Asymmetrical Optical Design
The HIOUME Monitor Light Bar is an 84 LED desk lamp that clamps onto flat monitors between 0.4 and 1.2 inches thick. Its asymmetrical shape directs light downward onto the keyboard and work surface while keeping glare off the screen, making it suited for office workers and home users who spend long hours at a computer. No tools are required for installation.
3 Color Temperatures 10 Brightness Levels
Under sustained use the light bar delivers 10 dimming steps across three colour temperatures: 2800K warm, 4000K natural and 6500K cool white. The 84 LEDs split evenly between 42 warm white and 42 cool white emitters, and a CRI above 95 Ra keeps colour rendering consistent during extended sessions. A built-in memory function restores the last brightness and temperature setting after power cycles.
USB Powered Aluminium Alloy
The unit draws 4 watts from any 5V USB port on a computer, monitor, charger or power bank. Its aluminium alloy body measures 15.7 by 0.93 by 0.78 inches and weighs 1.1 lb, dissipating heat passively without a fan. Rated LED lifespan exceeds 100,000 hours. The light bar is not compatible with curved monitors.

Questions about this item
How much heat or noise does the 4-watt LED bar produce after running all day?
At only 4 watts the bar stays cool to the touch and has no fan, so it adds virtually no heat and makes no audible noise even after continuous use.
What USB power source do I already need to run the light bar?
Any standard 5 V USB port — computer, monitor hub, phone charger or power bank — will power the bar; no proprietary adapter is required.
Will the clamp fit the 1.2-inch bezel on my older flat-panel monitor?
Yes, the clamp adjusts from 0.4 to 1.2 inches (10–30 mm) and works with most flat monitors; curved screens are not supported.
