I finally have both the DC1 and the DC2 in titanium, both purchased on CPF ! I am now running H17F or the Lucidrv2 driver in both with N219c triples. They are both the same brightness on direct drive, but, the DC2 seems to have a little more throw, maybe, TBC. Of Course, the biggest advantage of the DC2 is how much it can take on full blast. Bigger Copper Pill, better heat dissipation, bigger battery. When I go to the car show at night, I prefer the DC2. I can use the light on many engines on full blast and easily manage the heat and battery. There is no loss of brightness the whole night. On my daily carry, I use the DC1, where I rarely use direct drive. Direct drive is too bright for indoors or in the car, so, I tend to only use it outside when there is zero light, and this is rare where I live. The DC1 on 25% or 33% is plenty bright for almost all jobs, so, with a 1100 mah battery, you get quite a run time on the DC1 with those brightness levels. All that being said, the DC2 is very impressive and quite a unique Triple with a great copper pill. Enjoy the Pics below !!
Edit: BTW, the best setting I found on the H17F with the DC2 is: short Cycle Memory, steps - 17, 20, 22, double tap 24, 2, then 2 more low modes. Something like that.... So, this way, it always defaults to 17 for daytime, and you are always between 17 and 22, then 24 when you double tap. At night, you cycle through the modes to get your low mode set when you need night vision. It actually works great for me, and I only have to go through the 3 low modes when I need night vision.
