6 Best TV Backlights for 100 Inch TVs of 2026
Six TV backlight kits listed for 98 to 100 inch screens, from 23 foot USB strips to camera sync kits, compared on strip length, coverage, and control.
By Ethan Cole
Updated October 28, 2026
A 100 inch TV has an outer edge of about 22.7 feet, and that single number rules out most backlight kits. Kits made for 75 to 85 inch screens stop at 16 to 18 feet, and on a 100 inch set they leave a bare side or a loop far in from the edge. This guide compares six kits whose makers list them for 100 inch TVs, with strips from 20.3 to 24.6 feet.
The field is small. The kits with the longest rating histories are USB strips that glow in a chosen color or react to sound. Camera kits that follow the picture exist at this size, but they have far fewer ratings so far. For 70 to 85 inch screens, see TV backlights for large TVs, and for all sizes, our main guide to the best TV backlights.

Top 3 TV Backlights for 100 Inch TVs Reviewed
#1 Daymeet 23 ft TV LED Backlight for 75 to 100 Inch TVs: Best Overall
Why We Picked It
Daymeet’s 23 foot strip has the top WikiHomeLED Score among 100 inch kits, 4.5 stars on more than 6,900 Amazon ratings at the time of review. Amazon pools that count with the smaller sizes of the same strip, so read it as the rating history of the product line.
At 23 feet it is slightly longer than the 22.7 foot edge of a 100 inch screen, enough for a full loop mounted just inside the edge. It is an ICRGB strip, so it shows several colors along its length at once, with a built-in microphone for music mode. It runs on 5 V USB, and you control it with the douCo StripX app or an IR remote. It does not read the picture.
Key Specifications
- Listed TV size: 75 to 100 inch
- Strip length: 23 ft
- LEDs: ICRGB (multi-color segments)
- Control: douCo StripX Bluetooth app, IR remote
- Power: 5 V USB
- Rating: 4.5/5 from 6,973 Amazon ratings, pooled across sizes (October 2026)
| Pros | Cons |

Things to Consider
A 23 foot strip draws more current than a short one. It runs on 5 V USB, so if the TV’s port is not convenient, a USB wall adapter works too; the strip will then no longer switch off with the TV.
Best For
Owners of 85 to 100 inch TVs who want full coverage and multi-color effects at a low cost.
Skip It If
Skip it if you want the lights to follow what is on screen.

#2 maylit 24.6 ft ICRGB TV LED Backlight for 85 to 100 Inch TVs: Longest Strip
Why We Picked It
The maylit strip is the longest here at 24.6 feet, and it is listed for 85 to 100 inch TVs. It scores 4.3 stars on more than 10,400 ratings, again pooled with other sizes of the line.
Its 24-key IR remote covers more than most: 10 brightness levels, 10 basic colors, an off timer, a night mode, and four music modes. The strip comes as one roll with corner connectors, which helps at the sharp corners of a large TV, and maylit includes both double-sided tape and fixing buckles. It runs on 5 V from the TV’s USB port and turns on and off with most TVs.
Key Specifications
- Listed TV size: 85 to 100 inch
- Strip length: 24.6 ft, one roll with corner connectors
- LEDs: ICRGB
- Control: 24-key IR remote, app
- Remote features: timer, night mode, 4 music modes
- Rating: 4.3/5 from 10,464 Amazon ratings, pooled across sizes (October 2026)

Things to Consider
The listing does not state where the strip can be cut. On a 98 inch TV, plan where the extra length will sit before you stick the first section down.
Best For
The largest screens, 98 to 100 inches, where you want certain four-side coverage.
Skip It If
Skip it if your TV is under 85 inches; a shorter kit will fit better.

#3 KANTUTOE 23 ft TV LED Backlight for 70 to 100 Inch TVs: Widest Size Range
Why We Picked It
KANTUTOE lists this 23 foot strip for anything from 70 to 100 inches, the broadest range here, which helps if you may move to a bigger TV later. It scores 4.3 stars on more than 9,200 ratings, pooled with the brand’s shorter strips.
It reacts to sound through a built-in microphone, offers more than 20 dynamic modes, and dims through the remote or a Bluetooth app. KANTUTOE uses a small receiver that hides behind the TV, plus foam adhesive and clips to hold the strip.
Key Specifications
- Listed TV size: 70 to 100 inch
- Strip length: 23 ft
- Control: remote, Bluetooth app
- Modes: 20+ dynamic modes, music sync
- Mounting: foam adhesive plus clips
- Rating: 4.3/5 from 9,211 Amazon ratings, pooled across sizes (October 2026)

Things to Consider
On a 70 to 75 inch TV, 23 feet is several feet longer than the screen’s edge, so you will need to trim it or run the extra along the bottom. A kit sized for that range is a cleaner fit, see TV backlights for large TVs.
Best For
Buyers with a 98 or 100 inch TV now, or a plan to move up to one.
Skip It If
Skip it if you want screen sync or a strip sized exactly for a 75 inch TV.

How to Choose TV Backlights for 100 Inch TVs
Measure the Edge, Not the Diagonal
A 16:9 screen’s edge is about 2.7 times its diagonal: about 22.2 feet at 98 inches and 22.7 feet at 100 inches. Mounted 2 to 3 inches in from the edge, a full loop needs about 20.2 to 21.4 feet. Anything shorter will leave a gap or sit far inside.
Rating History Is Thin for Sync Kits
At this size the long-running products are USB strips. Camera kits for 90 to 100 inch TVs are newer, and the LAVON kit has only 22 ratings. If screen sync matters most, buy from a seller with an easy return window.
Power for Long Strips
Long USB strips draw more power than short ones. If a strip looks dim at the far end or flickers on the TV’s USB port, a 5 V USB wall adapter can help, but then the strip will not switch off with the TV.
Corners and Mounting
Large TVs often have deep backs and bulges. Corner connectors (maylit) or clips (KANTUTOE) keep the strip flat at turns. Keep the strip and controller clear of the TV’s vents.
Projectors Are a Different Case
These kits are built for TVs. A projector screen has no back to stick a strip to, and none of these listings covers that use.
How We Evaluate TV Backlights for 100 Inch TVs
We did not install these kits. We compared manufacturer specifications and Amazon listing details and ranked the products by the WikiHomeLED Score, which adjusts the Amazon star rating for the number of ratings (ratings checked October 29, 2026). Amazon pools ratings across sizes of one product, and we say so where it applies. To qualify, a kit had to be listed by its maker for 98 or 100 inch TVs, have a strip long enough for that size, and have at least 20 ratings. We left out two kits whose listings say they cover only three sides or three quarters of a 100 inch screen, and one whose listing gives conflicting lengths. Screen edge lengths are calculated from the 16:9 screen shape. The full method is on our How We Review page.
Frequently Asked Questions
How many feet of LED strip do I need for a 100 inch TV?
The screen edge is about 22.7 feet. Mounted a couple of inches in, a full loop takes about 21 feet. That is why kits for 100 inch TVs run 20 to 25 feet.
Will a 75 to 85 inch kit fit a 100 inch TV?
Not all the way around. Those kits are usually 16 to 18 feet, several feet short of a 100 inch screen’s edge, so one side will be bare.
Are there camera sync kits for 100 inch TVs?
Yes. LAVON, FFJ, and KANTUTOE list camera kits for screens up to 100 inches, but they have far fewer ratings than the USB strips so far.
Can I join two shorter kits?
Only if the maker says the strips can be connected. Most USB kits have one controller per strip, so two kits would run as two separate lights.
Final Verdict
For a 98 or 100 inch TV, the Daymeet 23 foot strip has the best rating history and enough length for a full loop. Choose the maylit for spare length and a sleep timer, and the KANTUTOE 23 foot strip if you want room to move between sizes. If you need the lights to follow the picture, the FFJ three-sensor kit has more ratings than the LAVON, but both are newer products.
