    Bravo, Fenix! I just ordered the LD02 V2.0 yesterday to try out myself to see if it will be adequate for friends without lights that are in the medical profession. Now I see the LD05 V2.0 will be a better tool for these nurses I have in mind. Hope the stock lasts on these, as I won't be able to order more for at least another month. Eventually, I'll be ordering at least two LD05 V2.0 for lab coat breast pockets for those I have in mind, and possibly two more after that for the same reason, exceptional medical pros that make a positive difference in my life.

    My list of favorite features that are rare among all flashlights, and none but Fenix have them all:
    • Constant Current circuits
    • Regulated Brightness
    • Mode Memory (surprise!)
    • Reverse Polarity Protection
    • Tail clicky for easy one-handed operation
    • Built-in permanent pocket clip
    • High CRI 3000K emitter, excellent color renditioning for patient examination
    • 2 hours of 100 lumens, nearly 7 hours of 25 lumens, 36 hours of 5 lumens
    • secondary UV 365nm emitter (possibly a decent vein-finder)


    I hope this is a developing and lasting trend in the flashlight world, that aside from Fenix, seems to be have stagnated on cheaper PWM-laden drivers and boring, blinding, poor color rendering, often green-casted cool white emitters (though Fenix's standard CW stand out as pure white among those).

    Thanks for taking the risk, Fenix!

    I must say this is impressive! Well done Fenix.

    Thank you for your kind words. Please check the updated LD02 vs. LD05 comparison chart above. We moved that stinkin' little decimal place over on the diameter size.

    My LD02 V2.0 arrived moments ago. The TIR casts an unexpectedly tight beam. The 3000K HighCRI emitter really illuminates nearly just like an incandescent lamp... attenuates color, makes flesh tones appear natural, and it is very easy on the eyes. The cast is decidedly not "yellow," but it is better described as warm. And surprise, there is an unmentioned secret feature: mode memory. Mode memory solves some vague concern I had (for a light with two very different emitters) when I assumed the driver would always start in low. Instead, the mode remains on the level where it was when switched-off. I'm on the fence about whether to gift this one or keep for myself. I'm definitely buying more to gift... just not sure I can let go of this one. I am not proud.

    So if it has mode memory does that mean you have to cycle through UV every time you adjust settings (eg Med to low). That's kinda dumb.

    Yes, that's what it means, but I don't see how whether it has mode memory or not could change the fact that there are 4 modes, L-M-H-UV. The modes only advance from 1st mode to 2nd mode, 3rd mode, etc. You can't go directly from medium to low, nor advance the modes in reverse. The sequence is what it is, and most other AAA lights I know only forward advance the modes. I can't imagine any other way it could be, other than always starting in low. I think having mode memory is better in this case (having dual spectrum emitters), rather than always starting in low (no mode memory).

    Knowing it has mode memory, you can always set the mode before turning it off to be in the mode you wish it to be when you next activate it, whether immediately or minutes, hours, or days later. The driver remembers the mode you last used when you last switched-off, even across a battery swap, and when you switch it on again, it comes on in that mode. Clicking the light off and on generally does not advance modes (unless madly clicking off and on as fast as possible). The modes only forward advance when the light is on and with a touch or half-press of the switch.

    For example, if you are using UV, and you turn the light off, when you turn it back on, it will still be in the UV mode. To leave UV mode, from on, you half-press the switch to get to low, half-press again to medium, half-press again to high, half-press again to UV, etc. What ever mode it is in when you turn the light off, it will be in that mode the next time you turn the light on... this is pretty much by definition what mode memory is.

    The only lights I ever used that allowed reverse advancing modes were the BLF (Astrolux) X5 and X6 with toykeeper's firmware interface, where half-pressing the switch quickly advanced forward through the modes, and holding a half-press for a second reverse advanced the modes. Those lights are much larger, have a big button with more travel. LD02 V2.0 is a small light, with a tiny button, and less button travel, so while duplicating that schema in this light is likely possible, it is probably not practical because it would require quite a supple digital dexterity.

    Itís not 100 lumens for 1 hour and 40 minutes or 2 hours and 10 minutes. Itís 100 lumens for maybe five minutes, then it drops to 60 lumens for the rest of its runtime.
    Even 25 lumen mode looks like itís down to about 15 lumens after about 15 minutes and stays there for the rest of the runtime.

    I think I see your point clearly, and I am forced to agree: 500-1200mAh AAA cells are inadequate. What we need are at least 2000mAh AAA cells, and more! Why has the development of higher capacity AAA cells stagnated? I'm writing my congressman right now to report this, and demand higher capacity AAA cells, and suggest all do the same. This outrage will not stand.

    Why don't they just make a 2 x 21700 version of this or 2 x 26650 version? It doesn't make any sense!

    Oh wait... PEN light. Priority is to the size, not the function.
