Hi Darren…welcome to BLF! Nice videos.
Dropping videos with no words or introduction and it looks like you might be heavily into amazon affiliate sales…you might like to add your name to this thread where other reviewers are listed and might see attention from vendors: Reviewer List for Manufacturers
The gentleman who started that thread is also a great reviewer if you check out his youtube channel (incredible footage from drones, too…!). I saw your first post about the L21B - he’s the guy who actually created that light with Simon to bring it to market for his hunting customers in New Zealand. Here’s his original thread on that one but there are several others here that discuss the tech and specs, issues, etc: Convoy designed me (us) a hunting flashlight (L21B)
Watched a couple of your videos yesterday. On the L21B thrower battle thing…did you get to compare them at a distance of more than 150m? That’s pretty short for throwers and doesn’t reveal a whole lot. Also, it was good to see your 26800 video with that green cell - curious, though, why did you feel it was necessary or safer to wrap the exposed lower can with kapton? Doesn’t hurt, but there’s no need to really (I’m not sure why those green/blue ones are short-wrapped that way, but I assume it must be for whatever device(s) they were originally intended for…kinda assume they might have been for e-bike or scooters packs, dunno).
Simon also has a long-running Convoy business/discussion/development thread on here that you might like to follow (similar ones from Hank (Emisar/Noctigon), Wurkkos, Sofirn, and several other vendors, too). The title of the thread changes regularly as Simon announces a new something…often the news is in ongoing posts and not updated in the initial post: 【convoy】got some NICHIA 719A R9050 LED sample
