Is it true that the LF3XT has a short runtime on CR123A batterys ?

Thanks, Bruce

This flashlight has multiple brightness levels.


Obviously, the Brighter it burns, the Shorter it lasts.


And, this light has a Wide Range of brightness levels !

I programmed my 5 modes from LOW until about 50%. Btw, the default settings don't go ovr 50% either. You have access to HIGH by doing a PH, so it's a litle bit like the Ra Clicky, where the high is called BOOST and you get access for 10 seconds.

In the CUI, you also get access to HIGH constantly, but that's not recommandable. 50% is enough for normal operation, you may also go up to 75% or so and your battery will be fine, if you reserve HIGH for the situations you really need it.

I don't know if the LF3XT eats the cells quicker on HIGH, my T10C burns out the cell in 45 minutes or so, the Ra Clicky runs 1 hour with 100 lumen, my L4 needs the same time for 2 cells.

If you have the possibility, and with the LF3XT you'll have even plenty of possibilities, always reserve the highest output for the situations you really need it.

Greets,

Henk

Henk Lu said it all

I didn't notice much difference between 66% & 100% on my FUI settings - reprogrammed for 75%. I need the brighter output during day time.

This will give me longer runtime. BTW I have other Cree CR123 lights and I have been putting those cells in the LF3XT at similar output settings to read the battery voltage under load.

Here's the only formal review of the LF3XT that I'm aware of.

http://www.light-reviews.com/liteflux_lf3_xt/

A great place located in the US to buy it is EliteLED.com. Got mine in 3 days.

The runtimes in this review may be flawed. If you read the forum in light-reviews itself, Mev, the reviewer, stated he thought his sample of the lf3 might have been flawed, because it was not as bright as it should be, illustrating this with the same brightness/runtime graph that he posted in his formal review. There is then a discussion of possibly a flawed reflector, which was not the case and finally, he stated that he changed the driver in his LF3XT and it was much brighter.

However, I don't believe he reran the runtimes, in spite of the fact they didn't look quite as good as the LF5XT and there could have been a problem when he did his runtime tests with a different driver.
In any case, his reviw doesn't state in the summation of badpoints, that runtime was an issue.

I finally drained the last erg from the first battery I've run through the light. Had just enough time to get a battery report before it switched off. It said 1.5 v. At this point the same battery would not fire up a P2D at all, but would continue to give a useless glow in an L1. So, it seems the LF3XT is a good battery drainer.

Yes, this was a primary battery. I don't use rechargeable CR123s, yet. I know most folks may not be as cheap as me (it's my Scottish and German heritage). :laughing:

lol, that is ok , some people dont understand me and im american

so are u stating it has good runtime? how long did that battery actually last?

thanks

btw, i think i am going to buy one , lol i am still awaiting my jetbeam military , then i will make my decision on this one, lol its a sickness , lol

Sorry, I guess my post was kind of out of place, since it really had nothing to do with actual runtime. It just seemed related. I don't know how long in total the light ran. Since getting it I've probably turned it on and off hundreds of times. :shakehead

Babydoc, where are you getting this info?
In that thread on light-reviews.com forum it was clearly stated it was a flawed reflector which was why the review was held off until a proper one was provided. The review published was of the corrected reflector retail version of the LF3XT and latest driver.

And where are you getting this info on bad runtime with different driver? It was simply a decision by LiteFlux to revise the driver in the updated version to boost overall brightness.

sounds like to me he owns the light and loves it and has bought many that dont compare, why is it ingorant because he doesnt want people to get the wrong impression that this is a battery killer ?

to me when someone calling someone else ingnorant it shows there ignorance (u couldnt have simply replied maybe u read light reviews differently than i did and state your case ,, all your reply sounds like to me is u are picking a fight and i doubt people on this baord really appreciates that)

just stating what i read from u as being very strong and mean sounding

Madi05 is right, Splunk. That was really uncalled for. You've been around this forum long enough to know we don't do insults or name calling. An apology is in order.

Splunk_Au,

You're correct in the facts of what Mev posted, but like others, I do agree you were a bit harsh on BabyDoc. He's been posting some really good info on the LF3XT, and in a quite detailed manner, I might add. Ease up a bit, please. :)
