  • It's already helping our daughter and has a great design/size.
Per a recommendation from our doctor, we purchased this for our daughter who suffers from depression. The darker winter months here in the northeast have always been tough for her, but this awful winter has made it almost unbearable for her. After doing some research, we decided on this model and are very pleased so far. Since the booklet enclosed advised that you start off using the filter, that's what we did. The filter casts a nice soft glow. However, it also cuts down on the light effect. After a day or two, we removed the filter and she's been using the light on the highest setting. It took some getting used to at first, but now she's fine with it and states that she feels a difference already after using it a week. Things that we like about this model: - We like that it emits the highest suggested amount of light (10,000) while also giving you the choice of a lower setting as well as a filter to soften the light. The variations of lighting ensures a "prefect fit" for everyone. - We love the compactness of it! It doesn't take up a lot of room and can easily be placed in a convenient location in the house. Our daughter, who often lays on her bed to text and talk to her friends on her phone, has it on her nightstand beside her bed. In the mornings, she puts it near her while putting on her make-up. Rather than disrupting her life, it fits right in! A sure way of ensuring that she uses it. - The tilting feature allows you to position it perfectly for your needs. - It's a snap to remove the filter or put it back on. It literally takes about fifteen seconds. - We love how durable it is. It seems to be well made and should last awhile. - We like the option of being able to hang it on the wall if we would choose. - Verilux is the top name when it comes to energy lamps and has a great reputation. That put our minds at ease that we were purchasing a good product. I would certainly recommend this product to anyone suffering from depression or seasonal "blues". It seems to be helping our daughter and the only regret we have is that we didn't purchase it sooner. ... show more

  • This did make a difference. I started out with only 10" at a time. More energy and a mood boost!!
One day this Spring, after endless day after day after day of clouds/rain/grey skies I'd about had it. Finally got this light box after thinking about it for awhile - now wish I would have gotten it much sooner, back in the middle of winter! I definitely noticed an improvement in my mood and energy level - I can actually "feel" the light working - that sounds crazy, but it's true! I started out with just 5" at a time, then upped it to 10" after a couple days, and gradually worked my way up to 20-30" at a time. I never had any issues with headache or nausea; I think if I had started out with 30" right away I might have? Instructions say do NOT look directly at the light. DON'T. I even look away slightly when moving it/adjusting it/turning it on/off. I set this off to the side on my nightstand and first thing in the morning turned it on and read a little bit, scrolled though my phone, had some coffee - whatever - while this light was on. That's all it takes! Definite energy and mood boost. I read up a little on how this works, I sort of understand it, but doesn't matter - it works. It's fairly compact, I wouldn't say small, but fits on my nightstand. Definitely recommend! ... show more

  • Works great although there is an internal screw that jingles inside of the divice
I like the brightness, lightweightness and ease of use. It has two settings and I find myself only ever using the brightest setting. It definitely improves the vibe of my dark and dreary apartment. The one issue I have with it is that there is a screw inside that jingles around.

  • Comfort lens vs high-intensity
I don't know why it took me so long to look into getting a full spectrum light and have light therapy despite knowing that my mood turns down every fall and winter. I've been using this lamp about 5-6 times a week for about 3 weeks now and it has really improved my mood, so much so that I plan on discussing with my therapist easing off my medications next appointment. And thanks to improved mood, I have more energy and follow-through on those "best laid plans" that I always end up finding excuses not to do when I'm feeling depressed, like going for a hike or quick walk, or socializing with girlfriends. And this ends up snowballing the positive effects, b/c of the additional exercise and social connectivity, I'm also feeling better. The lamp itself is small enough not to take up a huge footprint on your desk or counter. It has a long power cord, so it can reach outlets further away. The lamp swivels forward and back in its base, so you can place it on a surface above or below eye level and adjust its position accordingly. I often use it in the kitchen while I'm prepping meals--you can easily get in 10-20 minutes of light therapy while chopping, sauteeing onions, and packing the kids' lunches. I also get in some light therapy by moving the lamp (again, bonus for being a lightweight and small device) next to my desk and getting some rays while I binge watch Netflix, read the news, or watch a few clips on YouTube. Which brings me to my next point, don't feel like you have to sit down and do a one hour session at some appointed time daily. You can break up the light exposure into 10-20 minute increments, mimicking your exposure to actual sunlight during a summer day when might go in and outdoors throughout the day. You should not stare at the light itself; the lamp should however be pointed somewhere towards the front of your face. There is only one switch, which turns the device off, high, and low. And there are two lenses (the plastic covering to the bulb) which can be snapped on and off pretty easily and are held in place magnetically: the high-intensity lens and the comfort lens. The amount of light you can receive on this light are as follows: High energy lens on high setting: 10,000 LUX High energy lens on low setting: 7,500 LUX Comfort lens on high setting: 5,000 LUX Comfort lens on low setting: 3,500 LUX For perspective, a clear spring morning sunshine gives you around 10,000 LUX while exposure to the sun at noon on a summer day is over 100,000 LUX. My therapist and numerous studies say that you need a lamp to provide at LEAST 10,000 LUX to be therapeutically effective, but I recommend experimenting with the levels and exposure. For some people, the bright light can give headaches or nausea. The product manual recommends for those folks to start low and work your way up to higher light settings. You should also consider the time of day that you are using the light. I like to use a high setting during the morning, but if it's already 6 pm when I get to sit down in front of Netflix (and it's already past sunset outside), I'll turn on the light on the lowest setting so I get some exposure. You don't want to use the lights too late into the evening or you'll mess with your internal circadian system and make it difficult to regulate sleep. I just try to use the lamp to mimic a late spring/early summer day during these fall and winter months. Final warning, my therapist was adamant to warn that those suffering from bi-polar disorders have been shown to be negatively impacted by using light therapy. So if that applies to you, approach with caution. If you found this review helpful or have questions, please let me know! ... show more
