    Thrunite is going to release a new lightsaber

    My colorimeter says the HC20 is 4800K (x=.352, y=.368). It looks positively lovely compared to my ugly CW Sunwayman D40A that is a awful 7200K (x=.304, y=.312). During daylight hours now in the house it doesn't seem as cool as it did last night.

    Thrunite is going to release a new lightsaber

    Well, I can partially answer my own question. I received my "neutral white" TC20 yesterday. It's pretty cool. IMHO, it's at the very far end of what I'd consider "neutral". It's cooler than every other NW light I have. It's not as cool as a CW light, but it's not too far off. If it were...

    Looking for a small keychain flashlight

    FWIW, mine has about 6 months of life on my keychain. So far so good.

    Looking for a small keychain flashlight

    I've also switched to a TIP on my keychain. The 2017 CRI one. Previously I was EDC'ing a 4Sevens Ti Quark Mini (CR2) for many years.

    Triples/quads are on their way out...

    So how would you compare that to a false prophet? :whistle:

    Thrunite is going to release a new lightsaber

    Any idea on what their definition of NW is? 4500K? 5000K?

    Losing a flashlight stinks

    Losing your EDC is an excuse to upgrade right? :twothumbs Mine is attached to my keychain though, so I haven't lost it yet.

    Bought many $3 Chinese single AA zooms. What am I missing?

    Because the excess length of an 18650 is a new development right? There's no way a flashlight maker could have known about it and factored it into their design. :shakehead

    Gearbest

    I did because DHL shipping on my L6 was like an extra $1.40 vs. the slow shipping.

    SkyRC — IFA 2014 — MC3000 charger-analyzer

    Or apparently a rectangular block labeled MC3000 moving around the screen with a ball bouncing around off the edges and the moving block as well. Yes, I agree. If you're on grid the charging efficiency is a who cares. If you're off grid working out of a backpack with a small solar panel and...

    USB powered 4xAA (independent) analyzing charger

    How it their math? Xiaomi says it has 10Ah capacity. It likely does at the voltage of the internal batteries. It could have 10Ah of NiMH batteries in parallel at 1.2V or 10Ah of SLA at 12V. You're measuring the mAh of a 5V output. The output voltage is different from the internal battery...

    USB powered 4xAA (independent) analyzing charger

    I think your math is off. That's 10Ah at ~3.7V, so 37Wh. 6.25Ah at 5V = 31.25Wh. Basically 84.5% efficient to the USB output.
