You can use these in your office for lighting effects. It’s a nice warm orange glow. There is much salt inside and the LED bulb does not get hot enough. There are holes on top of the salt light bulbs which pass the heat outside to keep the bulbs safe from burning. Looks cool though which is exactly what you as a nightlight. Built with E26/E27 medium base to fit the standard home lighting sockets, as well as any pendant light fixture ready to be used indoors or outdoors. You can use with or without lampshades or fixtures to bring vintage style into any lighting situation.
