Just got a pair of DS-125 strobes. They have the modeling/dive lite feature in them, which I did not have on my old Sea&Sea. Are these lights practical solutions to take the place of a dive lite for night dives? How about with the diffuser on them?

And any difficulties in using them for a focus light? (Canon 20D camera.)

They work fine as dive lights. For macro they are a good focus light but I don't like them for larger subjects due to backscatter from lighting the water in front of your subject.

I use a single DS 125 modeling light (don't need both on) at night to find things, but if it's a crustacean or any other skittish creature that I want to capture, I turn it off immediately in favor of a red lens spotting light which works acceptably to achieve focus lock with my Olympus c4040.

To create a night dive red focus assist light, I placed a piece (cut to size with a scissor) of Roscolux #027 film inside a flashlight. Just place the red film between the reflector and the inside of the lens and screw in place. The film is extremely thin and from my experience will not detract from the watertightness of the unit (YMMV :blink: ). I've been successful with this approach with a Pelican 4D and a UK mini Q 40.

i have used these strobes both singly and as a pair for night dives. They give easily sufficient light to dive by. However they do not have much penetration giving a fairly diffuse light and this can make it fairly difficult to navigate if you need a light to look for the bottom of a boat say.

If you are diving with someone with a powerful light - one of my regular buddies has a light cannon - then you may feel that they are not strong enough because his light will overwhelm yours. However diving at a distance from others they are fine.

I like them because it means less clutter on a night dive and less of a tendency for all the night critters to disappear in the sun like beams of some torches.

One is more than sufficient lighting for me on a regular night dive.

I turn one to staging leaving the other set to on, then switch halfway through the dive...Just in case I didn't charge them after the afternoon dives.

Well thanks for the feedback. I feel more comfortable leaving one of my dive lites at home now, and just carrying a small backup.
