Subject: New DiveRite Light

Roger,

Thanks for the report, it is appreciated!!!

Been rumored for a while now.  They (yes, even Dive Rite) realized
that their light sucked raw eggs, but, they still had mortgages to
pay, etc so they kept the neutraleak out there.

Hmmmm... Well most "normal" openwater dive lights (e.g. UK1200, etc)
have screw on heads, ok...  It will be interesting to see where the
"O" ring(s) are, how they're seated, the style/pitch/etc of the
threads, and how much out in the open they are, making themselves
availble for damage/etc.

This would be known as marketingspeak, or, in other words, a *lie*, if
indeed you described it correctly.

Video lights have entirely different beam patterns attempting to FLOOD
the landscape (floodlight is a good word here) with a relatively
constant illumination.  This is needed for the video cameras so one
section of the CCD does not appear totally white while the rest is
very dark.  Anyone who has ever taken any underwater video knows what
happens when some well meaning divers shine their lights across your
video field, it washes out that section of the video (they think
they're making it MORE visible to the camera or something like that).

Normal lights have much more focused beam patterns aiming their beams
in a relatively small cone, aiming for penetration versus coverage.

So, in order to switch lights, a different reflector would be a
MINIMUM as well.  In order to "gang" these batteries they're probably
using E/O connectors which add greatly to the cost.  I'd bet dollars
to donuts that it would end up MUCH less expensive buying a couple of
high powered AUL lights (250 or 300 watts) than buying some of these
DR units, but, time will tell.  Since I'm not making it to the shows,
I'll rely on others to report back their findings :^)

Thank you for the information...
