For $10, I didn't expect much, so it met expectations, but still some interesting things:
very moddable - easily comes apart: driver retaining ring, uses the technique of long LED wires so they can twist around when threading in the pill, etc.
lower qual threads, finish, plastic lens - looks good though, no grease on threads, etc.
on a good cell measures about 1700 lumens at turn on -- not bad actually for stock as-is
uses a fake/clone XHP50 LED that runs at 3V - confirmed this from testing, and tracing thru the driver, CW but tint in this zoomie is not bad. Classic quad LED display when fully zoomed out for max throw
separate USB charging board - well, it's mounted to the driver, but looks like a driver replacement can be done with retaining the USB charging
classic klunky 5 mode UI: hi-med-lo-strobe-SOS, then OFF - must cycle thru modes to turn it off, always starts on hi
tail lockout from one little twist
Interesting driver design, just 2 small FETs, no resistors in the path, skinny long LED wires (24 AWG), normal gold plated springs.
Yeah weird. Since the HT08 apparently wasn’t received that well and sells for pretty much the same price, it must be overstock they sold off.
Exactly the same UI too, doesn’t look like a cheap copy.
Looks… interesting, but really not interested in the fresnel lens. They’re quite lossy compared to aspherics, and zoomies are already pretty lousy lossy to begin with when zoomed.
Forget about the description (50000 lumens) and the UI ( ), but being a zoomie with XHP70.2 and eventually a push-pull (not sure of this), it would be interesting.
Getting a driver with a good UI would turn it into a nice light …
I have contacted them for the ” On the Road Z821 light (the one with glass lens) and never got an answer… I need larger quantity and OEM service but it is hard to deal when they obviously don’t have costumer service
Last time I contacted OTR CS it took some days to get answers! I believe they are more focused on the chinese market, and in platforms like Taobao or Tmall!
So I am still in a search for small zoomie host with glass aspherical lens, 18650 cell only (1” tube), andodized threads, without redundant parts like usb charging port…
So far only OTR Z821 has all this qualities… Looks almost perfect… But manufacturer not available for communication. And they probably discontinued Z821…
