Hello all, I got this BT26 awhile ago, I just had to save some money for a gas regulator, which I must say works extremely well, I used a old Coleman gas mantle that I had for years now, while I am waiting for some to arrive from the UK. I know this isn't a pressure lamp, but I thought someone might be interested in seeing it work, so here is the money shot, enjoy. I do love it, even though its gas, and of course its a Tilley, so I just had to have it in my collection.
... Interesting... it must have been made in the '50's then, if it has 'Made in Hendon?' I can just make out one of the air holes in the hood, so am presuming that it used the same hood as an X246 series?.. Perhaps the cage as well?? Good for you for saving and resurrecting
Well it must be, otherwise how does the gas get from the cylinder to the lamp, if not by a pressure differential? Not only is it 'pressure', it's definitely a 'lamp' and by virtue of its age and rarity, 'classic'. So in my book, that's a classic pressure lamp and deserves two thumbs-up - no question. Well done on getting it going - I've three of them and they all steadfastly refuse to burn correctly, no matter what mantle I put on them. The correct mantle is a Tilley 1646. Anyway, I suspect 'operator error' - probably I'm using the wrong gas / regulator or whatever...
@Buggerlugs A good find and running nicely. It would be good to see some detailed photos in the reference gallery.
A lucky find and I have posted the paperwork for Tilley gas lamps here before, but I do not recall where, they made a range of gas products. These links show some of those products, but it's not the pages which I posted. https://classicpressurelamps.com/threads/tilley-catalogue-1969.11219/ https://classicpressurelamps.com/threads/1960s-bt25-and-bt25g.4779/

Hello. To my knowledge, gas lamps should always use a high pressure regulator. It could look like Buggerlug's lamp is off with a clear white light. The picture can of course be misleading I am attaching a picture of a gas lamp that I have. Tom
Looks like all the LPG Tilleys are 14lb/psi. All I have documents for anyway. When you say `high pressure`, how high are you thinking ??
Hello. In Denmark we have 2 types of regulators. High pressure regulator and low pressure regulator. The high pressure regulator emits between 2 and 4 kg of gas per hour, depending on how much is turned on the rotary valve. A low-pressure regulator emits the equivalent of 30 mbar. Whether it is different in other countries I do not know. So be careful when using gas. Tom
Thanks for your quick reply Tom. 30 mbar = 0.435113 Pound force per square inch so 14psi would = 965.266 mbar. 30 mbar is very low pressure indeed.
@Anthony The only thing high pressure is used in Danish homes is weed burners, and in the past gas lanterns. In industry, high pressure is used more often. Tom
@Anthony, I have an adjustable regulator, which on the advice from malcolm race, he told me to use 1bar, which is about 14.5psi. My photo doesn't do my lamp justice, its actually a white light and is very bright, next time I will take a photo at night, to show it's full potential. Here are some photos of the regulator. Sorry that's all I have as I throw the packaging away, I hope that helps you.
Except model GH59 Overhead hanging lamp which, according to https://classicpressurelamps.com/threads/tilley-lp-gas-appliances.17291/ "is made to operate on domestic pressure of 11 inches water gauge" = 0.39700309798288286 P.S.I. Inch of water - Wikipedia Convert millibar to psi - Conversion of Measurement Units
On the spec label on the back of Bullfinch propane/butane lamps they equate 1 Bar to 15 psi. I guess it's not that critical. 1 Atmosphere it is then
In my area, there are also two basic types(high and low) of lpg regulators. I'm referring to the so-called 'domestic' varieties mostly for gas-fueled stoves for cooking, etc. The 'low' ones are preset and non-adjustable(mostly for homes). The 'high' ones are adjustable to a max of about 2bar(~30psi), mostly used for stoves in restaurants and other similar commercial purposes. I'm not referring to any of the regulators used for industrial gasses(acetylene, oxygen, etc). These are strictly for non-domestic applications.
@Tom Pedersen Yeah. I'd think its almost similar anywhere else for naturally aspirated gas burners and such items. The fuel would be pressurized to about 2 bar/30psi. That's about the norminal range where most liquid-fueled lanterns would be operating at. Quite a number of years back, I've actually constructed a Frankie from a kerosene-fueled Petromax clone and converted it into an instant-lighting lpg-fueled lamp. It had a piezo-electric ignitor and a pilot flame directed to the mantle and burner. It would light up almost instantly without flaring with a turn of the knob. As convenient to light as a domestic gas stove in the kitchen. I've even tested it with MAPP gas for a hotter flame to obtain an even whiter glow from the mantle . I've since torn it apart and discarded most parts of it due to heavy rusting from years of neglect.
In the UK, there are three main types of LPG pressure regulator. A fixed low pressure regulator, often used for heaters and cookers. A fixed high pressure regulator, 1 bar. Often used for lights. An adjustable high pressure regulator that can be set for any pressure up to 2 bar. Used for industrial equipment. The first two types are made for butane or propane. The adjustable high pressure regulator is for propane only. Not applicable to butane as in cool weather the pressure in the cylinder wont reach 2 bar. The fixed 1 bar regulators for butane need the cylinder to be in warm conditions, in cold weather they dont work.
