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)

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.

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 [email protected] (3.7 watts). On the dimmest setting, it was drawing [email protected] (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.

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!

I recently installed the Luminoodle behind my monitor and have been using it for several weeks now. In general, I’m very pleased with the results, but there are a couple of caveats worth noting. What I like: • Setup was extremely straightforward: peel-and-stick adhesive, plug into USB and go. The installation hardly took any time. • The ambient backlight makes a noticeable difference in how my screen looks in a dim room. It improved the perceived contrast and I personally feel less eye fatigue when working late at night. • The USB power input is a big plus (no dedicated adapter needed), so it fits nicely behind my monitor desk-setup.

By far the best backlight. I’ve tried others but none are as good. Changed my tv and bought these again for the new one. A nice bonus was the leds came off perfectly from the old tv with no sticky residue. The light strip is very well designed with cutouts every few cm which allows it to bend around corners - very clever! The light it gives is a lovely clear white which boosts the image on the tv. Can’t fault them. There’s no fancy colours or dimming etc but there Shouldn’t be for bias lighting.

Cumple perfectamente para pantallas de hasta 32". Buen adhesivo y muchas opciones de configuración.

Livraison rapide, bien emballé, installation facile, colle très bien. Pas de télécommande, s'allume quand on allume la télé puisque branché par clé USB. Lumière blanc froid, très belle lumière, n'ébloui pas, très beau rendu lorsque votre télé se trouve dans un coin, met le coin en valeur

I love this! For years I've had a desk lamp shining on the wall behind the TV as it always made viewing easier on the eyes and the picture look better. Finally got this and am amazed!! Beautiful glow and easy to install. I have a 50 inch set and the large size for a 30 to 40 inch fits perfectly all the way around. The Luminoodle stays on for 15 seconds after I turn the TV off. You will not regret getting this!!!

Perfectly lights up the room and eases the effect of a bright screen in a dark area. Love the brightness (it gets pretty intense), the colors, the remote, install was easy, adhesion is solid, all LEDs are working perfectly.
