If you are experiencing difficulty falling asleep or you keep waking up in the middle of the night because of lack of sleep, it’s time you got a solution to this problem. Good sleep is generally vital for your health and your body’s overall well-being. So, a simple change with the best light bulbs for sleep can make a big difference.

It is easy for people to underestimate the power of light in improving sleep quality. The truth is that various scientific studies have been conducted on the effect of light on sleep and results show that light can actually impact your sleep cycles or interfere with your internal biological clock.

According to a sleep physician Dr. Pranshu Adavadkar, it is good to keep your room dark if you want to experience quality sleep. However, if you must have the lights on, you should choose warm colors like amber and red lights because they have a calm and relaxing effect that helps you sleep faster and better. You should, however, keep off green and blue lights because they affect your normal sleeping cycle by playing tricks on your mind.

In this review, we will take you through the best light bulbs that won’t interfere with sleep, how they work, side effects, and much more.

What are Sleep Light Bulbs?

According to experts, the warm light we get from a setting sun signals the body when it is sleeping time. However, artificial lighting we use in our homes after sunset usually interferes with the circadian rhythm, hence leading to sleeping disorders like insomnia.

The best light bulbs that block blue light for sleep are dimmer lights designed for use a few hours before bed. They are suitable for bedrooms and bedside lamps. The bulbs emit zero flicker with a low EMF, which makes them ideal lights for sleep. Sleep light bulbs like amber and red light bulbs are vital components when it comes to maintaining the circadian rhythm and lighting up your house at night.

According to a study in Neural Regeneration Research, red light exposure at night has been found to improve the quality of sleep and the body’s overall health and wellbeing.

Another study in PLOS Biology Journal notes that red light therapy can help reset the internal clock of the body which has been disrupted after a visit to regions with different time zones. Such people experience what experts call jet lag, a condition characterized by insomnia, fatigue, and inability to concentrate.

How Do Sleep Light Bulbs Work to Promote Better Sleep?

Sunrise and sunset rhythms serve as the body’s sleep and wake signals. When it is daylight, the body is aware that it is time to be alert and awake and when is nighttime, the body switches to the state of calmness, relaxation, and sleepiness.

The best-led light bulbs for sleep work by influencing the 24-hour natural biological clock of the body that controls sleep timing.
Amber and red-light bulbs emit light that helps increase the production of melatonin levels in the body, enabling you to fall asleep easily and get quality sleep. Our iRED USA Review also notes that red light improves sleep cycles.

According to Leela Magavi M.D., a psychiatrist and regional medical director at MindPath Health says that light therapy treatment can help normalize a person’s circadian rhythms through its ability to stimulate retinal cells that consequently affect part of the brain responsible for regulating a good number of body functions.

What are the Best Color Lights for Sleep?

Amber Light:

Amber is considered one of the best color lights for sleep because of its calming effect that enhances better sleep. It enhances mood and makes you experience calmness as it works to promote melatonin synthesis for better sleep. Amber light does not affect melatonin secretion, a hormone that helps you fall asleep. Lighting your house with amber light will also help protect your eyes from the damaging effects of blue and green light which are considered harmful.

Red Light:

Various studies have proven that wavelengths from red light can help you sleep better. This is because red light has a low color temperature that mimics what you experience during sunrise and sunset which is often lower.

Conventional light bulbs on the contrary are said to emanate a melatonin-inhibiting light. Red-light bulbs on the other hand have been known not to interfere with the internal clock and, therefore, can’t prevent you from having quality sleep. It is responsible for increasing melatonin synthesis in the body, a hormone responsible for promoting sleep.


Research has revealed that yellow-colored light can be a good option for use at night as it has little impact on circadian rhythm. Exposure to yellow light, therefore, can help increase the production of melatonin in the body compared to cooler colors like blue and green light.

Why Are Ordinary Light Bulbs Problematic for Sleep?

Ordinary light bulbs including fluorescents and LEDs are considered problematic for sleep because they produce extreme artificial blue light. That is, they emanate a type of blue light which according to sleep experts, the light always inhibits melatonin, a sleep hormone, thereby causing delay in falling asleep or difficulty in falling asleep.

Colors to Avoid When Selecting Sleep Light Bulbs

Blue Light:

Blue light has been found to affect circadian rhythm by suppressing melatonin production and also making the body remain alert.

Regular exposure to blue light especially at night can disrupt circadian rhythm by tricking the brain that it is still daytime, hence reducing the quality of sleep.

Well, as we noted in our content titled The Ultimate Red Light Therapy Guide, blue light is not that bad as studies have shown that it can help boost alertness making it great for use during the daytime during working hours. However, it may be counterproductive during nighttime when the body needs to rest.

Green Light:

Green light just as blue light also reduces drowsiness. According to a study published in the Sleep Journal, green light reduces melatonin synthesis, a crucial sleep hormone in the body. This in turn counteracts sleepiness making it difficult for someone to fall asleep.

Key Factors to Consider When Selecting Sleep Light Bulbs

What Specific Benefits Do Sleep Light Bulbs Offer?

Natural Production of Melatonin:

One of the identified benefits of a sleep light bulb is to promote melatonin synthesis in the body. Melatonin is a hormone known to play a crucial role when it comes to promoting quality sleep.

A publication in the Journal of Athletic Training by Jiexiu Shao et al notes that exposure to red light can help improve sleep and promote melatonin levels hence preventing sleep disorders.

Muscle Relaxation:

Things like a long day of work, training, or exercising can lead to muscle soreness, pain, and strain. One of the best-proven ways of relaxing muscles is light therapy. Red light exposure has been found to enhance muscle relaxation.

A research study published by Ferraresl and Clerbe Ph.D. et al in the American Journal of Physical Medicine & Rehabilitation shows that phototherapy can help reduce muscle damage after training enabling them to relax. It also enhances muscle recovery.

Calm Feeling:

There is clinical evidence that light therapy treatment can provide a calming effect by reducing stress, anxiety, or depression-related symptoms.

According to a publication in the Healthcare Journal by Ian M. Kronish et al, light therapy can help improve depression symptoms hence helping you to keep calm and relax.

Prevent Sleep Inertia:

Sleep inertia is a condition that affects the normal sleep cycle. Exposure to light has been shown to reduce this sleep disorder.
