Best Light Bulbs for Sleep

Exposure to light can have both negative and positive impacts on your sleep health. Light bulbs designed for sleep typically limit blue light exposure and encourage restful sleep through features like warm colors and dimming.

When choosing a light bulb for sleep, consider your nighttime routine, where you might place the bulb, and whether a nightlight is needed for a bathroom or child’s room.

Some light bulbs use colored light to mimic the setting sun, while others have varied brightness levels for daytime and nighttime. There are also bulbs that are dimmable and others that can be used with apps and voice assistants.

We’ll provide a detailed look at the best light bulbs for sleep, and discuss the types of light to avoid for improved sleep hygiene.

How Is a Light Bulb Designed for Sleep?

Exposure to light can impact our ability to fall asleep and stay asleep. Bulbs that are designed to promote sleep health typically include features that limit harmful light exposure and mimic natural light.

Some sleep bulbs are intended to produce bright light during the day and dimmer, amber light at night. Some smart bulbs work in tandem with apps, smart hubs, and voice assistants. These bulbs can be set on timers to dim and brighten during certain parts of the day.

What Type of Light Bulb Is Best for Sleep?

Bright lights keep us alert and awake in the daytime. At night, we need less vivid lighting to help ease us into sleep.

Bulb Type Description
Incandescent Bulbs These are the traditional white light bulbs that are often found in homes. While they are not the most ideal bulbs for sleep, they do produce warm, dispersed light that can be conducive to sleeping.
Halogen Bulbs Halogen bulbs are less common in homes and are more often found in outdoor spaces. They give off strong, white light that closely mimics daylight. To promote sleep, they should not be used in the evening.
CFBs Compact fluorescent light bulbs are the energy-efficient bulbs that were more popular prior to the widespread adoption of LEDs. They tend to produce a lot of blue light, which can disrupt sleep patterns.
LEDs Light-emitting diode bulbs have become increasingly popular for household use in recent years. Many LEDs that aren’t specifically designed for sleep health give off a considerable amount of blue light and are not recommended for use in a bedroom.
Red Bulbs Red may not be a common light bulb color, but these bulbs are excellent at promoting sleep quality. Unlike blue light, the red wavelength doesn’t suppress melatonin production, which can lead to more restful sleep.

What Color Temperature of Light Works Best for Sleep?

Natural light and light produced by bulbs exist on a color temperature spectrum. Color temperature defines a light’s brightness and tone. For example, at one end of the color temperature spectrum is candlelight, which is dim and warm. On the opposite end is sunlight, which is bright and white.

Light bulbs with higher color temperatures tend to keep us alert and awake, while lights with lower color temperatures promote sleep.

How Is the Color of Light Influenced by Color Temperature?

Color temperature is measured on the Kelvin scale. A light with a lower number is on the dimmer, warmer end of the scale. A light that is bright and white has a higher number.

A standard incandescent light bulb generally has a color temperature of 2000K to 3000K. Amber light bulbs designed to enhance sleep usually have a color temperature around 1600K to 1800K. Daylight on a sunny to partly cloudy day typically ranges from 5000K to 6500K. Blue light tends to have a color temperature on the higher end of the scale.

How Does Blue Light Affect Your Sleep Patterns?

Blue light occurs naturally in sunlight but is also present in household light bulbs and electronics, like TVs or cell phones. During the day, blue light keeps people alert and focused. At night, however, being exposed to too much blue light can affect melatonin production and circadian rhythm.

Melatonin is a hormone that the body naturally produces to stimulate sleep. Circadian rhythm is the natural 24-hour sleep cycle that tells the body to be awake in the day and to sleep at night. Exposure to blue light in the evening suppresses melatonin production, which can throw off the body’s natural sleep cycle and result in lowered sleep quality.

Light sources that are designed to mimic natural light and reduce blue light exposure at night can help the body produce melatonin and get ready for sleep. Limiting the use of electronics before bed and using light bulbs designed for blue light reduction can have a positive impact on both sleep hygiene and sleep quality.
