I was interested to find out what are some of the best light therapy devices to use that can help with seasonal affective disorder for me to review.

Using a bright light therapy lamp, or seasonal affective disorder device, can make a big difference for some people’s low mood feelings during dark Winter times.

So I went out researching online for what are the top rated & most recommended brands who make seasonal affective disorder light therapy products that are available to buy online.

The Best Seasonal Affective Disorder Light Devices in 2024

Here is the list of recommended SAD lights we reviewed for you to compare.

1. NatureBright SunTouch Plus Light & Ion Therapy Lamp

  • Suggested Use Time: 15 – 60 minutes
  • Type: tabletop light
  • Intensity: 10,000 LUX
  • Additional Features: negative ion therapy

NatureBright exclusively sells light therapy products, including sun screens and wake-up lamps. The SunTouch Plus emits prescription-strength light rays and has the optional capability to provide aroma therapy. NatureBright was established in 2001 and is committed to enhancing mood with natural light rather than drugs and traditional medicine. Their website features a comprehensive discovery page that explains the science behind light therapy and biorhythms. (ref)

Let’s compare some of the other features:

  • Includes negative ion therapy, which has rejuvenating properties

  • Includes a timer with four different settings: 15, 30, 45 and 60 minutes
  • Recommended by the New York State Psychiatry Institute and the Columbia Department of Psychiatry

2. ReTimer Light Therapy Glasses

  • Suggested Use Time: 30 – 60 minutes
  • Type: wearable glasses
  • Intensity: 500 LUX
  • Additional Features: none

ReTimer is a university-owned company that sells only one product: light therapy glasses. Although the intensity of emitted light is relatively low, ReTimer says that due to their proximity to the eyes, the glasses are just as effective as a lightbox that emits 10,000 LUX. The glasses can conveniently be worn while performing other tasks, but they are much larger than regular glasses. The ReTimer website features a jetlag calculator and a sleep calculator which tell you when you should wear the light therapy glasses to minimize jetlag and reset your sleep schedule, respectively. (ref)

Let’s compare some of the other features:

  • Since these are glasses, they are compact and fit for traveling

  • The ReTimer website has tons of useful information on the science behind light therapy and how to use the glasses

Frequently Asked Questions

I know you were looking for what are the best options, but here is some more detail as to why we need seasonal affective disorder lamps to help us wake up and beat the winter depression blues.

What is Light Therapy for SAD

Bright light therapy, or phototherapy, is the use of artificial light to treat certain conditions such as seasonal affective disorder (SAD). People with SAD often experience depression in the fall or winter months due to limited exposure to natural light. Light therapy has been proven to help relieve symptoms of SAD and is also used to treat jet lag, dementia, non-seasonal depression and sleep disorders. The intensity of light is critical and is measured in LUX. Normal room lighting is not bright enough to be used as light therapy. (ref)

Do SAD Lights Work

Yes, seasonal affective disorder lights have been found to help treat SAD. Although bright light therapy is not a cure for SAD, it can be effective in treating the symptoms. Researchers in more than 15 studies have found that even individuals who have a long history of SAD experience relief within one week of bright light exposure. (ref)

In one four-week study, 96 patients were either exposed to bright light therapy in the morning or the evening, or given a placebo. Those who received the morning light therapy showed the best results. The evening light therapy was shown to be more effective than placebo, but not as effective as the morning light therapy. Overall, the findings showed that bright light therapy, especially given in the morning hours, is effective for minimizing and even eliminating depression in a significant number of patients. (ref)

Types of SAD Lamps

In the past, bright light boxes were the only way to engage in light therapy. But in today’s tech world, many other options are popping up. Some of them are wearable, making them more convenient for people with on-the-go lifestyles. Here are a few devices for receiving bright light therapy treatment. (ref)

When to Use SAD Lamps

While SAD is the condition most commonly treated with bright light therapy, there are many situations in which light therapy can help people. People in the following situations may want to try light therapy. (ref)

Benefits of Using Light for SAD

Those with SAD can put their depression in remission with light therapy. Here are some of the benefits you might see after implementing this treatment. (ref)

Although you may see short-term benefits when using light therapy, you’ll probably still be affected by SAD when winter comes around the following year. Light therapy should typically be repeated each year during the season in which you are affected. (ref)

Is It Safe to Use Light Therapy Lamps

Light therapy lamps are very safe. There is no indication that they cause any long term damage to the body. Side effects of light therapy are rare and relatively mild; however, here are a few to be aware of.

These side effects can be minimized by limiting the amount of time you spend with bright light, as well as the intensity of light. Also, using a light box free of UV rays can reduce your chances of experiencing negative side effects. (ref)

Although light therapy has never been shown to cause any damage to the eye, people with eye conditions or diabetes may be more susceptible to side effects and should consult a doctor before commencing treatment.

People who have bipolar disorder should consult a doctor and use light therapy with caution. Light therapy may trigger episodes of hyperactivity or mania. (ref)
