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

Despite some claims from various sellers, for below BBL tint for 2700K, 3500K and 4000K SST-20 leds (I measured quite a few now), I have seen for each colour temperature resp. the same tint every time, for 3500K and 4000K slightly above the BBL, 2700K on/slightly below the BBL. So I wonder if Luminus actually produces anything different, and would be surprised if Neal comes up with a different tint.

I have some 3000K from Hank which turned out to be HB4 (above BBL). I also have some from KD which were listed as HD2 (below BBL). HB4 is yellow, HD2 slightly less so but still yellow none the less despite supposedly being below BBL.

I just found this thread. I smiled when I read the part in the opening thread about No Logo. It was the tipping point when I decided I wanted one. I HATE my life being used as someone else’s billboard, so I avoid logos whenever possible. Then I see in recent posts they put a bunny on the button. It looks good as far as logos go, but now I don’t want one. I have enough flashlights anyway, I’ll live without it.

If someone managed to source those bin the light would look like a red laser pointer on turbo.

You might have missed it (easy to do with so many posts recently):

oh, sweet!

There is a catch though when using the led in a reflector light or with narrow TIR: the light ending up in the hotspot is for the greater part formed by light emitted at an angle, which tends to be closer to or above the BBL, compared to the cone of light straight above the led. So you must start fairly far below the BBL to end with a hotspot that is still not above it.

Chiming in again as it appears I haven’t been added yet.

Add me to the list.

You weren’t added to the list because the last update was before you manifested your interest in the flashlight!
When the list is updated again, you will see your name.

Great! :+1:

Cheers, after I posted I double checked to see when the last update had happened and it was a couple days prior to my previous post.

Oh well. That’s what I get for posting before my morning coffee.

No problem :+1: :beer:
Keep checkin, but note that updates may take a while to be done!

Please remember my name as well. I definitely want one!

Not really. Djozz already answered with most of the reason why, but there’s also something to be said for rose-tinted glasses. If we actually got the requested bins, it would still not be as pink as people like.

I find the regular duv units a bit awkward, since they’re so small… so I generally use mduv instead — thousandths of a duv unit. Anyway, most of the LEDs we use range from about +5 mduv (cyan/green/yellow) to –5 mduv (magenta/pink). In studies though, they found people preferred about –15 mduv (very pink). So they’re actually considering changing the definition of ANSI standard white because its “pure white” line is so far from what people actually prefer.

( I want a bunny on the lens too for cool wall shots!)

Kind regards

More than +/- 6 mduv is not ANSI white and some metrics of white light, such as CRI become invalid. Examples of ANSI non-white LEDs seen in the flashlight world include the Nichia 219B sw45k (–7-8 mduv at modest current) and the “90 CRI” XP-G3 Olight used in the S1 Mini (+10 mduv on its lowest mode).

The study is really interesting because it asked people what light looked the most natural, and what they picked is extremely rosy and hypersaturated. I like rosy and saturated, plan to put three sw45ks in one of my FW3As, and light my room with a Viltrox VL200T, but I recognize these light sources differ from unfiltered sunlight.

First of all, a big thanks to all who have been involved — this is a really nice light and I am in for at least one on the group buy. Being a relative newcomer, I am grateful for the opportunity.

That said, I will probably buy one after the group buy as a present for somebody who was born in the year of the rabbit and who would greatly enjoy having the logo, at least if the price delta is not too great (i.e. “the bunny price”). :wink:

Finally, I am somewhat surprised about all the commotion over what I consider minor changes. The essence of this light remains consistent and anyone who has been involved in product development realizes that changes are inevitable. The only way to get exactly what the initial concept proposed is to have a custom build at a much higher price. As soon as a manufacturer gets involved, there must be changes made to fit their process and also to insure adequate sales volume to recover startup costs and ongoing manufacturing.

Please add me in for one extra light… thx

I find all the bickering and “threatening” to not purchase hilarious. It’s got a well-loved open-source firmware, a good range of fully-regulated power, a standardized LED layout and optics, a novel rear e-switch, and it still manages to be basically the second-smallest 18650 light in current production. At $30, I’d buy it if they painted it plaid; we’re lucky it doesn’t cost three times that much.

I’m already down for one, but put me down for a second. I’ll probably buy at least that many. If nothing else, they’ll be fun to tinker with or make good gifts.
