the high beam is the one that uses the bottom led that you discovered and that is why it has different power rating Low/High. Its not only the shield that moves.
Tought so but no. Both LEDs are connected in series and are lit up fully the whole time. High beam action is made by moving shutter away exposing different pattern to the projector.

Hi, I just modified my NHK projectors and your tips worked perfectly. I could only add that you could try to move forward whole top mirror, not only twist it right. Move right side the same amount as left side. It really seems like a lot of light escapes up becsuse mirror is set too far back (or LED is placed too much forward) and does not cover what it should.
I tried it without bolts, moving it freely. It is how I got best of it. I think it will be somehow unique for each projector with different tolerances of parts. Different batch of mirrors may need different allignment.
@@75L48 yes, it could be the case. But anyway your tips worked perfectly. One thing is that I distanced the Lens just about half of a milimeter, becsuse I noticed that plastic front cover of my lamp diffuses the light slighltly so I had to take this into account and make my Beam pattern a bit over focused so that lamp would event it out. Could you give you what's app or email? I would be grateful if I could show you what I have achieved and compare it to your projectors. By the way, do you have any footage how it looks after assembling it on car?
@@MrPepto93 Isnt there like a contact email for this account? No video on that yet but I may do it in the future. Anyways I am really pleased with it so far, drove around 50 000km 90% at night since I dont have the nerves to drive in day traffic :) and its just perfect.

I saw this video just after purchasing the NHK Pro Plus 2.5 Bi-LED . For sure I will open them to check the mounting and to apply some thermal paste. Do you recommend using CPU thermal paste like the arctic MX-5 or Noctua NH-D5 ? Do you think it will dry out ? CPU's can go up to 300W so I think it should be okay.
Ive used MX-4 I think.. Chinese use generic white compound that is used in anything from LCD screens to welders. Nothing fancy but it gents the job done.
Hi there. I've placed an order for the NHK V. Can you please tell me the dimensions of the fan (L/l/H)? I want to be sure that I will order the right one, as I can't find the same model that you used in your project. Also, can you please tell me if you experienced with the Osram 30W led chips? I am looking to replace the chips. Big respect for your work and sharing!
Well its this fan PF40281V1-000U-A99, you will surely find dimensions in the datasheet. I still have the car and it still works with original chinese LEDs. If you plan on changing everything you might as well save yourself some cash and buy some no name 40USD crap of which there is plenty. :D
@@75L48 thanks for your time! Also, I will come back here with updates if necessary. I will instal them into the Ford Focus 2 favelift headlights. Don't know if I can keep the AFS function with these lens. I hope so.
Very interesting, cheers. I'm about to buy a 2.5" version of this light because it's the correct size to replace poor standard unit in my car. Unfortunately I cannot find a brand other than the NHK... and wonder how many units I the market are real NHK and others a just poor copies. I don't have the ability to change chips and adjust fan wattage, so it looks like I'll have to just see how it goes.
OEM projectors exist like the ones from morimoto used in some Toyotas I think. Output is much lower though. Build quality should be better. Then there are Valeo and BOSCH parts which exist in their catalogues but are impossible to source. So I guess it is as you said, take it and hope for the best!
Does somebody know about the newer updates version of the V generation? I got myself a pair of projectors and they don't look like the ones in the video. The lens are further away from the body (about 0.2mm), the led chips are positioned different, the body and the radiators are different. Does somebody know something? Thanks.
Thanks for the great video, I would have overlooked all the faults you mentioned. What did you end up dropping the voltage to on the fan? Would the Sunon fan still live happy without dropping the voltage? I had to choose a different fan from Sunon, as the vapo fan is on national back order for quite some time. I purchased a pair of Sunon fans which appears to be its equal, other than the ball bearing design, and lower wattage rating of 6.12W, part number PF40281B1-000U-A99. Is that fan an adequate supplement for the vapo fan you used? Given the lower wattage would I be ok not modifying the voltage to the LM317?
Something around 7V or so.. I measured heatsink temps before and after and even with 7V those Sunon fans dropped temps a bit compared to the chinese crap fans. They just have so much better flow. But still you can run them full power as they are rated for thousands of hours.
Hi bro-! Do you mean that the wind should blow in the opposite direction of the lens? Your review was very helpful. If it wasn't for you... I would have thrown this away. :)
I also had similar shitty output on my NHK V4 (yellow tint and not sharp cutoff line). For now I just only moved top mirror and pushed the lens with rings, without moving bottom mirror (I havent disassembled whole projector yet) and so far so good, but still got some yellow tint, althougth is MUCH MUCH smaller and visible only when very close to wall (comparing with previous shit I could safely say that now I dont have this tint :P). Tomorrow I will disassembly whole projecotrs and move bottom mirror also. And by the way. Do you think moving lens more than you had will do any better? Or moving mirrors a little bit more/less? Have you testet with other positions of mirror/lens? Cheers :)
Hi what generic version of this would you recommend as you say it isn’t worth it for the money which I agree do you have any experience with the generic ones
Man you have some great content and knowledge to share, just wish your camera work was better. Not shitting on you, just constructive criticism. Thanks for the upload
No offense taken. For me its just the matter of getting informations to the people with lowest effort possible. I don't have time nor I am willing to commit hours to make it better. Believe it or not this was taken in one go with pausing record. :) Thanks!
Good afternoon, basically what you said is that expensive biled projector is equal to cheap biled projector? Can you recommend some brands of aliexpress biled? I was thinking to buy a expensive biled but now... How can I talk directly with You? Best Regards
Sorry I didn´t compare them to those cheap ones you can get from 30USD up. However soon I am getting latest gen V of these, thrilled about what they´ve changed, if anything and their light output. Mediocre build quality aside, these light up the roads like crazy!
@@tomeks9504 for now only visible issue is yellow "ghost" on the cutoff line but I think when I will dissassembly the projectors the other issue will also appear.
Nice video bro, i was considering the plug and play NHK biled, but they look like there's no fan on the back... And after watching your video I am not sure if I want them :D What Biled lens do you recommend at around this pricepoint?
Hi Branislav Thank you very much for informative video, I already order 5pairs of IV Plus & 5pairs of Gen 5. can I ask you where I can buy the fan ? Also is it possible to change the Chinese led with Osram or Cree with high wattage if available. regards
Hi, bought at Mouser.com, they ship worldwide. It was this one PF40281V1-000U-A99. What I forgot to mention is, you need to make fan suck hot air from an enclosure. Not blow into it as it was from factory. There is inevitably always some dust and it will be blown directly onto lens. So dont forget to do that also. I dont see why not, LED I shown from OSRAM is perfect fit for this. However those only come in 15.5W I think, thats much less than that chinese one. Would need to try it if its sufficient. Cree X-HP70B with 32W max. would be superior but has large chip area, dont know how it would focus down.
Dobrý deň. Chcem sa opýtať aky je problem s NHK biled projektormi. Uvažujem o kúpe BiLed 5.generacie ktora neni najlacnejšia tak ma zaujíma aké majú nhk projektori problemi. Poprípade čo by ste doporučili na miesto toho. Predpokladám podľa mena že ste Slovák popripade Čech preto správa po slovensky:) Veľmi pekne ďakujem.
Ja mám 2 mesiace NHK IV Plus a je to delo ta 5 ka je ešte výkonnejšia a stojí to za tie peniaze. Odporúčam to dať cez stabilizátor napätia na 12V lebo cez 13,5V už to začne svetelné kmitať (nepríjemné na zrak ) a zníži sa svietivosť .
