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

Setting aside the fact he used a mode that’s FET driven (meaning that alone could cause variation) I got similar results when I did no lens vs UCL.

I suspect the integrating sphere is getting more light bounced back into the sensor when you use a glass lens vs nothing.

Weird. It looks like you’ve tried a bunch of lenses. Which one would you recommend?

Which size ucl lens fits the fw3a? I don’t have calipers to check the dimensions.

I think it’s 22.61 x 1.90 mm

I just realize you are talking about the nichia 219C as Lumintop desn’t offer 219B option, which is what I was comparing to. The SST-20 FD2 is definitely better than any 219C I’ve seen. The 219C is greenish just like the SST-20 FB4 tint bin. The only rosy 219C are the “E” bin ones that Clemence sold in the past but I haven’t seen one in person.

Actually the 4000k 219c that come’s with the FW3A is pretty rosy, I have both 219c and the 4000k SST-20 version.

The 219c def alot more rosey and looks to be slightly whiter, higher kelvin possibly.

But I still perfer the SST-20, cause stays cooler and throws further and also has a pretty nice tint, like some one mentioned before its almost like a slightly whiter Halogen bulb tint.

Both variations have good tints.

I added a low output mode. MUCH more green on low output. This tint on this emitter varies more than the average emitter relative to current.

Texas_Ace lumen sphere calibrated with Maukka calibration lights for lumen measurements
Sekonic C-800-U for photometric data. There are much cheaper alternatives out there but I think those require connecting to a computer but I might be wrong.

See Contactr’s response. Also I started with fully charged batteries, after multiple tests, the voltage drops which will also affect output. Heat will also reduce output. UCL glass lens will not increase output over no lens but they are suppose to be the best lens available with the claimed 98-99% light transmission.

I found out about the UCL lens from Contactr’s post. He posted the dimensions. This dimension also fits the Wuben TO46R and TO10R. Dropped the DUV in my TO46R modded with Kaidomain SST-20 3000K by roughly 0.001 to 0.0015 in all output levels resulting in more negative DUV and nicer rosier tint.

Did you compare the 219c and SST-20 on turbo and 219C is rosier? If so, that is absolutely amazing as I think the 219C has higher output also but lower CRI and R9 value. I wonder if you just got lucky with the tint lottery or did Lumintop source the “E” bin 219C. I haven’t heard any reports on the 219C tint in this light besides this. If they turn out nice, I might have to buy one.

Negative Duv at 100 lumens? Either I got 2x crappy SST-20’s or the 10509 is working magic.

oops! should be positive. fixed now.

are all copper versions in stock at Neal ? anyone got shipping notice how long after order paid ?

Haven’t received any shipping info yet. :frowning:

After lensgate, I decided not to go through with an SST-20 variant order I had placed, since I got a XPL HI variant from the first batch. As offered by Neal, I requested a refund and received it in full within a day. I contacted him through forum PM though, maybe that made a difference.

okay weird, mine shipped like a day after with shipping nr, the sst20 copper version.

What does not help attracting what you call appropriate responses is repeatingly calling Neal (who has been around on this forum for years) “this guy”. Further, this is an internet forum so you can always expect some responses that are less than thoughtful, it helps to not to get too upset by them.
Mind that Neal did a lot of good things in the development of flashlights for BLF so that is why “this guy” has quite some credit over here. Unfortunately communication is not his greatest talent but he is doing a better job at that than some other chinese sellers and at least he shows many good intentions.

I may have saw it at one point and then forgot… What is the CRI for the XP-L HI 7A (WW 3300K) emitter? I bought a 7A light in the group buy.

Do we know the order code for the emitters so I can see it on the datasheet?

Guessing E7 or F7 kit?

What voltage bin?

The 7A is 80 CRI, as 3000K Cree leds are all 80 CRI minimum. It would be a first for Lumintop to mention order codes, I have not seen one.

Ok, I wasn’t sure if 80, 85 or 90 since I see all of those available for 3000 and 3250K if I’m reading the datasheet correctly…

At this point, your comments are just provoking the forum.

most orders were shipped in the past three days

some US orders and DHL express orders will update the tracking later.

a few orders will ship this week.
