[♛ FreemeGB] ASTROLUX FT03 XHP50.2 (3V) 4300lm 735m 26650/ 21700/ 18650 Flashlight - SHIPPED!

50.2 is still going to need a boost driver or no?

No, it’s a 3V XHP50.2.

It’s going to use the same FET+1 driver.

Nice. Should be the same NarsilM firmware as the SST version then.

I am interested in the 50.2. NW of course. CW if that’s the only option. May even grab 2.

Wrong thread, didn’t realise this was for the XHP50.2 version.

Do you know the specific tint they plan to use on the NW? I am hoping 3A tint

Interested for 2 nw

Interested, possibly for 3

The FT03 with the 3v 50.2 is very nice….

I would be in for a few of them…not for myself…friends…

interested in 1 or 2 NW.

Keen!

In for one FT03 XHP50.2.

Let’s see if I understand correctly, the XHP50.2 may have around similar lumens as the SST40, but will have a bit more floody (but smoother) beam pattern than the SST40. Also XHP50.2 may (or may not) have a nicer tint than the SST40?

SST40 at low brightness levels will look a bit yellow/greenish.
XHP50.2 beam tends to have a hotspot that’s cooler and a corona/spill area that’s somewhat warmer.

thank you freeme for my dream

i will collect 50.2 cool white

The 50.2 is over double the lumens of what the SST40 can do because it’s a bigger led.
SST40 die is 2mm x 2mm = 4mm2
Xhp50.2 die is 2.94mm x 2.94mm = 8.64mm2.

The smaller die size of the SST40 means it has a narrower beam angle which makes a smaller hot spot and has longer throw.

The 50.2 has much more lumens (making the spill light brighter), but the extra brightness does not compensate enough to give similar throw. It has less throw distance.

The tint on the 50.2 and 70.2 are always a bit wierd due to their flip chip design. Their coronas are always yellow compared to the hot spot.

The older xhp50 had the same color hot spot and corona which looked nicer, but they had a pronounced donut hole beam pattern in SMO reflectors.

So the 50.2 has the weird yellow corona, but at least the hot spot looks smoother with a SMO reflector. It’s the better trade off. I don’t notice the yellow corona much any more.

I can’t comment on the SST40 tint. I don’t have one.

Will the runtime be the same as the SST40 version?

No, worse runtime.

I don’t know, this is a question of efficiency. If we pick a specific brightness level, like 500 lumen, I’m not sure which will run longer. The 50.2 is 4 x XP-G3 so maybe they will run more efficiently.

On Turbo, the bigger 50.2 will suck up the juice much faster.

About when is the 50.2 going to be available?

I should have asked which will be more efficient at 1000 Lumen.
