Hello,
I am sorry for my late reply.
I was informed by our engineer that indeed, Titan is using a PWM driver.
Our emitter is a P7 C-Bin which, with our settings, produces a more white beam from the MS900 as it can be seen by the side by side comparisont and review made by Baker in MTBR:

The battery runtime has been extensively tested by us. I will also ask the reviewer to test it once more for everybody to be sure. He is anyway planning to completely dissolve the battery and test it. Safety comes first and we want to be sure that there won't be any problem with our battery and charger.
Regarding our driver I hope you understand that we do not want to disclose any more information at this time because of competition. We believe that we managed to draw a great amount of light from a single LED and we actually feel very proud of it. The current tests and the information provided can help any user to do an informed decision.
Anyway I am still in your disposal for any question and I am aware that I still need to answer the low mode runtime question. I will do this before the New Years
On Behalf of the Gemini Team,
