After my doctor recommended I try a light therapy box to help mitigate the effects of the sometimes short, gloomy days, I found the Carex Day-Light Elite lamp which, despite the company not advertising this fact, works perfectly with a standard 100mm VESA mount. It’s mounted to the desk with an adjustable Ergounion E6 monitor mount with extension arm. During the day, when it’s not pointed at me, it’s pointed at the ceiling. Even at 50% intensity, the reflected cool white light really brightens the space.
