My Sunwayman T40CS XM-L U2 arrived and it no longer has the nice dark brown/grey finish, which I had seen in some earlier T6 models. My unit is a very dark grey/black finish, which is equally good. After opening the box, I immediately placed it in line next to all my other single XM-L throwers and noticed that it is a little shorter in length. I particularly like this, as smaller lights that pack a punch impress me.
The manufacturer's specs are a little higher than the original T6 version and I am happy to say that the additional Lumen output and Lux is a welcome addition.
High 845 Lumens (2hrs) Medium 220Lumens (8hrs) Low 20Lumens (60hrs)
I concur with the excellent regulated runtime of 2 hours on high using 2 x AW 18650 3100mAh cells and I would expect my Redilast and Eagletac 18650 3100mAh cells to have a similar performance. It is nice to see that the manufacturer's specs are accurate.
Although many may have seen images of this light, it is quite different from owning one, as I do not believe that the photos do it justice. I feel that words alone cannot fully convey the quality of this light and the hard anodizing is outstanding. I am an advocate of flat stainless steel bezel rings and this does not disappoint. The styling around the head is a nice disguise for good heat dissipation, as this light is driven harder than all of my other 2 x 18650 single XM-L throwers, yet it manages to sustain a longer runtime while still maintaining onto excellent regulation. This is quite an achievement for a production light. I have only ever been able to replicate this type of performance while making a new copper heat sink.
I really like the beam profile of my unit, as it does not have the rings, which are present in my Crelant 7G5 V2 and other T40CS T6 units. I am also incredibly pleased with the tint. I would consider the colour temperature of 6500k to be a brilliant cool white. Mine is a rather impressive 55,200 Lux and although this is not my best thrower in it's class (2x18650 single XM-L reflector thrower) the difference is not significant. To put things into perspective, if I could keep only one light that used 2 x 18650 XM-L thrower, then it would be my newly acquired Sunwayman T40CS U2.
