I've been out night after night recently trying one against the other ... and have also taken out a number of other lights to give some direct comparison as well ..
Others I've compared them against are Manker E11 (because it's smaller and more pocketable and supposedly will run 100 lm for 11 hrs)
Convoy S2
Manker T01 II
Nitecore MH20GT
Led Lenser both the T7.2 and TT
Niteye / Jetbeam II Pro.
If I had to make a decision here and now between the 2 I originally posted about and could only keep one ... I think it'd have to be the SC62w for core everyday use / dog walking .. it's marginally more pocketable and also unless you need a lot of throw for a specific reason it has a nicer beam closer in for walking in the dark and if 1000 lm isn't enough to highlight something untoward in the distance chances are a slightly better thrower isn't going to make a massive difference and it's time to run anayway.
The SC600 Mk III Hi ... it does have a better throw but not as nice a beam close up for walking and realistically how often do you need to blind someone at 200 plus yds ..... you can argue that it is a happy medium between flood and throw and is still an absolutely amasing light but does it fall between the gaps and there are better flood lights and better throwers (MH20 GT) ... seriously though that's not knocking it - it's still an amasing light and I have absolutely no intention of selling mine.
Comments on other lights in comparison that others may find useful.
Nitecore MH20Gt ... hard core thrower in relative terms to the SC600 Mk III Hi if that's what you're looking for but not nearly so usable for everyday use and not as nice a tint but will always be my number one for shooting at night!!!
Manker E11 ... great light but AA which doesn't have nearly the run time ... one of mine I replaced the LED with an XP-L Hi with a warmer colour and it's amasing and more pocketable than a 18650 ... simply comes down to the run time you want and not quite as bright as a 18650 (but close) against a slightly larger torch.
LED lenser ... They're just S*-t ...
Convoy S2 ... brilliant light .... BUT needs some more modes ... I so often use the ZL's at the mid setting once your eyes adjust to the dark ... if they offered this they could seriously compete at a fraction of the cost but they are quite a bit longer and not nearly so pocketable which is a shame .... maybe I need a short tube version of one
Manker T01 II ... If you want something very pocketable that throws like F*&k for it's size ... this is a great light ... in so many ways I could potentially put this as my number one for all scenarios as the beam is " OK" for general use although the tint could be a smidge better ... I seriously doubt there's anything else in it's size / AA category that will compete in terms of throw so again you're down to run time vs 18650 and some others offer a slightly nicer tint and maybe a slightly nicer all purpose beam but not NEARLY as much throw ...
Niteye / Jetbeam II Pro ... One of the nicest beam profiles of every light I have ... that's also in comparison to the ZL's but we're down to small battery / run time and it is quite a cool white which isn't so appealing but does have the advantage of getting lost in a pocket until you need it (great one for a short walk back from the pub) ... if they could make this exact torch slightly longer to take an 18650 in a similar size to SC 62/63 and a warmer tint than the current one they could have an absolute winner on their hands.
I've also just started cycling again ... following several months off from surgery ... I didn't have a 62 until now and always used to use the SC600 Hi which has been brilliant ... I should be able to try the 62 in the very near future and will post a comparison ... it was on the back of other comments I'd seen in some other threads that I absolutely had to have a 62 to compare it against.
Hope some or any of that's of some use to someone!!!!
