Thanks for the quick response. 4x 18650s would indeed make it quite heavy. I’m close to pulling the trigger on a Dive Rite CX2 as a primary light for rec diving. The CX2’s “1700” lumens (even if it’s more like 1400) is likely much more than I’ll need, but I like the idea of trading intensity for battery life. I have a 2x 18650 Nightcore light (non-diving) that I love for its long battery life at 25% or about 400 lumens which works great most of the time for walking the dogs at night (it’s primary purpose). Having the higher intensity comes in handy on occasion. Thinking that strategy may serve me well under water as well.It uses 4x 18650 rechargeable batteries that come with it. You can run it with fewer batteries as well, it just won't run as long. The light is pretty heavy compared to something like a Dive Rite LX20+ for example. Very bright and beefy.
I have a Sofirn SD05 as one of my backups. Can be had for <$40... can't beat it. I prefer it over the DGX lights for example. It uses a single rechargeable 21700.
I'm not sure if I'd recommend the SD01, to be honest, unless you use it with the handle as it comes. It's kind of a large/bulky light and the design could be improved... a lot. The SD05 on the other hand I'd recommend as a 2nd or 3rd backup.
Will check out the smaller Sofirn as a backup. Thanks.
