Discover how to take advantage of your LED lighting to improve sleep and feel more energized in your day-to-day life.
Red lights have a longer wavelength and a lower frequency than blue light. As a result of this, red light looks dimmer and warmer. On the contrary, blue light appears cooler and brighter because of its high frequency.
Various wavelengths and frequencies of light have different effects on the entire body. Brighter, cooler lights may negatively affect melatonin production, the sleep hormone that is naturally produced by the pineal gland. Moreover, cooler light may disrupt the body's sleep-wake cycle, also known as the circadian rhythm.
If you think about it, until electricity was invented (thank you, Benjamin Franklin), people would be awake when the sun was up and resting as soon as the sun was down. Their bodies functioned on a clear schedule. With the advent of power, technology, and near constant light stimulation, our own bodies can sometimes get confused. (Avoid taking a look at your cell phone and TV before bed!)
The colour temperature of an LED light can be measured on the Kelvin (K) scale. Dimmer, warmer lights are somewhat lower in kelvin. Whiter, brighter, and bluer lights are higher in kelvin. Select LED bulbs are available in a range of 3,000 to 5,000 kelvin -- becoming cooler and brighter as the value increases. View the yellow circle at the LED bulb list shown below to know where to look for color temperature.
Now let's get back into red vs. blue. Because its cooler in color, blue light is greater in kelvin. This is a great thing for certain situations, such as daytime lighting or task lighting. Think: an office space in which you want high levels of awareness and productivity.
On the other hand, red light appears warmer and darker. It's lower in kelvin and more beneficial for regions of relaxation and rest. Consider: the bedroom where you wind down before bedtime.
Have a look at our variety of LED lights and bulbs, and take note of which choices can be found in various color temperatures. We offer an assortment of fixtures, from recessed lights to flat panels to wall sconces and everything in between. This allows you to strategize your home lighting, optimize the function of every room, and choose an elegant fixture that fits each space!
Want cozy bedroom light that will not irritate your sleep cycle? Move with a softer, warmer light that is reduced in kelvin, and you're going to be sleeping like a baby in no time.

I know, I know - now you're super interested in the science behind light frequencies and wavelengths! Takes me back to undergrad physics classes. Dive in the history and physics of light (in way more detail) here. Do not hesitate to let the nerd out.
