The Idea: Minimize Blue Light Before Bed

Numerous scientific studies have linked exposure to blue light in the hours leading up to bedtime with reduced sleep quality. The details are highly technical, but in general, lighting that is both dim and warm produces less blue light than bright and/or cool lighting. In addition, warm light can enhance the feeling of calm.

The Best Lighting for the Bedroom

The Philips A19 SceneSwitch Light Bulb transitions between three light settings simply by flicking a switch off then on. No dimmer is required - just your existing light switch.

The bulb has three modes:

  1. Dim, warm light (2,200 K, 80 lumens, 3 watts)
  2. 60 watt bulb setting (2,700 K, 800 lumens, 9.5 watts)
  3. Bright, cool light (5,000 K, 800 lumens, 8 watts)

Use setting 1 in the hours leading up to bed, as this provides the most comfortable light that can minimize sleep disruption.

Use setting 2 for tasks that require more illumination, such as reading or putting clothes away. Optionally, use setting 3 in the morning to promote alertness.

Be aware that setting 2 should be used sparingly in the evening, and setting 3 should only be used in the morning to mid-afternoon. 

Be sure to turn the light off when sleeping.
