I forgot to post this, but just bought a GE Ecolux Cool White F20T12 a couple days ago. *Might* be purchasing a GE Halophosphate 3500k F20T12, but more
than likely may skip out on that purchase. There's a good chance I may use that Ecolux and one of my F20T12's from Philips, for my light tables instead...
and then I'll use my Sylvania GTE and the other F20T12 as replacements. Maybe. lol
Really interested to see how that GTE performs with the cold temp Trigger Start ballast though.
Today I did an inspection on all of my living room F30T12's... checked all the ends for any additional end blackening. All ends have a slight bit of
fair-weather end blackening, but I've noticed that one of my Sylvania Supersavers has a slight bit of "spot" end blackening developing... very normal
of Sylvania lamps to do this after a good amount of use has been put into them. One of my Sylvania F30T12's in my loft, is also doing this as well,
on the etch side. At this point though both situations are very slight... not dense.
My lone Sylvania Cool White F15T12 also has a very slight bit of end blackening occurring as well. I still have yet to post that lamp on Lighting Gallery.
I live in the countryside… there aren’t many big vans or lorries around and the nearest quarry is near Steyning, several miles away, and I’m not sure if it’s as active as it used to be. My only guess is an earthquake, but I did feel a bit light headed after so, maybe it was just lack of Something or other.
