Just sent PM for 2 sheets of DC Fix, I have 1 light in particular I wanted to use it on, I think I messed up the emitter (5700k nichia 219c) while reflowing and there’s a ton of rings and a tiny dark area in the middle of the hot spot. Normally I wouldn’t get too worked up over some artifacts but this one makes the light look cheap. 
Hopefully this fixes it
much better, thanks boaz
Thanks for sharing the photos k-wong. Care to share some of the specs on that light? What distance was the wall from the light?
Recieved the dc-fix today...will wait until dark to apply and test. Thanks for the quick mail-out!
It was about 3 feet for a Lumintop ED25 (2xAA) with 219c 5700k. I’d probably do a 4k or 5k next time as it was too close to the original stock xpl emitter and less output. The DC Fix definitely helped with the multiple rings and tint shift but it was also a bit floodier.
Here are a couple before and after shots. Stock Convoy S2+ 3B tint, 16-18" from white wall. Sorry if my photog prowess is not too good but it shows the difference. Much improved beam for my use.

The photos don't really do justice to the expanded spill area the film gives the light. Great stuff!
I bought 3 sheets of this from Boaz. He must have raced to the post office because I Paypaled him on Saturday and received it on Monday. It looks to be the real deal too. Thanks for providing this service Boaz.
@ Boaz, are you still offering this for sale?
This last comment was answered via PM ….
Yes I have sheets of the DC-FIX
As well as a thicker / harder diffuser material (about the thickness of a playing card ).
I also have a film that spreads the beam horizontally that would make for an interesting bike light beam
….
Lets see if we can get a few members who have integrating spheres or light boxes to do some real world testing on 3 or 4 different materials.
It might be interesting to see how close different peoples measurements with various spheres will be … When we get some real numbers I’ll post some beamshots and start putting up some of the other diffusion materials for sale …
Anyone interested in doing some testing …send me a P.M.
Boaz, still using the stuff I bought off you late last year, thanks for still offering it here!
Christmas bump
A little Extra Dc-Fix in every order this holiday season
Boaz, did you ever get anyone to test those ‘other’ diffusion materials? I’m wondering if/when those will be for sale. I don’t have a light box, or I’d be happy to do some testing for you. :innocent:
Got my Xmas bonus pack a few days ago. Thanks!
Have not tried any of the films yet.
All those gifts and packages must have really slowed down the mail .first class mail usually takes a day or two for only a couple hundred miles .
thanks for the reply let me know what you think
happy new year
Just placed an order, better and faster communication than I have ever experienced.
