The salt used in the lamps is the real deal mined in the Himalayan mountains. When the salt is heated, it releases a vapor and "sweats", causing it to break down and get messy. ZenCube uses an LED bulb to heat the salt to a just-right temperature. It still produces that negative ion-packed vapor (thought to neutralize free radicals, revitalize cell metabolism, and enhance the immune system), but doesn’t break down the salt. There’s an app-enabled lamp that lets you switch up the light color, too. Now you can harness that mood-and health-boosting goodness in an attractive and longer lasting salt lamp.
