Replogle Globes is a globe manufacturer that creates globes with highly contrasting colours, as well as muted colours for an "Old World" look in school and office settings. However, the illuminated globes' light bulbs sometimes burn out. You can purchase replacement bulbs at local hardware stores, though Replogle Globes warns that using more than a 75-watt bulb for its 32-inch globe could damage your product. A 12-inch globe should use only a 25-watt bulb, and a 20-inch globe should use only a 40-watt bulb.
Remove globe from electrical power and turn it upside down with the base of the globe sticking in the air. Use a screwdriver to remove the screw located in the metal numbered semi-meridian at the base. Remove the semi-meridian, along with the semi-meridian's time dial, which is a separate piece located at the North Pole end of the globe.
Pull the electrical plate out from the base of the globe. The bulb is attached to the electrical plate. Turn the bulb counterclockwise to loosen and then remove it. Use a 25-watt replacement bulb and screw it clockwise to secure it to the electrical plate.
Insert the electrical plate back into the base of the globe. Place time dial atop the semi-meridian again. Place the semi-meridian back on the globe, ensuring that it is lined up with the proper holes. Screw it back into place.
Unplug the globe from the electrical socket and take the globe from its stand. Do not remove the meridian ring encircling the globe. Set the globe on a pillow. The globe should be facing upward so that the North Pole end is closest to you. Use a screwdriver to remove the two screws holding the bracket in place on top of the globe.
Set the globe on its side so that the North Pole and South Pole are resting horizontally. Sit near the South Pole end of the globe and hold onto both sides of the meridian ring, positioning both hands at the equator. Gently lift the ring up and pull it off. This removes the South Pole electrical assembly.
Use a 40-watt bulb for a 20-globe or a 75-watt bulb for a 32-globe as a replacement. Unscrew the old bulb by turning it counterclockwise, and insert the new bulb by screwing it in place clockwise.
Put the meridian ring back into place, inserting the electrical assembly back into the South Pole. Use a screwdriver to reinsert the two screws to secure the bracket on top of the globe. Place the globe back on its stand.
Do not attempt to modify the globe's electrical plug. Contact a professional electrician if you are having problems with your globe.
