My new Eccles protector lamp SL came in the post today! all i have to do now is work out how to use it...

From what i already understand of these lamps:
These lamps were often used to detect and warn of gasses in mines. The miners were not allowed to re-light the lamps underground, so variations of the lamp were made, such as the SL for Side lit. These were used in conjunction with the re-lighter lamps.
"The SL was lit by a low voltage electric current in the lamp room.
the principle of the davy gauze is that the flame will burn inside the gauze but the size of the mild steel gauze ie; 28swg wire with 28 holes per inch sufficiently dissipates the heat so as not to ignite methane or firedamp outside the gauze. so when methane is present it burns in a flame on top of the lamp flame and the height gives the percentage of methane present and thus warns of an explosive atmosphere.
re lighting underground if you relight a lamp in an explosive atmosphere it will detonate and cause an explosion."
A you-tube clip that have found, showing the lighting of a protector SL lamp:
