Its a shame, I thought the first was just unlucky, but when the second one started to go at exactly the same time, you can pretty much guess what the whole box will do! Neutral

Isn't this problem something to do with the starting resistors or type of starting resistors they used in the osrams making contact with the ir coat and reacting with it?
AngryHorse   [14 Aug, 2015 at 10:49 PM]
These are initially a Philips lamp, made on Philips machinery as you say, so why would the make their own lamps poor, and print Osram on them?, or do you mean force people to buy the masters?

How many of these went black from this batch again?
thorncollector   [16 Sep, 2015 at 08:46 PM]
whats the batch code on these eg n8b8? it happens with philips 18w sox-e aswell the blackening i seen one the other day date code 1d manufactured april 2011

If this is happening in the same fitting have you checked the ballast is not over running the lamp? i used to have a twin 26W CFL downlight in my bathroom with magnetic gear and 1 lamp i never changed the other would only last a few months with domestic use.

Mine started going black too im starting to wonder if its the fittings with built in ignitors that are causing it
FrontSideBus   [21 Feb, 2017 at 07:15 PM]
I'm using an SRS type ballast in my G6 and the lamp seems ok so far?
lampy   [14 Feb, 2018 at 08:20 PM]
i think its somehting to do with 18 watt sox in general, they were all a bit shit to be honest, even the old ones
AngryHorse   [14 Feb, 2018 at 08:25 PM]
Yeah, the black one bottom right was the 3rd from this batch to do it within 2 years, this is why I stopped using SOX for outside.
Danny   [14 Feb, 2018 at 09:11 PM]
Have you got many of these left? Id be interested in trying one of these in a fitting without an ignitor to see if they go black
AngryHorse   [14 Feb, 2018 at 09:13 PM]
9 of, I think.....?
Danny   [14 Feb, 2018 at 09:18 PM]
I still think it’s fittings with ignitors as well as the starting probe in the lamp causing this
AngryHorse   [14 Feb, 2018 at 09:27 PM]
But it never happened with GEC, Shaw lamps?????, only these Philips/Osram ones
Danny   [14 Feb, 2018 at 09:29 PM]
Kev has a shaw going black now in his NGX on the barn
AngryHorse   [14 Feb, 2018 at 09:34 PM]
The plot thickens....... Shocked , and funny enough, my dads XGC turned every Shaw lamp black, but hasn`t yet done it to these?????
Danny   [14 Feb, 2018 at 09:39 PM]
This is why I think ignitors are the issue. The lamp in my XWC at the moment is the last I’ll be using in 18w SOX unless I can come across more lamps before it dies. I wonder if the ignitor in my XWC as well as the starting probe had anything to do with the early failure of my 18w GE
AngryHorse   [14 Feb, 2018 at 09:47 PM]
Was the GE a late one?, I had both a 35 and 55 GE, but made just before Leicestershire closed down, and BOTH went black!, I`m wondering if they were the last, "can`t be arsed" made lamps?
Danny   [14 Feb, 2018 at 10:05 PM]
This one is September 1996 according to the date sheet?
Danny   [14 Feb, 2018 at 11:49 PM]
I’m actually wondering weather to pull it down and stick a 70w SON bulkhead up there
