Benefits of Bright Light Therapy
Light therapy directly affects your internal body clock, also called your Circadian Rhythm. When it’s time to wake up, your sleep hormone melatonin plummets and your stress hormone cortisol rises.
Bright light is the signal that regulates this process. our lamp provides this bright light when you can’t get it naturally; either because it’s too dark outside or if you are unable to spend time outdoors.

When I found the Lumos on Amazon, I jumped on it. I bought my first lamp in October 2017, and I liked it so much that I bought another one shortly thereafter. I've been a happy camper until this week, when I turned on my lamps. To my dismay, one of them flickered for a bit and went dark. After trying it in different sockets, I contacted the company asking what I needed to do to have the lamp serviced under warranty.
The company responded right away with good news and bad news. The good news was that they would be happy to replace the lamp for me, but the bad news was that they were out of stock and it would take a while before they could send me a replacement. They gracefully offered a new lamp of one of their remaining models or, if I preferred, a full refund. I really like this particular lamp though, so I asked whether they would agree to extend the original warranty term by the duration of the wait, which they had no problem with. I don't mind waiting a few weeks if it means I get my Lumos replaced with another, since this is the one model that works best for me.
In a nutshell, I love the lamp(s), and the company's service is stellar. Can we have more companies like this around, please?

It's a waste for me now.
Product description doesn't mention about the side effects mentioned in the manual.

I wanted a light therapy lamp but I didn’t want a chunky light box sitting on my table, especially when not in use, so I really like the slim design of this light. It is also a lot smaller than the typical, bigger light boxes so I appreciate the smaller footprint. I like that the lamp will swivel to get the light stream just right depending on how close I’m sitting, and the ability to choose from three output settings is a nice since I won’t always want/need the high settings when using later in the day. The light also looks sleek when closed, which is a bonus.
Even though the lamp is smaller than others in this price range (under $75), I found it to be quite sturdy. I was worried it might look or feel “cheap” but it is actually well built and, dare I say, stylish? Overall I am satisfied with this purchase and hope to see the benefits of using it over the next few weeks.
•••11/2/17 UPDATE•••
I still love this lamp after a week and a half of use, however I thought I would mention that the lamp is tall and thin and tends to be top heavy if you have the arm with the lamp extended. The product description mentions the lamp being configurable and adjustable to a variety of positions and, though this is true, the lamp is the most sturdy when the light is set up so that the "arm" piece is vertical and close to the body of the lamp. I had this on my night stand and used it to wake up in the mornings but I had problems with the lamp tipping over with the slightest touch do to being top heavy with the arm more extended - which was my preferred set up for early mornings. I still love the lamp but am trying to get used to using it like the picture in the product description, which can be very bright depending on where you are using the lamp. I did not deduct a star as this lamp was still reasonably priced and much more stylish and compact than other light therapy lamps. So this update is more of an FYI for folks who are considering this lamp.
FYI - Some reviews and info in the product Q&A mentioned usb charging and/or the ability to use this lamp unplugged via its built in battery. The lamp I received (10/2017) has a normal ac adapter and not a usb cord. It also does not appear to work when unplugged and/or include a battery for use when unplugged. I don’t know where the confusion comes from but I wanted to at least mention this in case someone was expecting to use the lamp wirelessly.
Lastly, The brief manual that’s included provides basic instructions, usage info, specifications and a few FAQs. There isn’t a ton of info but it’s enough to get you started.
