This one appears to be a new budget model from MXDL. I like the looks of the knurling throughout the body on this light, and MXDL normally produces rather nice products for the price. They are a branch of Romisen.
At those prices, if it emits light, you are probably ahead of the game. They are quite likely brighter than most of my Luxeon 3 lights from a few years go. They are certainly cheaper. think I paid $30 for a direct drive Luxeon 3 light and that was very cheap.
Neither of them actually explicitly state voltage. At the price, if a 14500 kills them they can always be modded. I'd guess they are aimed at alkaline users - will see what sort of currents they draw from alkalines and Eneloops first.
This is why I like eBay, the sellers realize that many buyers will be scared off if their approval rating is anything less than 99%, so they really go the extra mile to ship quickly. The DX-type companies seem to feel that their customers just need to be "patient" and deal with it. My cheap $4.99 Zoomable flashlight also shipped just now. DX and the likes could learn a thing or two from these small-fry sellers.
