I'll try to do some longer range shots when i have the time. Actually the jump from 55W -> 75W is smaller in difference than i have expected.
Actually that is already 100m distance, that is why the XM-L seems switched off.
I'll try for 1.1km later.
I found a good deal for 100W ballasts (the black finned ones which is documented by Lips/Stollman/BVH) with 2 x 75W bulbs....$88 shipped. And also a 8" HID 55W ballasted host at 54 shipped (that one which BVH described as crappy reflector at the base hole which is described as just "hacked off"). Buy both and get another $7 off savings from the shipping! Think I am going for it.....
That ought to complete the line-up together with the LP-250NS. Until I go crazy again and go for the kW short-arcs.....heh heh.
