Tynny-13FD Tauchlampe 2200 Lumen

My wife and I are underwater macrophotography hobbyists. We have several dive lights we currently use attached to our camera housing frames, and have owned various models since the early 1990's. The technology has really changed over time. We ordered the Leton Tynny FD13 as a general use dive light to carry in our BCDs or on a wrist strap, not for macro photo use.The product came well packed, and with a zippered case, extra O-rings for the sizes it uses, a small vial of silicone for seal lube, and a sturdy wrist lanyard. It seems well built. I dropped it onto a concrete floor, and it stood up to the abuse with no issues. ;-)I was confused initially about two things:1) There was a quarter-sized round battery shaped object that did not appear to be a battery. Turn out it is a "coin", or more accurately, a "coin blank", or slug to be used for opening the USB-C port cover on the light for charging. There are six settings, including four intensity adjustments, and two flash patterns.2) Use of the wrist lanyard was not initially obvious, but after I contacted Leton customer support, they sent a tutorial screenshot within about an hour explaining how it works. The key seems to be wrapping the strap around the light through the buckle, and then once more around and through it again. The terry cloth side should be up. Worked for me after seeing the diagram.The battery is a robust Panasonic, and charged in under two hours. Runtime was good on the second from the highest intensity level, and lasted over two hours with a significant portion of the battery indicator still to go. Sufficient for a night dive, with some extra to spare.The angle of the light beam this light emits is wide (110 degrees), and should not be mixed up with the "SE" model that is the same price. That light as a very narrow and focused beam, so is likely less useful for general use.Overall, I recommend this as an excellent general use dive light, or as a backup dive light. Hope this helps.
