Even with the LF3XT set up for momentary it might still come on, since all it takes is that quick pop (C) to turn it on constant. Maybe they're working on a stiffer spring under the switch cap, but auto-off too would be nicer.

Another idea for those experiencing problems with your light turning on is to leave it set to the lowest possible level, that way if it does accidentally come on it won't get hot or burn the battery down very much.
My LF2X gives more than twice of that. I have measured it to 149 lumens, but I am working on improving my measurements so it may change a little. At 100 % it gets so hot after a few minutes that i have to make the measurements quite fast.

Being that it gets that hot, is there a concern if one uses the diffuser, being that it is only plastic?

That heat was probably being generated with a Li-Ion battery. Don't think there'd be any problems with Ni-MH or others. Of course, it wouldn't be that bright either.

Yes, that is right, it was with a Li-ion battery, and run at 100 %. I do not think this is a mode that should be used over longer time, with or without diffuser. I guess the diffuser would also make the conditions worse for the led.

Yes, while this little jewel will get super bright using a lithium-ion cell, the laws of physics still apply.... and all that extra heat has to go somewhere, so the only way I've done runtime tests with my light at maximum using a lithium-ion cell (after being sure that the light's low voltage indicator/shut off system was turned on), is to place the light in a cool glass of water first.
It's great for that WOW factor (30 seconds at a time)..... but most of the time I have no need to run my light at over 65% max output (using a lithium-ion cell), which is about 80 lumens with my Rebel LED.

LiteFlux has listened to your valuable input and will consider implementing an auto-off function in the LF2XT (provided there is any memory left in the MCU)
this auto-off function can be turn ON or OFF by the user.
in your opinion, what would the optimum time period for the LF2XT to switch off itself when there is no pressing on the electronic tac switch?
30 seconds? 1 minute? 2 minutes? 3 minutes? 5 minutes?
i, personally, think 2 minutes should be good.
your suggestion would be much appreciated.
thank you.

That's great news Liteflux is listening and thanks Khoo for letting us in on this. I'm inclined to think 5 minutes would be better. If I'm using a light much doing tasks or even just getting up in the night I find 5 minutes works best and when I'm done I just set the flashlight down to let it turn itself off. Anything shorter I think would get annoying to have to keep pressing a button to keep it on if you were for example outside looking around in the night. Now if it could be easily disabled / enabled with only a few clicks or presses than maybe a shorter time would be okay. But I've got one light that has a 5 minute shutdown and it seems just right. Those are my initial thoughts but I'm open to being persuaded otherwise :thinking:

This sounds good.
I believe 5 minutes is better, but the auto off must be careful implemented, it can not just switch the light off, it has to fade slowly to off (slowly is maybe 30 seconds) and any press on the switch will restore it to previous output and reset the auto off timer.

That sounds nice. I do find the 5min on the NT just a little long, when it is an accidental activation, but during use I like it because it is out of the way. I'm sure 30sec would be way to short to keep having to click the switch to keep it lit. Given LF2XT will be much smaller than NT, and thus have less heat dissapating ability, a 3min shut down seems pretty good. I'd be willing to try 2min also since it is the type of light I would likely use in short bursts. If it can handle the heat on high for 3min though I would suggest that.
As with the NT before it shuts off it should give some sort of clearly identifiable signal with enough time to hit the switch before it turns off.
Looking forward to see what they come up with.

Five minutes would be a bit long considering some will configure the light to first come on high. If it turns on in a pocket, that seems a long time without the benefit of hand cooling, especially if running a 10440.
In the interest of protecting the emitter, and battery, I vote for two minutes, three maximum. Wouldn't that be the main benefit of auto-off in the first place? It could also protect your leg, hand, and quite possibly the entire light itself. Imagine this scenario if you will...
Hey, why is my leg burning? Oh No! My LF2XT is on!... go to grab it... OW, my hand! Light drops head first onto concrete. Nicks, cracked lens, etc.
For purposeful use lasting any real length of time, just take the light out of auto-off, and put it back in when done.
Two minutes sounds best to me. :thumbsup:

If it's in the pocket, wouldn't that accidentally swtich it back on again and again? :thinking:
I agree. I've accidentally on EDCs in my pocket before, after one minute it gets warm to the point you can feel the heat on your thigh. For another 4 more minutes, I'll have a fried chicken thigh.

if it get switches on that often in the pocket, it does not belong there!
I am thinking about using the light, I want a easy way to restore full output and want time enough to do it, even if I have put the light down.
A shorter time on real high power would be fine.

Then a lockout function would be better. That could be implemented as 3 fast clicks to turn on.
I.e. enable "lockout" and the light always requires 3 fast clicks to turn off, this would also prevent any mishaps in a bag or pocket.
If I use the auto-off, I do not want to take the light out of that for normal use.

Two minutes max sounds OK to me. If I find that it is easily activated in my pocket, I'll likely lock it out like I have to do to my LF3XT.

+1 sounds good
Would be great, unless your light is at the lowest setting, then how could it fade slowly to off?:shrug:
Lol!:twothumbs
:thumbsup: I agree! Just hope it will be easy and fast to switch the auto-off on and off.
