This one looks reasonably attractive for $5.48. I have seen an even cheaper flashlight design that appears similar to this one, called the SmallSun ZY-C575, but I'm kind of turned off by the head design, which appears to unscrew right below the reflector, leaving the emitter and the board still stuck to the body tube and apart from that the head with a hole through the reflector. However this new one from KD doesn't show the light unassembled, so who knows if it has the same design. It does appear to have an upgraded endcap with orange switch boot. Can anybody discern from the blurry picture what kind of LED this has? It almost appears to be something more than the typical generic glowing epoxy that is common in this price range. Could it possibly be a Cree or OSRAM?
When i downloaded the pic of the first one and hit it with some brutal unsharp masking, it still turned into pixel porridge when I tried to look at the LED. The die area seems to me to be too big for an Osram but it is possible that it is one of the ringless Cree ones - it almost certainly isn't an XR-E. At the price it might be an XP-C or XP-E.
An SSC P4 is probably very cheap nowadays, especially if it is one of the lower brightness bins, S or T. It is entirely possible that both contain an SSC P4 - they are going to be cheaper than Cree LEDs
I also own the zoomable light, bought it off eBay, and mine is definitely an OSRAM. Mine is actually quite bright and has a very nice beam. But I wondered if maybe they changed the LED on the KD version. But as Nautic says, I would suspect that it's the same as all the others and KD has made a typo.
