  4. GE - SleepLite Dusk-to-Dawn LED Amber Night Light - Angle_Zoom

    Product Description

    Enjoy sound sleep and wake up well rested with the GE LED SleepLite. Using special LED technology, the soft, warm LEDs distribute a tranquil candlelight glow in your room at night, providing the illumination you need to move about, but without the blue wavelengths found in most white lights that disturb your body’s natural sleep cycle. In the digital age, time spent in front of our screens — including tablets, phones, computers and televisions — is an integral part of our work and recreational life. Since the blue light emissions found in our devices tends to suppress the body’s production of melatonin (or the “sleep hormone”), exposure to excessive LED blue light at night can disrupt our natural internal clocks. The warmer hue of the SleepLite yields virtually no blue light, supporting healthy melatonin levels that tell our bodies it’s time for rest. By promoting a natural sleep cycle, the SleepLite works to improve your overall sleep quality. It’s time to use light to your advantage with the GE LED SleepLite.
