The best light therapy lamps for Seasonal Affective Disorder (SAD) are more commonplace now. As we get better at talking about mental health, we can open up our conversations to recommending the things that help. This includes light therapy lamps, which are specialist sun lamps designed to ease the symptoms of SAD. 

SAD symptoms (low mood, depression, fatigue, poor concentration levels and energy) worsen during winter, but can arrive as early as fall. This is why doctors suggest using a SAD lamp for 30 minutes each morning from the first day of fall. The very best light therapy lamps are designed to boost levels of serotonin (the ‘happy chemical’) in your brain by recreating the effects of natural sunlight. 

Daylight plays a role in how well you sleep, so no wonder sun lamps can help regulate your circadian rhythm (body clock) if you can’t get out for a daily stroll when the sun is high. Sleep, of course, is a natural mood boosters, so make sure you’re sleeping on the best mattress and pillows for your sleep style to give yourself the best chance of drifting off. That said, with depression and SAD, waking up can often be the challenge. If you have trouble waking, take a look at our guide to the best sunrise alarm clocks for a more cheerful wake-up call.

The best light therapy lamps all have a 10,000 lux output, which is the ambient measurement of daylight. To use one, ensure the sun lamp is sat slightly to the side of you. Avoid staring directly. Don’t worry, you can keep your eyeglasses on during a SAD lamp session. If you’re taking medication or have an underlying health condition, check with your doctor before buying a light therapy lamp to ensure they’re safe for you to use.

Best light therapy lamps FAQ

Do light therapy lamps really work?

Sun lamps mimic outdoor light, which researchers believe triggers a chemical change in the brain that helps with the symptoms of low light levels, such as fatigue, low mood and lack of focus.

Many reliable sources, such as the National Sleep Foundation are supporters of light therapy lamps, but while these SAD lamps are effective for most people, they won’t work for everybody or they might only work to a lesser degree. However, when tested against a placebo, studies showed the sunlamps genuinely do make a difference, whether it’s a little or a lot. 

Ultimately though, proof can be found by testing out a lamp for yourself. There are plenty of cheaper options that you can start with to provide you with your 10,000 lux every morning. And, should you find the extra light beneficial, you can upgrade to a lamp with more features or buy an extra one to take to the office.


Can a sun lamp ease Seasonal Affective Disorder?

If you have SAD or any other type of mood disorder, the first port of call should be your doctor, but light therapy lamps can help ease symptoms to a degree. If your moods are suffering because of S.A.D., other factors such as exercise, diet and sleep need to be looked at too.

While researchers at Harvard Medical School do not cite light therapy lamps as being a cure-all for S.A.D., they do suggest that such lamps are effective at easing symptoms. Sun lamps aren't suitable for everyone though, especially if you have eye health issues or certain mental health conditions. 

The American Psychiatric Association also claims that light therapy can help with S.A.D. and has seen positive results in patients within as little as one to two weeks. 


How much do the best light therapy lamps cost?

Smaller sun therapy lamps cost between $10 and $75. However, as I found out during testing, just because a sun lamp is advertised as a 10,000 lux lamp doesn't mean it's 10,000 lux when sitting at a comfortable distance. 

If you find light therapy is effective for you, it's worth it to buy a larger lamp, as these provide better coverage and a brighter light at further distances. Large light therapy lamps start at $150 and can reach upward of $500. The only additional cost to consider is light bulb replacements, which can vary between $6 and $52 per bulb, depending on the lamp.

How long should you use a light therapy lamp for?

Every individual has different needs. You may need 45 minutes under the SAD lamp each day instead of 20 minutes. You can also get the same benefits from a lower brightness, but this takes longer. So if the light reaching your eyes is 5,000 lux, you may need to double the amount of time you spend next to the light compared to a 10,000 lux sun lamp.

Since the lamps are meant to simulate the brightness of sunlight, we tested each one using the Extech LT45 light meter. The brightness of a light therapy lamp diminishes as you move further away from it. 

An inch, for instance, can mean the difference of 1,000 lux. For example, at 16 inches, the brightest lamp in this test measured just 3,900 lux, but the same lamp measured 10,000 lux at 12 inches. You could move your head just 4 inches and lose nearly 6,000 lux.


Why else do people need lamps that simulate sunlight? 

Apart from SAD, there are many other reasons why a sun lamp is a great choice, such as if you live in a basement flat for instance, and do not get the natural daylight you need. Light therapy lamps can also help with the effects of seasonal time-shifts and jetlag, as well as anxiety and sleep disorders. Light therapy is also said to possibly help with dementia, although more evidence is needed.

Meanwhile, there are plenty of people who simply enjoy the level of light offered by light therapy lamps, and like to have the atmosphere while they work or relax, as a quick pick-me-up or mood-booster. However, if you have bipolar disorder or any eye conditions, it’s worth checking with your health practitioner first to see if light therapy is suitable, as it may trigger adverse reactions.


Is the coverage of a light therapy lamp important?

Larger light therapy lamps are not necessarily better than smaller ones, but you should choose a lamp with enough coverage that you can sit by it for 30 minutes without having to stay still. This is a problem with small light therapy lamps since their coverage is not big enough. As mentioned, you could move your head a few inches and significantly reduce the benefits of the light therapy lamp.  

Getting the right amount of light and the proper amount of coverage likely means adjusting the angle of the SAD lamp. Experts recommend that sun lamps should be angled downwards at 30 degrees, but it doesn't really matter what angle the light is aimed, you just need to be able to comfortably read or work on a computer while receiving the light without having to look directly into the lamp.

How does light therapy work?

While there is still some debate over the physiological causes of Seasonal Affective Disorder, the scientific consensus is a lack of natural sunlight. The sun is thought of as a natural antidepressant because it helps regulate our circadian rhythm. It's also our primary source of vitamin D, which boosts our brain's serotonin production. 

Light therapy lamps are therefore designed to alleviate the symptoms of a disrupted circadian rhythm, rather than the conversion of UVB radiation to vitamin D. In other words, light therapy lamps aren’t going to give you a tan. 

If you suspect you have a vitamin D deficiency, chat to your doctor about foods and supplements that may help.


When should you use a light therapy lamp?

There are specific times of the year and day when it’s especially beneficial to use a sun lamp. As mentioned above, doctors recommend light therapy lamps for people who experience Seasonal Affective Disorder, or who spend a lot of time indoors.

Winter is the most popular time of year to use the best light therapy lamps. That's because the days are shorter, so you're less exposed to mood-boosting sunlight. Getting extra light from a sun lamp can help bolster your mood and regulate your circadian rhythm (good news for your sleep). That’s because sunlight affects the hypothalamus, the part of the brain that dictates your circadian rhythm and moods. 

The hypothalamus is in charge of releasing melatonin and serotonin, and it depends on light to regulate and distribute these hormones. When you don’t have enough sunlight, this process gets disrupted, which may lead to depression and insomnia.

For the same reason, the best light therapy lamps are good for people who live far north or south of the equator, especially during the winter months.


What are the risks of using a light therapy lamp?

According to the Center for Environmental Therapeutics, light therapy is not recommended for people with the following pre-existing conditions because of the way it affects the skin and eyes:

  • Retinal dystrophy
  • Age-related macular degeneration
  • Porphyria
  • Lupus erythematodes
  • Chronic actinic dermatitis
  • Solar urticaria

You should also avoid using a light therapy lamp if you're taking medications that are known to photosensitize skin:

  • Psychiatric neuroleptic drugs
  • Psoralen drugs
  • Antiarrhythmic drugs
  • Antimalarial and antirheumatic drugs
  • Porphyrin drugs
  • St. John's Wort

In addition, PsychEducation warns about using light therapy if you have bipolar disorder as it could induce manic episodes. If you have bipolar disorder, talk with your doctor to determine if sunlight therapy is suitable for you.
