The Palace Theater Light was once thought to be the longest-running light bulb in the world. [5] [3] It appeared in the 1970 edition of the Guinness Book of World Records before it was replaced by the Centennial Light two years later when it was discovered to be older. [6] [1] The Palace Theater Light is now recognized as the second longest ...

This, along with the long-life light-emitting diode which does not burn out like an incandescent bulb, give the flashlight a long lifetime, making it a useful emergency light. A disadvantage of many current models is that the supercapacitor cannot store much energy in comparison to a lithium-ion cell, limiting the operating time per charge.

The original twinkle bulbs were C7½ and some C9¼ incandescent light bulbs with a bimetallic strip. Once the bulb warms up, the strip pulls slightly away from the contact, opening and interrupting the parallel circuit through the bulb and turning it off. The bulb then cools, allowing the strip to bend back and make contact again.
The bulb's "turn on" voltage V b is higher than its "turn off" voltage V e. This property, called hysteresis , allows the bulb to function as an oscillator. Hysteresis is due to the bulb's negative resistance , the fall in voltage with increasing current after breakdown, [ 7 ] [ 14 ] which is a property of all gas-discharge lamps .
