Review on Enhanced TOMOL Super Bright COB LED Portable Travel Lamp: Foldable, Touch Control, 3 Adjustable Brightness Levels, Battery & USB Powered by Rob Bradford

Just right for nicely illuminating a far away keyboard and mouse combo when you don't need full bedroom lighting. It is used with 4 x 2600mAh AA batteries which add extra weight on the bottom to stay upright when fully extended. Mode 1 or 2 is enough to fully illuminate the keyboard and reduce eye strain when working in a dark bedroom. It also fits perfectly as a side table. To turn on the lamp, simply lightly touch your fingertips around the center switch O. Repeated touches will increase the light intensity and use all 3 light levels to meet your specific lighting needs. 4 batteries fail during operation. The light intensity falls off exponentially and cannot increase its intensity at the first or second light setting. To check which battery has failed, you need a battery tester. If you think it's a lamp fault, plug in the included charger and press the switch 3 times to check 3 levels of light intensity. If everything is fine, you're good to go. A portable bedroom lamp is highly recommended. use and travel.
