Printed Lamp Shades
The fitting rings on your custom lamp shades fit standard light fittings. When installing a bulb into the lampshade, make sure the light switch is turned off so you don't burn your hand.
For the smaller custom made lamp shades (7.87" round and oval) the maximum wattage is 40w bulb. For the other sizes, it's safe to use 60w-100w bulbs but energy saving bulbs are better for the environment.
Your printed lamp shades don't come with a bulb included, as it could easily be smashed during the delivery process and cause potential danger to the person who opens the package.
