ps edit - actually the chinese name 银锭 aka silver ingot already tells us so. Just that the English “Yinding” doesn’t tell us much. lol :money_mouth_face:
Is it similar to the SFT40 in terms of intensity? Wow….seems to be so from this testing. I’ve always thought that the SFT40 is just a bit lower in intensity but more lumens vs the Osrams.
Either that or my measurement of the Haikelite HT50 is a bit flawed. lol.
New light from Haikelite HK05 with 5pcs SFN60. No reviews yet, “just” 440pcs purchased in past 30 days as of present data….so it should have been just released in the past week or so.
Dang it…… just rmb 358 or usd 53. 5 pcs of SFN60. Suspect real output should be in the rough ballpark of the JKK76, really depends on how it is driven so nobody knows until it is tested out. Total emitter area of the JKK76 is 101mm2 with 7pcs SFN55 while HK05 is 87mm2 based on 1st page data, based on emitter area alone, relatively speaking of coz.
Has PD as well for charging. 充电功率：充电5V 3A，9V 2A，华为SCP5V 4.5A，双向快充。
NW Chaos was 318rmb, while JKK76 was 428 initially before it rose to rmb 538 but coupons from 1 seller can bring it down to rmb 500.
76mm head, 550g mass without cells. That’s +10% mass from the JKK76, which is good for heat at least for the first turbo…but then this might be offset by the smaller total emitter area (theorectically slight efficiency hit relative between the 2?).
Dang it…….3000k, 5000-5500k and 6500k options available.
Of interest also is the individual button head conversion. Convoy wouldn’t sell this separately, so…
9.9rmb for 3pcs.
Fogofwar, what are you waiting for?
Dang it i really don’t need another of this kind of light, even at 5000-5500k.
Just watched a newly posted review on the JKK76, SFT40 vs SFN55.2.
4:32min thermal kickdown for the SFT40, 5:32min thermal kickdown for the SFN 55.2 version. In its 5.5k lumen 4th level setting. That’s a good 20% difference. Too bad no lumen tube or even ceiling bounce to confirm that both are doing same OTF lumens, actually doesn’t even have to be the same level as we can always account for that afterwards and things aren’t perfect in the real world.
Of coz there are many variables that can affect this and no temperature measurements were done for that, some might even call this data pretty useless esp since the SFT40 has so much smaller die area and output are not verified to be around the same on a meter, but it is what it is without actually buying the light and testing it out properly on your own ….draw yr own conclusions coz different strokes for different folks.
Not me in the video………
Note : Not that really technically accurate to compare on vids (vs a meter, any meter……even if it was a phone’s light sensor and ceiling bounce). But then again our eyes in reality are even worse than the video comparison method.
Have a suspicion that the HK05 is 20-25k range, but really need someone to at least ceiling bounce it. Unfortunately lumen tube/box figs from China is not gonna happen.
HK05 with 5pcs SFN60
Manker MK38 with 8pcs 50.3 HI
The same fella with his various Manker MK38s if you want a comparison since the 50.3 HI is not that common
which of these LED cell is the best model sfh43, sfh55, XLamp CXB1830 LED and is there a better model LED cell available than those here in 6 × 6mm size LED cell and who manufactured the sfh43, sfh55 LED cell
is there a model LED cell similar to those in 6 × 6mm size that is up to 15000 Lumens on LED cell that I can use of the 20 pcs × 15000 Lumens so I get in 300,000 Lumens in total with LED cell
does anyone know who manufactured the sfh43, sfh55 LED cell because I want to know
Does anyone have any info on the SFN55.3? The Nightwatch NS73V2 will be using these and supposedly it will be 3000 lumens brighter than the V1 with
the SFN55.2. Not sure I believe the output claim but if true that’s kinda nuts as the V1 is already really bright for a single cell light.
is there a model LED cell similar in 6 × 6mm size that is up to 19000 Lumens on LED cell that I can use of the 20 pcs × 19000 Lumens so I get in 380 000 Lumens in total with LED cell with eutectic technology LED with 200w total comes with 20 pcs Eutectic technology LED cell chip so I can make new custom model LED Cell Chip with 36pcs LED squares on LED Cell Chip with 3V 72A
That currently does not exist, and I don’t think it even could…
6x6mm is even smaller than the usual XHP70 footprint of 7x7mm, which means even if such an LED existed, you’d be challenged even more thermally speaking.
I have a SFN55.2 reflowed on a dtp board, and the plus appears connected to the thermal pad. Did I do a poor reflow or is this a design feature? (like the Oslon Black Flats back in the days). If they are really connected, that ruins it big time for modding, I hope it is my poor skills
