Just arrived. No charged cells around as the 6 new ones are in the balance charger and probably won't be ready till morning - it's 9pm here. Hence no numbers yet, just some quick pictures. There will be a review in due course. It seems nicely made, but the pics can speak for themselves.
Nice satin finish that seems very even. Since I received it 4 hours ago, I've no idea of durability.
DX says that it is a 4.2V maximum light. The body says otherwise. Till someone finds out the hard way, it is a 4.2V light as far as I am concerned. That said, tail current with an 18650 of unknown quality and charge state gave only 1.9A at the tailcap so it might be 8.4V capable - or might not.
Size comparison with some other single 18650 lights. Piritlight SG-L8, RQ thrower, butchered Uniquefire HS-802, Eastward, Solarforce L2i. As throwy 18650 lights go it is reasonably small.
The business end. Nicely centred LED which is an XM-L
Body tube. Nice clean threads that have ben lubed.
The tailcap end of the tube - a nice large contact area.
The inner side of the switch and the other end of it. It does tailstand but not as well as some.
Back of the head.

EastwardYJ J06, Solarforce L2i with Solarforce low-voltage single-mode R2 dropin, RQ thrower. The RQ is on high and the EastwardYJ on low. The L2i is in its only mode. The hotspot in the RQ beam seems very much larger in this picture than it is to my eye - no camera sensor has remotely close to the dynamic range of a human eyeball.
