What is the disadvantage of using car bulbs then? Presumably if they're
more robust and seemingly just as good at lighting things up, there must be
some downside otherwise they'd be used in dive torches too...?

the downside of using car hid bulbs is that the color temperature is only of
4500°K Vs 6000°K for the welch allyn type

The balasts I have are rather large to go in the light head, I think I
have read that the bulb will still strike with the ballast located in
the canister. Do you have an opinion on this?

This is right, the only reason why the bulb as to be close to the ballast in
a car is to overcome the EMC distorsion "the high voltage at ignition could
generate radio problems in the car's electronics, like jammed your cruise
control driving at your usual 150 mph ! ;oD). Seriously, I've tried an HID
bulb 3 feets away from the ballast and it works just as fine.
Sorry about my poor english level....hope you understand !

Alain,
No worries.
Your english is far superior to the Americans who occasionally post
here.
Let alone the Scots.
