One long 21ft strip that wraps screens from 32 to 85 inches, runs off the TV's USB port and throws a colour halo on the wall that pulses with films, games and music.
Many TV backlight kits top out at 65 or 75 inches. The DTQJ strip runs 21 feet, enough to trace the back edge of screens from 32 to 85 inches, so the glow reaches the corners of a big living-room set instead of fading out halfway along the top. Switch it on and the wall around the TV turns into a soft frame of colour.
A backlight does two jobs. It sets a mood, and it eases the jump from a bright picture to a dark wall, which many viewers find more comfortable for long evenings. The DTQJ strip handles both: a gentle static colour for a film night, or sweeping effects for games and music.
The effects cover a broad range:
The maker describes the colour as multicolour RGB effects. The whole strip runs one controller, so expect the frame to shift colour together in most modes, rather than a precise per-segment rainbow.
Because it runs on USB, the strip can also live off the TV entirely. It lights a monitor, a bed frame or a gaming desk from a laptop or a USB charger. With 21ft to play with, one strip can even outline a desk and the shelf above it.

Twenty-one feet sounds like a lot, and on a 32-inch set it is. The trick is fitting the strip to your screen and trimming or doubling back where needed. Measure the rear panel first, slightly inside its outer edge, since that is where the strip will run.
| Screen size | How the 21ft strip fits |
|---|---|
| 32–43in | Plenty of spare; run it further in or fold the surplus behind the stand |
| 50–65in | A full loop around the back with room to spare |
| 75–85in | A full loop near the edges, where the 21ft length earns its place |
The install is peel and press, and a few habits make it last:
USB power keeps the wiring tidy. Many TVs switch their USB ports off with the set, so the backlight follows the TV without any timer. If yours stays live, use the app's timer or the remote to switch off at night.
Three ways to control the strip come in the box: the duoCo StripX app, a 24-key remote, plus a three-button box on the cable. duoCo StripX belongs to the same app circle as Lotus Lantern, the one that drives ELK-BLEDOM controllers phones mistake for speakers. The DTQJ strip plays no sound; its music side is a microphone.
Install duoCo StripX, power the strip, turn Bluetooth on and open the app; the TV strip lists itself there, and the phone's settings menu never enters into it. If it will not show, the pairing fixes cover permissions and the other common snags.
The app earns its place in three ways:
The 24-key remote is the sofa option. Leave it next to the TV remote for quick colour and brightness changes during a film. That little inline box is the backup for when both the remote and phone are out of reach.
For a film night, pick a deep blue or warm amber at low brightness and switch music mode off, so the frame stays calm. For a game or a party, turn music mode on and let the room react. The ELK-BLEDOM app guide explains how duoCo StripX differs from Lotus Lantern and duoCo Strip.
Place the control box where it can hear the room. Tucked tight behind a soundbar it hears everything; buried inside a cabinet it barely reacts. The mic reacts to how loud the room is, so a late-night film at low volume flickers far less than a Saturday game turned up high.
TV backlights mostly differ in length, which screen sizes they wrap, and whether the colour runs as one block or in segments. The DTQJ stands out on length: 21ft covers screens up to 85 inches, where many kits stop well short.
How it compares with the TV glows people weigh it against:
Choose the DTQJ when the screen is large, when you want one kit that will still fit after a TV upgrade, or when timers with a set colour matter. Choose a shorter kit for a small screen where 21ft is mostly surplus, or a dedicated RGBIC kit if flowing rainbows are the whole point.
Before ordering, check these points:
Smaller-screen halos and room strips are listed on the ELK-BLEDOM welcome page.
Yes. At 21ft it is sized for screens from 32 to 85 inches, with spare length on smaller sets.
Yes. It is USB powered, so a TV, monitor, laptop, USB charger or power bank can all run it.
No. It reacts to sound through its microphone and to the colours and modes you choose, not to the picture.
