The Tilley FL10 was marketed for shafts and night fishing as well as constructional and mining work. Rated as 5000 candle power (reflected) it acts more like a spotlight than a flood light and I suspect would need to be suspended at 20 feet or more. This one has a tank from an IL33 and I expect not original. It could be that Tilley were using parts from other models but I tend to think its a replacement. I have an OL50 tank that I will probably put on this one and give it a cut and polish then. This great big juicy gem of a lamp weighs 19Lbs before fuel and will burn for 30 hours when filled up. The before shot And the working shots. When I manage to get it suspended at a reasonable height I'll add that shot too.
That FL10 looks very interesting ,looks like you need a very tall tree in your backyard to hang it . Bob .
She sure is a beauty. Not one we get to see often at all, in fact I think I’ve only seen a picture of one other. Some Ol50 lamps had the indoor tank with the three loops on top, Ive seen that numerous times, so I wouldn’t be surprised if it didn’t come from Tilley like that.
Thanks @Matthew92 , that was enough to convince me to leave this tank on it. Over the weekend I suspended it up in a tree at about 20 feet. Even hanging it at about 5 feet I could see it was more like a spot light than a floodlight but I was expecting more of a spread than this. The bright beam spread was only 6 feet. The sides and bottom of the picture below have been cropped to where there was light directly from the mantle but with no reflection from the reflector. That reached 40 feet but you wouldn't want to do any surgery or construction work in it. I hoisted up an OL50 as a comparison and it was far better for a work site than the FL10. I then lifted a Kayen AP2 and it was about as good or maybe slightly better than the FL10 if used as a work light. This design light may well have been good for night fishing but I don't know what else it would have been a good lamp for. I wonder if this is why they are so rare. The ones that were used for fishing would have rusted out in the salt very quickly.
@Anthony Good images showing the concentration of the beam. I wonder about the suitability for fishing with such a relatively narrow beam, hung over the side of a fishing boat, I would have thought that a broader spread of light would attract more fish. Perhaps as @Lamp_Doctor says, it may be better in a mine shaft. Henry.
