The light is flawed with small solder pads and the MCPCB is only 66-75% of full size.

I opened the head and saw what appeared to be a good solder, desoldered. It was sent back.

In addition to this, the last light I received appeared to have been used and resold (SS crown & lens scratches). Still in good shape but the current draw was only 1.5A. Of all the other C8s I received, this was slightly low. If they get offered again, perhaps some may be refurbished.
