I’ve put a 95 CRI SST-20 in two different lights that originally had an XP-L HI. One was regulated, and the throw was the same. The other, an Astrolux SS has a FET driver, and both power consumption and throw increased. I get 434m (47 kcd). This light has a larger head and reflector, so I’d expect more throw.
1250lm is a fair bit more than I get from 5A, so I imagine those numbers are for low-CRI. I’d expect over 1000 lumens and over 500m from high-CRI though.
Received SST40 and XHP50.2 and 2 21700 tubes. Fast shipping, 8 days! Very nice lights. Just slightly smaller than a C8. Head OD is 3mm smaller. SST40 tint is nice, looks more white than blue to my eyes. Thanks for a great deal.
I received mine with the SST-20W 95CRI 3000k. The host is beautiful. Love the functional cooling fins and color. The beam is very tight and measures 638 lumens at 1 sec. The only negative is that it doesn’t tail stand. I wonder why they didn’t raise the ears a tint bit to allow tail standing.
You know you have too many lights when you don’t realize you already bought this last year:
With that said, they are slightly different tail switch/driver/UI/anodizing but they do lego.
A couple observations:
My light didn’t turn on at all when I first got it. I did some troubleshooting and found out the tail switch was not making contact somewhere. I took it apart, put it back together and tightened the retaining ring a bit more. Started working. I know this was the problem because the light worked when I used a wire to bridge battery negative and the tube.
Anodizing/machining is acceptable considering the cost but it’s nothing more than OK.
I could be wrong on this but UI seems to be as follows (SST-20 3000K): low/mid/high, double click turbo (5.1x amps measured at tail), triple click strobe
The SST-20 3000K seems to change tint noticeably when in turbo which seems consistent with maukka’s test of the 4000K , seeing it in person was a bit surprising
Ofcourse I know double click for turbo. I was expecting lumens to be higher too and I tested it with serveral different 21700 VTC6A, 40T, and 30T and got the same measurement. If you don’t have the Maukka calibrated lights, I suggest you get a set because you will be surprised how much lower real ANSI lumens are. I had to scrap the hundreds of previous measurements I made prior to my current TA tube calibrated with Maukka lights.
I know about the DUV shift a long time ago. I have over half a dozen lights running the SST-20W 95CRI 3000k from Kaidomain. DUV drops significantly with higher output. This is actually pretty typical for all emitters. I see the same with 219B, 219C, LH351D, Oson Square, Cree emitters, etc. That’s why for me I rather get the rosiest bin possible in multi emitter lights because I usually use my lights at lower outputs for efficiency and at low output, even 219B 9080 or 5A/5D tinted lights are at or just below the BBL for perfect neutral tint.
Hey, fair enough. I didn’t even measure I just guessed it would be closer to how the 4000K measures but I guess you really do lose that much going to a 3K bin.
Got mine with 3000K SST-20, and get a bit over 600 lumen on “turbo”. It was an impulse buy and although the build quality and led choice is very nice, I’m not really sure if it adds a lot to what I already have (but then, what other flashlight does do that?).
At least the SST-20 is doing its thing, produces a very attractive beam and at low mode in the hotspot I measure 97.8 CRI, R9=88, 2960K and duv –0.0008. At higher modes the CRI is slightly lower but with rosier tint.
I’m still trying to figure what the merit is of extreme CRI in a throwy flashlight
