Looking and waiting. Bought that exact shower head last weekend for my 75mm lens. Thought I might put it on the mean green PT120. Did do some espearminting and focal point is almost at the end of the shower head base. Watching with extreme interest OL, you are the trail blazer here.
75mm, the one I have measured, came out to (approximately) 56mm distance for square die focus, but that was with an XM-L. Yes, I’m putting a 75mm aspheric in this, from wellparts (ebay).
I don't think the website shows everything the local stores have. Some people said they carried the Ampro 3AA light (here at Amazon) but I never found it at the store or online.
I don’t have a part number. It’s in most stores, but not all stores and it does not show on the website. I have found that type of thing before with TS. If I get by there soon, I will get the part number, if they have any.
I can tell you it's 100 led and takes a 4AA battery holder.
