D4 Titanium!!!

I have one on order as well, but it was a bit of an impulse buy: it looks good but I will not likely use it much: I even find the aluminium D4 too large and heavy for pant pocket use (my E2L shorty is about the biggest light I can bear for pocket carry), as a bike light it is too expensive and bling (I tend to forget it and leave it on the handle bar, the bike is parked on the street at night), and for camping I have a headlamp and more throwy flashlights.
I can imagine that it will live in my weekend bag, but I guess it will end up on a shelf, showing off its glorious self, next to many many other flashlights :person_facepalming:

been EDC’ing my titanium D4 with 18650 tube for the last couple weeks. My impressions:

  • The light looks absolutely gorgeous. I picked the right-most color (I think version F), with blue and gold anodizing. It looks great, but at the same time not too flashy.
  • It’s significantly heavier than the aluminum version, but not too heavy for me to comfortably EDC.
  • The “hand-feel” is much better than the aluminum version. The square-cut knurling on the battery tube is excellent, and titanium is naturally grippier than anodized aluminum.
  • Still looks good after 2 weeks banging against my keys. On very close inspection the copper looks slightly worn, but the anodized titanium still looks absolutely pristine.
  • Excellent output and tint. Substantially brighter than my other D4s, even the one that I put XPL HI in.
  • Head gets hot incredibly fast…. much faster than my alunimum D4 on the same cell. As expected this leads to very rapid rampdown. From off at room temperature on a full VTC5A, the light starts at probably 4500 lumens of beautiful 4000K 5D tint, but within 45 seconds has ramped down to a max of maybe 50 lumens. This rampdown is much more rapid and severe than on the aluminum D4s.
  • While the head gets hot, the titanium battery tube remains cool. Unlike with the aluminum version, the only comfortable way to hold this light on turbo is to move your hand completely off the copper head.
  • Once the head gets hot, it takes a lot longer to cool to a comfortable temperature than the aluminum versions. In this version the heat is emitted from the copper head. This means much smaller surface area to work with than the aluminum version. Also dark anodized aluminum radiates better than my still-shiny copper-head. Copper also stores more heat, so there is more heat to dump.

Overall, I really like the titanium version of this light, but the incredibly rapid rampdown is a major drawback. Something like the new Zebralight SC600 IV with XHP50.2 that can sustain 2000 lumens for something like 5 minutes is probably a lot more practical.

I decided to run 18350’s in mine because of the heat issue. That copper head really does retain the heat, which is nice when its cold out :slight_smile:

RMM (MtnElectronics) has the D4Ti in stock … placed an order yesterday and it has shipped today.

Ordered a D4Ti Gold/Purple (I’m having a Goldfinger moment, I apologize!) 219C with matching 18350 tube and an additional 10623 frosted optic to change out for a more diffusive beam.

My D4 Aluminum models (an XP-G2 2B and a 219C) are V1 firmware and I take pains to use them modestly ; Max is only for very short term use.

I don’t want heat to blister my fingers (or any other body part). It will be nice to have TK’s V2 firmware in the Ti model. I expect that I will need it and really appreciate the results for the finer thermal controls and other features which were added.

I use Samsung 30Q and Aspire 18350 cells with the two D4’s I have presently and will use the same cells with this Ti model.

Equipment for firmware refresh is a few bucks only, you could try to upgrade them :slight_smile:

I got my Emisar D4 ti in, and I love it.

Also because of the 5000K 90CRI 219C which is new to me and has a great neutral tint and works very well with the optic, the new board with rotated pads help a lot too.

The 18350 tube is not finished as well as the rest of the light, rough grey-ish instead of shiny silver, and also leaves a tiny gap when screwed in the head, but I can’t be bothered, I decided against shelf-queen, this light is going into the EDC rotation. :slight_smile:

Darn it. I held out as long as I could. Your post put me over. Purchased!

I’m sorry that I did that to you Gunga, but with a bit of luck you experience what happened to me: what I expected is exactly what I got, and still it took me by surprise how nice it is. :slight_smile:

Finally got it after 5 weeks! Geez, this thing is heavy! If I didn’t know any better I would have thought it was stainless steel or something.

Overall nice though. Just more of a tank than expected.

Not super practical but I like it. I wanted the ti for the bling, the body knurling, and the bare metal.

EMISAR D4Ti from $59.99

About matches my opinion. Gorgeous light. Durable. SUPER-heavy. If I have it in a pocket I really feel it bouncing against my thigh. Not comfortable at all due to the weight.

Too bad the threads aren’t compatible with the aluminum version. I’d have loved to use the titanium tube with an aluminum head for less weight.

Also, I wish they came out with an aluminum tube with the square body knurling. Having knurling on the body is great, but its only available on the titanium version.

Danm! I just got the raw, with NW - XP-L HI V2 3A, 5000K, and titanium 18350 tube for what the base model went for before ($80)
She surely can’t blame me…right?

She can’t blame you if she doesn’t find out. Not that I’d advocate lying about it. But really, there are so many things to worry about, $21 doesn’t really rate, does it?

actually I saw the sale on another thread and jumped on it. :money_mouth_face:

(fyi the 25% off applies to the accessories also)

Is this sale still going on?

Yes, sale is still on. I broke down and bought one :person_facepalming:

Ordered one from Hank on 5/16 and it arrived today. Fast!

Jake,

I just bought the natural titanium D4 with the accessory 18350 tube and nichia emitters. It was an impulse buy, and I’ve decided I wanted the XPL Hi emitters instead. So I’m re-ordering the light in that emitter configuration, and I will be selling this one at a discount as soon as I return home and take some pictures (I’m currently on travel). It has never been carried, never dropped, and probably has only about 10 or 20 minutes of total play time on it. I’m still on the first battery charge.

I don’t know whether the Ti version loses “a couple hundred lumens” over the standard version, but I can say that this thing seems to put out three or four times as much light as my Zebralight SC600, which was until now the brightest I owned. The hot spot intensity seems similar, but the D4 is more like a hot “zone”, much much larger.

This is also the most attractive and best-machined flashlight I have ever owned. It’s like a piece of jewelry. I know I’ll wind up carrying the D4 instead of my SC600, because it’s smaller yet more powerful, but probably not until I find a protective pouch to fit it.

best regards,

Martin

Nav, when I look closely at my light shining on an even surface, I think I can detect the first stepdown at about 15 seconds of operation. The change is small, though. I never tried for more stepdown because the head was as hot as I wanted it to get. I’m fine with that factory setting, as I doubt I’d ever run full power longer than 5 or 10 seconds anyway.

best regards,

Martin
