The SC62w in my possession checks out fine as far as I can tell--both aesthetically and for the short term, functionally.
Relying on selfbuilt's review I've been able to master the basic functions, including a reliable switch on to Low. The *tactile* and especially *audible* characteristics of the switch help much for the latter, as I use rhythm/tempo of the downstroke/upstroke of the click to complete the .6 sec hold into Low.
No doubt I'll have to relearn the timing to switch into Low when I come back to the SC62W tonight and for a while after, but its muscle memory and beat timing. With enough use it can become instinctual.
So right now I can easily get into Low/Medium/High, and what I think are two of their sub-levels (hopefully the right term). Strobe and its four sub-levels, and battery test.
I have an idea, but still not completely sure which of what I'm getting below--yet.
High: H1 1000 Lm (PID, approx 2 hr) or H2 620 Lm (PID, approx 2.5 hrs) / 350 Lm (3.9 hrs) / 160 Lm (11 hrs) - Medium: M1 70 Lm (30 hrs) or M2 32 Lm (66 hrs) / 12 Lm (172 hrs) - Low: L1 3.7 Lm (16 days) or L2 0.4 Lm (2.5 months) / 0.06 Lm (4.6 months) / 0.01 Lm (5.5 months)
At this point from where I'm standing experience-wise (zilch) with ZL, this SC62w has set the bar pretty high for my expectations of the four other ZebraLights I have coming in. :O)
