Re: Anglepoise bulbs
Those LED filament bulbs are also available in 'pearl' or 'frosted' form.
These are the types I use in 'non-vintage' applications, being indistinguishable from normal filament lamps. |

Re: Anglepoise bulbs
Why? Excessive heat output? Probability of reduced bulb life due to the shade reducing dissipation of the heat from that bulb? Excessive light output?
Whatever, I've been using 100-W. incandescent bulbs in four Anglepoise lamps here for many years: no problems at all - just need to remember not to touch the shade! Al. |

Re: Anglepoise bulbs
I found that the original Bakelite lampholder of mine deteriorated due to the heat of a 100W bulb. I replaced it with a brass lampholder holder, which did require adjusting the springs to compensate for the extra weight. I now use 40W or 60W reflector lamps, of which I laid in a stock when they were still available.

Re: Anglepoise bulbs
I’m currently using a 60w bulb, last one, so I will be getting a “modern” led, I will ensure the output is at least 800 Lumins preferable 1000 +.

Re: Anglepoise bulbs
Re: post 43: fitment of a brass lamp-holder as a replacement. Your findings and solution are same as mine.

Re: Anglepoise bulbs
I was considering using my brass holder with ceramic insert, but then I wondered about safety and the fact that there is no earth lead going to lamp. This lamp and all my stuff will pass to my grandchildren.
I tried and failed to run an earth lead up inside lamp so decided to fit plastic holder instead. Mine is very old and I wonder do the slightly younger versions have an earth lead fitted? Cheers John |

Re: Anglepoise bulbs
The earth is separated before the other two wires go into the hollow arm, and terminates on the spring anchorage.

Re: Anglepoise bulbs
Mine is fitted with a flat 2 core lead, I presume it’s original. Interestingly there is the “double square sign” inside the lamp holder, which today as I understand it means it’s double insulated, but can that be, this lamp is very old, when did the double insulated sign first appear?

Later lamps (clones?) with metal shades wouldn't have been fried by a 100W bulb, but would still have got very hot! Nowadays, mechanical considerations apart, you could use as bright a low energy bulb as you liked.

Re: Anglepoise bulbs
My Anglepoise lamp has a metal shade and the name on the side near the heavy base, I’m presuming it to be original.
I’ve just purchased an led bc bulb (100w equivalent) from Tesco for about £7, the output is 1000 lumins and I have just fitted it, the illumination is excellent, perfect for my bench work. The only observation is the length of bulb, 2 to 3 cm longer, but I have no problem with that. Cheers John |

Re: Anglepoise bulbs
The post from AC:HL is very informative, thank you. As far as I can see no mention of the material the shade is made of, pity, as I didn’t know some were made of Bakelite either, but that is the good thing about this forum, I learn something every day.
Cheers John |

Re: Anglepoise bulbs
Well, it might not have been actual bakelite, but it was a hard black plastic of some sort and definitely smelled a bit when it got hot!

Re: Anglepoise bulbs
I have known certain types /makes of 'plastic' bayonet cap bulb holders to produce the most awful smell if they are substantially overheated . . . often caused by the (erroneous) fitment of an incandescent bulb of 100-W or above.
ISTR that that smell to be somewhat reminiscent of rotting fish Once smelt ... never forgotten! Al. |

Re: Anglepoise bulbs
It would seem that Bakelite was used for a while due to post war aluminium shortages.

Re: Anglepoise bulbs
I can remember finding a broken plastic light shade that stank of fish when it was chucked onto a bonfire. It was a sort of cream colour.

Re: Anglepoise bulbs
I certainly remember the fish smell.
Many years ago the building manger of the very large workshop facility that I had just joined was convinced that a dead rodent had died in the air con, and was just about to call in the environmental team to look for it, however it turned out to be a double 13amp socket “cooking”, we all had a bit of a laugh over that.

Re: Anglepoise bulbs
I was thinking that metal shortages might have meant a switch to bakelite.

Re: Anglepoise bulbs
About 20 years ago a couple of our circa 20 year old lamp holders got the stinking fish syndrome, cured by fitting new skirts. A label on the lampholder of the MK pendant set I bought a few days ago says it is rated for lamps of up to 150W.
