Stainless Steel 18650 lights

I was just browsing DX and found these:

Spicer Fire X-07 Cree Q5-WC 2-Mode 230-Lumen LED Flashlight (1*18650)

Spicer Fire X-07 Cree Q5-WC 5-Mode 230-Lumen LED Flashlight (1*18650)

Aurora SH290 Cree R2-WC 2-Mode 240-Lumen LED Flashlight with Assault Crown (1*CR123A/1*16340)

Im not sure but the 18650 version looks like it could convert to 16340 by removing the spacer. The lights look identical to me otherwise. Does anyone have one of these? If anything, they look like nice P60 hosts.
