Question: Does this lamp have a dimmable switch in which you can adjust the intensity of the light?
Document: The on/off switch is a basic roll type as opposed to the fancier dimmers on my other ones. None of this really matters as the glow the light produces and the negative ions released are the same as the more expensive lamps. And I got two lamps for one price. Can't beat that with a stick. And customer service can't be beat. One lamp had a defective socket. I emailed the company and has a reply before I got out of my email program.
The boxes were tore up. The packing was not done very well. Which caused the the wood on my lamp to be chipped. The the picture show the salt lamp to be the pretty peach color which the lamps ARE NOT. They are light pink with a lot of black spots on them. Wish I would have know before hand.
Great ambiance, amazing price for two lamps! The cords are not attached inside of the lamp, you simply place the salt rocks over the light bulbs. We put one in each room of our massage clinic and at the front reception desk and they add a very nice ambiance all around. Many compliments on them! They come with the bulbs and are not too bright but not too dark. Very nice amber glow.
Very nice products! For the money, it's a great deal! I bought two, thinking I could put one in my bedroom, but the light is just a bit too bright for my tastes - making it hard to sleep. I'll give the second one away as a gift.The one I am using is in my living room, and it looks great! I love sitting on the couch watching a movie with only the light from this lamp in the room (other than the TV).
they didn't come with light bulbs and i wish that they did so i didn't have to try and find bulbs that would fit
great price and will light up the room. For softer glow  use an amber bulb. Very nice and happy with product.
We love them! They are much larger than we expected and a also great night light. We are planning on ordering more for work and other family members.
I purchased this two pack -- one is perfect but the other arrived cracked in half so only one half of it lights up, the other half looks like a rock, I guess the separation isn't allowing the light through. Sad! :(
Beautiful lamps. They arrived so quickly, they are both unique and have a gorgeous light and color to them. I have seen these lamps in many places and they would be very expensive in other stores. This is an awesome deal and I'm so excited to not only be able to afford them but they are gorgeous as well
To all that look at this product I have asthma and allergies really bad. The only thing I have notice by using this product is that the amber light relaxes you. The light is calming but for the health benefits I have not noticed any as of yet not even with my bad sinus issues which is why I purchased the product.
Answer: yes
