Hi , thank you for answering even if partially . So generally the external part of the light is pretty durable other than lens ?

I have two D4s, a D1, and a D1S. My friend also has a D4.

I do not abuse them but I’ve been very happy with all of them. I use the D4s most, and have had a few drops onto hard surfaces without any failures. Just some scratches and scrapes.

The anodizing wears quite easily on my smooth black D4, but this is just cosmetic. It has a few bare spots from rubbing against my jeans while clipped to my pocket.

A broken lens is simple to replace by unscrewing the front bezel. If you break the glass lens, perhaps you could replace it with a more durable polycarbonate lens.

Im not looking to torture test them . for me if it can survive accidental drops on the ground and concrete and puddles of water is plenty good . where do i get the replacement lens from if say i broke it(i hope not)

Since you’re located in Singapore, you will probably purchase the light from the manufacturer at Intl-Outdoor.

Ask Hank (the owner) if you could also order one or two spare lenses when you purchase the light.

For reference, the D4 lens measures 25.5mm diameter and 1.5mm thick.

I work in construction and I use a BLF A6, which has been subjected to drips and knocks. Cheap, rugged and simple.

Not that the d4 couldn’t also do this. It’s a very good light, it’s just more extreme in a way that you probably don’t need for work

If the quality is the same as the BLF A6 then im getting one asap . lol . i know the max lumens output for the emisar is overkill for anything practical but its still nice to have that super bright burst coming from such a small light.

It’s way longer, I wonder why ? I mean, 18650 and 26650 are the same length…
I hope that it has a thick shelf under the MCPCB !

Other than better heat dissipation, can we expect the same output and emitters from the D4S as we are seeing with the original D4?

Assuming that it is indeed a quad with Ledil Angie-S optic, the light is at least longer because the optic is longer than the Carclo 10622 (well, just by 3mm actually), the output should be about the same as the D4, but with a bit longer turbo-time, the throw should be considerably better: a narrower hotspot.

Well if the D4 is transposed to the D4S, then maybe Hank will turn the D4 into a Meteor M43 like light; basically four D4 lights into one M43 form factor with 4×4 emitters.

Oh wow, such hype! That’s another must purchase.

It looks so nice and fat too.

Maybe there will be a 26350 option too?

I also wonder if the extra length is for some of the jumbo-sized 26650 cells out there or maybe with a sleeve to accommodate a 21700. Looks cool anyway.

I expect the lanyard hole adds a few mm in length as well, glad to see that included!

Has anyone before in these 4700 posts actually checked this?

And where in the driver is this power (24W!) burnt off? Shocked (the light is fine after 10 seconds reverse battery contact).

That dark blue D4s looks awesome, but is that a new blue DRESS next to it as well? It looks shinier than the old Cyan color.

Good catch.

Comparing manufacturer predicted beam specs for XP-G emitters, since both manufacturers have that emitter modeled:

Carclo 10622: 4.3 Cd/lm
Ledil C12885: 8.0 Cd/lm

Aside from a different optic, I wonder if the additional height also fits in any changes to the driver.

Given more PCB area, it seems pretty reasonable that additional 7135’s could be added, although that doesn’t add height.

To be honest, I’m not thrilled with the optics choice.
Not that Angie is bad, quite the opposite, but siamese optics are a proven choice that enables higher throw in the given size.
Angie with a rotated-pad-pcb is going to deliver a largely artefact-free beam. But personally I’d rather take a large few minor artefacts for a more pointy beam.

Still hoping they will come out with an aluminum 18650 battery tube for the D4 with knurling.

I hate smooth tubes and the Titanium version is too heavy for my pocket.
