I've been testing out this lamp for a couple weeks now. Before getting this lamp I was using (besides my overhead light) 2 name brand desk lamps and I would throw in a mini spot light for detail work. This lamp will take the place of all three! The 3000 lux lights up nearly my whole 3 x 5' desktop and it's so easy to grab the head and adjust it to exactly where I need the light. My other main desk lamp took two hands. I'm blown away at all the features. To be able to adjust the brightness and color range is incredible. With 95 CRI I can see the true color of my materials and get the most accurate color in my photos.
