We use Osram lamps and we get at least 1 fail per box. The annoying thing is that if you replace a tube that is out and the replacement doesnt work, you assume the fitting and we call the electrician in.
We are wiser now....
We have had better luck with the GE Polylux XL but maintenance cant get them for some reason.
I took my time, I hurried up, The choice was mine, I didn't think enough
