Ten silicone light arms fan out from a hub on a 60in stem, and the IC chips inside run colour up each one so the wall looks like a rocket bursting over and over, in time with the music.
The DTQJ smart firework is a light show you stick to the wall. A 60in stem climbs like the trail of a rocket, and at its top a small hub board sends out ten shorter arms in a starburst. Each arm is a flexible silicone strip packed with RGB LEDs and IC chips, so colour can race outwards along it rather than simply switching on and off.
That IC detail is what sells the illusion. On a plain RGB strip every LED shows the same colour at once; here each segment gets its own instruction, so a spark of gold can shoot up the stem, bloom at the hub and then fade outwards in pinks and blues. With over 200 effects stored, the burst never has to look the same twice in an evening.
The silicone strips bend, so the arms do not have to sit in a perfect ring. Curl a few for a looser, drooping willow firework, or keep them straight for a crisp chrysanthemum shape. A slight curve near the tips looks especially natural when the colour trails off.
Because it runs from 5V USB, the whole thing can hang wherever a charger reaches: over a bed, above a desk, on the wall behind a gaming chair. It is a decoration first and a room light second, so treat it as the sparkle and keep a lamp for reading.

Switch on mic mode in duoCo StripX and the controller's built-in microphone takes over. Bass hits send bursts up the stem, a quiet chorus lets the colours settle, and a big film explosion lights the whole wall. It works with any sound in the room, so there is no cable to run to the speaker.
Moments where the DTQJ firework earns its place:
The timer is more flexible than most. DTQJ lets you set daily, weekly or one-off schedules, or a countdown that shuts the lights down after the party winds up. Set it to glow at dusk and switch off at bedtime and the burst becomes part of the room's routine.
Keep expectations in line with what it is. It is an indoor decoration without water resistance, so skip porches and bathrooms. The adhesive wants a clean, smooth, dry wall; textured plaster or wallpaper that peels will let the arms droop. And while it glows prettily, it will not light a whole room for reading.
The two DTQJ sets share the same 60in stem and ten arms; only the arm length changes. With 19.6in arms, the burst spans roughly 40in across from tip to tip, big enough to dominate a bedroom wall. The 11.8in arms give a burst of about two feet across, a better fit above a desk, a headboard or a narrow stretch between windows.
A quick way to choose:
Fitting takes minutes, but a plan helps the shape come out even:
Skip the phone's Bluetooth settings entirely: the firework's controller is found and linked by duoCo StripX itself, as with every ELK-BLEDOM-style light. If the app sits empty, the pairing steps cover the usual fixes; mic mode, effects and timers get their full treatment in the app guide.
The 24-key remote and the 3-button control box are there for guests and quick changes. Hand the remote to whoever is running the party and keep the app for building a custom scene.
Firework lights are a small family on the ELK-BLEDOM side, and they look alike at first glance. The differences sit in arm count, arm length, the app and the remote. DTQJ's pitch is choice: two arm lengths, a flexible schedule timer and a design that runs from any USB charger.
| Light | Arms | App | Remote |
|---|---|---|---|
| DTQJ smart firework | 10 x 19.6in or 10 x 11.8in, plus 60in stem | duoCo StripX | 24-key |
| Daymeet smart firework | 10 x 20in, plus 60in stem | duoCo StripX | 24-key |
| FanGera firework light | 13 x 19.7in, plus 59in stem | Magic Lantern | 40-key |
| ZOKON 3D cloud | Cloud, not arms | duoCo StripX | 2.4G music remote |
The Daymeet smart firework is the closest twin in size and app. The FanGera firework packs three extra arms for a denser burst and runs on Magic Lantern instead. For a different kind of ceiling drama, the ZOKON cloud flashes lightning to the beat.
Between the two duoCo StripX fireworks, the choice comes down to size and timing. DTQJ offers a compact 11.8in version, which suits small rooms where a 40in burst would crowd the wall. Its schedule timer, with weekly and one-off settings, also helps anyone who wants the burst to switch on by itself before guests arrive and fade out once the party is over.
Before buying, check:
With 19.6in arms the burst is roughly 40in across; with 11.8in arms, about two feet. Both sets add a 60in stem below the hub.
No. It runs on 5V USB and DTQJ leaves the adapter out, so use a phone charger, a USB wall plug or a power bank.
Yes. The controller has a built-in microphone; switch on mic mode in duoCo StripX and the colours move with any sound in the room.
duoCo StripX on iPhone or Android. The 24-key remote and the 3-button box on the cable work too.
