forgot to say these came off eol atlas 85w 8ft tubes warm white from the 70s they were all dead unfortunately

Davy aka versalift i seem to remember you have an alpha 5 with non original lampholders you are welcome to some of these i don't need 8!

thats odd, i found a pair of these years back with an old thorn 8 foot 85 watt tube still in them, it was resting on a steel roof support in a factory building high up, they were son lowbays in there for lighting, but once they must have had 8 foot 85 watt tubes lighting the shed up, what fitting was this out of then?

not sure what fitting they were in they were just on the dead tubes in the recycling box
