My #$%@# pocket rocket >> MT-G2 zoomable SK98

Hi all,

Have been reading blf for months now, really liked the community here and this is my first post so i thought i’ll share one of my flashlight builds
I thought i’ll post it here first as it seems more relevant (It is a budget light afterall)

I really liked cree’s MT-G2 emitter, so I built my first T10b MT-G2 light a few months back.. But still i felt its too big and not really pocketable.. I wanted to build a light you could keep in your pocket and light up a whole room if you needed to

Received an Ultrafire SK98 (Sipik Sk98 clone) and thought, gee.. if i could fit the MT-G2 in the T10b, why not cram it into the SK98??

So …

The led is HUGE compared to my nitecore SRT5 (ok not really since it has an aspheric lens but still.. :D)

Note : SK98 MT-G2 itself is smaller in size then the SRT5, but weights slightly heavier (due to driver and 2 x imr)

This thing can literally flood an entire room with light, focusing it makes it throw better.. but it the throw beam is still huge, it makes up for it will sheer brightness

This ultrafire SK98 was one of the lucky ones that passed the hollow pill lottery (mine was a solid pill)..

Light is running on a iOS 4.5a 3 mode driver (H,M,L) powered by 2 x IMR AW 18350 cells, and yes, it zooms Big Smile

Guestimate brightness would be about 2,500 LED lumens on high (tailcap about 4~ amps), 1,000-ish lumens on medium and maybe 150-ish lumens on low

On high, It gets warm within a few seconds of using and HOT after about a minute, surprisingly, on medium and low mode, it doesn’t get really hot and on low theres practically no heat

Beamshots!! Note, on the left is my SRT5 on max output (750 ansi lumens), on the left, SK98 MT-G2 fully zoomed out

Merry Christmas all!!

Hi everyone thanks for the welcome Smile

Might be making more of those soon, its hard to comprehend how bright this light really is, and yes it gets hot really fast.. but its still usable, on high mode its really more for shock and awe (or blinding a whole group of people :D), but on medium and low its still ok, on medium its still on par with many other lights on their highest mode (800+ lumens), even on low, its STILL bright enough to light up the whole area in front of you to allow walking (due to its insane flood)

Also, i really like the tint on it, neutral white (for reference look at the beehive photo), although its not hcri but its tint is still nicer to look at, I carry this along with me on a daily basis

I wonder how it would work with a frosted aspheric lens?

Have you modded the switch if not you will never see the measured current.
Have you take some lux measurements…I guess not you will get upset.

I have modded a sk98 with 3 xml2u2 and recognized that the aspheric steals so many lumens…

Hi guys, thanks again for the welcome!!

@Old-Lumens – Hmm dunno but maybe if i can get another sk98 can try taking sandpaper and making a diy frosted aspheric Big Smile

@FlashPilot – You could, but i wouldn’t recommend it as it seriously heats up to the point you can’t even hold it without burning yourself, this thing is HOT

@GottaZoom – Hmm will try taking some comparison beamshots tonight at my warehouse if i have the time

@Illuminaria – Yeah and it burns like one too, shine it too near a wall at high mode and you’ll blind yourself

@cat eyes – I got it from one of those aliexpress sellers, but i think his store was closed due to too many fraud cases, mine actually came after 2 months (the first time was because it got held up at customs, or so they say), the sk98 i receive didn’t even match the one that was posted, his photo had a sharp bezel, mine is slightly curved, which looks nicer imo and the build quality is surprisingly not bad.. i’m still looking for a good sk98 supplier though, will be flying to china in jan to personally buy up all the LEDs, drivers and hosts Big Smile

how about fasttech, 3 to choose from, one might be good

@Bort – Hmm will take alook there.. but seems to have a few SH98 and SK98s, whats the actual difference between them?

@cateyes – hmm even if the pill isn’t solid i read somewhere you could take a copper wire and coil it up until it becomes a copper “coin” so that it fills up the “hole” in the middle

Anyone knows if its possible to include multiple switches in a driver? (eg, one for power and one for mode change) It will also be able to momentary light with that switch

Of course it is possible, but you need a custom driver/firmware. Ask drJones he is smart in this kind of things…

Oh it doesn’t have to be this particular iOS driver, even a standard single cell 3a driver will do too, might want to try a triple xpg/nichia with triple tir optics too Big Smile

i have no clue, i just saw them, in the reviews or comments for the sk98 theres a link to two more lights, i saw them yesterday but i’m not planning on buying any of them so i didn’t look into them in any detail

I guess the problem would be there’s no way to guarantee the light you’ll receive is the one you one, since they’re all so similar.. then you also have cases of hollow pills.. missing screws.. scratches and cracks even before you switch on the light.. lottery?

all chinese lights are a lottery, my defect/failure rate is over 50%, i had started a thread on it a long time ago

Ok just had the time to take some beamshots..

With the SK98 aspheric lens, this thing floods like nobody’s business, i can’t even get the “spill area” on camera.. lens can’t zoom that far out

Here’s my Nitecore SRT at max output (750lm) vs the SK98 MTG2

It looks like the light from the MTG2 is brighter than the building lights would be. That’s awesome. I laughed out loud when I scrolled down those pictures. I would really like to see outside shots of flood versus zoom on your little light cannon.
