My light bulb color recommendations try to factor in these effects. When I bought orange UV safety glasses along with a UV flashlight to detect pet stains I read a lot of reviews of users using them at night to help them sleep and that worked for me too.īright lights also make it hard for you to go to sleep compared to dimmer lights. I've always had problems with sleeping and waking up on time and I've found that controlling the light color at night before bed has helped me a lot. Time appears to pass faster with blue light than it does with red light and blue colors suppress appetite. Light color even affects how we perceive time. Blue light at night can negatively affect our circadian rhythm, our internal clock that tells us when we should sleep and when we should wake up. For example, bright cool light during the day helps increase mood, alertness and productivity.Īt night, warmer light helps us sleep better and relax so in the morning we're less grumpy. There have been a number of studies on how the color of light affects us. My recommendations should make the harshness less noticeable to those that don't care for daylight bulbs. If you feel the daylight color is too blue for your tastes you can substitute a Cool White bulb instead of daylight but I suggest you try some daylight bulbs first. In between warm and daylight you'll find Cool White, Neutral and Bright White bulbs which range from 3,500 - 4100 K.įor the most part in these tips I've limited the choices between warm and daylight bulbs because those are the two colors available in the Philips bulbs I mentioned.
Natural daylight on clear day is about 5,000K while on an overcast day it's about 6,500K. LED bulbs are also available as Daylight bulbs with color temperature in the range of 5,000 - 6,500 K. They are sometimes labeled as Warm White or Soft White. Most incandescent bulbs emit a warm light in the range of 2,700 - 3,300 K and many LED lights try to mimic this color since we're so used to it. Lower color temperatures indicate a redder light while high temperatures indicate a bluer light. The use of Kelvin degrees has to do with the color iron glows when it's at a certain temperature. The color of light a bulb puts out is measured in degrees Kelvin (K). When they're dimmed they don't buzz or flicker either and I find the colors and light quality to be good.
