Prompt shipping. Nice looking flashlight, that FL1. Decided to fully charge the battery in a charger first off. It had a starting voltage of 3.45V. An old (crushed positive contact) Zebralight protected 18650 did not work in the flashlight. Neither did a Sony VTC5A or a Panasonic 18650BD protected. The KeepPower protected 3400mAh worked like a charm, maybe because of the button top? Positive connection in flashlight is a pretty small diameter pin maybe a little less diameter of the graphite in a standard pencil? Negative spring looks good and wide. Nice, clear instructions.
Looking at the Amazon listing, just thinking it should be mentioned that Lumencraft is a small business in Missouri. And I did not find an instructional video posted on the Amazon product page, as indicated in the written instructions. No big deal, as it is quite simple. We can see the user interface in action, in the YouTube video explanation for the delay in release, posted earlier in this thread by Lumencraft. It is at minute 2:40.
Reflector reminds me of the fancy PFlexPro option he used to have; nice beam. Typical Cree cast, 6500K? The ramping is neat, with the lowest setting described by Lumencraft as 50 lumens. Yeah, I know this is a bargain/simple flashlight but just can't help describing it. It's nice and look forward to using it during tonight's dog walk.
