I actually went the more experimental route.

Haven't yet installed the lamps though. (don't really have a full day to start projects without planning a day off work)
Plenty of space beneath the extended caps to keep them cool.
No external driver but the plug is huge; which if in the wrong place, can interfere with aiming the headlamp. Over time, abrasion wear will create some additional dust.
