Hey guys, I just got 5 of these from Mountain Electronics and at first thought the popular 4C was for me. Now I have discovered 6A and prefer the very warm light even though they are dimmer. So these brighter 4C are extra.
I have 5 to sell, only one has seen any runtime, and that was less than 1 battery charge. Just $3.49 each! PM me if interested. For that price you could change the board and still save big.
UPDATE: Shipping in the US is averaging $2.75.
