Re: [PSUBS-MAILIST] Under water lighting

Generally, the brighter the better.  But a lot will depend on how murky the
water is, and what's making it that way.

In some inland areas, the visibility is so bad due to mud and crud suspended
in the water, visibility is reduced to a few inches, and a light is almost
useless unless you've got your nose right up against the object you're
trying to illuminate.

Where will you be operating; how's the visibility; and what makes the water
murky?
