Large amounts of mercury in soviet F36T8

Large amounts of mercury in soviet F36T8

Click to view full size image

In the haul was included this soviet F36T8 tubes. I noticed the absolutely excessive ridiculous amounts of mercury inside. There is enough to cause some problems if broken. After documenting I double checked that it doesn't have any creepin' hairline cracks and stashed away in double sleeves to prevent accidental breakage. No etch, unknown manufacturer, but most probably SLZ.

Did you tried to run long enough to make Mercury into vapor state?

Pretty, please no more Chinese failure.

I tried for an hour, but it somehow never evaporated all the way, it seemed to reach equilibroum inside and few droplets were left in physical state.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

WOW! Never saw anything like this! The droplets are clinging to the inside just like a mercury vapor lamp.

May all the great lighting technologies have their place in history.
