Best way to use TUO circadian bulbs
For best results, the TUO bulbs should be the dominate source of light in a room or space. Other light can actually contribute to cancelling the effects of the light or significantly minimizing the effect.
Mornings are the most important to setting your daily rhythm, so this is especially important during your circadian scheduled time for WAKE mode. Please make sure that the TUO light is the dominant source of light during this time.
TUO works on light activating the circadian pathway in your retina, so do not use lamp shades or light covers that block a lot of light. We recommend a light fixture with an exposed bulb for ideal results. Even clear or white covers sometimes are doped with light blocking chemicals and can reduce effectiveness.
TUO light works at even low light intensities, as low as 20-30lux (about a single candle) - but it is best to have the TUO light bright enough to have an effect for WAKE and ACTIVE modes. Normal lighting levels are of 150-300lux is fine.
In the evening, CALM mode is calibrated to NOT effect your circadian system at any brightness. If you want to take additional precautions, reduce the brightness of the TUO light, and especially other lights and electronics. For regular lights, we recommend below 150lux, which should seem only slightly "dim" to the room.
