I've just noticed these backlit switches, and would have loved to have this on my recently ordered Al version, rather than the front color LEDs.

This is apparently only available for the Cu and Ti versions, correct?

Weight of the full copper version? It would be helpful to have that listed on the product pages for the Ti/Cu/CuZn lights as well.
...and for the Al as well.

Weight (unlike size) is missing on all Emisar lights description pages, whereas it is mentioned for Noctigon lights.

Backlight switches are not available for the basic aluminum D4V2, only for D4V2 Brass, D4V2 Cu, and D4V2 Ti.

Thanks lightdecay for your quick answer.

I wish they were, as an option which I would be happy to pay for. I didn't choose Al for its lower price, but for being more lightweight than the other versions.

I always thought this myself. I would never choose any of those materials over aluminum due to weight, but I would gladly pay more for the lighted switch option also.

I’d say if price is not a “concern”, the cu+ti weight must be close to the AL.. maybe? Albeit a different balance of weight, titanium is a decent degree lighter then AL, I believe. I’m sure someone who have both can verify this for us?

Ti is 2/3 more dense than Al.

I emailed Hank and asked if a backlit switch would be an option on the standard D4V2 and his reply was that there were no plans to do it. That was a few months ago though. I’m holding out and not ordering anything else, because every time that I do the upgrades are always out minutes after I get my shipping notice.

I don’t have any plans to order another D4v2.

… but if they add the backlit switch to the aluminum version I would.

I’m about to the point where I’m going to order every light Hank sells with every emitter he has. I love my D4V2 and my 2000k KR4. I should do the math on that Smile

Hank told me lighted switch on aluminum was a no go when I asked him last week. Really wish he would do it. Didn’t stop me from ordering another D4v2 with my K1 though…

Not positive on that.

I don’t have a full-copper D4V2, but I do have full-copper for a number of other lights.

Copper conducts heat so well the body tube of the light where your hand sits can get burning hot far faster than an aluminum tube.

The result is the electronics might be protected… but you may need gloves (or an oven mitt) to actually hold the light.

I noticed my fw3 copper got hot very quickly. My brass d4v2 does too, but with different emitters in my 3 lights of comparison it’s difficult to tell why or how much faster.

Ya my KR4 gets pretty hot cause I use it as my desk light. I try to keep the brightness at a level that is sufficient but doesn’t make the light get warm. Sometimes I neglect to do that and it gets hot. Not sure if that affects the life of the light but if so it just gives me a good excuse to buy another (:

I’d love a D4SV2 in 2000K.

I would love green anodization and clear anodization options for Emisar D4V2.

Someone on Reddit modded a D4V2 and silver color looks great. It would look even better with an optional backlit switch. Cool

Hank might not even be aware that you posted an image, because when you include an image in your post, and the website is not accessible, a browser might not give any indication that your post contained an image.

I’m really excited to see what happens with the d4sV2.. Will Hank rerelease all the colors again? Will he redesign it into a V3? Will it become discontinued to make way for a similar but upgraded version of itself? Will any of these three options I mentioned be available in cu..?

These are things that keep me up at night..

Put down the flash light and slowly back away. Unscrew one tail cap per night 1/4 turn and ween yourself off. We will get you through this.

These two beauties arrived yesterday (after only a few days of shipping)...

Please excuse the miserable image quality - I took some snapshots with my crappy smartphone camera.

Noctigon KR4 using 4x SST20-DR 660nm underneath a clear Carclo 10622 optic. At my request Hank installed a 7.5A constant current driver (default is 5A if I recall correctly). I was really impressed, even shocked a bit how bright this beast gets on turbo. Somehow, being blinded by deep red light felt totally different to my eyes than when using white light against a white wall. Anyway, 10 seconds later the head's temperature has climbed significantly, so I will use turbo wisely and for short bursts only. Maybe it's not a bad idea to manually set an ultralow threshold in Andúril's thermal config...just to be safe in case. Big Smile

 

Noctigon KR4 using 4x E21A 2.000K underneath a frosted Carclo 10623 optic and the 5A constant current driver. The light beam is real eye candy, actually representing the quintessence of candle light. The first thing I thought of was testing the candle mode in Andúril - amazing is the right word to say. In comparison to the SST20-DR version this KR4 took an eternity to heat up that much. Maybe I should tweak thermal config a bit to see what presets work best. I removed the clips on both lights and feel very happy with the alternative lanyard rings Hank supplies with these lights. The matte black anodizing is just perfect, same as the overall quality of both lights.

 

Hats off to Hank and ToyKeeper for bringing us more and more seductive flashlights. Smile

I highly recommend the 10622 clear optic for E21A 2000K and E21A 2200K. Throw is a lot better, and tint shift is a non-issue.

I did not try it with E21A 2700K yet. E21A 3500K does have noticeable tint shift with 10622 clear optic.

I’ve got a brass E21A 2200k and I can’t get the frosted optic out. Every other D4V2 is easy with a piece of tape but I can’t get this one out…

I had to use 3M tape. I pressed it on the optic for 20-30 seconds and then pulled up and the optic popped right out. Pull up on both sides of the tape so the force goes straight up. I think the thermal grease acted like glue on the optic legs.
