In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models , which need separate voltages to power the motor and the RC equipment.
1A7GT/DK32 – Pentagrid converter, re-engineered version of types 1A6 and 1D7-G, designed for use in portable AC/DC/Dry-cell battery radios introduced in 1938. Has 1.4 V/50 mA filament. 1B7-GT – Re-engineered version of types 1C6 and 1C7-G, designed for use in dry-cell battery radios with shortwave bands. Has 1.4 V/100 mA filament
The Delta Electric Company was an American electronics manufacturer formed in 1913 in Marion, Indiana [1] that produced lanterns, flashlights, automotive and bicycle lighting, battery tubes, horns, horn buttons, light switches, other battery-powered electrical parts, [2] and bilge pumps. [3]
R. E. Dietz Co., Ltd. (formerly R. E. Dietz Company) is a lighting products manufacturer best known for its hot blast and cold blast kerosene lanterns. The company was founded in 1840 when its founder, 22-year-old Robert Edwin Dietz , purchased a lamp and oil business in Brooklyn , New York .
Lantern batteries are physically larger and consequently offer higher capacity than the more common flashlight batteries. Lantern batteries comprise multiple cells inside a housing. The most common variant in the US is the 6-volt square-base battery with spring terminals. In Europe the most common one is the 4.5-volt flat pack.

A diagram of a Selecon Performance Lighting Pacific Zoomspot. The truncated conical ellipse allows better focusing abilities for the light. If the bulb is placed in the first focus, then all light will pass through the second focus at the same time. This creates a very bright beam of light. [1] ERS or profile lanterns have many useful features.
When the lamp sustains the arc, the ballast performs its second function, to limit the current to that needed to operate the lamp. The lamp, ballast, and igniter are rating-matched to each other; these parts must be replaced with the same rating as the failed component or the lamp will not work.
