Thanks for your interest in the adapters.
Note: I am discontinuing the polycarbonate plastic (Lexan) adapters. The price of polycarbonate is now higher than aluminum, so it makes little sense to sell a plastic adapter at a higher price than a stronger aluminum one. I still have stock of the Magicshine version and will keep the listing on for those until the stock is gone.
I have black ABS plastic and aluminum adapters in stock. I recommend the ABS adapter be used with single LED lights or the smaller dual LED lights. The aluminum adapter is strong enough for any light that the rest of the GoPro system will hold.
The adapters come standard with a blank mounting tab. The intent is that the user can modify to fit their particular light.
Black ABS plastic $7.50 ea.
Aluminum $12.50 ea.
