FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Whatever, I’ll swap the LEDs anyway…
But I don’t see how the price would be the same between XP-L HI and SST20…

Thanks for the update tatasal… :+1:

QingMing Festival this year is 5 April 2019 by the way. :wink:

I ’thought’ the XP-L HI was gonna be around $6 more per light. :question:

From the OP:

Sorry guys…
Well, it’s a clever move from Lumintop.
Begin to produce the long awaited FW3A with XP-L HI, sell it for 36$ to evryone would can’t wait anymore after all this time…then you eventually put some SST20 in the production and sell more for 30$…

I don’t think Lumintop is trying to do anything “clever”. It has been known for a very long time the XP-L HI was going to possibly cost around $6 more per light. It has also been known the other LED options have been, for whatever reason; hard to source.

FWIW, the QingMing festival is on Friday, Apr 5 in 2019.

I wish I was as naive as you are, the world would seem like a better place.
Anyway, at least it move forward

Nice! I got mine too :smiley:

Not for me, i’ve been using a 4000K SST-20 for the last week or so on the low modes of a biscotti 1400ma driver and while it is immediately a bit green my eyes adjust within a few seconds of use (even with sunlight through windows as background lighting) at which point it just becomes a joy to use, sublime even (see what i did there :D), with no noticable tint just very useable light with great colours and depth perception (because of the green i think) which is exactly what i want.
In fact it’s (at least temporarily) put me off rosy tints, but that’s for another thread.

For this thread - i’ll be choosing the SST-20 4000K version :slight_smile:
Edit: Although from above it seems this is not confirmed as an option yet :S

Not wanting to delay any further but I was under the impression production samples were to be sent to a number of membrs for a final check over prior to full production commencing.

I wouldn’t put it past any manufacturer to structure availability to maximize profits, but that’s not what’s going on here. Looking at prices on Arrow, the cheapest XP-L HI is $3.50 in bulk quantities. LH351Ds are as low as $0.70, and single quantities of the popular 5000K, 90 CRI version are cheaper than bulk XP-L HIs. A search on Octopart finds the SST-20 in 4000K, 95 CRI is cheaper still, both in single and bulk quantities.

It wouldn’t surprise me if Lumintop’s per-unit profit is actually higher on the lower-priced high-CRI version, whichever emitter it ends up with.

It is a great light! really small but powerful as a 18650 light!

I didn’t read through the thread, how is the heat sink?

Something like that. But the discussion is over there, not here. :slight_smile:

I think it’s interesting, and I’m watching to learn from the thread, but it’s not really for my benefit. I just figure someone on BLF probably has the answers this person needs to make a cool shiny thing.

*eyeroll.gif*

Not every imperfection is a sign of foul play. In this case, it’s probably our fault for not making a decision about SST-20 sooner… or at all, really. They’ve had the XP-L HI in stock for a while, waiting for production. Meanwhile, we told them last-minute in a wishy-washy way that they should maybe offer SST-20 too, and it takes time to get the parts.

Mostly, I just hope the samples are perfect so production can go ahead without any delays.

The heat sink is small. It is not meant for extended use on turbo. The turbo level is mostly just a burst mode. The main goal of this light is not to be bright, the goal is to be practical for daily use. So it is small and ergonomic, instead of big and blindingly bright.

Just because you get incredibly annoyed by green doesn’t objectively prove anything about what others, such as myself, will think of what we perceive as yellow, when we are using low modes - which is only going to happen much indoors, if in an urban area, because I’m not sure if you noticed, but urban areas are brighter at night than less populated areas, and you need to drive your tiny floody 3 emitter light a bit harder if you want the light to shine very far, considering all the competing sources shining in your eyes. So you’re going to be moving towards the rosy end of the spectrum the more current you drive it with, and between that and how even gray urban concrete doesn’t seem to highlight the differences as much as a white wall, I think the average person won’t be too concerned about it. Regardless of what either of us think, the fact that we disagree illustrates my point that people’s perceptions differ and everyone must simply be aware that there isn’t complete agreement on the subjective particulars.

I’m a tint and CRI snob too, but the human eye and brain are pretty good at adapting to just about anything. The longer a period I use a rosy light, the less rosy it appears and the same is true for greenish ones. Ambient light has a HUGE effect on how I perceive the duv and color temp of any lights too.

I understand… :+1: . But actualIy I’m not that “naive”… I’m just not paranoid to the point that I think there is a ‘bad guy’ waiting behind every bush to get me. They are actually only behind a few.
The key is knowing which one’s…… :wink:

Interested, albeit probably a year or two late… :stuck_out_tongue:

What’s the maximum regulated output from the driver? I guess it’s FET driver?
