The 10 Best Therapy Lamps
Updated by · How we research
Ten light therapy lamps compared on screen size, settings and stated distance. Top pick: the Carex Day-Light Classic Plus, rated at a real sitting distance. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.
A "10,000 lux" label means little on its own, because brightness falls off fast as you move away. The figure that matters is how far from the screen it holds, and many small panels never say. These lamps are for people whose mood, energy or sleep timing slips in the dark months and who can spare a half hour most mornings.

Editor's Notes
November 1, 2026, by Ezvid Wiki Editors:
The Carex Day-Light Classic Plus now leads this list. Carex names the distance at which it reaches 10,000 lux, and its big head sits above eye level, which is how the Center for Environmental Therapeutics says a light box should be set up. Plenty of small panels quote the same lux figure with no distance at all, so we ranked stated distance and screen size ahead of extra settings.
This page now covers bright-light lamps for winter mood and sleep timing only. The Angel Kiss Wand, a skin-care light, and the Philips SmartSleep, a wake-up light, didn't fit that. The Verilux HappyLight VT31 and VT32 were replaced by the current Verilux HappyLight Lucent and Verilux HappyLight Luxe, while the Miroco MI-CL003, Philips GoLite and Alaska Northern Lights NorthStar turned up in no current listing. The Northern Light Technologies Boxelite and Circadian Optics Lumine stay.
The rankings lean on the distances makers publish, CET's screen-size and placement criteria, and the safety advice from the National Institute of Mental Health and the NHS.
Earlier notes
October 19, 2020:
It’s important to remember that therapy lamps are medical equipment and should only be used as directed by healthcare professionals. When used properly, these devices can improve skin disorders, treat Seasonal Affective Disorder, and boost energy levels.
If you’re looking to relieve problems like psoriasis or eczema, your doctor may direct you towards a UVB lamp. While these lights block UVA rays, they can still be harmful to the skin if overused, so caution is recommended. The Teenvix Hand-Held, which is no longer available, was replaced with the Angel Kiss Wand. Like the previously listed item, this model is a handheld device that uses UV light.
If you’ve been diagnosed with SAD, you’ll want to get a UV-free model with at least 10,000 lux, like the Northern Light Technology Boxelite. Though quite expensive, it emits light up to 14 inches and is one of the best on our list. With regards to other UV-free options, we replaced the Carex Day-Light Sky Bright with the newer and bigger Carex Classic Plus. While they’re both great models, the Carex Classic Plus has a larger 13.5 by 15.5 inch surface, is less bulky, and costs about the same.
If your circadian rhythm is off due to frequent travel, you may want a portable model to take with you on trips. At only 1.3 pounds, the Verilux HappyLight VT31 is travel-friendly and lightweight. Another good travel option is the compact Philips GoLite, which features a small square shape and can be tucked into a suitcase. Lastly, we replaced the outdated Travelite with the much newer Miroco MI-CL003. It is just as compact as the former, but offers a sleeker design and provides UV-free LED bulbs instead of florescents.
Some medical professionals suggest using your therapy lamp as soon as possible after waking up. The aforementioned Philips GoLite is small enough for your bedside table, which may encourage morning use. Likewise, the Philip’s Smartsleep, which is newly added to our list, functions as an alarm clock and can be programed to emit light as you’re waking up.

First off, medical devices like light therapy lamps should only be used as directed by a qualified medical professional. If you've been given such advice by a doctor, know that there are two types of light therapy you can undergo at home. Many sufferers of acute skin problems like psoriasis, eczema, and vitiligo find relief from UVB phototherapy, which provides the benefit of sunshine without the dangers of UVA rays. These require a particular level of caution because using them too much can still result in sunburn and other skin damage, despite the lack of UVA radiation. But as long as you use them properly, they're quite safe and can provide healing that you might not be able to get from creams or other chemical-based solutions. The Sperti is the top free-standing UVB phototherapy lamp, and the Teenvix is the most reliable hand-held option around.
For Seasonal Affective Disorder, you'll want a UV-free lamp, and you'll want a bright one. The Day-Light and both Veraluxes are great desktop models, though one Veralux is much brighter than the other. If you can afford it, the Boxelite is one of the best, and they're one of the few companies to advertise the distance at which 10,000 lux is produced. Alaska Northern Lights also publishes that number, and at 24 inches, their NorthStar just about the strongest we found. Smaller options like the Circadian Optics and Philips are decent for desktop use, but you'll have to be pretty close to them to get the full effect. If you don't have enough room to set one down, consider getting a floor-standing model.

Brightness Means Little Without A Distance
Carex rates the Day-Light Classic Plus at 12 inches, Northern Light Technologies rates the Boxelite at 14 inches, and Beurer says its TL30 gets there at about 4 inches.
Nearly every lamp here claims 10,000 lux, the level the National Institute of Mental Health describes for treating winter depression, about 20 times brighter than ordinary indoor light. But brightness drops quickly as you move back, so the number only means something with a distance attached. Carex rates the Day-Light Classic Plus at 12 inches, Northern Light Technologies rates the Boxelite at 14 inches, and Beurer says its TL30 gets there at about 4 inches. The Verilux, Circadian Optics, Theralite and Lastar lamps give no distance.
The nonprofit Center for Environmental Therapeutics sets out stricter criteria: 10,000 lux at a comfortable sitting distance, a screen larger than 200 square inches, and light that comes from above eye level. It warns that small boxes can read 10,000 lux on a narrow meter yet deliver less to your eyes, and that a small screen lets the dose fall every time you move your head. Only the two big lamps here, the Carex Day-Light Classic Plus and the Boxelite, come close to that screen size.
Small panels still have a place. They cost less, fit a crowded desk and travel well. Just plan to sit close, face the light and keep fairly still. If you can't stay in one spot, a wearable like the Luminette 3 puts the light right above your eyes, though at a much lower brightness.
When And How Long To Use One
Light therapy works on a schedule. The NIMH describes sitting in front of a 10,000 lux box for about 30 to 45 minutes a day, usually first thing in the morning, from fall into spring. Verilux suggests starting with about 10 minutes and building up, and notes that its lamps don't tan your skin or make vitamin D, since the light is UV-free.
You don't stare into the lamp. Set it off to the side or slightly above, at the maker's distance, and read, eat or work while the light reaches your eyes. A timer helps if you tend to lose track, and several lamps here have one.
Timing matters as much as time. The Center for Environmental Therapeutics offers free, anonymous self-assessments, including one that suggests when a night owl or an early riser should start morning light. Bright light late in the evening can push your sleep later, so most people keep sessions to the morning unless a clinician advises otherwise.
Are Light Therapy Lamps Safe?
For most people, yes. The NIMH says a proper light box filters out damaging ultraviolet light, which makes it a safe treatment for most. It adds that people with certain eye diseases, or who take medicines that raise sensitivity to sunlight, may need another treatment or should use light therapy under medical supervision.
Bipolar disorder calls for extra care. The Center for Environmental Therapeutics advises people with that diagnosis to stay on a preventive mood stabilizer, because bright light can trigger a switch into hypomania or mania. Talk with your doctor before starting.
Keep expectations realistic, too. The NHS doesn't usually offer light therapy because there isn't enough evidence to say how well it works, though it notes that many people find it helps, and it suggests seeing a GP first. These lamps are sold as wellness devices, not approved medical treatments. If low mood is severe or lasts, or you're in crisis, get help from a professional right away rather than relying on a lamp.
How we researched this
We compared 16 light therapy lamps and wearables, read the makers' specs and published distances for the 10 picks, followed the guidance from the National Institute of Mental Health, the NHS and the Center for Environmental Therapeutics, and searched the U.S. Consumer Product Safety Commission's recall database for every brand. We found no independent lab measurements of these lamps' brightness at a sitting distance, so the stated distances come from the makers.

Frequently asked questions
Are light therapy lamps safe?
For most people, yes, when the lamp filters out ultraviolet light. People with certain eye diseases, those taking medicines that raise sensitivity to sunlight, and anyone with bipolar disorder should check with a doctor first, according to the NIMH and the Center for Environmental Therapeutics.
How long should I use a light therapy lamp, and when?
The NIMH describes about 30 to 45 minutes a day at 10,000 lux, usually first thing in the morning, from fall to spring. Many makers suggest starting with shorter sessions and building up.
Do light therapy lamps work?
Light therapy has been a mainstay for winter-pattern seasonal affective disorder since the 1980s, per the NIMH. The NHS says the evidence is not strong enough for it to offer the treatment routinely, though many people find it helps.
How close should I sit to a 10,000 lux lamp?
As close as the maker specifies. Carex says 12 inches for the Day-Light Classic Plus, Northern Light Technologies says 14 inches for the Boxelite, and Beurer says about 4 inches for the TL30. Farther away, you get much less light.
Can a regular bright bulb do the same job?
Usually not. Ordinary room lighting is far dimmer than a therapy lamp, and the NIMH puts a 10,000 lux light box at about 20 times brighter than typical indoor light.
Will a therapy lamp give me a tan or vitamin D?
No. These lamps filter out ultraviolet light, which is what tans skin and triggers vitamin D, so they work through your eyes instead.
