Thank you for your ordering.
Hi BanL
Will it be possible to make this driver with a 17mm board?
http://www.kaidomain.com/p/S026606.H1-A-20mm-3A-1-cell-5-Mode-Boost-Driver-Circuit-Board-for-Cree-XHP50-6V-MT-G2-MK-R2
Im trying to get more info on this driver - http://www.kaidomain.com/p/S024906.FX7-17mm-2_8V-4_8V-3A-5-Mode-LED-Driver-Circuit-Board-(1-pc)
Hoping someone has used this driver and would be able to give us first hand information.
Current: Max. 3A
Lo : 300mA @ 4.6V
Med : 1200mA @ 4.6V
Hi : 2900mA @ 4.6V
- Interesting why amp rating is measured at 4.6V.
- Is it possible to do a resistor mod?
Presume a worst case scenario. Most useful input voltage value to make an output measurement is, in my opinion, the smaller voltage at which it still can maintain regulation. With an XM-L2 at the output most 7135 linear based drivers will maintain regulation at least down to 3.7V, and if PWM frequency is too high the voltage figure for mid and low modes will be even higher. Of course this is not based in 7135 regulators, but I said that to put this into perspective. That driver may not be able to stay regulated within an usual loaded li-ion voltage range (3 to 4V). This is how I believe we should teach these fellow testers how should they proceed. Thus, to answer your question:
Current is measured at 4.6V because the driver is a PoS and cannot stay in regulation below that voltage. Done.
Cheers ^:)
I sort of get what you are saying Barkuti, and thank you for the explanation.
It is supposed to be a regulated driver and yet it will struggle to do just that at the typical voltage range of a li ion battery.
Not exactly that, glide 1. That thing sort of pissed me off a little bit, I find it misleading. For a linear driver like that, I'd prefer to see the figures for ≈3.7V (or the minimum input voltage at which it keeps regulation -specifying the driven emitter-) and maybe somewhat below to see how it evolves.
This is not to say that 4.6V figure is not useful, it may be a useful figure for those aiming to use 4S Ni-MH input at the driver. Even in such a case, I'd complain because I always want to see worst case scenario figures, which for 4S Ni-MH would be below 4V.
Accepting those figures would be like accepting Ben Johnson's Olympic 100 Meter final record in Seoul, 1988. Sort of. 
Hi
CREE XHP70.2 P2 1C White 6000K to 6500K is available and only US$10.99
http://www.kaidomain.com/p/S027059.Cree-XHP70_2-P2-1C-White-6000K-6500K-LED-Emitter
Thank you
Any plans to sell the driver separate from these new P60 drop-ins?
Hi
If you interested in this driver, you can send to our sales@kaidomain.com for further details
This driver has two version. Once is with 2500mA to 2600mA and you need to have a better heat dissipation.
Another once is 2000mA, that is the version installed on the current P60 drop in.
Thank you
Hi
New batch CREE XHP50.2 5000K arrived to KD
Cree XHP50.2 K2 3B Neutral White 5000K LED Emitter US$7.29
http://www.kaidomain.com/p/S027073.Cree-XHP50_2-K2-3B-Neutral-White-5000K-LED-Emitter
and more other XHP50.2 bare LED are available in KD

Thank you
K2 from non-cutter store? Sounds like a deal!
Keep the new stuff roll'n KD!
If you could please look out for SST-40's in higher bins, and lower temps, like 4000K-5000K. I got in 3 of your SST-40's - will be testing them soon! Everyone who has used them got good results.
Yes! I would like to see the higher bin SST40’s also! :+1:
I would like to also request Higher Bin XHP35’s E4+ and Colder Tints 75000-8000k if possible please! I have purchased many of the E2-1A’s HD’s for de-doming, best tint so far 5200-5000k, no yellow, a very nice neutral white. Would like to shoot for something around 6000-5700k de-domed.

They also have Vf bins.
The lower the better i would say.
Wut? What's Vf bin? I only see N4 listed for SST-40's: http://www.kaidomain.com/Search/SearchResult.sst-40, and in the specs, looks like N4 is the middle bin:
http://www.luminus.com/products/Luminus_SST40W_Datasheet.pdf
In the PDF under the flux bins it says “Forward Voltage Binning Structure”, and it ranges from 2.5 to 3.3 Volts (!).
But i see now it also says: “Individual voltage bins are not orderable”.
So never mind then… :zipper_mouth_face:
Just have to hope to get a good one. The VJ bin KD has is pretty good, with VH being the only one better. A higher flux bin with a lower voltage bin will be more efficient.
