I dedomed my fw21 pro xhp50 before I sold it a few months ago.

How much was the tint affected by that?


Well, in my case it was much worse, tint changed A LOT


Sofirn SC31 Pro 6500K for reference


I am looking for something interesting to put there

What in the name of lumens is that? Shocked
How did you do that? How much did you slice? Didn’t even know that kind of result was possible.

Oh wow Mocarney! I’ve never seen anything like that !

Put (3) osram CULPM1 !! It would be so awesome, and I wanted to do it. You can buy them bare from Simon for about $27 for all 3 of them. Would be an awesome mod, and they are 4040 footprint so they would reflow right into the existing mcpcb. Perfect opportunity to do it considering what happened to yours.

Thanks for that looks like a simple MCPCB swap if I can get my bezel ring off.
Lumintop said they can sell me the MCPCB for XHP 50.2 so I will order two. Then I can keep the 6500K LED’s on the original board. If I do not like the 5400K as much I can just fit the original back on. I will keep the second MCPCB for future mods maybe.
thx

If you dont mind, what way did you communicate it with Lumintop? I never had any luck with trying to communicate with them. I sold my fw21 pro because i never heard back about them selling me a seperate mcpcb…

Looks like most of the phosphor was scraped or pulled off the emitters when you took the domes off. I learned on this forum a while ago (can’t remember exactly where) that the reason why white LEDs look yellow when they’re not powered is because the diode itself only emits a very narrow band of wavelengths, almost like a laser, and the rest of the spectrum is filled in when that blue/violet light hits a yellowish florescent material. Without that yellow phosphor – all that’s left on yours are those little yellow scraps you can see in the pics – you’re left with nothing but that lasery indigo.

definitely an easy fix once you get 3 more 4040 or 5050 bare leds, just reflow and go!

you decide mocarny which emitters your going with?

The SST40 has a 5050 footprint, the same as the XHP50.2. The 4040s may fit on 5050 pads, i haven’t checked, but it’s not a like for like size swap.

SST40 would be cool, I was thinking of something more…rare? I have second FW21 Pro XHP50.2 and I would like to have maybe something high CRI, 4500K
