UV-Free 10000 Lux Light Therapy Lamp - Adjustable Brightness & Timer Memory | Sun Lamp for Seasonal Affective Disorder (SAD), Energy Boost & Vitamin D | Perfect for Home Office, Bedroom & Winter Blues Relief (White)

Size & weight. Using it for depression.I actually really liked this lamp...at first. But after using it for only 4 months it broke completely. it will not turn on at all. I didn't drop it. I didn't overuse it. In fact, I only used it a few times here and there during the darker months in the winter. I tried to turn it on today and nothing. I contacted Amazon and they won't replace it or return it. Sun therapy lamps work just not this brand. Save your money and buy another company.This works well for what it is supposed to. The 3 different color temperatures is an interesting concept since one specific temperature helps best for helping cure afternoon tiredness or winter doldrums. I suppose they intended it to be used as just a normal lamp, as well. (It does fine in that regard.) The display is not the best in the world, but it gets the job done.If you haven't used a light therapy lamp before, it's important to note that for therapy lights to be effective, they have to be pretty close to your face. While using one at work (I used to get crazy tired around 2pm) I kept it slightly closer than arm's reach and had it turned up to its brightest setting. Yes it's bright. Yes, it can be distracting. But that was what made it effective for me. Made a big difference in my afternoon sleepiness. YMMV.Overall, a pretty good therapy lamp. It's slightly cheaper than the name brand models out there, so that's good. At this price point it *might* be better to stretch a little more and get a model that's established, but unless it fails prematurely this should get the job done for you.Review for: Light Therapy Lamp Easy@Home UV-Free 10000 Lux Happy Light Therapy Lamp | Sun Lamp with 3 Color Adjustable Brightness Levels Timer Memory Function，ELT-492-WTIf all you want to do is turn this light on and off as needed, you will probably very happy with this light. If you want to set the timer for different times or to use the sunset option, it is a bit more complicated. Both of these scenarios means you need to remember the combination of buttons to push to get the desired results. In the lights defense, once you set the timer, the memory function will keep it as the expected setting as well as your brightness setting. If you change it, that is your new memory setting. Changing up the setting is not difficult, just tedious and you might want the instructions handy for a while. I found the sunset setting to be a really nice feature, once you figure out how to start it.The light can be used in either a horizontal or vertical position. The stand is built into the back of the frame. It comes with a cord for your electrical outlet but that cord could be longer for my preference. The light has plenty of brightness settings, including one that is quite dim and easy on the eyes. The light is full spectrum.This is a feature rich light therapy device. It's a nice size, perfect for a desktop or side table. This type of lamp is great for the late fall/winter season when there's much less sunlight. Or, if you spend most of your time in a room with little access to natural sunlight. Studies have shown that exposure to proper temperature lighting affects mood, sleep and concentration/focus. Lamps like this address that by simulating the appropriate lighting.This lamp has the usual trio of lighting (which they term as : White, Warm and Warm Yellow). And they have dimming/brightening steps for the brightness levels of each. With a long press of the brightness button, you have stepless adjustment of the brightness intensity, with a considerable range of 5% - 100%.Timing can be set to a user customizable setting, or turned off. (the manual does not give a limit on the timer, but the product details has a chart that states the time can be personalized from 1 minute to 6000 minutes!!!).The lamp has a special Sunset Mode, accessed by pressing the Timer and Brightness buttons simultaneously. In this mode, the lamp gradually dims, until it powers off after 20 minutes. This is an interesting feature, which simulates the gentle transitioning from daylight.Due to these customizable aspects, the inclusion of a display is a necessity. Thus you are able to confirm the settings/timing options. However, when the lamp is operating, it's very difficult to read the display, due to the brightness of the lamp. I had to use a magazine to block the light to read the display. To be fair, I don't know how they can reconcile the issue. Putting it on the back of the lamp might be a viable solution, though. But, that might be counter-intuitive to general lamp control/operation.I found this to be a very credible light therapy lamp, with an abundance of features. I like the size and light weight aspects. Based on these observations, it earns a 4.5 - 4.75 star rating, with a high level recommendation.The direction of our house makes it so that we can get bright natural light in nearly every room of the house except the living room, where it always seems a little too dim. I love this light for providing what feels like natural light, particularly on cold, dreary days. There are three light types to choose from, with each having multiple levels of brightness. I particularly like the bright white light, though it is very bright if you look directly at it (or even when it's in your peripheral vision). I like to set up the light behind an arm chair in the living room. This helps brighten the room without putting it directly in anyone's face. I find that the light therapy really does help to brighten my mood.Man, these things are hard to review for efficacy. How do you really know it's working? All I can say is that I have never felt sad when its turned on. I place it kitty corner to me when using my laptop. You are not supposed to stare straight into it. I love how it can do both warm or cool tones of white and adjustable brightness. It is very lightweight though it needs to be plugged in at all times when in use. Give it a try!
