Sylvania YELLOW K shape lamps

Sylvania YELLOW K shape lamps

Here are 2 example, one is at a different angle!

They have the smaller than usual size to an ordinary 40W K shape lamp, especially my KNIGHT branded (THORN made) one

Due to the use of krypton they would not be suitable for outdoor festoon lighting as the filler gas conducts the heat more effectively than argon and therefore if any cold water/rain fell on it, it would shatter! I would NOT suspect a 2000hr long life vacuum lamp would exist if at all possible as we know that the filament evaporates/thins out very fast, hence the blackening
