Large light bulb for very old street lamp
Hi peeps,
I have an old Victorian street lamp i want to hang off a telegraph pole in my garden. It was gas originally, but i need it to produce a decent amount of light, be efficient and reliable. It looks a bit like this- http://www.englishlampposts.co.uk/me...t_Lanterns.JPG But is 50cm wide and 80cm tall, i think it needs a bigger bulb! Any suggestions? Ta Steve |

High pressure mercury vapour lamps were a common replacement in street lighting gas lanterns. but are now obsolete, with sodium & HID both giving better lpw and better light quality. HID would be good if you need an excess of light. NT |

I cannot see it, but around our way when I came here in1957, the lights were
like ordinary bulbs with a kind of reflector of pieces of mirror that aimed the light downwards. I always though back then that the bulbs looked rather small. So it could be its just the way it is or was.

Ta Steve Back in 1988, I was part of a team working on a project outside Shanghai. The whole hotel was supplied with 40W bulbs, which flashed at somewhere between a half and one Hz. One of my compatriots, John, had less than perfect eyesight, and one weekend, I found the large shop in downtown Shanghai which sold all sorts of lovely electrical goodies, many of which would have looked good in a museum here, but it did have 5.25 inch diskettes. In this place, I found a 150W bulb, it was huge, at least 8 inches long, if not more, and I carefully carried it home on the bus, and presented it to John at the communal dinner table, to his great joy. From that day on, it was easy to see which room was his, the window was lit up "Like the Trocadero". -- Davey. |

Ta Steve I'm not sure a large bulb will look right. AFAIR small gas street lamps had a single mantle. The larger lamps did not use a larger mantle, but multiple small ones. A modern (German) example can be seen he https://en.wikipedia.org/wiki/File:G...n_Rathenow.jpg But I doubt that it would be a simple matter to convert your lamp to multiple bulbs. -- Jeff |

Ah, wasn't firing on all cylinders last night. Day 3 of a cold and lungs further irritated by the dust from stacking 800 kg of logs. Looked at the similar style street lights in twon this evening. They have a panel at ceiling level below the roof and the fitting is attached to that with a ridged upturned bowl as difuser around the bulb which I think is HP sodium. That is they are orange but not the monochromatic orange of LP sodium. Don't look to bad.

If you wander round when is now known as the "adventure island" theme park in Southend at night, its got loads of discharge lighting - in any run of lamps they quite often alternate high pressure sodium with mercury... So you get the yellow / pinky cast from the sodium, and a slight blue / purple tinge from the mercury. The effect is actually quite pleasing (far more so than either technology on its own would be). -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Apparently the place was "forgotten" when the rest of the town was converted and the gas lamps remained untouched for so long they are now listed and must stay. Its not as if the borough would have had trouble getting electric to the place years ago, despite its rural looks even back in the 30's enough people lived there that it was worth running the Trolley Bus wires to it. https://goo.gl/maps/TdqDZ8ZHXPC2 G.Harman |
