US made 36w 4 foot T8 lamps in colour 840.

Generally USA made tubes are on par with tubes made in Europe. These should be good ones!

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

I am always fascinated on how smooth the glass is on these american tubes.. Like, for real. It is so smooth that when you rub two tubes against each other there is no resistance, it just glides. Try rubbing two tungsram tubes, your ears will bleed

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 ;

Interesting... these USA made GE Polylux T8s are performing very differently by the way you use it.
They never go mercury-starved when installed on our buses, but if you run them 24*7, they won’t last too long before going mercury-starved.

No more cheapy crappy Chinese junk, please.
