Review with X-ray image: Emisar D1S

on x-ray the tail cap is not fully screwed down and the springs are very much compressed
are protected cells too long?

The tailcap was only unscrewed as the light was locked out, and forgot to screw it back for the x-ray image.
The maximum cell length permitted is 67mm which realistically means that only unprotected cells are allowed in this light.
The springs are very compressed even with 65.2mm batteries such as the GA (in the image).
I could fit a button top added VTC6 at 66.5mm.

I too would like to see discreet mode levels so that runtime is known.

Is not mode options one of the programmable features? It is on the D1, have tried it myself and like the ramp better.

As far as I’m aware there are no discreet modes on any Emisar lights unless you re-flash.

Oops, didn’t see this review until you shared the link elsewhere. How did you get the x-ray image?

Some of the things on your “didn’t like” list are already fixed in newer firmware, but I don’t know if/when Hank will use it. Perhaps it’ll happen eventually (particularly if I finally update its thermal code again).

Thanks stephen for another fine review. Do you have any way to measure the drain on the battery when switched off?
Edit. It appears the deals off.

Thanks for the update. I used a medical x-ray unit (I have to sometimes test, so might as well have a flashlight in the beam).

I don’t unfortunately. I always mechanically lock out my lights anyway.
Which deals off?

Another photo taken last night. f/5, 3secs, ISO800. Cameo appearances from 2xConvoy S2+ and Thorfire TK15S.

Love that X-Ray image! Shows the correlation between all the parts, even the junction of threads, really cool seeing that without having to be a cut-away.

Nice work!

thanks for this different review.

Do you plan to make beamshots? What’s 130kcd worth in feet?

The link in the OP doesn’t show the light.

Great review… +1 for the xray image, those are awesome.

Standby drain should be lower than the cell’s self-discharge rate. I measure 21 uA on mine, or about 16 years of standby time per charge.

After I’ve reflashed with different code and fuses, I measure 0.31 uA, or about 1100 years of standby time per charge.

I generally use mechanical lockout on the stock firmware because I don’t like clicking six times and then waiting for two slow flashes… but after reflashing I use soft lockout instead (4 clicks and a single fast blink).

I have a nearby open space with 220m clearance. Unfortunately the my last two attempts of using that space were thwarted for various reasons (flood and people rugby training in the pitch black). So hopefully sometime soon I’ll have a longer distance shot. Given that my L6 has a useable beam (as in being able to discern objects) for around 200m, I would expect the beam to be useable for over 250m.

Thanks TK.

That depends on how much light you want on the target, I like about 1 lux on my target to be able to actually see it, so about 350 yards or 1050 feet. Real world experience seems to bear that out for me.

I really hope that Hank adopts your new firmware! That’s one of the things that’s keeping me from getting an Emisar now, but sooner or later I’m bound to cave in.

(I know I could reflash, but I’d prefer not to until I’ve practiced a bit on other lights.)

I got my D1s today , I really like the new grippy finish.

That’s because you have to login to M4DM4X to get the product page.

Thanks stephen. The dumb mooses reputation is intact. :stuck_out_tongue:
