Which FW3a LED did I get this time?

Bob_McBob · 2019-09-24T15:23:01.000Z

Top to bottom:

219C
XP-L HI
SST-20

Aw crud. I either have to suck it up and keep a light I didn’t really want, or return it AGAIN and see if the shipping dude can get it right a THIRD time!

How hard is it to swap emitters between FW3 heads? Since I want my TK models to be Nichia, I’ll either have to swap drivers or re-flash, right?

Reflowing isn’t very difficult even with a basic hot plate or frying pan, though the Lumintop MCPCBs have a rather soft mask. You’ll probably want some solder paste. If you’re talking about 219B, flashing the firmware to a lower output version allows you to safely use any cell you want, but as long as you stick to lower current cells like NCR18650GA the stock firmware works ok. You don’t need to change anything for 219C.

However… the seller should be sending you the correct light, express, or providing a partial refund. Two wrong lights in a row is unacceptable. The knurling damage is also rather unfortunate.

If you need everything — It’s a lot easier to order a loaded MCPCB with the LEDs you want from Mtn Electronics —that is if he has what you want

I was referring to swapping the entire emitter (and probably driver) assembly from a light that has the right setup. Yes, this would mean I’d have to buy a different light with a Nichia in it, but hey - look at the crowd I’m in. Having another ‘spare’ light with a different emitter would not be a huge hardship.

Where did you order it from?

If you got a new MCPCB with the right LEDs on it, it is just two wires that need to be unsoldered then resoldered. Pretty standard stuff for the most part if you are comfortable with soldering. If you’re wanting 219B’s, you’d have to source them and put them in yourself anyway. Definitely follow the above advice on protecting those emitters with the special firmware or lower drain battery if you do though. I think there is a post around here with some for sale if you go that route.

Sorry - I’m not throwing a vendor under the bus while the situation is still open. Now that I know what the situation is, I’ve opened a conversation about it.

All I want is the stock high CRI Nichia that they come with stock. Nothing fancy.

You know… it just struck me. I have no idea which XPL-HI color temp this might be. That straddles the border between Annoying and Nope.

Lightbringer · 2019-09-24T16:41:16.000Z

Hmmm.

FW3A LED type/color selector?

Tally-ho · 2019-09-24T17:06:18.000Z

Ordered @ nealsgadgets a blue anodized FW3A SST20, received 219C :

Scallywag · 2019-09-24T18:06:53.000Z

I wonder if places like Illumn are checking theirs. I hope so, though I imagine it’s a pain.

f0xx · 2019-09-24T18:43:42.000Z

You guys have me curious… how do I tell the difference between the 219Cs and the SST-20s? Looking at the first post, I don’t see much difference between top and bottom.

EDIT:

looking closely, maybe the dome is bigger on the 219c?

The Nichia seems to have a darker square surround while the SST square surround looks whiter.

Yeah, looks like it.

It appears my SST-20 is an SST-20. I like it a LOT, just wanted to be sure in case I order another one down the road.

I recently purchased a used NS22 to use as a host for a quad — the seller thought he had a SST 4K but it ended up being more a 3K (he hated it ) —- I already had a 4K version plus I purchased 35 / 4K emitters —- this light was way warmer and rosier—Go figure I like it

Yes, very easy to differentiate once you know how they look like. Have a look here : LEDs & Other Stuff - (Reference Guide)
8th column, raw 4 = SST20
8th column, raw 5 = 219C

amishbill · 2019-09-25T06:41:55.000Z

Would a loaded MCPCB like this Samsung 351 or this Nichia be a direct unsolder / resolder exchange?

Are they typically a glued in or just held in by pressure from the optic?

chops728 · 2019-09-25T11:38:13.000Z

Yes a simple change out—— I put the Samsung in one of mine

amishbill · 2019-09-25T13:34:06.000Z

Thanks guys.
Now comes the hard part - deciding on my path.

- return/replace and be done with it?

- some store credit, keep the wrong light, and maybe try to put the right LED board in it.

keep the wrong light and take a deeper discount on a Ti/Cu hybrid…

amishbill · 2019-09-25T14:26:42.000Z

Besides the lower CRI, what are the practical differences between the 5k XPL-HI and the 291C / SST 20?
