There are literally hundreds of brands of this usb gooseneck-type light. This has an on/off hi/low switch, is inexpensive and the light covers my entire keyboard whether tablet or laptop. And even better...low setting on the light is wonderful for late night-bleary-eyed web surfing. High setting is just right for early evening activities. Amazingly, neither setting is too bright, rather its a well diffused and pure white light...just right. I also plugged it into a usb wall charger for a tremendous travel night /reading light. I love this little thing...and to think I ordered it solely based upon the Mighty-Bright name. The ONLY one I had ever heard of previously. Its a great light and I intend to order more!
