is ZL going out of business or what
At least, this time, I get the sarcasm.
Chillin finally said something I do agree with: 14500 in SC53 "why mess around". I get why you guys are, but, personally, too many problems /risks for me to bother. One that bothered me with even the 52 is that I think the can (or neg terminal anyway) of a 14500 is thinner than an eneloop, and that spring grinds in a pretty nice groove. At one point I was paranoid enough to tape some brass shim on the bottom. Also, in the 52 days, it was a Sanyo UR 14500, and the new ones (even 800mAh) are significantly more capacious (Wh & Ah). I also worry about the NiMH-useful crushing pressure of that spring can't be good for the positive terminal of a 14500, be it flat or button.
I guess that makes my biggest ZL wish, over any UI or aesthetic considerations, to be (physically) nicer to my batteries. And a clip I can take on and off my H53 without scratching the finish. Ditto the Sofirn SC21. Really, can't someone come up with a better way to attach a (removable) clip to a cylinder, in general?
Blue light and melatonin: I thought that theory didn't hold up to more recent tests. Last I heard was that it was what you were doing with your blue light sources (usually phone/computer LCDs) that got in the way of sleep, more than (or entirely instead of) the spectrum. Read that somewhere, IDK. As far as micro-lumen nightlights, I think a 0.01lm blue light is gonna be exactly the same, sleep wise, as whatever the warm white equivalent is. It's all rod cells, anyway, at that level. And, it's amazing how little blue/cyan light it takes to be able to distinguish a dog bone from a dark floor on the way to the loo.
THANKS for the 198lm test. I was wondering about some of those ZL runtimes. The lumens, at least, I trust. Well, until the 53n - I have serious doubts about the top levels (differences between, mostly, and only on NiMH). My gripe is M1 vs M2. Double lumens and a 8.5h vs 21h runtime? Something is off (I think the claim of 8). Seems like a really big jump in brightness (and tailcap current), not just a doubling.
Looking forward to ZL going out of business and then popping back up with the Nichia 18650 model. I'll definitely set some $ aside for that.
