This unit is a gamechanger for me.

An excellent choice you will absolutely love. I feel this purchase was better than I expected. The build quality is superb. The button to turn it off and on is responsive and has a satisfying click. I have a usb plug next to my bed so it clips nicely nearby. It’s powerful. Enough so that you can bounce light off of your headboard from a good distance if you had to. That being said, it doesn’t blur the pages of a book if you shine light directly at it. The 4.5 inch cable is terrific, I plan on using this for night time meals like an overhead spotlight. I’m overjoyed to own this red light.

I really like the light, just wish the cord was longer.

thanks for the feedback! You can always get a USB-to-USB extender from Amazon or most electronics stores to get extra length.
