Lumintop FW1A discussion and review

Varbos if you’re going to get silly you might as well mention the one variant I’d actually be interested in - FW1A GT, a D1S sized (or slightly larger) thrower with a tail switch.
…but for now let’s stick with what we have. Hopefully I can get my hands on an FW1A soon!

The 21700 variant is already on its way…

who will be the first person to convert their FW1A to a triple with a big Aluminum heatsink?

Daaamn O_O

No FW3B (brass) and maybe FW3BC (brass with Cu head) ?
No FW3A original (1st prototype) ?

That is what tracking on mine looks like as well, not sure that it really means it is in the States.

Mine looked like that as well, and then magically showed up at my home a few days later.

Today was a good day.


Looking forward to more details, especially about the beam. :slight_smile:

Same here. I’m also interested in current draw with the FET.

bmengineer - does this use a 16mm or 20mm star? Thanks.

Good for you, and nice pix!

Anyone know what smooth reflector would fit this? Going to build osram variants.

If assume the same as the FW3A, but I’ll check eventually.

Looking forward to see them :slight_smile:
Had the same idea some days ago! But I guess I will only get one of these in case the Osram doesn’t get “puff” on max :wink:

I also thought of making the FW1A into an FW3A, with a copper pill below the MCPCB, instead of the configuration 1 led + reflector. It would have more mass to absorb heat from a triple :smiley: :smiling_imp:

More mass sure, but also a much worse thermal path. I don’t really think that’s a great idea.

Ahah, I would squeeze a copper/brass rod in the head to “make contact” :smiling_imp:
Although they are a different flashlights, I’ve done it with Jaxman E3, Sofirn SP32 and OTR M1 (all turned into triples), and the heating path is not bad. Maybe not perfect, but not bad too!
But I do get your point :+1:

I’d imagine the copper heatsink on the FW3TC does a better job, and the FW3C almost definitely does.

He said it’s definitely nicer and he likes the design

people have been using spacers forever and the thermal transfer is very good, even with spacers that only contact on the bottom and not the sides.
