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 Stick with gas. A far nicer quality of light. ;-) Tim If you look carefully in this screen shot you can see a gaslight they still have them here in Cambridge. Its down Barrow road which is a private road hence Google didn't go there. They are very dim at night but since the council upgraded our lights there're bloody useless too;!. https://goo.gl/maps/uzfcuP5RRjM2 -- Tony Sayer Gas is still in use in parts of London http://www.dailymail.co.uk/news/arti...ckens-day.html LED filament lamp for looks and pile of LEDs in a louvred compartment in the roof of the lantern for actual light. Thanks peeps for all the replies. I like the look of those gas mantles, maybe, rather than going for a large globe in there, i should aim to emulate the three gas mantles? So, now looking for three small but very bright bulbs that give out the same type of light as gas does... then i can group them together like in those lamps in that article. Cheers peeps, Steve |

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). When mercuries were more popular, so many places had either mercury or sodium, and I always wondered why someone didn't choose to install a mix. NT |

First it's not my definition. Second they're plainly obsolete by that defintion, not obsolescent. Obviously they are unusual and museum pieces. So many times I've been told 'the facts' by people who clearly haven't made any proper effort to find the facts out and don't have any clue what they are. NT |

Obviously they are unusual and museum pieces. In which case, your statement was either intentionally misleading or totally irrelevant to the matter under discussion. So many times I've been told 'the facts' by people who clearly haven't made any proper effort to find the facts out and don't have any clue what they are. Perhaps you are in the habit of providing them with misleading statements.. oookay |
