I was looking to change my desk lamp because it was too bulky and the halogen bulb was generating way too much heat. While browsing, I found that Anker was selling an LED desk lamp. Having previously bough a fantastic USB charger form them, I was intrigued and bought one. After a couple of weeks of use, I must say that I would not want to get back to my old halogen lamp and all its heat. You can set the light in 4 modes and 5 dimming levels. In the evening, I set it to a warmer and lower level so it won't keep me awake forever.
I love this lamp, the only drawback is that it's all plastic so don't expect to be as sturdy as an all metal lamp.
