GRDE Himalayan Salt Lamp

By the look of it, my impression is I would say something natural because of the Himalayan salt. I live in a small place with pets, something like this Himalayan Salt lamp is I need. It is an air purifier and description says it emits ions which helps purifies air.

It has a switch to turn this on and off. It's lampholder is adjustable,
With the bulb, I am not sure though if it should be the incandescent bulb or I can replace it with other kind of bulb like LED.

So far I love this kind of night lamp.

I got this at a discounted price or for free
