In addition, an LED does not wear out like a traditional bulb, or as the most modern compact fluorescent: so you will virtually never need to change it (indeed it is not expected).
The cool white lighting is recommended for extended playback periods: it seems that it rests the eyes. Personally, I prefer warm white setting that I find more enjoyable.
This is indeed a special feature of this lamp than offering a choice of hot and cold, according to 4 nuances, with the ability to also vary the light intensity. (Touch controls respond well).
I like the USB port on the front of the lamp that can charge a phone or a reading light.
I like less the transformer on the plug: I think it would have been better to integrate it into the database.
