FREEME ✌ ASTROLUX FT03S SFH55 9300lm & FT03 SFT40 2200lm 1300m NarsilM v1.3 USB-C - ALIVE

I figure it will measure brighter since it’s a very high drain battery, but I wouldn’t think you’d see the difference with your eyes - compared to a decent high capacity cell like the Shockli 5500/Keeppower 6000.

What are you comparing it to?

Battery length/spring compression should not have a noticable effect. Pretty minimal. The dual spring design makes it minimal. If it were a single spring then compressing the coils until they touch acts like a wire bypass and reduces resistance.

Frankly, I would not concern myself with pushing the amperage higher on this light (like with high drain cells). It’s pretty close to the limit as is.

I looked at HKJ’s comparator at the Efest 4200. The 2016 model looks like this and is pretty comparable to the Ijoy high drain.

The 2017 version looks like this and is a bit weaker. I think Efest has stayed with this for 2018 as well (HKJ has not tested a 2018 version)

So I don’t think your running a super high drain battery, just a regular high drain. It’s not putting out the big voltage at a 10A load like the Ijoy, Aspire or Golisi. So it’s probably fine.

Still, the SST-40 is a pretty new led so we don’t know how long it will handle these maxed out levels. Might be fine in the long run or might burn out. No one knows. :wink:

i am running that efest 4200mah in my light and no issues so far.

Has anyone measured the throw of both the SST40 and XHP50.2?

FT03 SST40> 898m (previous reading)

FT03 XHP50.2(3v) > 729m (taken today)

eh xhp35 ?

Whats your cd number for the XHP50.2 edition? Is it close to my 174kcd?

729 meters = 133kcd

(729 x 729 = 531,441 ÷ 4 = 132,860)

im confused, why talk about xhp35… this light has sst40 no? i dont get it… whats the throw on sst40 ? jason help me

I think he means sst-40, not xhp35-HI. A lot of people got about 900 meters from the SST-40 version. Check the title of this thread.

Maybe Freeme unintentionally confirmed an upcoming FT03 version with XHP35 HI ?? :smiley:

Doubt it. More like he was thinking of FT02. There is no reason for a xhp35-HI version FT03 when the FT02 is pretty much that right now.

(Edit, The FT02 is 10mm smaller head diameter 59mm to 69mm and a 21700 battery, but still pretty close to FT03 size)

On a sidenote.
The FT03 is a nice looking and nice performing light, but it still feels light and cheap though.

That’s heaps low i would expect more.

Any one tried a XPL-HI in these? Probably a similiar result as a sliced SST40?

Correction: it's SSt40.

The 50.2 is a chunky emitter not known for throw. It’s a lot more light, but not as much throw.

I think the xpl-hi IS about the same size die as a sliced SST-40. The SST-40 might be a little brighter. IDK if anyone has done the swap. Surely someone tried.

Personally i would compare the throw of the XHP50.2 to a XML2 yea not great but not the worse plus you get the extra output over what the XML2 has. Because of the flip chip design it performs better than the standard XHP50.

Anyone knows what is the exact bin and tint of the 5700k XHP-50.2? Thanks!

You could use an 18650 and lead sleeve to make it “feel” higher quality.

Seriously though, weight is just thermal mass (which is definitely good for the xhp50.2…) but anyone who takes a midsize thrower backpacking will likely appreciate the light weight.

I never understood where the heavier = better quality came from.
