WOERFU Desk Lamp with Clamp Dimmable LED Bedsid Reading Lamp 10-Level Dimmer with 3 Lighting Modes Small LED Clip Table Lamp

This is a good stylish silver metal USB powered desk lamp. The clamp is quite strong and has a reasonable opening width. The adjustable goose neck holds its position well. The LED head has three different color modes that cycle between cool white LEDs, warm white LEDs, or combined cool white and warm white LEDs. There are quite a few different brightness modes that pull anywhere from about 75mA (0.375W) of current/power up to about 600mA (3W) of current/power. It would have been nice if this had a built-in rechargeable battery, but one can always power this off an external power bank if that functionality is desired.

I needed a desk lamp with a clip that would clip on to my metal desk that has a rounded frame. The jaw opening had to be at least 1 inch with the tension strong enough to hold the lamp steady. This clip worked great! I also needed a lamp that wouldn't be so long that it got in the way when I'm working. Best feature, I can use the USB or outlet for power and the switch located on the cord made turning on/off convenient. I didn't like having a battery that needed care. Would purchase again!Sept. 2018 Update: Stopped working after 11 months.

Just got these. Ordered two. Got them for use by the computers for my wife and I. The clip will open quite a bit and fits great on the edge of our desks. I would guess the width is about 1 1/2. If you use the clip to stand on you can't bend the light to far over the clip or it will fall. It works as a stand though but I like the clip. It dims which is great for early morning work and seeing your keyboard. Different colors so you can pick the color best suited to your eyes. These are outstanding

This is the perfect light for my sewing machine! It's light enough to clip onto my clear extension table to flood the sewing bed with three options lighting types in varying degrees of brightness. It's a slim/sleek light bar; the width is perfect. I even like the white color.A few things it doesn't do: the cord does not get in my way. It is long enough to go backward over the table and reach my surge protector on the floor. It does not get hot, and it does not get in the way of threading or sewing machine adjustments.Would give it more stars if I could!

This lamp does what we needed. It's a great reading light for next to the bed. The warm color setting is good for not tricking your eyes it's not time to sleep. The light it produced is focused compared to some other designs that create more of a spread. That, combined with the fact it dims nicely to a soft, low output means it does not disturb my wife as she sleeps next to me. I'm not sure why it needs an usb adapter to plug in. Maybe that's to make it compatible with different power plug designs. You can easily get the one you need, so that's not a big deal. My only complaint is it's fairly small. The cord is short. It works where we want it, but it would need an extension cord almost everywhere else. The goose neck is short too. As others have reported it's about 14 inches long. It could work as a desk light, but not for a big desk. And even for a small desk it's probably not ideal.

Love it. As an illustrator, this light is just what I needed. The metal clip on the base has a great 'bite' and is easy to clamp onto my desk's edge. The neck is flexible and holds the shape you bend it into. The light itself is 9" long, plenty large enough to illuminate my work but without getting so large as to get in the way. I can power the light through my computer via the USB port, or I have an optional AC adaptor which I can plug into a wall if needed elsewhere. The settings adjuster feels sturdy, the buttons have a strong clickback to them. The light can be switched from 'warm', to 'cool' light, as well as a third setting somewhere in between. There are also 10 settings of brightness adjustment, so I can dim it low for a nice evening lamp, or crank it up and blast away any shadows on my illustrations as I work. Great product!

I love this light!! It works really well as a light over my work area at my computer. It's easy to install, just clip it on the flat screen. Then I have a USB hub right there and it's all set. Couldn't be easier! Also you can choose warm or cool light. Plus it has a dimmer. You couldn't ask for more. It's perfect!!! Plus I can easily move to another location for reading in bed or working on crafts. Great deal!!!

I bought this lamp for my husband to use when drawing at his desk. It's been a great purchase. He uses it pretty much every day and has been doing so for over a year now. It's still just as good as it was upon first use. The clamp feature was essential to avoid taking up precious real estate on the desktop. He has it clipped onto his computer monitor. The clamp is very sturdy, it doesn't come loose or move when you're adjusting the neck of the lamp. All around highly-recommended.
