Joel,

You really need to try one of these in crap visibility with tanic stained
lines. The HID light is incredible. It is as though it slices through
crap water and locks onto the line without all the backscatter you would
see with a normal bulb. If you are imagining this as simply a brighter
then you are mistaken. Extrapolation from what you've experienced with
standard bulbs doesn't hold.

BTW, I can't imagine why you would want to close your eyes, particularly
if you are suffering from vertigo. The way to deal with vertigo is to find
some visual cue. The movement of silt that you can see half an inch or so
from your mask with your light on is such a cue. The last thing you want
to do when suffering vertigo is to close your eyes.
