9 Best TV Backlights for Large TVs of 2026
Our guide highlights the top 10 TV backlight kits designed to enhance 70-inch and larger screens. We prioritized accurate color sync, seamless smart controls, and kits sized for full edge coverage.
By Ethan Cole
Updated October 21, 2026
Large TVs need longer strips, and that narrows the field: many TV backlight kits stop at 65 inches, and a short kit stretched around a 75 or 85 inch screen leaves bare edges. Every kit in this guide is listed by its maker for TVs of 70 inches or more, with strips from 15 to 23 feet. They split into two groups: kits that follow the picture, using a camera or an HDMI sync box, and simpler strips that light the wall in a color you choose or react to sound.
We compare nine kits, ranked by WikiHomeLED Score, and label which ones follow the screen. For more options, see our TV Backlight Kits category or our main guide to the best TV backlights.

Top 3 TV Backlights for Large TVs Reviewed
#1 CPLID USB TV Backlight Kit: Best Simple Backlight
Why We Picked It
The CPLID kit edges out the Govee below for the top WikiHomeLED Score, with a 4.5 out of 5 average from more than 10,000 Amazon ratings at the time of review. It is built for one job: an 18-foot strip that covers all four sides of a 70 to 82 inch TV, powered from the TV’s USB port so it turns on and off with the TV, and controlled by an RF remote that CPLID lists with a range of up to 60 feet and no need for line of sight.
CPLID states plainly that the lights cannot change with the TV’s colors. You get 17 colors, including white, plus fade and flash modes, and the strip remembers the last color when switched off. There is no app or voice control. If you want a steady glow behind a big TV with as little setup as possible, its rating history makes it the strongest pick here.
Key Specifications
- Strip Length: 18 ft
- TV Size Range: 70 to 82 inch TVs
- Power: TV USB port
- Control: RF remote, listed range up to 60 ft
- Colors: 17, including white
- Rating: 4.5/5 from 10,870 Amazon ratings (October 2026)

Best For
Owners of 70 to 82 inch TVs who want a simple, remote-controlled glow behind the screen and no app to manage.
Skip It If
Skip it if you want the lights to follow the picture, need app or voice control, or have an 85 inch TV. See the CPLID USB TV Backlight Kit.
#2 Govee TV Backlight 3 Lite for 75 to 85 Inch TVs: Best Screen-Sync Kit
Why We Picked It
The 75 to 85 inch version of the Govee TV Backlight 3 Lite (model H6099) shares the top score with the CPLID, with a 4.5 out of 5 average from more than 10,000 Amazon ratings, and it is the highest-ranked kit here that follows the picture. A camera on top of the TV reads the screen, and Govee’s Envisual chip adds fish-eye correction to improve color matching near the edges. Because it reads the screen itself, it works with the TV’s built-in streaming apps as well as external devices.
The 16.4-foot strip uses RGBICW beads, which add a warm white chip to the color mix. It works with the Govee Home app, Alexa and Google Assistant, and DreamView can link up to seven other Govee lights to the effect. The camera uses a gravitational hanging design meant for ultra-thin TVs.
Key Specifications
- Model: H6099
- Sync: Camera with fish-eye correction
- Strip: 16.4 ft, RGBICW
- TV Size Range: 75 to 85 inch TVs
- Control: Govee Home app, Alexa, Google Assistant
- Rating: 4.5/5 from 10,676 Amazon ratings (October 2026)

Best For
Owners of 75 to 85 inch TVs who want the lights to match the picture and like smart home control.
Skip It If
Skip it if you do not want a camera on top of your TV, your screen is under 75 inches, or you only need a steady glow. See the Govee TV Backlight 3 Lite for 75 to 85 Inch TVs.
#3 Govee H6169 TV LED Backlight: Best Smart Strip
Why We Picked It
The Govee H6169 ranks third, with a 4.4 out of 5 average from more than 6,000 Amazon ratings. Its 15-foot RGBIC strip is listed to cover all four sides of 70 to 80 inch TVs and can show different colors in different segments at once. It works with the Govee Home app, Alexa and Google Assistant, and has a built-in microphone with 11 music modes and more than 99 preset scenes.
Govee’s listing states that it does not capture screen colors, so it is a smart strip, not a sync kit. It also needs a 2.4GHz Wi-Fi network. Choose it over the CPLID if you want app and voice control and multi-color effects, and over the 3 Lite if you do not need screen sync.
Key Specifications
- Model: H6169
- Strip: 15 ft, RGBIC
- TV Size Range: 70 to 80 inch TVs
- Control: Govee Home app, Alexa, Google Assistant (2.4GHz Wi-Fi)
- Warranty: 1 year
- Rating: 4.4/5 from 6,448 Amazon ratings (October 2026)

Best For
Owners of 70 to 80 inch TVs who want a smart, multi-color backlight they can control by voice, without screen sync.
Skip It If
Skip it if you have an 85 inch TV, want screen sync, or your router only offers 5GHz. See the Govee H6169 TV LED Backlight.
How to Choose a Backlight for a Large TV
Check the Listed Size Range First
Size ranges in this guide run from 70 to 80 inches up to 75 to 100 inches. A kit listed for 70 to 80 inches will not cover all four sides of an 85 inch TV, and a 23-foot strip on a 75 inch TV leaves extra length to hide or trim. Measure your TV’s perimeter and compare it with the strip length. Ailofy describes its strip as fixed-length to keep the LED layout consistent for screen sync, so for kits like that the size range matters even more.
Screen Sync: Camera, HDMI, or None
Camera kits (Govee 3 Lite, Ailofy, GHPFLOXQY) read the screen and work with any source, including built-in TV apps, but put a camera on top of the TV. HDMI sync box kits (LightingWill) read the video signal directly with no camera, but only work with external HDMI devices. Strips without sync (CPLID, Govee H6169, maylit, KANTUTOE, HAMLITE) cost less and are simpler, but show a color you choose or react to sound, not the picture.
Power on Long Strips
Several strips here, including the CPLID, maylit and HAMLITE, run from the TV’s 5V USB port and switch on and off with the TV on most sets. HAMLITE notes that it needs a 5V 1A USB port and that on/off sync works with most TVs but not all, so check your TV’s USB output before buying a USB-powered kit.
Remote, App, or Voice
RF remotes, like those with the CPLID and HAMLITE, work without pointing at a receiver. IR remotes, like the maylit’s, need a clear line to a small receiver on the cable. App and voice control (Alexa and Google Assistant) are available on the Govee, LightingWill and Ailofy kits.
White Light
If you want a neutral white glow rather than colors, look for dedicated white LEDs. The HAMLITE kit lists separate 6500K white beads, and the Govee 3 Lite adds a warm white chip. Strips that mix white from red, green and blue often look slightly tinted.
How We Evaluate TV Backlight Kits
Our rankings are based on manufacturer specifications, Amazon listing details and buyer ratings, gathered in October 2026. We included only kits whose listings name TVs of 70 inches or larger. Each kit’s position follows its WikiHomeLED Score, which adjusts the Amazon star average for the number of ratings behind it, as explained on our How We Review page. We then compare screen sync, listed size range, strip length, LED type and control options. We have not installed these kits ourselves. We left out one sync kit that had a single rating at the time of review.
Frequently Asked Questions
Can I use a 55 to 65 inch kit on a 75 inch TV?
It will usually leave at least one side uncovered, because the strip is cut to the perimeter of a smaller screen. Buy a kit listed for your TV’s size; every kit in this guide is listed for 70 inches or more.
Which kits here follow the picture?
Four of the nine: the Govee TV Backlight 3 Lite, Ailofy and GHPFLOXQY use a camera, and the LightingWill CST2 uses an HDMI sync box. The other five are color or music sync strips.
Is there a kit for a 100 inch TV?
In this guide, the KANTUTOE 23-foot strip is the only one listed up to 100 inches. It does not follow the picture; it is controlled by app or remote and has a music mode.
Do I need a professional to install a backlight on a large TV?
No. The kits here mount with adhesive and clips and plug into a USB port or a power adapter. On a large, heavy TV, it is easier to install the strip with a second person, especially if the TV is wall-mounted.
Final Verdict
For a simple glow behind a 70 to 82 inch TV, the CPLID USB TV Backlight Kit has the strongest score in this guide and needs nothing more than its remote. If you want the lights to match the picture on a 75 to 85 inch screen, the Govee TV Backlight 3 Lite for 75 to 85 Inch TVs is the best-rated sync kit here. For voice control and multi-color effects without screen sync on a 70 to 80 inch TV, choose the Govee H6169 TV LED Backlight. For screens up to 100 inches, the KANTUTOE 23-foot strip is the only listed option.
