Because some are complaining about a lack of mobility of the lamp, I once appended a small photo montage demonstrating the lamp at minimum and maximum reach.
In the smallest projection lamp is (about) 40 cm high, the end of the lamp is only 17cm away from the foot. At maximum projection lamp is only 33 cm high, but enough for 42 cm wide.
For me, the lamp is not directly on the desk but slightly raised, so my throat completely sufficient that but everyone must decide for themselves.
The often criticized button Tuen flawlessly their service with me.
In standby I have measured at 0.6 watts me. So if you let a whole year around the clock in standby the lamp, formed at 24 cents / kWh accordingly about 1.20 electricity costs.
Positives:
-By Elongated arrangement of the LED books are evenly illuminated, without disturbing shadows in the rebate
-By USB connector you do not have awkward crawl under the table to charge a device, but has a charging port right under your nose.
-Good Mixture of bright light in the Read & Study modes and cozy light in the Sleep and Relax modes.
-No Flicker during dimming of the LEDs.
Needs improvement:
-You Must turn the lamp first, before you can select the mode. Why not just turn the lamp on the modes switch?
Conclusion:
As long as the projection for your application sufficient a strong buy recommendation!
PS: As an additional possible application "abusing" I have the lamp still as wide light source for poor shadow to photograph objects.
