Question: Why does the lamp turn off on its own sometimes while I am using it? It does it quite often and is quite frustrating.
Document: I am quite happy with the quality of this LED desk lamp.It is nice to be able to vary the intensity of the light.Full bright is plenty. In between there and off is workable.The flexible neck allows me to remove glare from monitor.
I received the lamp on time, opened the box; saw a fairly nice lamp given the price. Already read some questions and comments, I knew I might need to wait after plugging for few minutes (3-5)to turn on, but it didn't. I cannot give it more because It is supposed to work. Another issue is that the waiting time differed between one lamp to another (according to comments).
I love this lamp - the lower levels are great for softly lighting the desk area while I'm focusing on the computer screen. A fingertip touch is all that's needed to increase the lighting when I turn to work on paperwork. The bright light is great for even small print with my &#34;getting older&#34; eyes. I cannot believe this is a 6 watt lamp. Amazing.
I recommend this lamp to those who are short on space on their desk but need more light to work properly,  It's a fine lamp, small, flexible, modern looking (white plastic and black goose-neck). It does indeed dim to quite low light, I just wish it went a step or two brighter than it does. The light is also a bit soft, so you don't get that harsh glare. This is fine for the price.
It is the perfect desk light. It's flexible and I love how you turn it off and on. Just slide your finger.
i bought about a month, and i thin this is good, but today when i turn on it, it is broken, i cannot open the lamp, when i put my finger on it, it just light a moment, and then it shut down automatic, and this situation does not change. and i also do not know how to solve this question
Wonderful desk lamp for computer desktop area. I bought this to get just enough light to be able to see the key board, to be energy conservative, and to not get really hot and add to room temp during the hot summer months. I live in NC and am retired. My other lamp is Ott and used the halogen 13W 60W which was bright enough, but it gets hot and I could even feel it. Higher bills using my heat pump AC too.
Best purchase, absolutely love it! It sits right next to my bed on a night stand and is a breeze to turn on or off. The illumination is just perfect for nighttime, when all other lights have been turned off, and perfect for late night reading, or a sufficient source of light to watch TV and putter around the bedroom. Compact size, clean lines, great performance.
This is my first LED desk lamp purchase that I can actually see more than a foot away while in use.
I really like this lamp, it provides a nice bright light and is easy to operate. Don't know why I need four more wordw?
