[time-nuts] Rb lamp lifetime...

Yuri,

as a rule of thumb, read my message posted here last month:

I have 10 EFRATOM LPRO, and only one came with a faulty lamp.
I think it lost vacuum, and the glass looks clear but with
small white pigments. I inspected some of the other lamps,
and the glass looks more or less brownish.
No other tests made on the lamps.
