Just for completeness’ sake, i’ll just post some other chinese LEDs here as well, though limited info.
Bro fogofwar, do you have any info on these G type LEDs?
G50
Used in Haikelite HT50, 72mm head, has AR coated glass even, on a truly cheap budgetlight! I have a copy and as posted in other threads, it does hit the advertised numbers of 6k lm and 500k cd when measured and compared against other well known and well measured lights, like the BLF Q8/Sofirn Q8.
Got it at rmb 195 (usd 29) before the price increase. edit - just realised banggood is selling at usd 60+
I’d have gotten 2 of this and get > 10k lm + 1 mil cd if not for the fact that it isn’t particularly easy to aim 2 such tight hotspots together in real life.
2pcs of JKK76 SFN 55.2 version is, of course, a totally different story
1.1km distance from a 60mm head diameter reflector. 5000 lm.
I don’t have this one so no way of verifying the specs. If this were 4 * 18650 / 3 *21700 and bigger diameter 70mm head like the HT50, i’d consider as it’s still cheap (current TB prices and how much the sellers wanna profit based on demand)
Reviewers mentioned no green tint at lower levels.
One fella mentioned the tint used in this model seems to be even better than the imported SBT 90.2
Believable or not, up to the individual. I think worst case scenario it should not be that bad.
Thanks for sharing, good read, the ones used in the HT50 is most probably is not the same bin/tint that dojzz got or something, or maybe they have made improvements recently.
edit - read farther down the thread, the ones other received seems to be much better.
Anyway, the ones used in the HT50, the CCT is high of course (well above 6000) but in all modes there is no hint of green. In fact way better than my other established brand names stuff, like my Jetbeam RRT-2 with its XM-L, which would kill tint /CRI purveyours.
I have used my HT50 as ceiling bounce illum, wierd i know….but it does have a pretty decent mass and size, so @ 1-2k levels it’s pretty efficient for longer term usage.
I paid nearly usd 100 for the Jetbeam RRT-2 XM-L around a decade ago! And the magnetic ring selector isn’t working that well now. :person_facepalming:
A pic would tell the story better. LHS is my Jetbeam RRT-2, RHS Haikelite HT50. Lowest mode in the HT50 (4 settings + 1 turbo), not sure how bright it is though, never measured on my meter. ps the RRT-2 is like 30-40cm closer to the wall than the HT50, in an effort to make the hotspots to be more similar in size. Actually there is sort of a moonlight mode on the HT50 (long press from off) but it’s just as white….coz for comparison’s sake there is no low low mode on the RRT-2 for beamshot on wall pics.
Yep the round ones, were referred to as the Yinding projector LED on this site. However, I think Yinding is just the reseller, and we don’t who the actual manufacturer is.
People have found it to produce an excellent beam shape - tint is hit or miss though. Overall, it is similar to a Luminus SFT40 or San’an SFS80 in terms of lumens and intensity.
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.
