DC-Fix Diffusion Film Sale

I am going to try it, worse come to worse, there are two sides to the lens that I can DC-Fix… Lol

Agreed, thanks Boaz!!

PM’ing you - would like 4 sheets (or whatever they are)…

Boaz:

Received mine in the mail today. Thanks!

Now, which flashlights should I try first? :nerd_face:

Got mine in, thanks! I am impressed, most of the accessories like this seem overhyped, but the DC Fix works very well. I think I will be using this on more than I thought, including o e of my BLF A6’s!

How do you ‘stick’ it up on the lenses? Thanks

Remove lens from light . Clean it with alcohol . Cut a piece of film slightly larger than the lens . Peel backing off film and apply it to the lens , making sure to get all of the bubbles out . Use a razor blade to trim the film by cutting flush against the edge of the lens at a 45 degree angle .

I usually put the lens back in with the film on the inside . This allows the bezel O-ring to seal properly .

Any questions ?

I’ve got a kinda throwy headlamp currently XM-L T6 that I want to put a 365nm UV emitter into but would like the beam to be more floody… has anyone tried using this film on UV lights before?

Could not be more well explained than this. Perfect and thanks _

Nice Jack !…

Thats the proper way to do it . I usually just take out my socket set ,find one that fits inside the bezel and use it to trace a circle , Carefully cut it out and stick it on the outside of the lens .You want to do a pretty good job so you don’t have any light leaking around the diffuser .

I now have this on my BLF A6, the one I have an XPL HI swapped in place of the stock emitter. The previous hotspot is now well blended into the edges of the beam. It really does give a good smoothing to the beam profile.

Wait a minute…

You swapped out the stock emitter for a XPL HI (tighter spot, more throw) and then negated your efforts by affixing DC Fix to the lens? (obfuscated spot, more flood)

Tell me how that makes sense, please. I don’t understand.

Any info how much heat can this thing take? I would like cover some spotlights around the house running from mains voltage. It’s probably not designed for that kind of abuse.

From the website:

Edit: Oh yeah, this too.

It is a V3 2D XPL HI. Better tint than the blueberry infused stock 1A for starters. The “increased throw” is just a bit tighter hotspot, it still has that now, but the edges blur into the spill. It does cut the throw some, but still better than stock….

Not to mess with you, but all this is for experimentation anyway, sorry to leave you scratching your head at my follies.

I am contemplating a hole in the center of the DC Fix to see what that would look like…

I’d be curious about the results.

My guess is that the edge of the hole would be an “artifact magnet”, creating a highly visible point of discontinuity in the beam profile.

I will have to look for one of those hobby stamps or cutters that cuts about 1/2” circle with jagged edges. I think that it will be hard enough to line up on center, but a jagged edge should minimize this somewhat…

I will post pics if I do this, but I do not know if I will have time.

In a reflector light, the hotspot comes from around the edges and the spill from the center area. You would be adding a little spill, possibly, and a few new artifacts to the otherwise smooth beam profile, and not much else. If you really want to play experiment, instead of having a hole in the center of the DC Fix, you could add another color to the center to replace the rainbow effect that Cree forgot to install into the XPL’s. :stuck_out_tongue:

Anyway… So, are you saying that the difference of a tighter hotspot that you got from changing to the XPL HI is bigger (stronger effect) than the difference in the other direction that you got from putting DC Fix on the lens? I’ve never used DC Fix, so I’m trying to learn about it.

Yes, I switched the DC Fix lens to my Eagle Eye A6 with a Nichia 219C and the flood is more than with the XPL HI on the BLF A6. I like the profile of the EE A6 with the DC Fix more, it is not as bright as the BLF A6 and makes a great flood as well as a more neutral tint.

Like I said, the XPL HI with the DC Fix was good, and still throws about like a regular XPL, with a brighter middle and less defined (but still brighter) hotspot. So the DC Fix is not a total wash for throwers either. I may order an extra C8 lens to experiment with…

I really like the DC Fix on the optic of my DQG Tiny III 18650, now it is a flood…

Got mine, thank you Jeff!
