There is a standard design perameter set up for lamps. the hid in the halogen lamp is 19x too bright.
Again, answer the simple question...Does the lamp generate the multiple or is the hid bulb 19x too bright?

mcrews is referring to illuminance, others are referring to luminous flux, is that not so?
Illuminance can vary across the field (non-uniformity), and at a given point is a function of luminous flux, source shape and luminary design. 'Multiplication' may arise from 'mismatch' between source shape or location and luminary design.
