Tell me please . Someone has done inserts (film or …) to scatter the beam(increase the beamwidth ) ?

Yes, some use a film called DC Fix in what is called a “Sandstone” pattern to act as a diffuser and make a floody output.
Some have used a clear spray paint with a light application on the reflector to create an orange peel effect, also for a more floody light. Still other’s have acid etched or sand blasted the lens… there are multiple ways to create the dispersion of light, virtually all cost a percentage of output and some are “safer” than others. (ie: a film can be melted or caught on fire in an extreme output scenario)
What’s the benefit of buying a very throwy light just to diffuse it and make it floodier? Do you need the extra mass for heat sinking? Otherwise it just seems like the worst of both worlds.
I suppose I could understand a D1 with an OP reflector, but the D1S is chunky and very purpose built.
Most people are making temporary diffusing lenses for throwy lights just to make then for floody for inside purposes.
And you can ask for a photo or a reference to the goods? Well when it’s safe
I want to make the beam a little bit wider. Get a combination of long-range and scattered rays
The reflector allows light directly from the emitter out the middle of the lens, this goes on to become the spill. From around the edges of the lens comes the collimated light of the reflector which is seen in the hot spot. Perhaps you could affix a disc of DC Fix in the center of the lens, diffusing the spill to a broader pattern while not affecting throw from the hot spot.
You can experiment with coins or tape covering the center of the lens to see just how much center coverage would affect the beam profile in a way you find desireable.
Seems strange to block the middle, but you may be surprised how little around the edge creates the throwy hot spot, play with it and see…
No need to yell at me.
I thought yelling was all caps?
You got me wrong. This is the wrong translator
When did I scream at you?
Because the Butler Creek Blizzard scope cover gives you the BEST of BOTH worlds. It adds very little girth to the D1 and weighs hardly anything. With the lens closed, you have a very nice area light. With the flick of a thumb you still have the thrower the D1 was designed for.
Boaz here sells the good diffusing film for cheap. Just cut out a circle of the film, (I used a U.S. quarter as a pattern), stick it to the inside of the flip off lens and you’re in business. Simple and fairly inexpensive and I love the setup.
Thanks for the recommendation. Can I give an address or a link to which I can contact him?
Hi valera,
Go to the Budget Flashlights Buy/Sell category and then to the Want To Sell sub forum. Boaz’ diffusion film sale is near the bottom of the first page.
Get his regular stick on diffusion film. It goes on easily and is removed easily in case you need to reposition.
Thanks for the answer. This is here DC-Fix Diffusion Film Sale
Where can I see the photo, to understand how to do it?
P.S “Because the Butler Creek Blizzard scope cover gives you the BEST of BOTH worlds. It adds very little girth to the D1 and weighs hardly anything….“
What are the options for attaching the film to the flashlight Emisar D1?
See here, posts #200, #201, and #203. DC-Fix Diffusion Film Sale - #200 by Terry_Oregon
DC-Fix is a 1 side sticker. First, you measure and cut the diameter you want (according to the lens) and then you take the transparent sticker (DC-Fix) out of the “paper sheet” that protects it! And then you glue it above your lens!
EDIT: And post #209
In many cases, it works well to cut the DC-Fix slightly larger than the lens, remove its backing layer, put it on the lens, then use a knife against the glass to cut around the edges. This gives a perfect fit, assuming you want to cover the entire lens and don’t plan to remove it.
You can reduce the temperature of heating the “head” of the flashlight when working at a maximum. Are all the flashlights Emissary D1 very warm?
Probably a bit late, but you can set the temperature limit to a lower value so the light will reduce output earlier. Or you go on turbo mode and ramp down just a bit. The lumen output won’t be reduced much, but the current draw will drop a lot.
Emisar D1 actually have a reasonable heat generation, so there’s not really much to worry about. The D4 is a different story.
Has anyone tested Nitecore 34mm filters with D1 by any chance? I do want to get white/diffusing one, I’m just worried that head might not get deep enough to fit well.
I think this diffuser is roughly 2cm deep. Could anyone tell me how deep D1 bezel is?
