In my 73 years of life I cannot recall any other time when I was excited and delighted by a desk lamp--before now. This Taotronics LED desk lamp is truly the one I never knew I was looking for.The engineering is brilliant--at least for my needs. Both the vertical arm AND the light arm are constructed of very sturdy aluminum plate that is less than 1/4" thick. This means that it can sit in front of two side-by-side monitors and beneath another one while barely obstructing vision. (see photo)The 48 LEDs are embedded flush inside the light arm without adding any thickness. (How did they even do that?) Again, the less-than-1/4" thickness does not significantly obstruct vision, even at the top. Since I also have a monitor above my main monitor, this means I can place the light centered directly above the main monitor without blocking either monitor.The height of the support arm is just under 18", which is perfect for the height of my large monitor without being so tall that the light shines into my eyes.This lamp is so perfectly unobtrusive that I'll bet it takes you a while of looking to EVEN SPOT IT in the photo of my desk setup.-- Was I right? It is as though an engineer came into my office, then designed the PERFECT light just for me. Truly, I never would have come up with such a perfect design, no matter how large the engineering budget had been.BUT NOW TO THE GOOD PARTS: * It has 6 brightness settings. Since my office is on an east window wall, I get much brightness in the morning, minimal in the afternoon and evening. It is wonderful to be able to adjust the light level to compensate for the changing ambient. Also, the brightness changes ramp up and down which is more soothing than sudden intensity changes. * It has three color setting--white, yellow and a blend of both. Combining this with the 6 brightness settings gives you 18 combinations to choose from. This means you can find the one that suits your immediate mood and stress level, producing a more calming--or a more exciting environment--as your needs change. * Once you have found just the right setting, the lamp will remember when you turn it off and on. (Personally, I like to ramp it down to the lowest intensity before I turn it off so that it comes on softly next time I turn it on.) * The base is flat and constructed of steel. If you tend to clutter the surface of your desk like I do mine, this means that you can lay objects onto it's flat surface, plus stick any important papers to it with magnets. * You'll love that it has a USB power port on the base. It is a convenient way to re-charge your phone, tablet or phablet without needing to fill one (or two, if your charger is large) of those valuable outlets near your desk with a charger.BOTTOM LINE is that I truly love this desk lamp. I plan to get another for my wife's desk, and two more for our bedroom.It will be absolutely ideal for bedside use as well as for desks.This technology is so ideal for lighting that I envision a time when Taotronics adapts their brilliant technology to room lighting. How great would it be to have an array of super-thin, cool-running, fully adjustable, economical, environmentally-supportive ceiling and wall panels in our homes and office, as well as on our desks?MEANWHILE, get yourself some of these ideal desk lamps. This is a true example of the FUTURE OF LIGHTING!
