KD (kaidomain): Deals and new products thread

Having never built a triple series light… why would one go that route?

mattlward, versus a FET hack reference, thIs in series boost driver provides:

  • Less maximum peak output, we already know that. Our main limitation here is the maximum allowable input current to the driver (10A theoretical) and its efficiency, which rule the amount of power burned in the driver. However, up to ≈25W of output is nice enough for a lot of 1S setups, really enough power to make a compact torch hot fast.
  • Fully regulated modes, no pulse-width-modulation dung, constant output within battery voltage/SoC window.
  • Full battery utilization (down to 3V) with shutdown. In my opinion, we should make aware the developers of these drivers they should use slightly lower cutoff values for high current input drivers, as any little stray resistance can become a serious input burden.

A tailcap FET switch may be advisable.

I want to say thanks. The Problem is solved! KD :+1: :beer:
If anybody can use 1-10 MC-E Serial boards let me know. I do not want money for the boards only shipping costs.
But i think it is only interisting for people from the EU because of the shipping costs.

Hi BanL,

What is the best driver for this particular led? Which is also available in Kaidoman.

Thanks

Too many variables to give an answer without knowing your needed driver size and cell configuration Erwin18.

will the led get damaged with this board : http://www.kaidomain.com/p/S026840.Osram-SFH-4716AS-IR850nm-IR-Emitter-with-KDLIGHT-3535-20-20mm-x-1_5mm-DTP-Copper-MCPCB ? isnt the center pad positive+ ?

this will be nice project http://www.kaidomain.com/p/S026829.Triple-Cree-XP-E2-Red-Green-Blue-LED-Emitter-with-20mm-x-1_5mm-DTP-Copper-PCB-Individual-w-optics + http://www.kaidomain.com/p/S026866.KZ-3016-Individual-Triple-LED-20mm-1_5A-2_7V-4_5V-Driver-Circuit-Board (wish the driver was 17mm and had 4th mode all leds on.)

Thank you for your understanding.

Thank you

You can let me know what is the driver size that you want to have?

And what is your battery configuration?

We have several drivers that is suitable for the CREE XHP35 LED.

You can refer for the search result

Thank you

Instead of pushing one LED to maximum possible brightness (at lower efficiency), or to mix several color temperatures (white) or colors (e.g. far red, red, and red-orange)

@BanL
Today i checked switches on your side. You have a nice assortment, but most of the time i am missing the information if it is a forward clicky or a reverse clicky switch. And that is something that a potentional buyer needs to know if he want that the driver and switch are working together.

Luminus SST-40 at Kaidomain, nice new possibility Ban! N4 is not the highest output bin, but I ordered two for testing!

http://www.kaidomain.com/p/S026881.Luminus-SST-40-N4-BA-White-6500K-LED-Emitter

is this code active?

Compared with xml2 how it performs?

Will other tint bins be available? I have one of these in a light already and they seem ok.

Who knows? Output at specified currents and the thermal resistance are pretty much the same, so the question is what happens if you overdrive them :smiling_imp:

Edit: and if they perform: the million dollar question is: will they dedome?

Very interisting this Luminus SST-40! If i can read right we can use a XM MCPCB with this led. But the low voltage (voltage bin vj= 2,7-2,9V) and the high amps (5amps +) are crying for a regulated driver. With a fet you will probably burn the led to a crispy piece of art. :smiling_imp:

Looks like it could be a good efficiency booster in regulated lights where all you want is an emitter upgrade. I’d be interested to see djozz test one of these. I’d be willing to donate to the cause

Hi TheOnlyDocc

Thank you for your comment.

I will help to update the product description.

Thank you.

My sample is in a Olight. I did pull it out and mounted it to a Noctigon and tested it in a C8 with 6 extra 7135’s. It worked very well, did have a little tint shift as you went out in the spill. My BLF Review. I did find an odd artifact in the beam and it was corrected by PflexPro microtexture lens. The artifact was present in the C8 as well, but not as easy to spot. I have since put it back in the Olight, I liked the tint, but I do not know binning on the Olight led.

Just noticed these. This is great you got them on the way!

They sound very interesting - decent output, low voltage. I see it's the same footprint as a XM-L2, so should be a step up for that foot print in terms of output and high amps. They are rated at 5A max, so hoping they can take 8-10A.

At 700 mA, this N4 bin is rated same as a U2, but at 2 A, it's close to a U3 bin. As you up the amps, the lumens output rises compared to a XM-L2. This makes sense because of the lower Vf. If it can take high amps, and then if it can dedome, might be a winner.

Ban - would be great if you can get N5 or P2 bins! I believe the XM-L2 U4's can fail at ~5.2A, so these should be capable of going higher.
