I usually wake up around 3 in the morning and have a hard time going back to sleep. The only way to get sleepy is to read. So, for years I have had to either go to another room to read or try to stealthily turn on a light next to the bed and hope that it doesn't wake my wife. Now, thanks to the Glocusent neck lamp, the problem has been solved! One of the device's two LEDs provides enough light, and switching them on and off produces no noise.
