CH lighting F10T8/D 10w dinky tubes running on a Harvard DKE 13 (7-13w D/D/DD/T5) UK made elctronic ballast (each has their own ballast) The other tube died without me knowing,hence one new one & one banded like a bitch. Wattage drawn for a single tube is 9. something watts

The banded one is lovely

yeah, it took a while, I think they are a little under run.. shame I missed the one that died..

Yeah 10W T8's run at 46V 230mA so depending on the exact specifics of the HF ballast may be a little under-run on a 13W PL HF ballast some nice banding tho, how did the other one die, did it also band up, then sock up or did it die in another way? how many hours do they run? is it 247 or are there some switching cycles involved? Smile

im guessing this was once of those cheap battery emergency lights with the sealed lead acid battery in that eats tubes? (edit: just seen your other upload on these tubes that the fixture was just that !)

they were ran 24-7, the other one banded up. when it died, both ends socked & cathodes both open circuit so guess it went out well..
