Subject: Re: HID Light Question

"John Walker" ????
Funny stuff , things were getting boring.
You wrote.
  The question was:

  what will happen if you accidently catch your light cord on something
causing the E/O connector to become unpluged?

   I believe his question was pointed towards the fact that hot striking
or restarting an HID light could be problematic.

My response; Yes, a possible issue with an HID with an E/O cord. This is
true.

You wrote.

   I simply stated that a "COMMON PRACTICE" was to carry a 2nd light
(possibly halogen)with a plug, test tube and e/o pig tail.

My response; Common practice for who ???? As stated , I dive HID, as do most
of the guys around me. We have for awhile now. We don't use E/O cords, not
an issue to be addressed.

You wrote;
   Furthermore, I never said this was the NORM. I said it was a

My response;
Your direct quote;

I'll be damned, it appears as if you actually did say this was "the norm".
John,(?) perhaps YOU should go back and read the posts.

BTW, that's "Cheers".
Regards to you "John Walker".
 P.S. I like the last part too, nice touch, but pretty stale ;-O
