Comes with power cord a light level switch included as well as the salt lamp light bulb.
In the flats next door, before they were evicted, were a noisy couple. Perhaps in order to soothe the other's soul, a salt lamp was bought ( not from us) but it did not get to be used as this landed on our roof with a loud thud. Still worked though, and the thrower could be roped into our next Olympics?
But yes, the colour may be intended to soothe a troubled locked down person or two. You need to put the bulb in and power it up though.
