Northern Light Technologies Boxelite - 10000 Lux Light Therapy Lamp - Full Spectrum Lightbox Therapy Light for Natural Mood and Energy Enhancement, Sunlight Desk Lamp, Black

The screw is misleading and I think that's why some reviewers thought the screw was missing. It is the white plastic screw that comes attached on the base of the light box. Unscrew it and place the metal stand on the box. Tighten the screw in place with a coin. Be careful because the edges of the box are very sharp.This is my second day using this light box. I couldn't tell much on the first day. Then I realized that you need to be 17" from the light box. That is really close! I pulled out the tape measure and discovered it's much closer than is shown in that picture of the guy sitting at his desk. Now I'm sitting really close to the lamp while on my phone checking emails, and periodically changing my position so that both sides of my face have the advantage of being near the lamp. The instructions say not to look into the lamp very often...especially if you have light colored eyes (blue or green). So, I just take a quick glance every once in a while. So far I'm feeling like I have more energy...but I also drank caffeinated tea. So I can't say for sure. But, I do like the brightness of the light. It lights up the room pretty well, which is nice since I live in Portland, OR and it's always cloudy and raining, which keeps my home dimly light. Though, it's probably not a good idea to keep this light box on for very long periods of time since the instructions say that after 20,000 hours of use it will emit 15% less light, and should be replaced. It uses two 36 watt tubes that can be purchased from Northern Light Technologies.Oh one other thing...when you first turn on the light box it takes about three seconds before it turns on. Make sure to turn your head and look away from it because it's BRIGHT! I made the mistake of turning my head back towards the light box right when it turned on and almost fell over in shock. It's bright!...can also be used for lighting up stuff you're trying to photograph.

It'll take up a fair bit of space on your desk, but that's the necessary tradeoff for a light with sufficient intensity and coverage. Compared to other desk lights of this nature, this is my favorite I've tried. A number of reviewers have noted the "clicking" sound that the light makes when warming up and cooling down. The noise didn't bother me much, but I was curious to try to make it go away anyway, as it can continue for quite a while even after the light is off. I played around with the light a little, and ultimately was able to eliminate the noise completely simply by loosening the four screws on the front plate.

This thing will burn your retinas if you put it right in front of your face like how other brands require it, but unlike those other brands, this light you can actually put at a distance about a foot away and still get 100% therapeutic effect. Also let's be honest, the other brands usually require unreasonable conditions such as being less than 6 inches away from the light source or else it loses effectiveness, which is hard to do without being disruptive. Boxelite truly allows for good light shining through from a distance away.

I spend time on both sides of the Atlantic and have had a light like this one overseas that has proven effective for years. So i wanted one in the usa, where i got “stuck” due to Covid that was similarly large though i’ve never tried small ones. i opted for this (more expensive than alternatives) option because the specs were slightly better and because it is made in north america (canada, i believe). I was bit disappointed because the unit arrived missing its foot bracket, hence a 4 rather than 5 star review. A call to the service number included and a week later i had it in the mail. Fits easily and functions well.

Excitedly unboxed my unit today when it arrived ... to find I have been sold a 110v unit with a US-Canada plug. I live in Australia, and the delivery address was in Australia. We have 240v power in Australia (most of the world have 220-240v) and an entirely different power plug. Nothing in the product description mentions the unit is 110v only. To even plug in the unit, I have to get back on line and find and order a voltage and plug converter, at additional cost beyond what i thought i was buying, and now wait another week for delivery. Marketing and selling electrical products internationally should respect international power requirements, and either sell appropriately modified units or include a voltage and plug converter in the sale. OR at VERY LEAST, clearly specify what is being sold. Product description only mentions 'corded power'. Poor ... very very poor

TL;DR: This thing works. It has changed my mind and my life.With both long-term Major Depression Disorder/Seasonal Affective *and* newly diagnosed Fibromyalgia, several of my psych med managers over the years suggested I give light therapy a try. I knew that sunny days had a pretty drastic effect on my mood and pain levels (serotonin increase), but would artificial light replicate the results? I was extremely skeptical, but spending half this winter laid up in bed, I decided I was willing to try anything.I received the unit quickly after ordering it, and setting it up with the single thumbscrew was very easy. I set it on the desk in my office just about 12" away and turned it on. The effect, for me, was almost immediate: the same kind of mood boost you get when you walk outside on a sunny day and look up and get a face full of sunshine. I can't explain it better than that. I now spend at least 15-20 minutes a day sitting next to it before work; on the days I work from home, I am in front of it all the time.My mood is better, more even and just happier. My pain level is also lower - there are Fibro studies that show links to serotonin and other neurochemicals. I can't speak for anyone else definitively, but anyone who has rainy day/winter blues or Fibro really needs to at least give this a try. Really.My only complaint is that there is no way easy way that I've found so far to mount it on a wall or in a corner, so it can shine down - it takes up a good bit of desk real estate.
