Hmm, no idea, those date codes are indeed very confusing, looks like manufacturer keep that for them self

Also one more thing, does this lamp allow universal burning position?

Yep 1200 = December 2000 and the code HgMI/DV = Hg = Mercury MI = Metal Iodine additive, D = Daylight Colour (6000 deg K) and the V - Vertical Cap Up/Down burning only.

Yep if you burn the lamp horizontally the arc will overheat the arc tube and can cause the whole lamp to explode violently. this lamp is designed for burning Vertical example in a Industrial Light fitting with a Glass Cover. example see photo

Yep Metal Halide Lamps operate at a higher pressure then Mercury/High Pressure Sodium Lamps at 50 PSI (Pounds per Square Inch), still it's nothing compared to Short Arc Xenon Lamps which have extreme pressures at over 400 PSI example the XBO LAmp as used in Cinema Projectors and Searchlights, etc. and when they explode they explode like a bomb even when cold.

example see HERE
