Where to get genuine xhp70.2 led chips?

Flashlight Modding and DIY Parts

Hi! Im very beginer in diy led stuff and im going to build diy led bar thing for my car and I chose xhp70.2 chips, I would be using 5 of them.

But the problem is, where do I find genuine ones, I live in eu so eu stores would be great, but aliexpress probably the best one, so many different ones but how I know which is genuine?

I have searched this forum, and I found link for great ali store that sells real ones, but they are only 6v and I really need 12v because the lower current.
This is the store https://convoy.aliexpress.com/store/330416?spm=a2g0o.detail.100005.1.1111622364ONei

Try Kaidomain, or just buy mcpcb and get really original and properly marked leds from Farnell , Mauser, Digikey , RScomponents and so on

Thanks for the reply, is Kaidomain legit site? Trustpilot gave it pretty low score

Sofirn also sells them! https://sofirnlight.com/xhp702-6500k-p0061.html
I can’t really attest to this particular emitter, but the other ones I’ve gotten from them (LH351D and such) have appeared genuine.

Thanks for the replies! Very good to know different sites that sell these kinda things!

However, I was wondering, could I run those 6V chips 2 in series, so they would accept 12v voltage?

I have read that those LEDs can be “overclocked” with more amps to give even more lumens if you have the cooling. Would my idea work, I was planning to power them with 12V/10A for one “series” so would that be like 10A for each led chip (when I have 2x6v in series).

I’m planning to water cool these with pc components and put them in my cars front grill, and where I live its –20’C in winter and so goddamn dark, so I think that would be plenty of cooling when driving 80km/h and –20’c air flowing trough the water-cooling radiator

I think it’s totally fine to run the emitters in series (as long as you have enough voltage to drive them), so you will either have to use 4 or 6 of them in pairs.

As far as “overclocking” the LEDs go, I think 10A should be plausible, but of course the efficiency and lifespan will take a hit as usual.

Since you live up the north, I think you should consider 4000k CCT or warmer for best visibility.

I have bought 6 of these for the reflectors: https://www.aliexpress.com/item/32964481744.html?spm=a2g0s.12269583.0.0.1dc09739Tu8krJ

And 3 of these, if the beam is too wide and I will probably use these for like 3 of the 6 I was planning to install to get like “spot” and “flood” in the same light: https://www.aliexpress.com/item/4000728475986.html?spm=a2g0s.9042311.0.0.33914c4dZg8Zg2

For driving them I was planning to order these, as you can change the max voltage and amps : https://www.aliexpress.com/item/32845683864.html?spm=a2g0o.productlist.0.0.335c51499zwWlv&algo_pvid=02b5d544-e81e-4b2c-90b2-7c7e01451a23&algo_expid=02b5d544-e81e-4b2c-90b2-7c7e01451a23-29&btsid=0bb0623d16065661374758353e97f2&ws_ab_test=searchweb0_0,searchweb201602*,searchweb201603*

Thank you for this information. That 4000k or warmer, was really good to know, I haven’t done any research how color temperature affects the lighting in different conditions, will definitely do warmer as now I know its superior in snow rain.

I was driving like 3 days ago in horrible snow rain and visibility was like 15meters, probably because I have I think around 6500k xenon lights in my car at the moment

the whiter the light the difficult it is to see as the whiter reflects back to your eyes from the snow storm

also simon from convoy on aliexpress does xhp70 leds ,

maybe you will also need some kind of cooling or a driver that has thermal protection so the hotter it gets the lower the output

ive seen some xhp70 allready made for car lights, h7 and h4 sockets. but they are a all in one thing, with a cooling fin on the back and a little fan, (these dont last long and usually melt)

anyway how north are you ? where abouts in finland ???
