Press it out. The o-ring and friction are holding it in. Clean the hole and lubricate the new o-ring when you reinstall the new part.

. . .

The black plastic nut retainer ( it just keeps the nut from turning) is held on to the housing with double sided sticky tape. You will have to remove the coating from the new plastic nut retainer.

Hope that helps.

Hell, *yes*, it helps! Thanks! It took about half an ounce of pressure "press" it out. The little wifey had to ask what I was cracking up about when it popped out so easily. :-) She might even get her kitchen counter back if I can figger out how to remove that "coating". Probably wouldn't have thought about greasing that o-ring, neither. . .

Ran across one of these about a month ago at the Blue Heron Bridge.  Only learnt today what it was.

Tested it out while in the darker areas under the Blue Heron Bridge last weekend. That's not a lot of light that it puts out, but it worked exactly as advertised for helping with focusing when there's no sunlight.

On three dives with my 60mm macro, I also tested out +4, +7, and +6 diopter setups - my first attempts with screw-on diopters. It worked out that with the light pointed down as far as it can go, it was just right for the closest focus with +4 diopter, but it doesn't aim close enough to the end of the flat port to get the most out of the +6 nor +7 diopter setups.

While it would be hard to imagine that this light could cause a "hot spot", there's no danger of it, as the light turned itself off for a second with each flash of my strobes.

As an aside, I *love* what I can do with the diopters, but the loss of flexibility can be aggravating at times.

If you are talking about the $49 fisheye mini focus light:

Yes, it works great, and is all you need.

A YS mount is the way sea and sea mount their strobes. So it is easy to get a short ball arm that plugs into the light bracket:

And get a 1 inch ball that screws into the top mounting hole and twin clamp.

Thank you! And that pic of the YS mount helps. I'm guessing that the ball arm has a screw on the end opposite to the end that the YS mount attaches to, no?

Since I last posted, I took the top off of an old, broken tripod, turned it upside down, and the screw fits the hole in the housing. I'm thinking that some acrylic for making impression trays (and maybe a little duct tape, if necessary :-)) will get me going with the 39.95 mini focus light from B&H or Adorama, with no further purchases. Wonder why he didn't show me that one at Reef. . .
