Only thing I complained about regarding my lights was that one of the lights came rather scratched and that none of them were really waterproof, so I got partial refund due to their misleading item description, its fairly easy to get water under the lens if you happen to drop it into water or leave it outside/hold for prolonged period of time during rain and there is no way to get rid of that water unless you unscrew the lens cap and wipe it all dry yourself, otherwise it stays there...

There's an inherent difficulty in making small zoom flashlights like this one waterproof.  Especially for lights with relatively smooth push-pull zoom mechanisms.

I encountered this when modding my Sipik SK58, which is similar in size and uses a similar zooming mechanism.  The light originally came missing o-rings and with a metal C-ring in the o-ring slot on the sliding mechanism.  This made a metal grinding sound every time the light was cycled from zoom to flood ... and meant that air could get in and out so the light was not waterproof.

I took out the C-ring, added o-rings in all the o-ring slots and lubed the o-rings up with Nyogel.  The light was now waterproof.  But there was a major problem:

Since the light is now air-tight, cycling the light from flood to zoom is much harder.  As the light is expanded to zoom mode, internal volume of the light increases.  This causes a reduction in internal air pressure.  Since air pressure outside the light is now higher than air-pressure inside the light, the bezel would now retract on its own as the air pressure tried to equalize.  Result was that I'd have to physically hold the bezel in zoom position and if I let go it would slide back to flood on its own.

Assembling the light with the bezel in zoom mode caused the reverse problem.  When I pushed the bezel back towards the body it would increase air pressure inside, which would then push the bezel back into zoom mode on its own.

I solved the problem by removing the o-ring at the lens.  This allowed air pressure to equalize  and resulted in a silky-smooth zoom cycling with the bezel staying in whatever position I left it in.  My conclusion was that it's not practical to make a zoom flashlight of this size and with this zooming mechanism watertight.  You might make it splash resistant with a very tiny gap, but if you want a watertight light, you should select a non-zoom light.

Now I have 3 clones, my preference is to have some of each kind, single and three mode, but I could do without the strobe.

After about a year of EDC I am planning on trying some physically smaller lights, starting with a higher output mid price 1xAAA like a Thrunite Ti2, for more convenient pocket carry and leaving the SK68 clones for toolbag or glovebox.

I measured some tail cap currents and was surprised by the spread. With maybe half an ohm in the leads and a 0.6 AH AW IMR charged up to 4.2 V, I got 1.5 amps for a Sipik, 2.1 A for one three mode UltraFire, 0.8 A for another 3 mode UltraFire from a different source, etc. The light output varies but apparently less and not well correlated with the current. I had been supposing that the drivers were all similar, but that is apparently not the case.

Those batteries are not good and that charger is not safe. Pick up some Sanyo 840mah 14500 batteries and a real charger.

Many of the cheap lights have high losses in the case connections.

What kind of leads have half an ohm of resistance? Seems really high, but I haven’t measured any.

I would not put Lion batteries into the hands of anybody that needed good ones. Yes the output is much higher, but Eneloops do fine and have no risk. I use cheap ones, and monitor the charging on a cheap B6 and pay attention to drooping output when in use. I don’t feel all the comfortable using Lion and maybe for now that is how it should be.

GF glovebox light, premium Alkaline or Eneloops, would be my choice.

Ceiling bounce comparison with my three seem fairly similar on high. Maybe you got some bad lights?

My view buy several from several vendors, compare them and only gift the best ones.

I just received this one: http://www.aliexpress.com/item/Upgrade-800Lumens-9W-CREE-XM-L-T6-Mini-LED-Torch-Focus-Zoom-Flashlight-Free-Shipping/997633297.html

OMG bright! Uses XML T6 led, way brighter than all my other SK68’s!!! Super nice having three modes too Big Smile

My digital camera (Canon T2i with hacked Magic Lantern firmware) says the XML is 21% brighter than my brightest XRE Q5 I own!

I have one XM-L SK68 I bought already modified and a warm XM-L2 that I switched into one. Better flood at the expense of throw. The total light output depends more than anything else on the current, which varies especially with three modes. I have a lithium ion only driver on order.

I just got an “SK58” from http://www.priceangels.com/SK58-Adjustable-Zoom-Focus-LED-Flashlight-Lamp-Torch-s85918.html . The knurling is much deeper than on my other three. Only the one with the Osram led actually said Sipik on it. Otherwise similar, so I like this one best. Maybe I will switch a three mode driver pill into it. The XR-E upgraded SK58s are intermediate in size between the SK68s and the http://budgetlightforum.com/node/25402 slim zoomy. The light output is closer to the 68, because the head and lens diameters are nearly as large, but of course nothing else AA has the 68’s heat sinking ability.
Added: The swap didn’t work. The locations of the led in the pill and the locations of the lens in the bezel are different. Also the new one has the slide friction spring on the body, while the old one has it on the pill. The focus was off and the slide friction was wrong.
The knurling on the head on my example is much nicer than the one shown at the selling site. The spacing along the head is narrower and there are micro groves on top of the the knurl rectangles, similar to what I have seen in expensive lights. This makes it very easy to zoom with one hand. One of my best AA lights, and I am not aware of any expensive ones that I might like better. Because it has only one mode, I have an Eneloop in it, rather than a lithium ion.

Slightly off topic… I picked up a couple of cheapo Sipik68 clones on eBay, but they came with different emitters.  Both were described as Cree Q5.

 

(sorry. crappy pic but you get the idea)

I believe that the one on the left (from Toptom) is the correct one.  What’s the one on the right?  

I’m almost positive that the one on the right is an OSRAM emitter, judging by the pronounced square in the left corner.

Defnitely an Osram Emitter, i have several other Osram lights with the same emitter.
As for the original Sipik and the various clones, i have one of every variation i could find, and so far the only “real” one, and best one i have is the red one in this pic. it cost around 9 bucks, single mode, has an EZ900 series XR-E, runs well on both AA alc. and a 14500 lithium, has a glass aspheric lens, and so far is still the brightest of them all, with the best Neutral white tint in stock form.
The others in the photo are the various clones i could find and test. The original is found on the Sipik website here:

Did a quick search on ebay just now for cree t6 14500, this one is $8.14 shipped, says five mode, but that includes zoom in/out its just hi/med/strb.

http://www.ebay.com/itm/1600Lm-ThorFire-CREE-T6-LED-Zoomable-Flashlight-Torch-Lamp-AA-14500-5-Modes-/190927316614

Just thinking about it for now, maybe look for a XM L2 for more efficiency. Maybe not, cheapest looks like $27.

Has anyone actually gotten a glass lens in a 1xAA Sipik SK68/clone?

They’re fairly often claimed in the specs on web pages but those are consistently wrong in many ways.

 

 

Mine is a glass lens and 14500’s work fine. Went from about 100 lumens[primary AA] to about 300 or 400 lumens W/ 14500 Battery. I got it off of Ebay a year ago

1600 lumens!!! lol!! I have never seen one exaggerated that much!!

Mine was advertized as 300 lumens, more like 100-150 lumens. With a 14500 I am guessing it is 300 maybe even 400 lumens.

It was my first torch!! I got it for about $7!

If there are glass aspheric lenses, I wonder if they are cut and polished or only molded. I suppose the plastic ones are molded and that plastic can be formed that accurately by molding, but I think you could tell molded from polished glass by how clear it is as a magnifying glass. One usually can tell how a drinking glass was made by looking at it.

That does look like a remote switch. The switch is in the tail cap that screws off, so it would be easy to make a remote replacement for it. People use remote switches for lights on guns and what not.

I bought and gave away one of these http://www.aliexpress.com/item/Upgrade-800Lumens-9W-CREE-XM-L-T6-Mini-LED-Torch-Focus-Zoom-Flashlight-Free-Shipping/997633297.html . One might get the light and the XM-L for a little less than that price, but not by much. It loses some throw but puts out more total light.

I have purchased 4 Sipik clones from eBay in the past. All were very low quality. Just received the Sipik I purchased from Gearbest today. It seems to be a real Sipik SK68. Well made and brighter than all my clones. It is also a bit smaller in size. And has a real Q5. Unfortunately I paid a lot of money for it. It broke the bank. I used my Gearbest points to ease the pain a bit. $2.61 Smile
