DIY YS-adapter for Keygos light?

[corbinco2]

I just ordered a Keygos S9 light on eBay based on recommendations elsewhere on this board. Any ideas on how to connect this light to a Fantasea flex arm with a YS end on it? The light is a flashlight shape with a minimum diameter of 24mm. Here is a link to the ebay listing: http://www.ebay.com/itm/KEYGOS-Divi...ping_Hiking_Lamps_Torches&hash=item46057f10fe

Here is a photo of my final solution. I used an Intova Torch Adaptor for a mini-torch, which was almost the right size. I needed to file off 1/8" of the arm and use two plastic spacers to make it tighten. The light is very bright--1400 lumens with a small hot spot, so I made a diffuser from a rubber hood for a landscape light and a translucent SLR body cap. Best I could do while on vacation in Cozumel Hopefully I will get a chance to post some night dive video with this rig.

I finally got some videos up on YouTube to illustrate how my DIY video light rig works. One caveat: I bought two lights, a Keygos S9 and a S3. They are very similar with the same very bright 1400 lumen output. The S9 flooded the second or third time I used it. The company I bought it from gave me a refund, no hassles. The S3 worked well, so I am going to buy another one and use a double-light setup for night dives.
