The lamp has 4 functions: Reading, Study, Relax and Sleep - all fit really perfect for each description.
Study Mode is perfect for learning or work to be concentrated. (6000 Kelvin light intensity)
Reading Mode is ideal for reading, pleasing to the eye. (5000 K)
Relax Mode I use as an indirect light source, very nice and warm light. (4000 K)
Sleep Mode I sometimes use to fall asleep in combination with the practical 60-minute timer, so you do not have to get up extra again - the lamp is easy after 60 minutes of alone out. (3000 K)
When changing these modes also changes the color while the Study Mode has a cool white, one has the Relax Mode a very cozy warm white. Big plus!
One can, of course, the intensity of self-regulated by the + and - buttons.
The lamp according to the manufacturer should keep 40,000 hours and save, especially when compared to a normal light bulb lot of money, about 90% less consumption!
The lamp is the "base" a stable state. One can you point where you want, a very flexible table lamp.
Is also great that by the USB port (1A output) can be charged directly to the lamp my smartphone - at your desk, so one does not have to walk forever to outlet. For me, very convenient!
