Economical and elegant, the Unilux Joker 2.0 LED Desk Lamp boasts an asymmetrical diffuser which eliminates glare and thus limits the strain on your eyes and consequent headaches. Equipped with a built-in LED unit, the lamp allows users to save in both maintenance and energy costs: it produces a pleasant warm light that is brighter than that of other bulbs, but consumes very little electricity and has a much longer shelf life in comparison. Users can also vary the brightness of the light: the variator switch on the base of the lamp allows you to switch between 0%, 70% and 100% luminous intensity. The head and the arm of the lamp can both also be tilted easily to redirect the light when needed.
