FW1A Pro - replacing emitter for more throw

Hi Flashlight Experts.
I want to swap out the XHP50.2 emitter to one that offers more throw without changing the driver.
I am considering these 2…
XPL Hi
XHP35
Will either work as plug and play while maintaining the current driver?

Neither will fit the MCPCB (it’s of 5050 footprint and these emitters are 3535). If you also swap out the MCPCB you can use the XP-L HI (it’s a 3V emitter just like the XHP50.2 that is in the stock torch while the XHP35 is 12V).
I’d just get the FW1A non-pro with a XP-L HI.

What if I swap out the whole MCPCB with one that has XPL Hi on it. Will that work with the existing driver? Thanks

You can try to switch emiter to sst40. It does not have same intensity as xpl-hi, but much higher output compensates this issue. It is probably highest throwing 5050 led.

Yes, but not with the gasket (the thing that keeps it aligned with the reflector).

If you are going to change the MCPCB I think you can go with CSLPM1 or CULPM1. Buying from convoy, CSLPM1 has better BIN.

Simon has new emitter on his ali store! SFT-40! 3v 5050. From what I can tell, it has similar output as sst-40 but more throw due to no dome.

Xpl hi would make it a plain fw1a.

Xhp35 is the wrong voltage.

So imo osram or sft-40 is your perfect option.

Be reckless and take a chance on SFT-40. I bought 2 waiting on shipping. I believe in luminus

I forgot about SFT-40.It can be reflowed on original MCPCB. Not the best BIN tint, but no the worst either. Actually it’s the only available I think :D.

Thanks for all advices.
I will probably get a CULPM1 and SFT-40 and try them out.

i ordered fw1a with xplhi and w1 from simon. im goingto try swap led. when i do that i will write it here.

What is W1?

It is the OSRAM KW CSLNM1.TG (1mm2) Led.

Thread reference: OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

Ok. Thanks for the info.
I thought CULPM1 would be a better option?
Anyway, I’m unable to find emitter for CULPM1, so I ordered for SFT40 instead.

Put an osram in it! That's what I'm going to do once I buy one again lol

i thought throw was more about the reflector, than the driver/LED

I think that for turbo is better to go with 2mm2 osram. 1mm2 tops out around 4A-5A.

So to confirm again, the original driver for XHP50.2 in the FW1A Pro works if i swap in a SFT40 or CULPM1 mcpcb? Or do I need to swap the correct driver as well?

I read you were having trouble finding CULPM1, Here is the link on Convoys store,

Either one will work. CULPM1 will have to be bought on mcpcb and make sure to ask Simon for proper led gasket

Ok Thanks!

I have done it.
FW1A Pro with CULPM1.
Now waiting for the smooth reflector to arrive.
The original mcpcb is 3mm thick.
So i double stack a bare mcpcb below the CULPM1 mcpcb, both 1.5mm.
Btw, the original body is from the stainless steel FW3A/FW3S.
P/S…I had to file the edges of the 20mm CULPM1 mcpcb as the original diameter of the mcpcb is 19mm
