dual switch
Crop that photo and that's a sweet avatar! 
Looks great Steel! Dual switches makes the UI a lot better right?
So you have installed MELD-X in the Skilhunt DS10, the Fenix E35UE, and one other? What is the third light?
Wow, looks impressive!
Use the correct IC 7135
Finally,
I can see what is “dim to red”
Assembly process records, a lot of small details………

Wow! Such intricate work! 
Great work! Lots of great fabrication!!! 
Nice :+1:
Nice work all of you guys
I’m impressed
I hope someday to make my flashlight as i want.
I’ve read this thread again and again and i have some questions but first thing first what host to use for my requirements?
- First of all IPX8
2.18650B first preference or CR123 - RGBW and UV
- Adjustable output
- Strobo,sos,beacon,police etc
- Easy to use and to make as my first flashlight.
tterev i think 3,4,5,6 is easy with MELD-X 
For 18650 hosts I can recommend the Lumintop SDmini, Solarstorm SC02, Fenix TK16, and the Olight S20
I’ve designed MELD-x to facilitate builds like these as much as possible, but be forewarned, nothing about a RGBWUV build is easy! These are tough installations, I will help as much as I can but I wouldn’t recommend tackling it as a first build.
I agree with the SC02, i have see your project.
What PCBs i would need for this project.
I found some LED’s it’s OK?
RED: XQERED-H2-0000-000000301 630nm
GREEN: XQEGRN-H2-0000-000000B01 535nm
BLUE:XQEBLU-H0-0000-000000Z01 485nm
UV: LHUV-0400-0500 400nm
WHITE: I don’t know about LED and MCPCB some recomendation’s?
I have some soldering skills and equipment if that is the problem.
I appreciate your help.
Depends on what your host and beam pattern requirements are. In general I would recommend XP-L
tterev the 400 nm UV LED is recommended but have you ever try to install 365nm?
I haven’t done 365nm but I have put 380nm parts in a few builds. The only potential issue is that the shorter wavelengths have a greater chance of causing the optics to fluoresce and also may be blocked more by the optics.
After reading about this driver i have to build a light with it. I have a few MC-E Leds left over from my last build so i want to use one MC-E for the job. If i get it right i only have to stack a second 7135 on each channel to get to the 700mA for the MC-E. That should be no problem. But now i have to find a nice (chep) host (dual switch prefered) and single 18650 would be nice. If someone has a tip or maybee a old host to sell let me know (the SKILHUNT H02x or H03x is not a dualswitch light but it would be my favorite light if i can get a used host cheap and if i can fit in the MC-E).
How much would it cost to send the driver without the 7135 + shipping to Germany?
The nitecore ec21 is a nice dual switch host. Fenix makes one as well I think.
International shipping is generally about $5 for untracked (first class envelope) or $26 for tracked and insured (priority international)
Thanks i will send you a PM (with further information) when i know whitch Host i will use. Not sure for now. But i will 100% take one of your drivers!
Now i checked out a few UV LEDs for curing glue (385nm is needed). Did anybody know something about these 3 LED´s? Or maybe is using them and can say if they are good. Or if there is a better one that did not cost 3-4 times the money please let me know
I am close to order but still have a question.
I will probably use this host: https://de.aliexpress.com/item/Dual-Cree-XM-l-U2-Led-Torch-2-x-Cree-XM-L-U2-2-U2-5/1987840494.html?spm=2114.13010208.99999999.262.VuHBZ5.
Is it possible to get 700mA on the white, blue, red and green channel (for the MC-E LED) and then use a FET on the UV channel to get direct drive for ~3-4A (LG UV LED on tripple DTP board)?
Not in the stock configuration, but you should have no problems making those modifications - stack extra regulators on the color channels and replace regulators with a FET on uv. It shouldn’t cause any issues with the rest of the driver as long as the high uv current doesn’t droop the voltage too much.
