I guess the EA81 is supposed to be a upgraded model but this EA8 Caveman is much more preferable IMO, anyways, the size weight battery capacity and the overall usage rather in a hurry or taking your time this is surely a flashlight not to be without.

I just got this light for under $60 through the holiday sales. Probably the best buy offered in my opinion. The light will illuminate a barn over 300 yards away. It is for sure a hand held search light. I recommend it.

I purchased this light as an intended upgrade to the Fenix TK41, as both use 8 AA batteries. I'm happy with the EA8, but depending upon what's important to you, the two devices offer different features/advantages:
--The EA8 body is about 1.5 inches shorter than the TK41; the weights are very close.
--The EA8 has 900 lumens in Turbo mode, the TK41 800. I can't tell any difference outdoors visually, either in brightness or throw.
--The EA8 one switch that has multiple modes and half-presses. This interface requires care and practice to make the light behave the way you want. It's manageable, but not simple.
--The TK41 has a simple, two-switch interface; one is the power switch and the other changes the brightness.
--The EA8 has a flashing LED on the switch, which makes it easier to locate in the dark. But you must be in Daily Mode, which requires a gentle, half-press of the switch, and the light can be inadvertently turned on. The light remembers the last setting, so the light could be inadvertently shining at 500+ lumens when this happens. Also, other reviewers have reported that the flashing LED draws enough current to affect battery life. As a remedy, the user can choose lockout mode, but you need to do this each time you turn off the light, and then undo it to turn on the light--not difficult.
--The EA8 comes with a belt holster; this is a useful feature. The TK41 does not.
--The TK41 comes in a hard plastic storage case; the EA8 comes in a thin cardboard box.
--The EA8 has metal, integrated internal chambers for the batteries; the TK41 has a somewhat lightly-constructed plastic battery carrier.
--The EA8 has a useful very low setting (2 lumens) that the TK41 lacks (10 lumen minimum).

Has a smaller hot spot than the EA4, but has a longer throw. I like the moon mode. The EA4 does not have it. There is a greenish tint around the outside of the hot spot. I think an OP reflector would reduce or eliminate this.
