Jasonww on the other hand likes cool white and doesn’t notice low pwm .. both of which make me crazy.



My previous experience with very yellow NW lights has put me off from them. I have come to find 5700K is okay (xhp70.2 and xpl).

I put a Nichia 219C D280 80+ CRI 5000K behind a 60° pebbled TIR in a headlamp and really like it. Except for the lower output. For headlamp use I need good color rendition. I sometimes have to identify wire colors in automotive use where CW is not the best choice. I might try a SAMSUNG LH351D 4000K 90CRI LED in a headlamp. I don’t think I’ll loose much output and maybe get even better color rendition? I hope it’s not yellow! Lol

Also, I guess I’m lucky I don’t notice PWM. Party

I have yet to find anyone on BLF with my particular preferences.

If you don’t want it to be yellow, get the LH351D in 5000K.

This is a commendable effort!

About the FW3A, mostly just waiting still. I hear Lumintop wants to adjust a part by half a millimeter, and needs Fritz to update the CAD model… so kinda just waiting on that.

Even though it’s the lower 80+ CRI?

My problem is that I don’t know anyone selling this led on a mcpcb. I can buy the led from MTN E and the mcpcb from led4power, but I can’t put them together (reflow). Do you know of anyone selling this combo?

Arrow sells 5000K 90 CRI. They don’t sell it on an MCPCB though. It does work on XP/219 size MCPCBs.

I’m not sure what to suggest other than learning to reflow. It does not take a great deal of skill or special equipment. Here’s a demo of reflow with a lighter. If you’re concerned about breaking stuff, Arrow has cheap LH351Bs and you can test for functionality using a lithium button cell and a couple wires.

Didn’t Mountain do custom reflows?

If not, I may be able to help. PM me.

It’s too much hassle. Maybe in the future MTN will get some 4040 mcpcb and make things simple.

The LH351D is a 3535 emitter.

It is? I wonder why MTN doesn’t offer them on a mcpcb? I might have gotten this led confused with the Luxeon V.

I’ll ask MTN if they sell them on a mcpcb. It might just be a glitch that the website doesn’t show the option.

They just recently, I believe, started selling them in two flavors:

I think Arrow Electronics also has the 5000K, 90 CRI of both the LH351D and the LH351C.

This is weird.

You lot are already talking about modding the thing, that does not yet exist.

Very peculiar. Trust the team involved (well, some of them), and lets see where it goes.

After then might be a time to discuss.

Hum, despite I get your point, and despite trusting the team, I guess we may be talking about modding this before the FW3A is completed/ out for sale/ delivered.

Even this is my specific case, and even if I don’t know how it will look with the XPL or the LH351 emitters, I am sure (well, 95% at least) that I will probably mod it with Luxeon V emitters just because I love how they make the beams look!!

Brainstorming about modding is something that may even help the FW3A Team to get some nice things on the final version of the flashlight, be it UI, look, internals, emitters…

And, again, being a fan of this project despite delays and all the stuff involved, I trust, appreciate and thank the work done and to be done! Thumbs UpBeer

LOL, modding discussions of lights that do not exist are one of these things that I like about BLF Big Smile

Of course people are talking about modding it on BLF, whether it exists yet or not. That’s what we do here.

And given that it’s a FET triple with Carclo 105xx optics, there’s sufficient information to predict the results of most potential mods. I’m sure I’ll be modding more than one of mine because I’m sure I want one with SST-20s, and there will probably be more emitters that interest me.

Tom Tom, please stop telling everyone what to do or not. I see it in other threads also.

Thinking and talking about possible future mods is one of the reasons for many to be here.

Also, not to be confused: the interest and discussion about modding this light means that it will be MORE successful as a product, not less so. We don’t want t omake (or buy) a light that is difficult or impossible to mod. Although, we do sometimes get a light made that is close enough to “right” for everyone that few ever do end up modding it. Some still will, and it’s good that they can, and that they want to! Wink

With all of your history with this forum it’s your statement that seems “very peculiar”

I’m thinking about modding at least one of mine too. If I can get some 219B emitters, I think I’ll put those in it. They’re my favorite, and they work really well in a 10511 which has had the frosting polished off.

I have a triple 219B here sitting on their CU-PCB.
And I am a bit afraid not to fry them in a FW3A. Do you plan to use a -20% version of Andúril?

No, but I would set the ceiling to the highest regulated level, and I doubt I’ll use it above that level much.

The 219B has a higher Vf than 219C, which makes it harder to overdrive. OTOH, it also turns into smoke at a much lower current. But I’ve had FET-based 219B triples before and haven’t had any issues. It’s 219C which really runs into problems on direct drive.

I don’t plan on giving it a hot rod cell either though. Something with more mAh and less current suits my use better.
