Subject: Re: HID Light Question
Whatever Dell. 
 
  You must be bored. Here are a few people that do it this way. Keep in
mind that the glow from each of their persona's does'nt actually require
them to carry any artificial lighting into a cave. They do it just to
keep folks like you in a quandary. Go call them. 

     Jarrod Jablonski
     George Irvine
     Barry Miller 
     Oliver Isler
     and there are others but who cares other than you?

   OK, I did state that for redundency on this particular light head, a
halogen back up seemed to be the norm for now. You don't have one of
these light heads with an e/o connector to even consider any sort of
redundancy with your primary light, do you? 

   Let me guess that you think that this idea is profound and you feel
everyone should go out and buy the Dive Rite HID along with one of your
fine modular lights. Hehehehe. Sorry Del to have to tell you this but
your company doesn't offer one single piece of worthy equipment. 

   Maybe you should spend more time designing a decent product rather
than picking through e-mail posts and correcting the grammer.

   For anyone reading this wondering where to buy quality products
contact you nearest dealer of:
                               Barry Miller product
                               Halcyon products
                    or contact Extreme Exposure 800 378-7820 us/canada
                                                352 377-2547 interna.
  
   CheArs, John
