Light Therapy Lamp, SMY Blue Light Energy Lamp and Adjustable LED Blue Light, Tablet One Touch with Timer, 100% UV Free

Very high quality bright blue light. I believe this matches the 200 Blue light lux output seen in many experiments.Things that weren't immediately obvious to me:1. It has an extremely small form factor. The kickstand collapses conveniently into the back, giving this a shape that's basically like a thick tablet. This makes it very easy to pack in, say, a laptop bag or similar. Some light therapy devices are bulky and awkardly shaped, not this one.2. The USB power port make it very easy to use on the go. You can just connect it to your laptop or a portable battery and power it, no need for some hulking power cord and outlet. The device says it's rated for 1 amp, which basically all modern chargers and ports can accommodate.3. The timer setting is optional. If you want the light to stay on as long as you want, you can. I like to use mine for several hours in the morning, so it's good that you don't have to cycle it.Not so good:4. The "low-light" setting feels like it's about 80% the standard level. So you've got "super-bright, pretty-darn bright, and off" as your options. Doesn't bother me as I like the standard, super-bright setting, but if you want lower intensities go elsewhere.5. As this has no mechanical switches, you aren't going to be able to set this to "on", connect this to an outlet timer and use it to turn on automatically at a specific time as part of a wake-up alarm. Which is a real disappointment.UPDATE: I purchased a second unit January 2021. The model has been updated slightly. It now uses a USB-C type connector in the back instead of a USB micro and features a small SMY logo on the top despite the same model number on the back label. Personally I don't like the SMY logo, but it's small enough in a light font that it's not too bothersome. The light intensity and other elements appear unchanged.UPDATE: July 2022- I continue to use both units with my laptop for around 6 hours a day in the early morning. They can be powered over an unpowered USB hub connected to a laptop, and even run off of a mobile power bank. The older one is slightly more dim than the newer one, but it's really only noticeable compared side to side. These do not have limitless lifespan and after several thousand hours of use would be expected to dim a bit. I don't see this impacting their usefulness for at least a few years.UPDATE: November 2022- Lights continue working well.ISSUE- The USB-C lamp appears to not be able to power off of all kinds of ports. A USB laptop charger (USB-PD) with a type C plug appears not to be able to power this. Also connecting this to a type C port on a Microsoft Edge 2 with a USB C port, either directly, through an unpowered hub or through a usb C to type A dongle does not work, but the USB microlamp can be powered with an adapter USB C to USB micro. I think the USB-C lamp then needs whatever power typically comes out of the type A ports (the fatter wider plugs).This is notable because it makes powering the USB-C lamp on the go slightly more challenging if you are not also using a device like a laptop that has a USB-A plug.Your options to power the USB-C lamp then are:>Have a laptop with a type A port and plug in the lamp directly or through a hub>Carry an ordinary USB A power adapter and plug that in where you have an outlet (easy but you may be in a spot without an outlet or limited outlets)>Hope you're in a place with powered USB-A ports (not uncommon on planes, airports and hotels)>Carry around an external USB battery pack and power the lights off of that (works, but your battery may need to be relatively large to power two of these for a long morning. I believe the devices consume substantially less than the 1A they are rated for, don't recall what it is)

Please be sure to follow the instructions on how to use this product. I have used a white therapy box in the past and this blue lamp is much lighter and easier to use. The blue light is a definite improvement and I have found I have more energy and my sleep schedule has improved. I look forward to using this each morning and even if my wake time is earlier or later the results remain stable. The quality, performance and price are all great and I look forward to an easier New England winter. I like the USB port and cable, setup and buttons are very easy to use.

Product light and easy to use. Takes a small space. 2 settings is good at night I put in on dim.

I have three of these now. I try to use them in the morning when I first wake up. They seem to help greatly reduce my daytime sleepiness. I love that they are USB powered. (USB-A 1amp but 500 milliamps works well, too. It comes with a cable and US ac 5volt USB power supply.)I love the blue light and the fact that it blocks the UV-B, which is said to be harmful. Using this help to reset my body clock so my brain knows when it is day or night. I seldom get outside to get natural sunlight and I have no windows in my office, so this helps me a lot. Got SAD? Try this!

The light is nice and bright and I'm using it daily. The timer is poorly engineered and I find it almost unusable. You cannot set the timer until the light is on. Once the light is on, I cannot see the indicator for the timer (you push it 1-3 times to select the time). The switch should be a slide switch so you can set the timer BEFORE turning on the light. Otherwise, it seems to work as advertised.

I got this after seeing a coworker with an old school light box on their desk. She said it helped with her S.A.D., something we get a lot of here in Seattle. I went online and read up on it and decided to try the blue one, since that also happens to be my favorite color.The device is super portable, about the size of a Kindle reader. Love that it is powered by a USB plug. This allows me to use it with a simple battery pack most everyone has now for cell phones.I tend to be a night owl and hate hearing those early morning alarms for work. Decided to see if this could help be adjust my sleep cycle, too. Been using it daily and saw results in the first two days for this. I actually get tired earlier at night and wake up feeling more alert. I use it 30 minutes every morning within an hour of waking up.Will see how it does on S.A.D. now that the days are getting shorter.It seems like a well made product. Nothing about it makes it feel lux or worth the price it is. But as long as it keeps lighting up my day I am happy!

Improved mood and sleep

I ordered the SMY BLUE ENERGY LAMP in March, 2022. The lamp worked as described for two years and eleven months. Suddenly, the lamp would not turn on for no apparent reason. I utilized it primarily during the Central Daylight Savings month. Consequently, I can not recommend it due to such a short life span.
