I’m no expert but I don’t think this is right. It seems this optic sits too far down into the MCPCB since either the optic legs don’t have a big enough “shelf” and/or the MCPCB holes are slightly too big.
Sitting on the flat granite I can slightly rock the optic back and forth by the two optic legs but just barely. It’s basically just a thin sheet of paper shy of straight up resting on the MCPCB. In two of the MCPCB holes there is almost no rotational play so it probably wont shear a dome but I feel like it has a decent chance of crushing the substrate or not being in the correct focus?
MCPCB is 1.6mm high (listed as 1.5mm) so that probably doesn’t help either
Had the exact same problem, the optic rests on the dome meaning that the optic cuts into the domes when it’s installed with any pressure on the optic. Lost 4x XP-L HI’s finding this out.
I have built a few triples with Kaidomain optics and i always shave the legs so the optics sits flat on the MCPCB? The triples are deep enough to fit over the whole LED?
If you already have the optics over the dome and its done no damage there should be no problem? you can only apply a very limited amount of pressure more once tighten.
I tried the Kaidomain optics at the stock height looks similiar to your left pic and the beam is wrong its all wonky.
On the domed LED’s its still resting on the LED itself and the pressure will cut into the domes around the bulge. On the XP-L HI’s it just sliced the phosphor off the package.
I think it’s the same 2 legged quad optic used on the S41/S41S
. I remember changing a bunch of them S41/S41S into triples because the optic sat on the LED pad and crushed the pad. Also when you tightened or removed the bezel you broke off one or both legs and sheared the domes off…sumtin like that…IIRC…
I guess the “return” section of the website is just for show. I submitted one over 2 weeks ago but no contact or further instructions.
No acknowledgement in this thread of the issues either. Can’t say i’m surprised based on past posts but in the future I will refrain from ordering new products and let other people be Kaidomain testers.
It doesn’t even say to send it back much less where to send it. I don’t see an address listed anywhere on your entire site and no one has contacted me so I don’t know why you are thinking I would have shipped this back for more than I paid.
Return #289 and #290
If the products don’t fit together you should remove them and take it up with your mfg. I’m not shipping unsellable product back.
Feel free to correct me if these products are good and let me know how they are supposed to be used.
