I use 85-277v led drivers.
But when I add reusable fuse, I marked it like 220v on the body. If for USA, I add 2 times bigger fuse and marked it 110v
it is Qihan. dimmable marked 185-277, but I use it for 34-36v output only while it can give 65-68v, so it can work with 95-277v or lower voltage
I just added voltage option on web-site
MORDOR is territory what was CCCP, because there is a lot of orcs =)
I already done led lamp for Maukka. It is awesome.
3030 sunlike (new 6v) I will use too. I already draw pcb board for it 22x22mm 2S3P
Yes, Qihan produces good quality LED power supplies (I also use them in some projects), but selling to the EU market you should also think about adding LC filters at the AC input (Qihan has also CE certified power supplies with filters but unfortunately much more expensive).
you mean violet spectrum? Yes, it is all with violet. But I also bought some SOLs w\o violed spectrum for lamps for nail extension jobs, because some gels can polymerize in some situations with violet spectrum.
Also who manufacturin SOLs leds do leds for plants, I am going to do bulbs for additional light for plants. Spectrum is like sunlike + UV + IR
That reminds of something I have to say 
Guys, I'm pleased to announce I successfully arranged some shipments that are already travelling as we speak. So we'll have in the coming weeks new results from tests:
- Lightning Arena has sent some of their CRI97+ bulbs
- SunLikeLamp has sent a very interesting multi-emitter bulb
Thanks to all parties involved! Both reviews will be carried out by our dear maukka. Stay tuned!
CE from qihan not so good. Low power have no models with voltage and current what I need, 20w CE flashing more than 20% because they have PF: 1
I added supressor and reusable fuse and thermistor. Its enough.
About CCTs.
The most popular is 4000k, I also use it. Another is 5000k (2-3 times lower) and 3000k (2-3 times lower than 5k)
it is completely upgraded v 1.3 and 1.4
it was v.1.2 upgrade
Sorry, I will answer here. I will not create topics yet. Now loaded with work and household chores.
I found the 2800K version of this from a Finnish online store and will report back when I get it. The manufacturer told me that this bulb is about to be discontinued though and I couldn’t find the 4000K version for sale anymore.
Heavily modified Qihan drivers I guess.
Supressor? Fuse? Thermistor? 
I added input capacitance to a bunch of Qihan units I had lying around after reading a report of high mains output ripple by some fellow from Mordor or thereabouts, :-)) too. This is a QH-40W-LP with 3 × 15µF (cheap) capacitors:
Let me also share a photo of a 20W “Dark Energy” driver I bought from eBay, which came with good input capacitance:
The above unit had no components on the underside. And I couldn't find sense resistors above either, my guess is they are under the transformer.
It is good 20w led driver. I used it 4-5 years ago in lamps for plants. 25P model. But 600mA disappeared from sale. After that I moved to 20w led driver from Qihan =>22P
About ripple.
There is 2 types of led drivers from Qihan. 1st have no ripple (pulse) in out. This type only 5-20W
2nd is led drivers with good power factor (~0.97). There is only one way do do it not ripple - add capacitors in out.
I tryed to add big capacitors 400v - it was some fatal errors.
The good news, that 80 and 100w models strobe only on 7% (100w 35v)
I mean this
But I also upgrade it to this (old version of upgrade - 1.2)
Where are you guys finding these very handy looking Qihan drivers? eBay and AliExpress didn’t return results that look right.
No actually I don’t prefer violet spectrum for my needs as I’ve tried a few. I’m only looking for some to replace my current household lightbulbs for nighttime use. I prefer 2700K with a negative duv or below the Black Body Locus tint. I’ve tested many bulbs in the past and only the GE Reveal offers this combo but they keep burning out. Their reliability is the worst I’ve ever seen.
They're easy to find, at least for me, with a proper search on eBay. I'll make it easy for you, check this (300mA,350mA,600mA,650mA,900mA,1500mA) led driver custom search, you'll find plenty.
Wow that is some massive output capacitance! Am I seeing the driver came with 8.8mF (4 × 2.2mF), and you added 3 × 6.8mF = 20.4mF to fix the ripple? LoL!
What's wrong with adding high voltage input capacitors, the power factor goes down? 
What he means by Duv is “Delta uv”, or the distance the CIE coordinates are from the Black Body Locus. You likely have never been asked that before, but on BLF it’s a huge deal to many users. Above the BBL is a greenish tint, that disgusts some people. And below the BBL is a reddish “Rosy” tint.
For me, a “rosy” Duv isn’t any better or worse than a “greenish” Duv. But some people need rosy.
Not fix! But do it lower
Just try, and will say what happened 
If everything was so simple, think I would become so bother?
Yes, they didn’t ask. I do not know what to answer …
I think you did, it’s in your reports:
And here it is plotted in “ColorCalculator v7.73”
This is about as green as the sun. But from other threads I know some members consider that unbearably green.
Heck, another member mentioned about a month ago they were trying to get the BBL standard lowered because they thought they had research supporting their claim the BBL itself was greenish. But that research seemed to be using “Fake White” RGB lighting.
I bought for test leds from SOLs manufacturer. Without violet. It is vita white and original white series.
SOLs
I hardly doubt it is a galvanic isolated driver (propably some kind of flyback topology) so in this circuit this inductive component works more like coil/inductor not transformer.
