An amusing note:
So, with the help of the Light.co support folks, I found out how I can transfer 'preview quality' photos to my iPhone 8 Plus while on the road. It takes two cables, the Light L16 charger, and a Lightning to USB 3 Camera Adapter ... a clumsy mess of wires and bits ... until they come out with the WiFi app that's really needed. It works, it's kinda slow, and at least you can do something with the image files other than look at or manipulate them on the camera's display until you get to a macOS or Windows machine with Lumen; better than nothing.
In the meantime, I'd ordered a new iPad Pro 11". Apple has improved so many things in the iPad Pro line with these new models it was simply irresistible ... better keyboard cover, faster IO,
VASTLY more powerful processor,
HUGE RAM and storage (I went for the 1T storage model, which includes an additional 2G RAM over the other ones, for a total of 6G RAM ... raw processing apps fly on this machine!). The 2nd gen Apple Pencil is finally the product I wanted. Et cetera.
One of the first-look negatives, though, is that the 2018 iPad Pro computers now use a USB-C connection rather than the Lightning connection, so I groused about the $100 or so in dongles and cables I needed to buy to connect to my old Mac mini and other things. The plus side, though, is that this is definitely a far faster port and has a lot more future to it, while nearly as compact as the Lightning port.
So I had the new iPad on my desk and the L16 on my desk. The L16 has a USB-C port too. Hmm. I grabbed the standard USB-C to USB-C charger cable in the iPad box and connected them together. No fuss, no muss: The L16's preview JPEG contents are immediately available in Photos for downloading. I selected about a hundred of them ... One hundred 16Mpixel JPEG files were transferred in less than five seconds. Not full resolution or quality, but good enough for on-the-road quickie stuff, etc.
Example:
Spear Plant - Santa Clara 2018

Wow. I can work with that.
