Homemade fluorescent tube
This is a proper fluorescent with fillaments. I scavenged the ends from a existing broken tube and put some radar red cold cathode tube between them. By some miracle this one isnt badly contaminated. Mainly because I heated the fillaments to yellow hot under hard vacuum for several minutes. Some sputtering occurred but thats better than contamination.
Still groggy however.

oh very nice! looks quite nice too! it certainly is progress Smile what sort of arc voltage are we looking at here? im assuming 8W T5 electrodes so 170Ma for current?

just read on your facebook post it has cathodes from an 80W T5 that explains the dark section behind one of the electodes, that being said it would mean it has 555Ma cathodes that would be a bright tube i wonder what the arc voltage is at that current
