this is obviously not news... but just went to light-reviews.com to check out those Quark reviews: Quark 123² Tactical and Quark AA² Regular, and glad that i have similar runtime experience (compare to selfbuilt's reviews here: 4Sevens Quark Round-up Review, guess when you win some, you lose some).
I didn't pay much attention to the runtime for first 2 sets of batteries on my 123² and >10 charging cycles on AA², but now I know why I keep getting the feeling that the 123² just keep running and running, above and beyong the rated 1.8 hours (mine was ~20 minutes each run for 9 days), while the AA² just barely touches ~1 hour instead of the rated 1.3 hours (guess they could be using 2500/2700mAH setup).

my Quark's food supply:
feeding Quark 123² Tactical with 4Sevens' CR123A batteries,
feeding Quark AA² Regular with Eneloop 2000 mAH LSD batteries

can get b4 x'mas?

can get before wednesday? coz ill be away from wednesday

Thanks susuman, now waiting for it to fly over here and distributed !
Hope can get it before Christmas

Wooo, so many excited RRT-0 touched down! Let's do the dance!!





Heya, I need some education here hee . Where u get ur info on T1.5 and T.2.25/G4 socket? Stumbled on your thread in CPF, and a little similar like you, got interested in incan not too long ago And for longer use/runtime, my fav EDC is the Quark AA too (tactical) Incan's just for that momentarily wow feeling + 100 CRI itchy bitty bug

It's like the "weekend" car..


I use the medium mode most on my Quark AA and I still don't have to recharge my 14500 so often What more with 123^2, runtime on it is excellent. The build for the Quark series are just okay only, but their efficiency is promising.

I certainly hope can deliver all by Christmas, but I cannot promise.

I hope they will ship on Monday, and arrive on Tuesday, normally in the afternoon, then I will notify you all.
For those need to post, I will POSLaju it as soon as I pack it, then will deliver to post office, but if over the final time of posting, then it will count as Wednesday, and hopefully will delivered to you on Thursday.

Those need to collect it, it will be at my office, or tumpang someone to collect it. Other place pls contact me, but I am stuck with office most of the time.

This is ideal flow, I try my best to make it up, but if any thing got stuck, please understand and patient, haha, I am sure you have many lights to use on Christmas even without the RRT0.

I now really respect OldNewspaper had done so many GB, its really not easy.

Luckily you guys pay little more, or else even run into currency/conversion loss , I really noob in doing the GB.

That is why I said the most correct way to calculate run time is by wattage if the voltage is diffrent
2 unit 3V CR123A (Assume 1500mAH) wattage (power) is
2x 3V x 1500mAH = 9000mW or 9Watt

(what AA you use?, assume 2000mAH rechargeble (AA Alkaline should be more or less 1500mAH-2000mAH))
While 2 unit 1.2V NiMH 2000mAH
2 x 1.2V x 2000mAH = 4800mW or 4.8Watt

so you can see 2 AA is only half of the power of 2 CR123A

KISS = 2 CR123A primary is double the runtime of 2 AA 2000mAH rechargeable

well explained. yup, for all things equal, the Lithium CR123A primaries may give approximately twice the performance... but it gets more complicated when taking into account other variables (Vf? temperature? cell resistance? etc... ) wasn't trying to compare the different batteries chemistries tho, I'm just pretty impressed by the efficiency of Quark 123² circuit.

hey, do post some pictures of the RRT-0 when you have it. especially the warm one

Haha, that's a special run of LF2XT titanium with sapphire lens and Cree XP-G from Steve Ku.
I'm waiting for 'official' XP-G release from LiteFlux next year, hope the neutral white XP-G will be available in time to make it.

old newspaper, any idea when will the teleforce head be available for the VX Ultra? This little sucker is bright but it would be even better if it's throw capability is enhanced - that'll be AWESOME!!

ok, i vote for another GB for D-mini Ultra and also the teleforce head!!

Can postpone to next year ah? Then i can save some cash haha. But poor old newspaper, i think u should get a bit of profit lah so that u no need so susah. So much trouble for us. but i think everyone really appreciates it.

looks good but i like the liteflux design better. the tritium on the tailswitch is nice though.

yala... i tarik balik my quote.... i requote...

i vote for another GB for D-mini Ultra VX (for next year) with the Teleforce head and also for oldnewspaper to earn a little bit profit for the upcoming GBs..

how abt we pitch in n pool together some RMs

so oldnewspaper can get the D-mini VX Ultra Teleforce on us

how much is the D-mini Ultra VX Teleforce anyway....? US30?


anyway I commited to

01-damonlbs - RM20


dont mind add urself to the list



ps' i got the idea from MYCPF old threads

1. damonlbs - RM20
2. ggMing - RM20

It was easy to tell the difference between my Fenix LD10's High and Turbo. Also easy between LD10's Turbo (est ~90L) and the Inova T1 (100L)
*All L are OTF, some estimated.

But the higher it is, it's probably harder.


123^2 runs a buck only circuit and is very efficient. That's Y I love this head over all the others especially if you run only Li-ion.


You... evil...

Looks... so... good... dang...

Surefire goodness or NOT, the older style single stage mode E1L with KL1 head. Bought it 2nd hand & carried it for a few days and it is rather a disappointment to me because this is not very bright enough for me. No WOW factor here.

Anyway here are some photos taken during my lunch break.





Sorry, white balance of my camera way off.

Oh by the way I want to sell off this light + 2 almost new surefire batteries for RM300. If anyone is interested, pm me.

Hey man,

Looks good.. That Surefire is nice for a EDC. If I had the cash, I would definitely buy it off ur hands.

What is the output of the KL1? I cant recall.. Maybe I might check my account...
