> what’s the biggest difference between the regular model and the newer edc model?
about the ZeusRay — it’s being figured out, have a look at the thread about it as the news comes in there:
There are other zoomies, if you want to keep this topic as a general one for suggestions.
How big a light do you want? AAA, 3xAAA, AA cells ok? Or do you expect to use lithium-ion?
How about D-cells, or 26650 cells?
Narrow down what you’re looking for a bit — have you put “zoom” in the search box (upper left corner of the page) and sorted by date?
That will suggest a lot, and you can narrow that search effectively by adding other terms.
Besides using the BLF search here, there’s always 26650 zoom flashlight - Google Search
or searching for “3xD zoom flashlight” turns up stuff like
