Update: this bulb has finally gone EOL and it did trip the circuit breaker we shall flip the breaker back on tomorrow but I went to see this bulb and I saw a filament piece lying on the bottom

This bulb has served ~2 years of lighting my computer room

Ok Robert how's 2 years of service life for a fairly modern incandescent bulb like this one

I'm quite sad to see this bulb go EOL it was the brightest one in my house and its size is larger than a 100W incandescent GLS

Oh well I've got a 4 pack of 100W GLS bulbs which I don't mind using them up (the green package with bulbs made from "illuminations" ) they be a bit dimmer compared to 150W but still do a decent amount of light output

Flurofan, do that shop have any more of these? If so I would snaffle a few of them (maybe 5 or so) even if you get a Chinese made one it is better than no examples of 150w GLS lamps. I can see a quality difference between my timothy whites 150w bulb and my 150w and 200w eveready lamps, also the envelope on the timothy whites s bigger.
anyway when I found all those GLS lamps at that military stall last year I now have some Chinese and some UK lamps in the collection, some were brand new (I forgot to upload all of the others, as I made packaging sleves for them out of corrugated card board

btw I have a 3pk of 40w R50 bulbs by illuminations, from aldi - they were reduced to I think 78p so I thought I would save them, if not they would only end up in the trash

I don't know and I need to find time to visit that shop, hopefully around Feb half term. Anyhow I've got a 4 pack of illumination 100W GLS bulbs which I can use be good to use them up (I shall try to save 1 of them)

Anyhow I've safely stored my EOL 150W OSRAM in my newly organised boxes of lamps

Update: Well after 2.5 years of having my computer room lit by 150W incandescent, the socket has degraded meaning that the BC holder can no longer support the bulb nor light it up, as a result I'm going back to fluorescent and will reveal the fixture when it arrives/gets installed

Part of the plastic in the BC holder snapped

The FL luminaire is going to be a 58W T8 with switchstart gear (hopefully)

Can you get something more heat resistant (as a socket for direct ceiling installation, not as ceramic socket which is component for luminaires) ?

58W T8 is very bright. I would of installed a linear, and i have several nice ones made in the 90s, but i am not a "need lot of light" sort of guy

Not too sure about that, Ash

For the fixture I ordered, I can separately order a diffuser specially for the model in both prismatic and opal, think I am going to go with the opal

Goodness me it has been 4 years since I bought this OSRAM Slovakian made 150W GLS from this electrical shop in Reading which is now facing closure on 15th December. Well actually the shop from 2015 (when the OSRAM EOL'ed) to now they were only stocking Crompton ones which were actually very good as the Crompton one lasted like 2 years

Have you got a photo of the FL fixture that replaced the B22 socket?

That's a cool bulb, Peter! I've always liked incandescents the best and I'm glad to hear you got a lot of use out of this one. I haven't seen them here in the USA, but I know there are some halogen versions of 150 watt incandescents that use 105 watts. Those might be easier to find if you're looking for something bright enough to replace this original 150 watt Osram

Philips DuraMax and GE Miser forever!  Classic incandescents are the best incandescents!

Beta 5: Not yet there is still the B22 socket in my computer room but a temporary one as we need to change the wiring of the ceiling lighting system, you have seen it with the Philips SL-E Pro and atm the Crompton Crompack 58W FL fixture is still in the loft and I'd say the project is so behind schedule

CEB93 There are some 150W eqwivent ones too but I am not going to bother with them as the original 150W incandescents are much better in terms of envelope size

Yeah, you lose the classic large size of the 150 watt incandescent in the new halogen energy efficient versions. It's surprising how small the outer envelope is in some halogens, especially those Philips 150 watt BT15s that we both have.
