Weird SIPIK SK51 1AA/14500 latern/zoom flashlight thingy

That's a rather unusual design for an 1AA/14500. A little too bulky for my taste... but it offers something new. The price of $13.60 for a multi-mode XP-G R5 with these functions makes it tempting to order one, though. At least the light that would normally hit the walls in throw mode is used on this one and not wasted like nearly every other budget zoomy I know. Would eventually make a nice bike light, so that you can be seen from the side while riding.

I saw that too, and I think it's a clever idea -- particularly useful for the 1+ billion people who don't have electricity!

This has flat glass on the front, not a lens?

Does extending the front just move the reflector off of the LED -- or is the back side of the reflector also reflective so that acts as a cone to spread the light sideways more effectively?

My guess would be that it is just a push-pull zoom with "clear walls" and an aspheric lens at the front. The second picture indicates that the led star just sits there with no "primary optics".

It appears to use a TIR lens, rather than the typical aspheric. Interesting.

Yeah, you are probably right, as is doesn't "stick out".... I thought TIRs are only effective when directly attached to the emitter... wonder how that works out.

Thanks for the heads-up!

Very interesting, it seems that you operate the zoom with the knurled ring next to the tailcap (?).

The TIR looks like the lenses LedLenser uses e.g. in the H7 which is not giving a particularly smooth beam pattern but works well otherwise.

The TIR in my DQG tiny II is producing the best "all purpose" beam I have on 30+ lights. I think it is hard to estimate the beam profile on TIRs... one has to experience it to see if it is likeable or not.

This certainly is odd. I’m not sure what is going on actually.
Is that really a clear plastic tube in flood mode as some suggest or is it just taken apart with the light turned on? That’s what I think is going on.
It looks like the zoom is by twisting near the tail cap. I don’t see how twisting near the tail cap would extend the light revealing a clear plastic tube? If it were push/pull maybe. Also the beam would be very ugly I would think.
It’s odd that this light is running on 1 AA when it’s big enough to be using 18650. It has a 32mm head.
I don’t see much difference between throw and flood. It’s using a XP-G and aspheric so I think it’s going to have a slightly narrow beam in throw mode and a slightly wider beam in flood. Flood will just be a defocused TIR. The collimator in the middle looks fairly large so even defocused it should be able to catch some of the light.
I think the light would probably be better off as a 18650 using a fixed TIR.

Here more pics... and it's also listing under camping lights... so it's pretty safe to assume that it has some sort of latern mode.

Yeah, appears it's still a twisty zoom:

And I agree, it definitely should be 18650 considering it's size. Well, it would need to be lengthened a little, but might as well.

I would guess it's a push\pull zoom using a small aspheric recessed into the head with a flat lens attached by the bezel.

Why do you suppose they have the arrows indicating a twisting action in the photo I posted above if it's a push/pull? Just trying to figure this out :)

I have no idea why those arrows would be on the back. I cant imagine some fancy internal zoom mechanism on a $13 light. You never know though. All I know is that I know nothing about this thing and wish somebody would order one already.

Well, we saw that clear plastic thing that comes out the front so it's possible the tail cap is connected to that so essentially the metal body tube is like a shell. Although, that sounds kind of complicated for a $13 light and I'm starting to doubt my own theories

Why do they have to publish critical information embedded in the jpeg's so the search engine can't translate?!!!

my guess is

the TIR makes it a thrower w/ the lens UNextended, and a lantern w/ the lens extended

if they hadn't screwed up the battery/size (should be 18650) I'd have ordered when I saw it just because its different

I don't have much use for a 'lantern' that has to use the (small selection) of <17mm drivers, and is maxed out at 2c of li-ion 14500s

make it 18650 w/ xml at 3A, keep a 10' glow lanyard in your pocket (for tossing it over a branch in lantern mode) and you'd have a heck of a camping light

Maybe the "screw" at the back end of the body is responsible for minimal adjustments of the height of the emitter tower, resulting in big changes in the TIR beam and the push/pull action is for lantern mode only. This would also explain the thickness of the body, as there would be a "tube in a tube".

I think you might be right. That might mean the heatsinking isn't good enough for a well driven xml.

The black and decker/rayovac flex360 clamplights are twist zoom and use a TIR optic

seems to work well w/ the xml I stuck in one

I think it’s funny that we have to guess what a lights features are :slight_smile:
You would think if someone was selling a twist zoom with pull lantern feature they would say so :slight_smile:

it is just a game of stump the flashaholic.
