Neat, and I am really liking your CalSci shield. Those guys have the science down pat.
Your comment regarding warm-up time for the HID's is why I chose to do a main beam replacement of the stock light with the bi-xenon projector HID. The burner stays on at all times and a solenoid changes it between low and high beam, so warm-up is only when I start the bike. Actually the lamp has a CCFL Angel Eye and I have built the circuit so that it wakes up in Angel Eye when the bike starts. However, if you select the high beam, the xenon high beam comes on. Thereafter if you press low beam, the xenon stays on and switches to low rather than switching back to Angel Eye and turning off the burner. I did this so it would not be possible to fast-cycle the HID by switching in and out of Angel Eye. Once I light the HID, it will only go back to Angel Eye when I stop and re-start the bike. Sometimes untrained button-pushers ride my bikes and also, I like to set them up for multiple use of existing switches rather than adding switches when possible.
I recall a warning in the owner's manual of an HID flashlight that said if an HID is run for less than a minute or two per burn you can plate the inside of the tube and cause light reduction and eventually overheating and failure. They recommended at least letting it come up to full brightness before shutting it off. Further, every re-strike is putting 23,000 volts to the lamp and causing some arcing wear on the electrodes. The ballast lowers the voltage after the ignition strike to only what is necessary to maintain the burn. Bulb life is as much or more dependent on number of starts as it is on hours of operation.
Lots of the Iron Butt crowd use HID's for driving lights for long runs on deserted highways and they are extensively used in off-road and desert vehicles. If your riding allows them to run for reasonable periods of time they will do quite well.
