Great product and price!
