I recently received the gray (medium) salt lamp as a gift. The 15 watt bulb that it comes with isn’t very bright and doesn’t shine through the rock very well (even when turned all the way up). Can I go purchase any higher watt bulb for it or does it have to be a certain kind of bulb?
I am so sorry to hear this. In most cases, the Caviar grey lamp works pretty well with a 15 watt bulbs. However, since these are natural rocks, some of the lamps are a little bigger than others which sometimes can make it difficult for light to cross. This is an easy fix. Please try a 25 W bulb. This should allow there to be more light. The bulb you are looking for is an E12 bulb. If you have trouble finding them, I can send you some online sources for finding them.
