The original Z-Bar design was Koncept’s flagship product in 2004. Koncept designers have since created a dynamic and successful family of Z-Bar products, including a floor lamp, wall sconce, pendant line, and other desk lamps. Gen 4 is the fourth revamp of the original Z-Bar Desk Lamp. An improved joint design allows for a cleaner profile. It can now fold up to a slim stick when not in use. The optics are improved so that multiple, harsh shadows are avoided, instead giving the user soft, even shadows. Another new feature is a USB port for charging compatible devices. Z-Bar Gen 4 maintains some beloved characteristics of its predecessors.
