my illuminated keyboard stopped working a couple of months ago & until I bought this lightbar, I had to resort to turning on the light to be able to see the keys clearly on an older keyboard I have been using that does not have light up keys. USB Connection: The light bar connects via USB, allowing for easy power supply from a laptop or other USB-enabled devices. This makes it convenient for use with portable setups. e-Reading LED Task Lamp: Specifically designed for e-reading and tasks performed on screens, it reduces eye strain by providing even, glare-free illumination. Adjustable Color Temperature: Offers 3 color temperature settings (typically warm, neutral, and cool) to suit different lighting preferences and tasks, from reading to working. Brightness Levels: Features 10 levels of brightness adjustment, allowing you to customize the light intensity according to your needs and preferences. No Glare on Screen: The design minimizes glare on screens, ensuring that the light enhances visibility without disrupting your view or causing reflections.

Compact and Space-Efficient: The light bar’s design is ideal for small workspaces, keeping your desk uncluttered and organized. Ease of Use: Simple to install and use, often requiring no additional tools or complicated setups. Cons: Limited Power Source: Since it’s USB-powered, it relies on the connected device for power. This could be limiting if your USB ports are in use or if you’re using it with non-USB devices. Brightness for Larger Spaces: The light may be more suitable for personal workspaces rather than larger areas or for tasks requiring very high brightness. Compatibility Issues: Depending on the design, it might not fit all monitors or laptops perfectly, especially if they have irregular screen bezels.

This light is super bright when you need it bright, and dim when you dim it. Simple to use, plug in and done. It's perfect, the price is great, and I highly recommend it. I buy Amazon products weekly, and if I leave a review, it's either great or horrible. This one is great! Thank you guys for creating another great product. Cheers! Read more

Using these you don't have the room light Read more

I thought I'd get this to use on top of my monitor, since I don't actually use the laptop without it. But out wouldn't clip on. It is however very bright, with 3 light settings and it's dimmable, and you do all this from a control on the lead. Great.... for laptops. Read more

Inefficient to light up my room just to see the keyboards. Neither of my older but good working laptops have back-lit keys. I have been struggling to see and use them in early mornings or evenings. No more! These clamp on led lights are great. I like the blueish setting at a low level. The laptop on the left is on and the right is off. Huge difference. I am very pleased with the functionality of these computer lights. Completely adjustable and they stay on as long as the USB is powered. Read more
