Yep, that's me
I won't be buying the light because of some of my complaints.
What I'd like:
1. Less time before a 1xC becomes a PH. A button click only takes much less than 0.4 seconds. That irritates me.
1a. The time of 0.4 seconds is suitable to determine a series of clicks, the difference between 1xC and 2xC.
2. When the light is on, 1xC is registered when less than 0.4 sec, but a PH is only registered after 1 second? That's not right. There's no reason to wait 1 full second, especially in a situation when you NEED 100% OUTPUT NOW. This is a major issue, IMO.
3. Memory is a feature that (IMO) is very much NOT needed in a light that can be customized to taylor the user's specific needs. Therefore, forcing memory ON when momentary is also ON makes momentary useless to me. Otherwise, it would have been great, having solved the problem I have with waiting for the turn-on delay! There's no delay for momentary, is there?!?! If there is, then that's a major problem!
4. It would be nice if the user could switch between constant and momentary easily, like the D10 and EX10
5. When I want light mode 3, it should take 3 button presses to get there. Like this: 1xC, 1xC within 0.4 sec, 1xC within 0.4 sec. Done. If a delay is required before turning on (and I can understand this) no light should be shown until after the 3rd 1xC.
If I may critique (IMO):
Lower low. I'm not an engineer but am surprised that a PWM regulated light can't be made to go down below a couple of lumens. 1 photon/sec would be nice, but I'll settle for 0.1 lumen.
That would be great, if it's easily done.
Triple click to go back to previous mode. Not a big deal if you've programmed it down to 1-2 modes, but 4-5 mode setups could benefit
No, I don't see this being beneficial. It just doesn't seem like something that needs to be accomodated for an emergency situation. Emergencies require quick access to bright light. If I want to go to dim light, I can take a couple seconds.
Less aggressive crenellated head. Perhaps offer the choice of a different (stainless) bezels that can be screwed in.
Yes. I would like to see "crenellations" like those done on the Fenix T1. Just little "slits" to allow light out, if the light is placed head-down.
Better shock protection. On higher power settings a strong enough shock (eg dropping the torch onto either end from a few inches high) will cause the light to switch off, presumably due to the battery briefly losing contact.
Not sure. If the light can't remain on or tends to change modes from a 4 foot fall, then I would agree. However, the light should not be required to withstand this inconvenience after a 10 foot fall, or something that is otherwise not a simple drop.
More aggressive knurling. The current knurling is more cosmetic than grippy.
Not sure. You know better than I, so I'd have to agree.
Thermal management. No doubt about it, these AA lights get hot on max. Offering optional thermal protection (similar to the optional battery protection) would really push the LF5XT into HDS territory. Of course it means adding totally new sensors to the circuitry...
I don't think I agree... How does thermal management push this light into "HDS territory"?? Does this light dim or fail after remaining on high for extended time? I would agree, only if the light were getting so hot that it was damaging itself. It might be
nice to have better thermal management so I don't burn my little fingers, but if I NEED light, I don't want my flashlight telling me that I have to wait. If I'm willing to burn my fingers to have the light level that I need, then the heat is the least of my worries.
I was hesitant to post this, since I tend to be very particular about my gadgets. I am guessing that most people will say that my ideas are unnecessary and over the top. I really like this light and some of its features. However, with its drawbacks, the light is reduced to "good enough". I am not happy with "good enough".
