With all this said, which spot light replacement do I need?
That has been the difficult question. Even when using 5000k color temp HID bulbs I don't remember anyone finding a spotlight that was a good visual match.
Chuck was going to try HID spots but the bulbs wouldn't fit in the light housings. This mftr might (or might not) be different there. Using HIDs in the spots would also mean another pair of ballasts inside the fairing. If I knew the bulbs would fit I'd do it anyway. Especially for the cost of this mftr's kits.
I tried a couple different spot bulbs. All marketed as being at least a comparable color temp to the HIDs I'm using. Not even close.
So either bite the bullet and get good light while just not worrying about the visual distinction between the old and new bulbs or, if the uglyness really grates on you, leave your spots turned off.
