Whether it's worth a shyte, I'll add 2 cents here. My HDS has spoilt meh, especially after a 18650 tube, oof (but only clicky style, no rotary for me yet). Now a MD2 is also carried around by myself. After years of programming I can appreciate a forward click and head twist, you know what I mean. KISS makes lasting impressions on a device. I like to own lasting products if I can. I don't come to CPF often due to no interest in current lights. Precursor has been set.
Now, awhile back I bought my wife a Fenix EO1 as a key chain light for her purse. That rode around for a long time. One day we turn it on and it's dead. I just recently replaced this light with a Peak Eiger Ultra. I am highly impressed with this Peak. Made in USA which I like, epoxy head for durability, the light is turned on via a head twist. QTC technology, as material is compressed more electricity flows, allows the light to ramp from dim to bright. It's not perfect and there is some flickering, but it still ramps. Fast twist gives full bright. One option of light has no tail switch, and the other option has a keychain end that can be replaced with a momentary button. Very simplistic and I'm sure a long running item.
Were I to get a AA light I would get the Peak LED Logan with 17500 tube and have access to a whole bunch of battery types. This light wouldn't be for any like "tactical" carry, just good ole general purpose. Put it in anyone's hand and they will figure it out.
