The great chandeliers only used 30-50% of their light bulbs at any one time. If they were all on at once, one would go blind. For longevity reasons, the bulbs in the chandeliers were the same used in traffic lights. Each chandelier had hundreds of individually hanging glass. Iím glad we werenít located in an earth-quake prone state. Back in the old days, these chandeliers would actually turn slowly. For safety concerns, the motors were disconnected and are no longer used.
