A rather large desk lamp. 21 inches high and the base is 11 inches in diameter. Weighs 21 lbs. Two circular fluorescent tubes each 70 watts, each rated at 4290 initial lumens. One tube mainly illuminates below, the other above to provide indirect light from ceiling. This type of fluorescent tube has 10,000 hour life and the lumens decline quickly. Mean lumens probably 85% of initial lumens. Replacement tubes are expensive. Tubes can be independently dimmed to 25%.Arrived in two boxes, one box for shade. Box and shade were dented but dent could be pushed out. When placed on white table with white ceiling recorded1000 lux at 2 feet from center of lamp and 240 lux at 4 feet (both tubes illuminated). Very good for illuminating writing desk and provides fair area illumination. Would be good in dorm room or on any reasonably sized desk. Total illumination equal to 5, 100-watt incandescent bulbs.
