I have the EA4W and EA8W.
Lightliker, so far I have found two main benefits of the EA8: 1) Extended runtime on turbo (no apparent stepdown), and 2) the lowest level is nice and low.
There are other benefits, like the increased-brightness blue indicator button, better mode spacing, and farther-throwing beam, but I am not including them.
A big downside for me is the 8 batteries, the heavy weight, and the huge length.
There is just something so appealing and novel about the EA4.
I love my EA8 and I admire it for many reasons, but if I was forced to choose one, it would be the little EA4. There's just something so appealing about a 4X AA light, the size of a toilet paper roll, which quickly punches out a nice beam. The EA8 is a bit more unwieldy... For example, I am going camping this weekend and cannot see myself bringing the EA8 with me. The little EA4, on the other hand, will be an awesome compact searchlight
