Here’s a TinyReview of a TinyDeal giveaway light, the UltraFire 503B Cree XM-L T6 900lm 5-Mode White Zooming Flashlight - Black :

Size comparison with other well known zoomies (mouse over to see zoomed in):
The pictures on TinyDeal website are accurately portraying the quality of the body. My sample didn’t come with any major scratches or imperfections of the anodising, except on the 90 degree angle edges, just like in this picture:
Because these edges aren’t rounded, they are kind of sharp-ish. Don’t get me wrong, I doubt you could get scratched or otherwise injured by handling the light without trying hard, it’s just not as smooth to the touch.
In pieces:
The threads came in dry, after some grease they are nice and smooth, no complaints there. I think the tail end o-ring is too small, because it doesn’t seem to add any resistance when screwing the tailcap on, so I suspect it isn’t making sufficient contact with the tailcap thus making the light not waterproof. The zooming mechanism o-ring, on the other hand, provides a nice amount of friction and the whole zooming action feels very good - not too loose and not too tight.
The zooming mechanism o-ring is not on the pill, like in a Sipik or Zeusray, it’s on the body, so spinning the zoom head counter clockwise does not unscrew the pill, to do that you have to hold it with your finger. The head slides freely over the pill, and if you grease the pill I doubt it could ever get unscreewed by rotating the zoom head.
Driver board is 17mm in diameter. The pill is hollow, with about 12mm of empty space between the driver and LED board:
The driver is a pretty much standard 5 mode one: High > Medium > Low > Strobe > SOS. And it has memory. Thankfully, using pencil mod I managed to make memory only last for less than a second. This way a quick half press still advances the modes, but a slightly longer one (or a full on-off cycle) defaults it back to high. Goodbye accidental blinky modes!
This light uses an XM-L T6 LED on a 16mm aluminium base.
The beam in flood position is wide, but not completely round, a tiny bit squared off. It’s hard to capture it on my crappy camera, the squareness is a bit more pronounced in real life:
Zoom position has two bright rings:
Tailcap current reading was done with a freshly charged protected Samsung ICR18560-26F.
High: 2.50A
Medium: 1.31A Low:
0.37A
In conclusion, it’s a decent light. Yeah, the quality is not perfect, the tail end o-ring is too small, beam has rings, no clip, hollow pill, those damn blinky modes… But that’s what you expect for the price. Unless it’s a Zeusray
