In fact, the dip HID on it's own probably throws out enough light to make the need to also convert the main questionable, but with both dip and main HID lit I can nearly cause an eclipse.

Converting the main was a bit more of a faff than the dip because the bulb holder is different, and requires a bit of resolute dremeling. Not difficult, just fiddly.
