Subject: Re: HID & cold water
Erik, 
looks to me like a thermal expansion/contraction problem, different
materials with different coefficeints of expansion, if somewhere
tolerances allow for a disruption of voltage through contacts, a
consequent voltage drop may occur which resets the starting procedure .
I write this without knowing anything in detail about this lamp, so I
may be completely wrong,
jaust my 2cc
