A twin-arc halide... now there is something you don't see every day.

If it’s anything like those Sox I pulled out of the lamp bin at Eddies, their probably NOS, contractors are just binning HID now for the sake of it!!

update all tested good nice and bright on startup showing that the arc tubes are not blackened much the two hpis date from 2001 with old style philips logo and one is teflon coated, even the 400w merc is ok nice and bright with 4M (dec2014) date code

Awesome saves. Yep contractors bin everything thats not LED - The opposite of what you'd expect from people with atleast some sense to lighting
