Suffice it to say, the amount of ions emitted by a lamp varies in direct proportion to the exposed surface area of the salt lamp: the larger the surface area; the greater the output of negative ions. Negative ion output drops off dramatically within a few feet of the lamp regardless of its size and ion output. As a result, if it is ionization you are looking for, you may prefer to have more salt lamps placed throughout a room rather than one excessively large one.
