You may find this more interesting and more creative lighting you can achieved.
I have attached a fiber optics to the Sidekick ( Light & Motion).
The greatest thing is that Sidekick Duo have two ligthhead, one spot and one flood.
They can be switched on individual or both at the same time.
So you can have a spot light effect or flooded light , or combination....or backlighting....
so much fun with that.
The cost of the DIY is only US$10, a bit expensive than yours.
Will have it used for filming next week at Scuba Sereya,
