the DDM's were the best in measurements. however, you will always have a sacrifice since the incandescent filament is perpendicular to the reflector parabola, and the HID arc is parallel. but i havent come across a perpendicular arc lamp
I got my hella lights in, they are awesome quality just by looking at them externally. Can't wait to get them fitted and wired up (may take a little while as other priorities have come up around the property...)
