Diffusers for D4S

Finding remarkably little information on compatibility for diffusers. I'm trying to acquire diffusers for my D4S and SP36.

I've found old threads mentioning the Convoy #36 diffuser being a great fit for the D4S. Unfortunately this diffuser doesn't seem to be available anymore.

Fenix AOD S, M, L series diffusers are readily available but there is very little info out there on compatibility with non-fenix lights. Sofirn is selling several diffusers but there is very little info on compatibility with other products.

Is there a list anywhere of compatible lights for these common diffusers?

The AOD-M fits best on a 40mm head, but can also fit on a 39mm head with a little modification

ToyKeeper’s review of the D4S indicates,
Measurements:
Diameter (bezel): 38.9 mm
Diameter (widest): 42.3 mm
Lens: 36.0 × 2.1 mm

What modification is required for the AOD-M to fit the 38.9 mm bezel, something easy?
Thank you.

The diffuser for MF01 Mini actually fits. I have both lights and the diffuser, it’s slightly smaller longer in so it stays on.

Diffuser

This is quite helpful. Thanks!

Cut off the bottom 1/4”–5/16” of the diffuser. Since the sides of the diffuser are slightly tapered, this will expose a smaller inside diameter. I haven’t actually tried it yet, but I plan to.

I checked today how this diffuser (for mt07/mf01 mini) works on D4S. It fits almost perfectly, but is loose. If you flip the flashlight it falls down. It works only if put on and stand vertically.

If you just put it on further in, so the narrower part is around the lens, it stays on even when moving around upside down. Trust me I’m using it.

And what do you think about it? OTR silicone diffuser (37.5mm).
In the picture it is showed on X5, whose head diameter is 40mm. The head of the D4S is 39mm.
This one should fit perfectly. I think I’ll order one.

I use the FireFlies E07 diffuser

Is the diffuser for E07? I didn’t know. Can you say where you bought it (link)? There is no optional diffuser on the FF page.

Just ordered this one. Thank you. But I could not locate the FF E07 diffuser. If anyone finds a link, please let us know.

Today I received an OTR diffuser. It fits perfectly.

That’s a nice fit. Apologies for not seeing your query earlier, I got it from Banggood.

My favourite diffuser, Naturehike S works great with D4S.
