r/productivity on Reddit: Best SAD light lamps for better productivity
December 1, 2024 -

Winter hitting hard here in the Midwest. Productivity getting worse. Maxed out on my vitamin Ds and other multivitamina.

I need SAD lamp recommendations.The buzzwords I've read so far is 10000 lux. Is there something better out there for productivity? How long before you start working do you use it? How frequently?

Please drop me your favorite brands AND Amazon links if possible (pretty please). I'm okay investing a little bit more and going up to or more $50.

December 18, 2023 -

I have a home office in my basement that has built in lights in the ceiling. I am trying to find which light bulbs are closest to sunlight since I am spending a lot of time in the room and it gets very little sunlight. Right now I have fluorescent lights in the room, and am wondering if there is a better option. Thanks in advance for the help!

r/HubermanLab on Reddit: I just finished testing over 35 SAD light therapy lamps! Here’s the data:
December 23, 2023 -

I still have a number of lamps to test, but since we’ve hit the gloomy season I thought I’d share this with ya’ll in case you’re in the market for one!

For those of you who want to check it out: Here’s the database!

(I now also have a list of the best SAD lamps according to my testing for those interested

It’s hard to know who’s telling the truth about their products, this includes SAD lamps. So just like in my previous post on blue-blocking glasses, I set out to objectively test these lamps with a lab-grade spectrometer!

Testing is done by placing each lamp 1 foot from the spectrometer. Readings are then taken every minute for an hour.

This allows me to see what the emission spectrum is like over time since LEDs often shift (sometimes quite dramatically) as they warm up...

The following metrics were tested:

Lux

This is of course the most popular measurement for a SAD lamp. Lux is an area-based numerical value based on the spectrum of light a human is most visually sensitive to.

We often see "10,000 lux" touted as the holy grail minimum, and so many lamps claim to hit this as a sort of buzzword marketing gimmick. But...

  1. There's nothing special about hitting a minimum of 10,000 lux, so I wouldn't be overly concerned with that number specifically.

  2. There's a better metric for circadian effectiveness anyway...

Circadian Light

Using the spectral data collected during testing, we can calculate the circadian light from each light source.

Circadian light is similar to lux, but is spectrally weighted towards the portion of the visible spectrum most suited to activating the ipRGCs in your eye, or your circadian system.

This means that a light source that emits let's say 5,000 lux and 4,000 CLA is less effective than a lamp that emits 4,500 lux and 4,500 CLA.

When it comes to white light, these metrics track pretty well with each other, generally more lux means more CLA, but not always!

So just something to be aware of.

Lux per in²

One more thing to keep in mind with a SAD lamp is how comfortable it is, not just how bright and effective it is.

For this reason, I’ve measured each light’s radiating area and calculated the “lux per in²" from each, which gives you an idea of just how much “glare” a light source might have.

There is a better metric for circadian effectiveness anyway... then look for the standout bright lights with low glare, which at this time are the Alaska Northern Light NorthStar and the Carex Classic. These lights offer disproportionately more light output for their size than others.

I personally found that going over a Glare of around 300 starts to get a little uncomfortable. Doable but I prefer equal to or less than.

Note: This is all based on a 1-foot measurement on the brightest setting of course, so you can move things away and dim them to modulate this effect.

Other Stuff

We’ve also tested CRI, color temperature, SPDs or spectral graphs, flicker, and more!

So hopefully this resource will help you objectively find the right SAD lamp if you’re on the hunt for one!

Any suggestions or questions are welcome!

Since I already know people are going to ask, I’m planning on buying and testing the Chroma Sky Portal lights soon!

Looking for recommendations for a seasonal affective disorder lamp for this upcoming winter.
Looking for $25-50 range. Was thinking about one I can wake up to. Thought about one with a timer, then realized I could just pair it with an old- fashioned outlet timer too. Looked on Amazon, but there's too many out there with questionable reviews.

Do you have any recommendations for a SAD (seasonal affective disorder) lamp?

A couple of years ago they all seemed to cost £200+, but today I can see several dozen different cheaper units on Amazon.

Do you have a tried and tested SAD lamp?

What features do you like best about yours?

Is a higher cost justified or can a cheaper unit achieve a similar effect? I'm happy to spend more if it's for the best.

Would very much appreciate your advice!

EDIT: Forgot to mention that I am truly, truly awful waking on dark mornings and would ideally like a lamp which can work on a timer.

Most of the therapeutic SAD lamps are borderline scam. The physics of light therapy: SAD lamp light is ordinary light. There is no such thing as medical grade light. The bulbs/tubes/LEDs in the advertised lamps are the same as in your everyday lamp. Melanopsin is excited most by light at 480nm (blue). You want a lamp that emits a lot of light around that frequency. The best way is to look at the spectrum of the lamp. Here is an example: https://www.heise.de/ct/imgs/04/2/6/4/1/3/1/2/PhilipsGU10Farbtemperatur_gon_IG-e0e5e1ae487bb1af.jpeg The blue one would be a good fit because of the peak around 480. If that is too technical, generally speaking you want 7000K+ fluorescent tubes (skywhite) or cold white LEDs. 90% of the sold lamps are way too small. They are rated 10000 lux when the light hits your eyes from the front at a distance of 30cm. Light intensity falls off with distance squared, so at a more realistic 60cm you have 2500 lux left. Still looking directly at it. Unless you want to spend an hour every day with a screen in front of your head, you need to go big. My recommendation : build it yourself. 6x36W osram 880 tubes (8000K) do a way better job than a therapy lamp five times as expensive. If you want to buy one, get the brightest, coldest lamp you can find. It doesn't have to be a therapy lamp. Try to find the data sheet and look at the light spectrum. Household lamps don't emit uv radiation, no filter necessary. Do not use LEDs without a diffuser (screen).

A good option could be to get studio lights in the 6500-7000k color range. Usually the studio lights come with stands to elevate them above your head, similar to how the sun normally would be shining on you.

You need a full-spectrum lamp with the right blue wavelengths, and it needs to be at least 10,000 lux in brightness. You want the wavelengths to be rich in the 460nm to 520nm range. You aren't going to find this in a single bulb, but you will in a single fixture. Color temperature is not important for this, but for the right wavelengths you're going to find they're all slightly bluish -- which is what you want. That, or a brilliant white like daylight. Philips makes a number of units. If you're going with LED you may note some of the blue-rich units (with blue LEDs) list their lux values in "scotopic" units. You would do well to ensure they have data supporting the effectiveness of their units. To their credit, Philips has a fair amount of research going on in this area. If you have medical insurance - see if you can get them to pay for it. If you've never been evaluated by a physician who specializes in sleep medicine, I highly recommend it. Personally, I use a big box with a prismatic reflector and (2) 24" long biax full-spectrum fluorescent tubes. ( Like this one ) I prefer it to LED because I can just replace the lamps if any burn out. Many of the LED units will only last 10,000 hours.. (although, who knows about their drivers..) which is a long time, I'll grant you, as that works out to over 50 years of use :) references: http://www.biomedcentral.com/1471-244X/11/17 http://www.sciencedirect.com/science/article/pii/S0165032711004885 http://onlinelibrary.wiley.com/doi/10.1111/j.1600-0447.2009.01345.x/abstract

Lighting Science group has a new product that is intended to address this issue, but I have yet to test it and am waiting on more technical details on what they have done with it. The price take of $39.95 is a little too high imo, and am working on getting these for cheaper from them. https://cdn.shopify.com/s/files/1/0774/5259/files/LS_HEALTH_Awake_Alertv2_Specification_Sheet_REV_A_10-30-2015.pdf?375841814060903926

December 3, 2023 - Consider checking if your local library has a lamp you can check-out. This would allow you to test to see if the light is beneficial for you before paying for your own. I've been using a SAD therapy lamp, and it really seems to have made a difference to my sleep.

r/smarthome on Reddit: Smart bulbs to help with seasonal affective disorder
January 6, 2020 -

I live in upstate NY, so I don’t plan on seeing the sun until mid-April. I currently have some smart bulbs in the lamps next to my bed, and they fade in as I wake up in the morning. The only problem is, these bulbs are just one standard color, and I know that lights that help with SAD are recommended to be a blue-ish hue.

Does anyone have any experience with or recommendations for this? I would assume that any smart light bulb with a decent color selection could probably get the job done, but I figured I would ask here first just in case there is a particular bulb that seems to get the color just right.

Thanks in advance!

September 1, 2020 -

I recently moved north of the 45th parallel (US), and as the weather has already started to turn I'm concerned about my seasonal affective disorder getting unmanageable (I've always just relied on vitamin D supplements). I also have a delayed sleep cycle (longer than 24 hours) and years ago a sleep neurologist suggested getting a sun lamp but I never did because the costs were just too high. Any suggestions for budget friendly lamps that actually work?

I picked up one of those bright therapy lights for seasonal depression this week, and honestly… I didn’t realize how much the darkness was affecting me until now. Within a few days, I’ve felt my mornings shift less groggy, more focused, and even my cravings for dopamine hits feel lower.

If anyone’s been feeling that winter slump or low motivation after quitting weed/caffeine/etc., this thing legit helps. I just sit in front of it for 15–20 minutes in the morning while I journal or drink my shake.

Not a cure-all, but definitely a game changer for energy and mood. Anyone else tried one of these yet??

What are the best budget friendly SAD lamps? : r/SeasonalAffective
October 22, 2025 - Share ... Look for lamps that are 10,000 lux or you won’t get therapeutic benefit and there’s no point in spending the money. From there, with larger (presumably more expensive) lamps maybe you don’t have to sit quite as close or maybe not quite as long as with smaller ones.
