These fiber optic kits are expensive and some what limited. You can buy fiber optic cables on ebay for not too much and you can make your own holders to position the cable ends near your strobe. Spare strobe covers work nicely. You can also add a lens in the holder (fresnel or magnifying glass) to concentrate the light from your strobe into the end of the fiber cable. The industrial light sources use a dichroic filter to removed the IR from the light to provide a heat less light which can be important for some subjects. You can buy those filters at places like surplus shed.
This is what I was thinking and have been looking up info on fiber optics. Is seems like the materials are pretty cheap and it is easy to get light to travel though the cable.
I spoke to an engineer about it too, and he said that so long as the cable is tightly held in place and the fibers are flush to each other, light travel is fairly easy to achieve.
Now it is just a means of attaching the cable to the strobe. I came up with a simple design with several cables, but they would all be bound together. I feel this is too limited though. I want to be able to remove and add cables at will.
If I ever need to have a cable hidden under someone's clothing, running the cable through their sleeve and down the body and leg would be easier, and less awkward, then going up the leg/body and out the sleeve.
