Before the alarm sounds, the WL50 will gradually begin to brighten your room like a natural sunrise. Don’t get me wrong, the lamp looks great on my bedside table and doubles nicely as a portable speaker/light but that’s about all I’ll use it for.

After waking up well past my alarm time, I did learn the hard way that there is a minimum sound level for certain sounds that will cause the alarm to go off with no sound at all. If Bluetooth® has been disconnected, the acoustic signal on the wake-up light will sound again and the Bluetooth® symbol goes out. I used it at my desk in the office during my usual post-lunchtime lull - the point at which I customarily turn to strong coffee.To improve radio reception, plug the AUX cable into the AUX port or the micro-USB cable into the USB port on the back of the device. The best wake-up light alarm clocks serve that double purpose of improving mood, although dedicated SAD lamps tend to be brighter and more effective. Also known as wake up light alarms, bodyclock lights, natural light alarm clocks or SAD alarm clocks, these devices provide a novel form of light therapy.
