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)
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.
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 4x4 emitters.
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.
