THIS CLEAR GLASS ROUND GLOBE CAN BE USED IN A HANGING LIGHT FIXTURE OR A TABLE TOP LAMP THAT YOU CAN FILL WITH MARBLES, COLORED BEADS, GAME PIECES, ETC.  IF YOU USE IT AS A HANGING LIGHT FIXTURE I BELIEVE YOU WOULD WANT TO PUT SOMETHING IN THE INSIDE SO IT IS NOT SO BRIGHT IN THE ROOM.  A DIFFUSER....

I DO NOT KNOW HOW ROUND IT IS BUT IT MEASURES 7 3/4 INCHES TALL. 

THE LARGER OPENING MEASURES 4 INCHES IN DIAMETER FROM ONE SIDE TO THE OTHER...WITH THE INSIDE OPENING MEASURING 3 5/8 INCHES.  THERE IS A LIP ON THIS SIDE WHICH MEASURES 9/16 INCHES.  THERE IS A TEENY TINY FLEA BITE ON THE TOP OF THE LIP.  THIS WILL BE COVERED UP WITH WHATEVER COVER PLATE OR BRACKET.  

 

THE SMALLER OPENING MEASURES 3 1/16 INCHES IN DIAMETER FROM ONE SIDE TO THE OTHER...WITH THE INSIDE OPENING MEASURING 2 1/2 INCHES.  THERE IS NO LIP ON THIS SIDE.
