Jerommel I left a link. There is photos of original driver too. It is Qihan DC GU5.3
YES!
about led driver for head flashlight. Custom boost driver with micro-controller will created by lampman’s helper. It is really difficult to do it in real. He will sell it for 30-50$ per 1 pcs. It will be about 95% effective.
Agro excuse me, but I will never do led bulbs with ordinary “white” leds, only lamps for plants! (even it is more cheaper with w/$ and lx/
Because ordinary “fake white” LED’s spectrum is NOT HEALTHY! And my lamps must work years, even if no - it is easy to repair it, and some one can start use it not in the shed or laundry room
I can’t find it, sorry.
But it’s very interesting to me, i love the idea of a super CRI COB headlamp.
I’m not having very good luck here. I ordered a Sunlike bulb on Nov10, about the exact same day Mauka’s shipped. It only has two tracking events, one for “acceptance” on Nov13, and one for “processed through facility” on Nov19. That’s it, it’s been a full month now since the last tracking update. I requested Adam re-ship with the promise I would send a second payment if they both arrived. But he wants to just wait 
It was just one bulb for trying out and deciding how many to actually order…
Do not worry, you are not alone =)
There is another poor fellow because of cheap ukrain post.
Next step will be in USA, but it can track today or after some days or years =)
As I said, I will never use ukrain post again! Never! Now I am in belarus (BelMORDOR)
Looks like some sort of post loop within Ukrainian territory, isn't it? :facepalm:
Of course no idea what those character strings mean, and can't copy/paste them in a translator.
Looked like it. After uploading the images to Yandex Translate my suspicions were confirmed.
It is mean that parcel already outside ukraine, but still not inside USA. Transit from one to another country.
Nah, forget it. At first I thought the right side image was a tracking continuation of the left side one, but now I see it isn't.
So you complain because of 5 - 6 days of time just to leave the country. Wellp, it works and is cheap. That's good.
Concerning COB led related questions, the other day someone shared a SOL1306SXX datasheet with me, where I could see an Vf of ≈34 V and 180 mA of driving current for the rated power. This is fine but there's no datasheets, links to datasheets or any other information of this sort in your site, this is important for anyone aiming to drive these leds. Is the typical Vf of these COBs around the same number?
Thanks. 
Usually buyers ask me about characteristics if they can not find datasheet.
I add voltage and maximum current to the names.
SOL and SAW is almost the same. Voltage just a little lower in SOL, but current is bigger.
And what about the higher powered emitters? 12 and 25 W I mean. Do they scale up just in current, i.e. same number of in series crystals? 
Yes, just current. Double quantity of crystals. It is 12S
Lol that is probably mine
Any news on my order yet?
As I said, it will be not fast. I will received 2700k SOL 6w leds after ~1 month. It is already in my warehouse in China.
Okidoki. 
New year, same old tracking data. The shipment was last seen November 19, 2019.
No. 1.1.20 it is in the usa customs. Just check tracking number
Oh I see wrong number. It is from Belpost what was sended 23.12.19 already in USA. Your from ukrpost still no =(
