Save Space ＆ Simple operation
USB Plug
The USB plug will not occupy other socket space. And you can string up multiple strips onto a small USB switch and only use one power outlet. You will love the flexibility of the USB option which could be for computer/laptop, for the car adapter, even for outside if you got a power bank.
Dimmable
There is a dimmer switch that will dim the entire chain in steps as you hold the switch so a wall dimmer wasn't required.
Note: This product does not have a motion detection feature.
Memory Function ＆ Eye protection
After adjusting the brightness to a comfortable brightness, reading light will not change the next time it is turned on.
The desk light color quality is quite pleasing and there will be no screen flicker, which not only protects the light bar, but also protects your eyes.

Frequently Asked Questions
Will the JUSJUBR light bar give me enough bright, even light for hours of laptop work without eye strain?
Yes. The 12-inch bar runs 33 LEDs producing 400 lumens with a 10–100% touch dimmer, so you can tune brightness to match your screen and ambient room. The cool white setting (around 6000K) reduces eye fatigue during long focus sessions, and the slim bar spreads light evenly across your keyboard and notes without hot spots.
Does the memory function really save my last brightness so I can sit down and start working immediately?
Yes. The built-in memory function recalls the last brightness level and color temperature you used, so the light comes back exactly the way you left it. No tapping through settings every time you power on — just plug into your USB port and the workspace is ready.
Can I link multiple bars together to light a long desk or a full counter without losing brightness at the end of the run?
Yes. The linkable connector system supports bundles up to 6×12 inches on a single USB power source. The full 6-bar run draws 12 watt-hours and delivers consistent end-to-end brightness, so the last bar is just as bright as the first — ideal for L-shaped desks or long workbenches.
Is USB power stable enough for daily 8-hour work sessions, or will my laptop complain?
The light draws 5V USB at a low, steady current that any standard USB-A port, wall adapter, or power bank can handle. It will not drain a laptop battery quickly and will not trigger USB power warnings, making it safe for all-day use in a work-from-home setup.
Will the cool white color temperature actually help me stay alert and focused during afternoon work slumps?
Yes. Cold white light (roughly 6000K) has been shown to support alertness and concentration. The three-temperature selector lets you switch to cool white for deep-focus tasks and back to warm white when you wind down — one bar, two modes of productivity.
What kind of USB power source do I need, and will my existing laptop port work?
Any standard 5V USB-A port works — a laptop, a phone wall adapter, or a 10,000mAh+ power bank. The light is engineered for low-draw 5V input, so you do not need a fast-charge brick or a special adapter. Most users plug directly into their laptop, monitor USB hub, or the spare phone charger they already own.
Is this light bar bright enough to replace my main desk lamp for reading and paperwork?
For most desk sizes, yes. A single 12-inch bar puts 400 lumens right where you need it — across a keyboard, notebook, or textbook. For larger desks or two-monitor setups, link two or more bars end-to-end on one USB port to cover the full surface.
Will the slim 0.22-inch profile get in the way of my monitor, keyboard tray, or desk accessories?
No. At 0.22 inches tall and 0.67 inches wide, the aluminum profile sits almost flush against the underside of a shelf, cabinet, or monitor riser. Most users forget it is there, and it leaves full clearance for monitor arms, keyboard trays, and desk organizers.
How does this compare to a traditional swing-arm desk lamp for productivity?
Unlike a swing-arm lamp, the JUSJUBR bar delivers shadow-free, even light across the whole desk surface rather than a single hot spot. It also frees up desk space, has no bulky base, and runs off USB — so you can route it under a shelf or monitor riser for a cleaner, more focused work zone.
Can I leave it on for hours while I work without it overheating or buzzing?
Yes. The LED design produces very little heat even after 8+ hours of continuous use, and the solid-state electronics have no buzzing or flicker at any dimming level. It is rated for long daily use in home office environments.
I work in a small apartment with limited outlets — will USB power really be enough?
Yes, and that is the main advantage. Because the bar runs on 5V USB, you can power it from a laptop, a monitor's USB hub, a phone charger, or a power strip you already own. It does not compete for a wall outlet with your monitor, laptop charger, or other desk gear.
I get distracted by clutter — does the wire-free, stick-on install actually stay clean?
Yes. The peel-and-stick adhesive mounts the bar with no visible screws, no cord channels, and no driver box. The thin USB cable can be tucked behind a monitor leg or along a desk edge with the included cable clips, leaving a clean, distraction-free surface.
What if my setup changes — can I move the bar to a new desk or apartment without damaging the surface?
Yes. The adhesive removes cleanly from most smooth surfaces with a little heat from a hair dryer. You can remount it on a new shelf, cabinet, or monitor riser using fresh 3M strips (sold separately), making it ideal for renters and people who rearrange often.
How do I install the JUSJUBR under-cabinet light bar?
Installation takes about two minutes. Wipe the underside of the cabinet, shelf, or monitor riser with a clean dry cloth to remove dust and grease. Peel the backing off the included 3M adhesive pad, press the bar firmly into place for 30 seconds, and plug the USB cable into any 5V USB power source — a phone charger, laptop, monitor USB hub, or power bank. The bar is ready to use immediately.
Can I link multiple bars together, and how many can I run on one USB port?
Yes. The bars use a simple inline connector on the end cap — slide the connector into the next bar until it clicks, no tools required. You can run 1×15", 2×12", 4×12", or 6×12" bundles from a single 5V USB power source. The full 6-bar run delivers consistent brightness end-to-end and draws only 12 watt-hours, well within standard USB power output.
How do I switch between warm, natural, and cool white?
Tap the touch sensor on the end cap to power the bar on, then press and hold the sensor to cycle through the three color temperatures. The bar remembers whichever color and brightness level you used last, so the next time you turn it on, it will return to that exact setting without any re-adjustment.
Will this work with my phone charger, power bank, or laptop USB port?
Yes. The bar accepts any standard 5V USB-A power source that supplies at least 1A of current. That includes virtually all phone wall adapters, laptop USB ports, monitor USB hubs, and 10,000mAh+ power banks. A USB-C to USB-A adapter (not included) can be used with newer USB-C-only chargers and laptops.
Is it compatible with smart plugs, USB timers, or wall outlet USB ports?
Yes. The bar will power on and off automatically when the connected USB outlet is switched, so it works seamlessly with any standard smart plug, USB wall outlet, or USB timer switch. This is an easy way to add a daily on/off schedule or voice control via a smart plug ecosystem.
What is included in the box, and what do I need to buy separately?
In the box you will find the 12-inch LED light bar, a USB power cable, peel-and-stick 3M mounting adhesive (pre-applied or included), linkable connector(s) for multi-bar setups, and cable management clips. The only thing you need to supply is a USB power source — a phone charger, laptop, or power bank — and optionally a USB-C adapter if your charger is USB-C only.
Is this light bar safe to use every day, and how long will the LEDs last?
Yes — it is rated for continuous daily use. The LEDs are engineered for tens of thousands of hours of operation, which for typical use (a few hours per day) translates to many years of service. The cool-running LED design, constant-current driver, and 5V low-voltage input make it safe for daily use in kitchens, closets, desks, and workbenches with no special precautions.
Can I cut the bar to fit a shorter space, or extend it with a longer cable?
The bar itself is a fixed length (12 or 15 inches depending on the bundle) and should not be cut, as that would damage the LED array and void the warranty. For shorter spaces, simply mount the full bar and let the extra length extend past the work area. The included USB cable is 3 feet long; for longer runs, any standard USB extension cable can be used in line with the power source.
What is the difference between an LED light bar and an LED light strip for under cabinets?
An LED light bar is a rigid aluminum housing with a fixed LED array and built-in driver, designed for stick-on or screw-mounted installation. An LED strip is a flexible ribbon of surface-mount LEDs that requires a separate driver and is typically adhered directly to a surface. Light bars deliver more consistent brightness, better heat dissipation, a cleaner look, and easier linkable expansion; strips are cheaper but often have visible hotspots, adhesive failure over time, and require a separate bulky driver.
