"Fact Sheet"

A natural gas dual mantle Gaslight consumes:

2.1 cu ft. per hr (2125 BTU'S) x 24 hrs per day x 30 days per month=
1512 cu ft.=per month x .0054 ccf (Est)=
$8.16 per month x 12 mos.=
$97.92 annual revenue. (estimated)

Gaslight output in Lumens:

100 Watts=1360 Lumens
1 Mantle=50 Watt bulb
680 Lumens per mantle

Gaslight output in F.C. (Foot Candle)

Dual Mantle Light 10 Foot High and 25' out, 3 foot high emits approximately .03 F.C.
Triple Mantle Light 10 Foot High and at 25' out, 3 foot high emits approximately .04 F.C.
Quad Mantle Light 10 Foot High and at 25' out, 3 foot high emits approximately .06 F.C.

*Because open flame lights vary so much in design and there are no industry standard it is difficult to be precise about their specifications. Some open flame lights have no orifice and all of them "flicker". Both of these facts make it difficult if not impossible to gauge their consumption or light output.
