Circadian OpticsLight Therapy Lamp | Ultra Bright 10,000 Lux Full Spectrum UV-Free LED Light | Leo

For those reading reviews and fretting over the “dots”, don't be. Used correctly (off to the side while you're paying attention to something else), you'll barely notice the individual LEDs, and they have no negative effect on the effectiveness of this as a light source. And so far, every LED based SAD lamp I've seen has them, so it's obviously not an issue. It's not a distraction if you're not looking straight at it, and you shouldn't be anyway.This is the third light therapy lamp I've owned, and by far it's my favorite. My previous two were smaller and travel friendly, and they were effective enough to be noticeable. This year though, I'm battling not only seasonal light issues and chronic depression, but grief on top of both of those, and the little travel light wasn't having a noticeable effect. Reading up on some studies, I found that this is a case where “size matters”—the most effective lamps of this sort are the larger ones. Because I use mine in the living room, I wanted something that looked attractive and not at all like a light therapy box. Circadian Optics Lattis model was my first choice, but after reading about size, I opted for the less fancy but bigger Lampu instead.And I have zero regrets. The Lampu model has three light levels, and is so bright I had to start off at medium for a few sessions and keep them short even though I had been using another lamp for three weeks. Nowadays, I can comfortably sit with it for an hour at a time on the highest level. The light angle is perfect for sitting and reading or writing while you soak in the rays—I'm writing this review while sitting with it, three months after purchase. The on/off function that barely needs to be brushed against took some getting used to, but it's actually very easy to use now. I do wish it had a built in timer, but that's a small complaint for a device that has proven to be very effective against my seasonal issues. If your only problem is seasonal depression, spending enough time with this should wipe it out. If like me, you have other depressive disorders, this should at least take the added seasonal component away so you're not dealing with compounded effects. (Either way, do get your vitamin D levels tested. Most people in the Northern Hemisphere are deficient to some extent, and that will contribute to many forms of depression.)It's lightweight, but very stable, so it's easily moved. And it's attractive enough that recent houseguests didn't recognize it for what it was until I went to use it. Best of all, it's an effective tool against seasonal depression. Easily in my top five things I've bought this year, and well worth the money.

I purchased this Circadian Optics light after buying (and then returning!) two lights by another leading manufacturer. Both of those lights had faulty power buttons right out of the box, so I had to send them back immediately without ever getting a chance to use them. Needless to say, I lost all faith in that brand and I decided to give Circadian Optics a try. I'm so glad I did, because this light is perfect for my needs.Right out of the box, it's easy to work with. I like the simple one-button design. No finger pressure is required, just a feather-light touch. Touch it once to turn the light on at its brightest setting. Touch it another two times to experience the two less-bright settings. Touch it a fourth time to turn it off completely.The unit is short and squat, so it is unlikely to get knocked over by your own hand or by your cat or dog. This is a huge selling point for me, because whenever my cat jumps up on my desk, she loves to rub her cheeks on any object that is roughly the height of her head, such as the corner of my laptop screen when I'm trying to type. If this were a taller light, she would probably push her head against it and knock it over.This model has no color-adjusting settings or automatic timer, but I really don't think such settings are necessary. This is a neutral, pure white light that I think it very pleasing. The purpose is to help wake you up and keep you alert, and it does exactly what it's supposed to do. If you really want to set a timer to help you get the proper dosage of light, use your cell phone, your computer, your kitchen timer, or whatever else you have on hand.This light has only one drawback I can think of, but it's extremely minor. The base of the lamp is very smooth, so the unit tends to slide or skid when you brush against it with your hand. I remedied this problem right away by attaching three small self-adhesive bumpers made by 3M. Some people call those things rubber feet or rubber bumpers. You can buy them on Amazon or even at the supermarket if you look in the hardware section. Just get the kind that are very small and flat.All in all, I love this light and I am so pleased by how functional it is. It's a great value for the money too.

Do your research. Almost none of these inexpensive lights are 10,000 lux. Including the ones by other well known companies. Nerdy YouTube researchers prove this. They are most often in the 3-5k range, which is morning sunlight not high noon sunlight. So knowing that i bought 2. And i am happy with the brightness and light. I do not like the angle because the light should be shining DOWN not up. The easy remedy is place it higher than eyes and tilt, using tape off you need to.I like the small footprint and the quality of the build. I did drop it twice and nothing shattered or cracked or broke. It has no timer so you can use it a long time as ambient lighting, but be cautious of overheating after a few hours. The light color is very mid spectrum on the blue side. I am very happy i bought 2. But i can not give it 5 stars because it is not 10,000 lux per researchers. But do i want high noon light at 7am? No I do not. I am happy with my purchase.
