[Unboxing] XTAR D06 1600

Received from XTAR their new D06 1600 model featuring the latest CREE XHP-35 HI D4 LED. A dive light. But since I do not dive, this is a quick unboxing review of the D06 1600. It comes in a very compact box...


and I was surprise that they stuffed a charger and a battery inside too...


2 spare O-rings, a typical diving wrist lanyard, XTAR Ant MC-1 charger with USB cable, a 3500mAh XTAR branded 18650, a spare switch knob with magnet and XTAR D06 1600. I'm not too sure about the inclusion of both the charger and the battery, I believe that will depends on the reseller whether they are selling you a complete kit or just the light itself so if you are interested in acquiring this light, do ask your reseller.


The CREE XHP-35 HI D4 LED


A pretty deep reflector... yup, this light can throw the beam quite far...


this light's magnetic slide switch is the smoothest I've ever handle, just slide the switch all the way up to get the maximum brightness, D06 will ramp the brightness up or down depending on which way you slide the switch. One small complaint is it's not easy to get the lowest mode possible.

the different parts of the D06 1600, note that as dive light, it tries to double o-ring every connection


I'm not a fan of this spring, it easily fall off, so my advise is if you are replacing the battery, don't loosen the tailcap, but loosen the thread between the head and body like the following picture...


the inner tube is Al, it connects the battery negative terminal from the spring through this inner tube bare aluminium part to the head.


in order to replace your sliding switch with the spare one, or if you like a black sliding switch, you'll first need to remove the o-ring that is blocking the slider switch stopper and then loosen the stopper by turning it clockwise (or counter-clockwise depending on the direction you're holding the light) to gain access to the sliding switch.


was having fun showing off this lightsaber...


A perfect companion to the flooder XTAR Walrus D08...


A quick runtime test on the highest brightness level... I get approximately 13 minutes on the brightest level... I don't know what is going on with the 1600 lumens claim, I've done some comparisons with ~5 other lights and consistently get only ~1,110 lumens from D06 1600 instead of the claimed 1600 lumens. But then, my usual disclaimer: I do not claim the above measured lumens as authoritative nor an indication of over/under-stating the number given by manufacturer. My numbers are calibrated against some known light output (e.g. Fenix, SureFire) so take it with a grain of salt and just as a relative reading.

What I like about the D06 1600:

  • respectable runtime
  • spring design at both ends means it supports button top and flat top batteries
  • good throw

What I do not like about the D06 1600:

The standby current drain. Using different battery set yields different standby current drain...

  • 1 x 18650 - 0.6mA
  • 2 x CR123A - 0.8mA
  • 2 x 18350 - 1.2mA
