...Could very well be 2005, I wasn't sure these style of tubes went back that far though. I guess Lee would know.
Source ? Date ?
"Not sure If they’re msde to osrams spec. Something james hooker may know though?"
Many years ago, when Halophosphate ("Basic") lamps were made in Germany, they were rated 13000h and lasted 3 times that, while Lumilux were rated 20000h
Nowadays, the "Basic" from China are rated 13000h and last exactly 13000h
Also the "Basic" 36W have up to 9mg Mercury where the Lumilux is 2.5 or so. (as they dont have to pass any "low mercury" standard, they put a lot there with less precise control)
So... Osram spec they are, but knowingly a lower spec
Also, the Osram China tubes i know are the oens made in Osram's "f" factory. They used to have Germany-like endcaps and now have Philips-like, one big isolator insert. I have come to have very low expectations from the Chinese tubes with the 2 small isolator circles around the pins
"Them smart lux are the osrams that I think will be made to German osram spec not these."
Smartlux are cheaper Lumilux. Officially according to Osram, they differ from the Lumilux in worse Lm deprecation through the lamp life
