Just got one delivered from MT, thanks for the review 
That blue is a fun new color. Nice to see something out of the ordinary.
While I like the new color, the black switch bezel is something I REALLY like!
Wonder whether these are one-offs or future production colours.
Thank you freefly.
the green is much more dignified
the blue might be appropriate for baby boy announcement gifts
(better than cigars)
I have tested my D4 throw using a Efest 2600 imr cell which has the XPL-Hi V3 1A led option-
At 4.19 volts - 21kcd and 4150 lumens
At 3.94 volts –18kcd and 3500 lumens
For comparison i measure the zebralight sc600 mk11 peak values at 10kcd and 1070 lumens using the same gear.
My XP-L HI 1A with VTC5A in the cold UK out throws my Acebeam X80 and that has 27,480cd!!!
I don’t think that’s a black switch bezel. I think the switch retaining ring simply hadn’t been put in yet. That’s how the D4 looks with the ring removed.
One picture shows the blue model with a switch retaining ring, the other picture shows it without.
(… Too bad there wasn’t a pic of the D7…)
So we can expect pink?
The X80 has a beam pattern of about 1.1 cd / lm. It’s basically a “mule”. The D4 XP-L HI does about 4.7 cd / lm, which puts it at the floody end of general-purpose lights but still quite a bit more throwy than a mule.
In general, if a light has a low enough cd / lm value, it doesn’t really matter what its rated throw number says. The bright foreground area will make anything at a distance hard to see. The X80 is only for illuminating at a short distance, for pretty much the same reasons as a light bulb.
Similarly, if a light has a high enough cd / lm value, it doesn’t really matter how many lumens it makes. It won’t be useful for up-close tasks, for the same reasons as a laser. The light needs to be spread across a wide area for up-close work, instead of just a small point.
The X80 is effectively a portable 25,000 lumen light bulb. It’s not quite as floody as a traditional 360-degree bulb, but it’s very close to many 180-degree “downlights”.
Ah, so that’s where the last 4 Aspire cells went. 
I had the page open to order, but went to eat first and when I came back they were out of stock. Oops.
Just checked my new d1 with vtc6 at 4.19v and got 1600 lumens and 51kcd, with aspire 18350 it got 1480 lumens and 48 kcd . I checked tailcap amps and got 6.02 amps.
My first “big light” was a Thrunite Catapult V3 XML-T6. about 750 lumens and 40k lux. The nickname was throw king, haha! Oh, good ol’ days… 
I just checked my d4’s the 219c got 11kcd and the xpl hi 3a got 21 kcd
Nice to see some measurements of the D1 [51kcd yeha]- I ordered one myself in V3 1A a couple of days ago.
The D4 is so impressive, i had to to have this one along with a 18350 tube in green this time.
Yeah, I haven’t seen any pictures of the D7.
Isn’t he using a different TIR optic than the stock one?
But based on TK’s testing, it seems Vinh may be over estimating the throw?
As far as I know, he’s now using the stock optics.
Aspire seems to have them. I ordered 5 for $20 a few month ago - no extra shipping charge.
Nice packaging BTW, but no plastic case.
