Most Blackened 8w Tubes I Own

Most Blackened 8w Tubes I Own

The Eveready tubes seem to get the most end blackening most of the time. They were all from emergency lighting and didn't last very long. Does anyone know anything about the two "FT128W" tubes?

nice bit of end banding going on with some of them, I've got a Philips (Master) 8W T5 running non stop round the clock that has done 6 months and hasn't even got a mark. Looks like this one is in it for the long haul but I'll be PO'd if it doesn't give me a nice end band!

The FT128W is a CH Lighting white lamp, these were made sometime between 2008 and 2012. Chinese Sylvania are made at the same plant. They in fact have a reasonable track record for longevity apart from a poor few batches in 2013.

Bell lamps were halo 535 up to June 2013. From July 2013 to present date they are Halophosphate 835.
