You cannot screw an E26 screw base into an E27 socket.
You would think that the smaller would screw into the larger but it is an issue of thread count and length.
In some cases you can bend the center contact in the lamp socket out and use the E26 in the E27 socket in base down operation.
Please turn of the electricity to the socket before adjusting the tab or you might have an exciting experience.

Mazda: On December 21, 1909, General Electric first used the name Mazda on their lamps.  The name was trademarked and assigned the number 77,779 by the United States Patent and Trademarke Office.  Today, we associate the name with automobiles, but when it was first used by GE it was chosen to represent the best that the American Lighting industry had to offer at the time, and it was selected due to the fact that Persian mythology gave the name Ahura Mazda to the god of light. General Electric dropped the Mazda trademark in 1945, and ceased licensing the name as well.
