Most Helpful Positive Review Best AAA flashlight I know of.
I had it's predecessor, the iTP A3 EOS (96 Lumen version), but didn't like how wimpy the clip was. I had lost one previously due to the worthless clip. The new Olight version has a much more robust clip that is excellent. But I wonder why they dropped the lumens from 96 to 80. I also wonder why they changed the control sequence from the logical low-medium-high to the less logical low-high-moonlight. My only real complaint is the control sequence to get to strobe. Cycling through the control sequence twice to get to strobe is goofy. But considering most people will likely never use strobe, I gu...

The perfect gift!

by Mojo88, from RI, United States Written on March 3, 2015
I have gifted at least 100 of these lights over the past three years. They make the PERFECT gift for ANYONE. Young or old, male or female - everyone just loves this light as a gift. Most people have no idea that such a small light can have such a powerful output. This new version starts in Med mode, then goes HI then Lo. So the modes are Med-Hi-Lo. I kinda preferred the older interface, where it was Lo-Med-Hi. But this new interface is OK. Like I said, these lights are the PERFECT gifts, especially when you are trying to decide what to buy for someone. Just make sure to demonstrate the 'twisty' mode selections to the recipients, otherwise they won't realize the full potential of the light!

My favorite flashlight, period

by Legacy Reviewer, Verified Owner from NY, United States Written on September 20, 2013
I have a weakness for AAA lights (Fenix E05 and E01, Preon P0) but this is my favorite. Great battery life, nice balance between spot and flood, nice color rendition (warm white). Well made and waterproof. Love the multiple modes. I thought the MHL mode order would bother me but not so bad after all. I use Medium most of all and if I need the moonlight mode, I can cover the lnes while I cycle to it. The clip is great but the triangular keychain loop broke almost immediately. Replaced it with small keyring.
Pros: Great battery life, warm white light, nice balance
Cons: Keychain is flimsy - replaced with keyring
