Just to throw my 2 cents in, I have has the Titan Plus for months. It is my almost forgotten light only because it goes everywhere I go(outside the house), but I am often carrying a new EDC to try out. Still, it has had significant use and has performed and held up well.
I realized Ned asked me a question about the O ring I never answered. My Titans both have perfectly centered O rings, even though one photo made it appear not to be on the Titan Plus. You may recall I was the first to throw both Titans in the water, both as a test and because I have a great deal of confidence in SF(just my opinion-please don't try to tell me how bad they are-I have over 160 lights and in a situation where my life is on the line, I trust them that much). I am not saying that they are always the best( obviously innovation takes time and some companies are A Lot slower than others). Sorry,back to topic: because they are rated IPX-7, and I only did 20 minutes, not 30, there were skeptics. I repeated the test, but got tied up and accidentally let the lights sit, while on, submerged completely for over two hours . Not a drop of condensation or sign of leakage(Sorry Ven, I forgot to take pictures this time).
Still not a single flicker. If I try to change modes 10 times in 2 seconds the light will stutter and stay on low x2 then medium x2. If I change modes like normal use (i.e. 1-2 seconds), it is spot on perfect. In my earlier comparison I mentioned a 4.2v Lithium 10440 would not work in the light. Since then, while in the mountains, I accidentally put a 10440 in and it worked-probably increased output by 50%(visual estimate in very sub-optimal conditions). Lost the low mode, kept med & high. I only used it with the 10440 for around two minutes without problems but heat was significant so I switched to another light. Upon getting home, the 10440 showed 4.02v. After replacing the 10440 with an Eneloop Pro,
Everything works great. The finish has held up well. The detachable tail still works without having felt any less secure, and I feel confident in the pocket clip(I know a couple other CPF'rs had a different experience, YMMV).
I read with interest the "low-low" mentioned above but could not achieve it with the Eneloop Pro. DCcowboyscr, I would recommend calling Surefire(NOT e-mail). I have had excellent customer service from them.
In summary, is it perfect, no, but in my collection of say30-40 AAA lights, it is definitely in the top 10%. I understand others have had a different experience and I am not trying to change their minds or in anyway lessen their dissatisfaction. I draw some of my most influential information from reading the actual life experiences with lights from other CPF'rs, especially those whose experience and objectivity show in their posts. I am trying to emulate those I respect, and I value all input-sometimes a newbie will ask an awesome question no one else has. Thanks to all.)
