1) My internal clock is skewed: I'd prefer to go to bed at 3 am and wake up at 11. I've never been a "morning person."
2) I work in a dreary, cubicle-filled, fluorescent-lit office for 8-9 hours a day, nowhere near a window.
This past November, I did several days' worth of research into SAD and related conditions (my internal clock is connected to SAD!) and eventually decided I was a reasonable candidate for light therapy. I had been eyeing this Zadro Sunlight unit, and when it went on sale before the holidays, I bought it. (Might as well start small, right? What if it ended up not working? I didn't want to waste hundreds of dollars on a huge designer SAD light. The Zadro unit fit the bill, literally.)
I can honestly say that it has worked, but it took about 4 weeks of daily use for me to notice a big change. The human brain interprets blue LED light as sunlight, and that's why this unit is effective. I find the strongest light intensity (100%) to be too great, so I set it to 50% and leave it on for 60 minutes in the morning at my desk. It has noticeably helped me feel happier and more alert. Surprisingly (I was doubtful I would see any effect), it has helped regulate my internal clock: I wake up more easily in the morning, get hungry at normal times (noon instead of 2:00 pm), and start to feel tired around 10:30-11:00 pm. It's a huge difference.Read more ›
I was so tired and low on energy before I got this, increasing my coffee intake little by little, and it wasn't helping. This light resets your body clock. I can feel it happening immediately. Suddenly I'm awake and completely "on it" and feeling clear and attentive at 8AM. That is NOT typical for me. And I get tired at the appropriate time at night. I have real, normal energy, not like nervous caffeine energy. I've been getting a ton of work done, on the job and at home since I got this about 3 weeks ago.
I can't recommend this product highly enough. Its small, and portable. Its also the cheapest light on here, and I really don't know what the other lights can do that would be better. This thing is very bright, and its that blue spectrum light that causes the brain reactions that you want to achieve. You can program it for a time and intensity, or just manually set it. The casing is a little flimsy--the stand broke after just a couple weeks for no reason, but I put a piece of tape on it and its fine.
I find that it has allowed me to shift my circadian rhythm during the week, so I now find it easier to go to sleep earlier and wake up more easily before my alarm goes off. Whether it's brightened my mood is still pretty unclear. It certainly hasn't made it darker, but I don't feel like I'm a brighter, more cheerful person either. I do find that as I use it for longer periods of time that I do feel a bit more wired and energetic, but as mentioned above it's still early times for me.
One thing that's worth mentioning is that it is quite low powered compared to the lights that have been used in most of the light therapy studies that have been written up and are available on the web. I measured the output with a simple lux meter and found that it was about 300 lux at a distance of 24 inches. You have to press the lux meter directly against the LEDs to get to the 10,000 lux rating that is mentioned by the manufacturer. Once I figured this out I modified the way I use it. I now do 30 minutes with the Zadro at 2 feet and 100% brightness when I first wake up in the morning at around 5:30.Read more ›

This worked for about a month. I had it in the same place and used it daily. I moved it to a new outlet, used it once and moved it back to the original spot and it hasn't worked... Read morePublished 19 days ago by Gina Strand
Effective but poorly made. Good way to try out light therapy before buying a better unit, and judging by other reviews, a good percentage of the units are not defective. Read morePublished 24 days ago by Joshua A. Tenpenny
