ITS HERE! SIPIK SK98 - A 18650 based Sipik SK68 with an XML!

to desoldered itself this mean huge amount of heat,you should not be able to touch the flashlight.

That would be the case if the heatsinking was well designed but all the heat stays on the LED star (although i added some aluminium on the back).

After read through the comments, the SK98 still kept the week craftsmanship of SK68, thanks for your opinion and advice, we hope everyone would notice the SK98 is week in heat dissipation before go to SK98. it seems that some people take it as a acceptable one.

I received this one yesterday. After I applied the aluminium foil trick the body actually seemed to get less hot than before. I let it run for 20 minutes and it gets warm but not too hot to touch. I also have a SK68 and the biggest difference for me is that the zoom-mechanism is much smoother on the SK98 (it’s a little loose actually). With this light you can change from flood to throw with your thumb while with the SK68 I need two hands to change the zoom mode. And of course it gives quite a bit more light than the SK68 (with a bigger hotspot). Flood-mode is perfect and throw-mode is nice to have in the same flashlight but nothing special imo.
I’m happy with it, especially for the price I paid for it :).

Welcome to your new home, Snippo!

Has anyone considered doing a strobe delete on the driver? Is it possible? I know someone was suggesting to get a 3A single-mode. I’m considering options. I like how the SK68 is single-mode. I think a trick zoomie like this doesn’t need low or blinky modes.

I got one of these & inserted some foil behind the star & put some thermal paste on too.It gets warm but not mega hot(Sipik version by the way) For the price I can’t complain but it’s not mega bright in my eyes for an XML, I reckon my old spiderfire P7 is brighter. But it does throw further.

Against a HD2010

Just an update: The UltraFire sk98 clone is still going strong, and I’ve had no over heating issues. It remains bright and reliable without any heat sink modding. My Sipik SK98, however, has been disassembled indefinitely until I decide I want to heat sink it properly.

So to reply to my own post, here is a photo of the driver module from the SK98:

it’s definitely 20mm. Anyone know a source to buy a new 20mm single mode driver?

One little advice from me, don’t use a 2eurocent coin for heatsink. it’s made from iron which is a bad heat conductor.
A 10eurocent coin is much better because its made from copper…

Meritline has this for $9.99:

Mine hasn’t arrived yet. I’ve orderd on 4th October on mana font. Normally the manafont packages arrive very fast I’m so upset.
Anybody else who is waiting?

The UF version retained the 3 modes from the 14500 version, might have to grab one

Save yourself time and money…rewire it for direct drive.

So finally mine arrived today, so I had to make my own coin…
For the first tests I use only thermal grease and no glue but it seems to work good, without heat sinking the flashlight doesn’t got hot and now it directly gets warm…mission accomplished.

The zoom is harder to move than the sk68 one. I have lubed it a bit up and loosens the pill that helped but not perfect. The mode changes every time when I switch it on. It seems not much brighter in flood with mid mode.

Has anyone tried this in mule mode? As the sk68 (clone) easily lights up my backyard like day with fresh charged 14500 trustfires with the bezel+lens taken off

Yes you can use it without lens, big flood of a XML.
But the driver has a so strange memory which every time you switch it on goes to next mode, I hate that.
So I have changed the LED to an U3 and I am going to put a good driver with 3A and switchable modes in it. Only Problem is the driver I wanted to use is a 17mm and you need a 20mm for the SK98, so I Have to get a copper ring or so.
Another possibility is to fill it up with aluminum powder and epoxy…I am thinking about it.

Perhaps my coin mod was not perfect, an aluminum cylinder which fills the whole pill till the driver would be perfect.

If only the Chinese listened to the suggestions on this forum!

the sk-98 clone from fastech have good dropin with aluminum under the led pcb :smiley:

this one

I have received it today

nice, the best we have seen so far…

if you want to leave the stock driver and if it has next mode memory: Attention! Solution for most of those next mode memory drivers!
if you want to change driver order this adapter board to use a standard 17mm nanjg: https://www.fasttech.com/p/1138202
