Had a chance to try it yet?
Cabfrank,you’re welcome ….
Yes i still have plenty left.
Lets just say …they had to shut down one production line to run some more …
Everyone knows what I’m getting them for Christmas … because I wrapped presents with it .
Ok, so no one here that has purchased has felt like posting about their impressions on DC Fix?
I like mine the best on the optic in my DQG Tiny III 18650….
I haven’t actually used any of mine yet….
Mine just arrived. I have a couple of headlights that I think are too spotty, and I’m going to try it on one of them, if I can cut it correctly.
Thanks,
Jim
It has not been mentioned in this thread yet , but this film will also even out the tint shift , or 'Cree rainbow' effect .
Ok, I tried this with one of my headlights. It’s a 3xAA Rayovac that I like using for close working. It has a TIR lens, but it’s got a really/ugly-shaped beam and very bright/distinct hotspot.
My wife cut a piece of the DC-fix to fit over the TIR, and I just peeled the backing off and stuck it on the front of the TIR.
The beam is much “nicer” (no more ugly shape and weird artifacts), and the hotspot doesn’t seem as intense as before. I still can’t use it on high mode for really close up work, but the medium is very useable now.
Hi Boaz,
Many Thanks once again for “Bulk Buying” this for us.
Been wanting to try some of this for ages!
I ran a quick test with a Lucky Sun P26650 I had modded (warmer tint LED on Noctigon, and 105C driver), and diffusion-filmed as I wanted a more “spill” beam, and used some generic privacy film for house windows, purchased off eBay.
Readings off light meter at 1 meter using old film were:
Low 03 Medium 09 High 24, and This Film:
Low 05 Medium 15 High 43,
so (if my math is right) +67% for Low and Medium, with High +75%
Good result and still has slight “hotspot” definition with great “Spill” too. I’m Very Happy with the results.
S-L 
Thanks for the info splott. 75% better than your old generic film is impressive …This just reaffirms Selfbuilts numbers .
i did some quick seat of the pants tests on two BLF A6’s
- Stock light at 36” inches off the floor the edge of the spill hits the floor at about 4 and a half feet
-With DC-fix
it hits the floor at 6 inches
increases the flood so wide i’m always blown away .
perfect for headlamps .
I use diffuser film on lights in place of lanterns or a traffic wand diffusers because they cause way too much glare .
diffuser film is much easier on the eyes .
I’ve tried DCFix Sand on 2 lights; 502b and X6, both for mountain biking.
Without DCFix, they were not ideal for MTB as hotspot too intense with no spill. With
DCFix, both were perfectly smooth and floody beam, tried both on handlebar
as well as helmet. Thanks Boaz.
Unfortunately, I haven’t had time to try it yet. I think it will be great for an older light I use on my bike, when I get a chance to play.
I do not remember who called this stuff “Mag-fix” for being able to de ring stock maglite beams, but they were absolutely correct… My Mini Mag beam looks awesome and as soon as I find my 2D, I will hit it up too….
Nitecore HC50, BLF A6, Convoy S2 XP-L red, thanks Boaz.
I used the DC-FIX on three lights
- my “working” aka less then perfect (reflector dull) P36 a it is a definite plus!, but I am in no rush to use it on my shelf queen versions. High power lights are nice when you can see that they have punch.
- on a project s7 triple nichia 219C 5k, used it on the medium flood TIR and compared it against the full flood TIR version (more below).
- on a solarforce 3.04 amp 3C XML2 emitter, for me makes the light much more friendly and usable.
Something I noticed is that it really will not make a thrower, a flooder. But it does seem to blend (a lot) and broaden (a little) the hotspot out nicely with any light. Again it does not turn a thrower into a mule.
As far as #2 the (before) medium flood is/was brighter then the full flood (which takes a lot more juice, but for me the full flood is a nicer profile if you have the power).
(after) the full flood is now brighter then medium flood with DC-FIX. the medium flood is now more like the full (but still not as even as the full flood) but at the cost of not being as bright and focused as before (makes sense if you think about it). 
So in total I like using DC-FIX but it is not for every light. But for lights with “issues” it is a great way to make them more friendly and usable.
I think it should be a given for headlamps with enough umph.
As far as application I did not follow the instructions I just popped out the lens to be covered, cut a square large enough to cover the lens. cleaned the lens and pealed and stuck the DC-FIX on to the lens, then I just used scissors to trim off the excess DC-FIX, no sweat easy peasy.
Dang - no time yet to try it, but from all the posts on applying it, totally confirms Boaz's enthusiasm for it 
. Got a few lights that could use some TLC fix'n, so hope to give it a go in the next few days.
Coming from film without adhesive this seems harder to put on and defiantly harder to get off . OTOH it stays and isn’t going anywhere either …To remove it i use a hair dryer to soften it up and it peels off easily ,
to apply after peeling back the paper i install it like you’d do automotive privacy film …wet … so it can be moved around a little then I work out any water under the film .
If you can unscrew a bezel and pop out the glass than obviously it’s a much easier way to go by just sticking it on and trimming the edges .
I keep looking at a couple other kinds diffuser film as well but can’t find a good source yet .
Thanks for the hair dryer tip. I does come off easier with heat…
I am seriously looking around to find where else I can use this stuff… Try some on your remote for your TV… 8) Works for me…
I like this stuff! I tried it on a Nitecore MH20. It smoothed out the beam, made it more floody with less of a hot spot. Don’t get me wrong, there is still more light in the center, but it is not as hot. Ditto on a stock S2. I find that for a GP (general purpose) light I find the hot centers distracting. And I tried a piece on an old Maglite 3D. Nicer but it still is just a weak light, just a smoother, no rings, weak light. Back to experimenting… maybe a second layer to see what happens….
DC Fix won’t make your Mag brighter, but a XHP-50 might!
Yes !!!
I still have more DC-FIX available ...
In the age old tradition of BLF ... I bought a bunch .
Glad you guys are enjoying it . I'm thinking of starting a new affiliate shill program where anyone who sells 50 sheets gets one eighth of one eighth of an inch ..So get in on the ground floor here ..If you can get 5 associate shillers under you you will receive 1/16th of a sixteenth of an inch of anything they sell ..* Some restrictions may apply ......do not use if taking any other medications ask your doctor before using .If you have any rashes itching ,burning or headaches please stop using at once and call a licensed family therapist to have your head examined .objects in the mirror appear larger than they really are .Please remain seated until the captain has turned off the no smoking lights and thank you for flying Dc fixed wing airlines .....We will now return you to your normally scheduled program . This is truly an opportunity of a lifetime .
