TK's Emisar D4V2 review

thefreeman:

Hello,

Does anybody know the dimensions of the driver cavity ? (Diameter and height clearance for components)

Answering myself :

driver Ø = 22.0mm
driver cavity Ø = 22.3mm
components cavity Ø = 19.5mm
components cavity height = 2.7mm

I got one in cyan, it looks very nice, this is my first D4v2, the tint is not very good though (SST-20 4000K):

Lvl1 duv 0.0047
Lvl3 duv 0.0049
Lvl7@30s duv 0.0044
(I didn’t test turbo)

They’re probably not using FA3 bins anymore.

Why was the short tube made so you can’t use the lanyard ring?

Nvmd….wrong thread!!!

I relay enjoyed using this light, but now for some unknown reason the switch has stopped responding reliably, sometimes it works and the light functions, but most of the time no response, checked it, made sure it wasn’t in muggle mode, re set it but still, click click nothing - most of the time

Well was fun while it lasted, what was an intermittent issue is now permanent - the button is completely dead and non responsive

My KR4/KR1 tubes work with the lanyard ring, so I think it was fixed at some point.

Emailed Intl- outdoors and had a reply offering to sell a replacement switch as its out of warranty - however the bezel is on tight and wont be easy to remove without causing damage

You’ll probably need a new switch boot, too.

You need to get the retainer ring out, then grab the cables with some fine tweezers and resolder the button PCB. Obvioulsy you need a new switch boot, too.

I have one of those gold D4V2.

You’re in luck: you got the flush retaining ring so the light should be repairable. The flush retaining ring is removable. Unlike the raised retaining ring which I found impossible to budge.

Get a small Victorinox mini pocket knife, open the nail file.
The tip of the file should be a flat screwdriver with rounded edges.
Coming in from the side, insert it under the retaining ring just above where the rubber switchboot sat. Once it is wedged in, use it as a lever to lift up the retaining ring. The retaining ring is press-fit and should lever right up.

Next step is to desolder all the wires to the aux board and the star. Only attempt this if you have soldering skills and a fine tip for your soldering iron available. The wires to the aux LEDs are tiny. Before desoldering, take a picture so you can make sure to get every wire back to the right bondpad when reassembling.

After desoldering, remove the aux board and the star. Then insert a toothpick or other tool into the wire whole and push the driver out of the head. Once it is partially out you should be able to access to tiny wires which go to contacts on the underside of the red switch. Assuming those bondpads didn’t rip off the switch, soldering the switch wires back on. Reverse the process to reassemble.

Notes:

Since the rubber switch boot is destroyed you will need to obtain or make a replacement.
Also, if the switch retaining ring eroded the head coming out, you might find it may not stay in place. If you experience this try adding some super-glue gel between the retaining ring and head.
Due to the numerous small wires involved I wouldn’t recommend attempting this repair unless you’re an experienced modder. If not, you might want to contact Emisar about having them repair it.
It can be difficult threading the 4 aux board wires plus the 2 LED wires through the hole in the head and the star. If you have difficulty, solder some long narrow gauge guide wires onto the ends of the wires and then pull the guide wires through. Then desolder the guide wires.

Check out this very interesting mod where you can keep the auxiliary lights on by using the reflashing kit. Posted on Re-edit:

I have had 4 Emisar / Noctigon torches stolen from me.... wish they would start putting serial numbers or BLE locating functionality inside. I am sure of where 2 went but have no way to prove. These cost a good bit of money and anything would help....

I had the same thing happen to my D4V2 Ti and I emailed Hank... He sent me a brand new head to screw onto the battery tube, good customer service. Might be a bit of a wait, emailing in different time zones... shipping... but they corrected the issue.

Try taking the magnet (if any) out of the tailcap and put a BLE beacon inside.

How have you had so many stolen? Do you leave them lying around or something?

how do i know what driver mine has/?its red on one side and white on the other

For anyone wondering, I inquired about clear lenses, and was told they will be available next week.

OMG this is the manker switch design that I HATE!

Is anyone else having problems programming their light they bought recently?

I could not get into the floor/ceiling menu when I first got it, and decided to just leave it as is. I tried again yesterday after practicing on my MF01S with no luck. The MF01S works great, but 4 clicks on the D4 results in locking the light (from on or off). This morning I did a factory reset and now I can’t even change the aux leds. I would post the firmware version, but don’t know how to do that.
