Some Costco/Harbor Freight HID's have better focus then others. It is more a function of how well centered the bulbs are then their vertical orientation.
A little scoot in the right direction will make a big difference.
My well focused Costco HID has a lux reading at 37 feet of over 7,000.
My okay focused Costco HID has a lux reading at 37 feet of around 5,000.
Take Care,
