Congratulations! You’ve decided to decorate your home or outdoor living space with gas lighting. One of the first steps in customizing your gas fixture is to determine whether your lamps will be illuminated by gas mantle burners or open flame burners. But what’s the difference?
About Gas Mantle Lamps
Traditional gas mantle lighting uses incandescent gas mantles, or Welsbach mantles, to generate a bright, solid white light when heated by gas flame. When lit, gas mantles yield a soft, romantic light and can be used in place of electric light bulbs. The primary purpose of gas mantles is to provide light when gas is preferred, or electric is not available, to fuel exterior lights.
Gas mantle burners are available in single, dual, triple, or quad configuration, depending on the model lamp they are being housed in. When lit, each gas mantle is equivalent to approximately 50 watts of incandescent light. Therefore, a single mantle burner will provide ~50 watts of incandescent light; a dual ~100 watts of incandescent light; a triple ~150 watts of incandescent light; and a quad ~200 watts of incandescent light. Gas mantles are durable but become very fragile once lit, so they are intended to remain on and undisturbed 24 hours per day.
About Open Flame Gas Lamps
Conversely, open flame gas lighting infuses outdoor settings with the warm, flickering light of an open flame. Imagine a soft candle burning inside a gas lamp fixture. Rather than providing a solid, steady light, the primary purpose of open flame burners is to provide dramatic ambiance to entrances, walkways, gardens, and entertainment spaces. While the light emitted from open flames is not as bright as gas mantles, they provide unique character and historical charm to almost any outdoor setting.
Open flame burners are available in two different configurations: Straight Flame and Maple Leaf Flame. A Straight Flame simply generates a single, vertical stream of fire, while a Maple Leaf Flame fans out into the shape of a maple leaf, displaying three distinct points. The size and shape of each flame can be somewhat controlled by adjusting the gas valve of the lamp, located in the collar of each fixture, directly below the lantern. While open flame burners are also intended to remain on 24 hours per day, they can be turned off and manually relit by applying direct flame to the burner tip inside the fixture.
AGLW gas mantle burners may be fueled by Natural Gas or Liquid Propane, while open flame burners may only be fueled by Natural Gas. The BTUs of gas mantle burners range from 2,200–4,400, depending on the configuration selected, while the BTUs of open flame burners range from 2,800–3,100.
