After looking at a bunch of sites, I chose the Dapper OE7 LEDs, with the "vintage" lens. On sale - just under $300 with shipping.
Thanks all, but the discussion can continue...
I was leaning toward the HID option on the Dapper V1 light, but the Applications Engineer talked me out of it. High start-up current (vs. LED), 10-15 sec for the light to come up to full brightness, and the potential for the light output to gradually reduce over time. Sounds like a PIA, and that the current generation LEDs are the way to go, in whatever package you choose.
Thanks to everyone who provided guidance.
