DC-Fix Diffusion Film Sale

Hi, I was wondering if you still have some DC-Fix left? I’d like to try some on my C8. I tried diffusing it with plain printer paper over the lens; it works fine, just the fact that the output is decimated… :slight_smile:

I have tried matte sheet from an old LCD screen, it had 2 kinds in it: slightly matte and very matte.
Works as expected, but eats Lumens.
It’s probably because there’s space between film and lens.
So i’m interested too, but i’m in Europe so shipping costs might ruin the idea of buying from Boaz.
But maybe you could send a couple of post card sized pieces in a normal envelope?

Anyway, PM sent.

no problem …it’s simple to ship and I still have a bunch left to send out to anyone interested …PM sent .
Thanks /

Just to clarify: the advice is to spray clear coat on a reflector, not on a lens. The clear coat will make the reflector scatter the light a little more so that the beam is more even. For a lens, it’s probably better to use a high quality diffusion film like DC Fix. Another way to remove some of the Donut hole is to move the reflector just a bit out of focus. But, that will also reduce throw, possibly quite significantly.

Clear coat seems to work in a similar way on the lens. The sole reason I was recommended clear coat was because it will diffuse less than DC fix.

I’ve found the main effect of defocusing the reflector is a smaller hotspot with larger corona.

Well, since you’ve done it, I’ll take your word for it. I would have thought it would make the lens ugly and probably the beam too. :confounded:

Before DC-Fix , some people used Glad Press-and-Seal plastic wrap .

In my experience , DC-Fix eats more lumens to the eye than it is reputed to do .

It can really affect throw , in some cases virtually eliminate it .

I only use it for really ringy or artifact laden beams or headlamps or flashlights intended for close-up use .

You can remove it from a lens but not from a reflector.

None the less, good idea to use clear coat.
When you let it ‘rain down’ from some distance it will cause orange peel effect.
Maybe matte clear coat is good too. (?)

Thanks for your PM, Boaz.

Thanks Boaz! PM’d and PP’d. Now I just need to wait for its arrival… :smiley:

I use dc-fix on my throwers, it does not destroy throw, just turns them into normal lights with a good mix of throw and spill. I don’t like throwers. Put it on a normal light, Zebralight SC5 say, and it would indeed kill the throw totally, not a good idea. I bought some from the US via CPF, and I am in the UK. It was probably the same person as the OP. I still have plenty left.

Aloha Boaz,

If you still have some sheets available, I’ll like to purchase 4. PM me and I’ll PP you.

Aloha Mkduffer PM sent …Dc-fix sent today .

EasyB Like I said I think you should try a small dot of diffusion film right in the center of your lens . Try maybe a few different size dots starting with like a paper punch size up to a dime .I was pretty impressed how nicely it made some really bad beams and still kept the hot spot for throw . This sounds like what you’re trying to achieve .

Thanks Boaz!

Sorry, got it about a week ago, but been too busy to mention it. This stuff works a lot better than the things I’ve tried before. I like the way the film helps smooth out the hot spots for my close task and walking around EDC light.

I tried the dot in the center, but my experience was that there was still a lot of light coming from the reflector so I still had a noticeable hot spot until I covered the whole lens. I’m sure that varies from light to light, but thanks for the suggestion and the film.

Mahalo!

Hmmm… Mine still hasn’t arrived yet… ??

WOW !!!

I am not subscribed to this or any thread but make a conscious effort to check this thread pretty often . This has happened before and I’m starting think in some cases it’s other family members opening mail and not realizing what DC-fix looks like . It can look like there is nothing in the envelope at all . Recently I have started writing DC-fix on the back of the sheets just to avoid this issue. But I think in the future I’ll add some odd shaped samples of other diffuser material i have over here and wrap it all up in a letter thanking people and explaining what it is for the moms / wives who like opening mail and tossing stuff out . I could write “important flashlight material enclosed ”……but in some homes that might be reason for a divorce .
private message me StevenS with your address again so i can double check it ….and I’ll send you some more DC-FIX.

This is great stuff, saved one expensive light for me and made a couple others really nice for task lighting. I’d like to try it on a few more but i seemed to have misplaced my envelope. I wonder if at some point i thought it was empty and through it out. I may need to buy more. It’s great to see it’s still available.

It’s alright. I’ll wait some more… :+1:

What kind of lights have you been using d-c-fix on? I read it cannot withstand high temperatures.

Here’s Olight R50 Pro near a wooden surface on turbo for under 1 minute.

Look at the lens in that photo. It isn’t very hot. Only the “wooden surface” that the light is shining on is getting so hot. In fact, I’m almost certain that most of the heat showing in the lens area, is actually being read from the reflector behind the lens, and not the lens itself. I know the DC-fix will absorb more light (and heat) than a clear lens, but I think the DC-fix will be okay for at least that light. :wink:

I already re- sent it . I wanted to make sure there weren’t any problems. You said in your PM that the delay might be in your mailing system …. But I didn’t want you to have to wait any longer than you already had .

Let me know when you get it / or don’t get it …thanks again
