A small receiver box and remote that plug into an ordinary 4-pin RGB strip and give it a phone app, timers and a microphone, so an old strip with a lost remote dances again.
Every drawer seems to have one: a perfectly good RGB strip whose little remote vanished or whose controller gave up. The Sunity set is the fix. It is a Bluetooth receiver box with an IR remote that slots in where the old controller was, then adds a phone app and a microphone the strip never had.
It works with the most common strip there is: the 4-pin, 10mm-wide RGB type built on 5050, 3528 or 2835 LEDs. Those four pins are one power line and three colour channels, red, green and blue. The controller mixes those three channels into any colour, so the strip holds a single shade along its full length, just as it did before.
What the set adds to an old strip:
The strip keeps its own power supply, since none is included. Plug the old adapter into the Sunity box, the box into the strip, and the strip wakes on a new brain. The box handles 5V, 12V and 24V strips, so the same set suits a USB TV strip or a 24V room reel. Nothing about the strip changes, so any mounting you already did stays exactly where it is.

Hooking the Sunity box up takes about a minute, and one detail decides whether it works first time. The controller's strip lead has an arrow printed on it. That arrow must line up with the '+5V/12V/24V' mark on the strip.
The step-by-step:
The 2-port version drives two strips from one box, each on its own lead, and both show the same colour. Sunity recommends no more than 10m (32.8ft) of strip per port, which covers most bedroom and TV runs. Beyond that, a reel starts to dim toward the far end as voltage drops along the copper.
A strip of adhesive tape is included for the receiver box. Stick it where the remote can see it, since infrared needs line of sight, and where its mic can pick up the room.
Behind a TV, the rear of the stand or the wall just under the screen works well. In a bedroom, the top of a headboard or the side of a shelf keeps the box out of sight but still in the remote's view.
The Sunity box speaks the same Bluetooth language as the ELK-BLEDOM family of light controllers, which is why phones often list lights like this under names that look like speakers. It is a light controller, not an audio device. On iPhone, Sunity points to LotusLanternX in the App Store; on Android, Lotus Lantern in Play Store.
The manual's QR code or a quick store search gets the app installed. With Bluetooth on, the controller links itself as soon as the app opens. Adding it under the phone's Bluetooth settings does nothing for a light, so leave that screen alone. The ELK-BLEDOM pairing walk-through has the fixes for the usual snags.
With the app open, the old strip picks up these tricks:
The microphone is the real upgrade. A strip that used to glow one colour behind the TV now pulses with the soundtrack, or flickers along to a party playlist from a speaker across the room. Turn sensitivity up for quiet music and down for loud rooms, so the strip reacts to the beat rather than every sound.
The ELK-BLEDOM app page compares Lotus Lantern with duoCo Strip and Magic Lantern, handy if you run several lights from different makers.
A Sunity controller makes sense when the strip itself is fine. If the LEDs are dim, the adhesive has failed or some sections no longer light, a new kit with its own controller is usually the better night's work.
| Situation | Better choice |
|---|---|
| Strip works, remote or controller lost | Sunity controller |
| Two short 4-pin strips to run together | Sunity 2-port |
| Strip dim, peeling or half-dead | A new strip kit |
| Want rainbow chasing | An RGBIC strip with its own controller |
Pick between the two Sunity versions by counting strips. The 2-port box runs two reels, for example one behind the TV and one under the sofa. The 1-port box suits a single strip and keeps the wiring even simpler.
One more reason to choose the Sunity route: the strip stays on the wall. Peeling off an old strip and sticking up a new one is the messy part of any lighting job, and a controller swap skips it entirely.
If a fresh start wins, a few kits stand out:
Before ordering the Sunity set, run this check:
Strips worth pairing with it are rounded up on the ELK-BLEDOM overview.
It fits 4-pin, 10mm RGB strips at 5V, 12V or 24V using 5050, 3528 or 2835 LEDs. It does not fit RGBIC, RGBW, Govee or Philips Hue strips.
No. Use the strip's original power supply, or a new one with the same voltage.
Sunity points iPhone users to LotusLanternX and Android users to Lotus Lantern. The app handles the link; the phone's settings are not involved.
The strip's colour pins may be in a different order, or the connector may be reversed. Check the arrow sits on the +V side, then remap the pin order in the app.
