Funny, it appears renamed to “GreatLED Store”.
I forgot to mention the carrier is modded., will post photo tonight… I just want to know if Sony vct5a are safe with sst40.
Ok here is my fenix tk75 quad sst40 dedome. Is Sony vtc5a safe to use in this light?
It’s possible you will blow the bond wires from too much current (~9.5A) if it’s direct drive and low circuit resistance. What is the voltage configuration and driver? And have you used other cells in the light successfully?
I think Newlumen’s light is modded by Vinh , with “driver vnx2” which is a fet driver .
I would use VTC6 to be safe…
Ask Vinh. He usually uses VTC5A…
Yes sir. The tk75vn is modded by Vinh. Probably drawing 4.5 amp from each cell… the Carrier is 4S… I like using Sony vtc5a. So far I have no problem using the highest mode with my vtc5a.
Either way, if the light break, he said he will fix it for free… so I don’t worry much…
It draws about 8-9 amps per cell .
Please advice from those who bought SST-40 from Aliexpress store called GreatLED Store, that it was called Shenzhen Great Technology Co.,Ltd.
How was the LED performance ? despite the problem of bubbles in the dome
i want to use this led in general lighting so what i care about is its performance in producing a lot of lumens
Anyone knows if there are higher bins available somewhere? Thanks!
I think I read in Richard’s thread that he asked about other tints/bins but that Luminus thusfar only made a few types at all.
I ordered two from there. I couldn’t make out any flaws in the domes of the ones I received. I put one in a direct-drive light. I haven’t done any rigorous tests, but I can say that it puts out a lot of light and runs relatively cool. I built a similar light in an F13 host, with a 26650 battery, but I used an SST-40 emitter on a DTP copper MCPCB I bought from Kai domain. I’d estimate they have similar performance, but the one from KaiDomain is slightly warmer, as expected.
KD has VH Voltage binned SST-40’s now.
Has higher brightness bin too.

SST-40 was already an efficient LED. Now this should be even better.
If you don’t burn it out. 
Yeah, it really deserves a proper regulated driver.
Or a proper small battery in a small host. 
I was searching the web just a few days ago for a higher bin SST-40’s. This must of just popped up. Good find and thanks for sharing. Ordered 4 
I have just used SST40 in my BLF A6 light, but instead of using INR Battery i used a normal Samsung cell I pulled it out if a laptop battery and i got more than 6 amps on turbo and of course a lot of light, So my question is will it burn if i used INR Cell ?
And have any one successfully dedome it ? Or IT should be sliced like the XHP family ?
Any dedoming or Slicing Advice ?
Well, I sliced down an SST-40, lost lumens and no net gain in throw, and beam pattern/tint is worse. So from my experience, I would not recommend, but who knows if I did it wrong. Haven't slice much LED's but an XHP70 I did came out well.
