    Default *1894 hr Update* L1-RD (L1 Red) ~vs~ X5 Red ~vs~ 24/7

    *1894 Hour(78 Days) Update...see last post*

    Alright...finished my L1-Rd runtime test, and after some forethought, decided to pit all 3 of these light together. All 3 were given fresh (3.25 volt) Surefire CR123's.

    The L1-Rd will be ran on low, and the 24/7 will only be used on the red setting.

    After power up, the X5 was the brightest of the 3, and the 24/7 the lowest. the most USEFUL of the 3 was the 24/7, providing the most flood.

    So...which will win out? Not the longest running, per-se, but the one that will run the longest with useful runtime. Let's here your hypothesis. Who will win? Let's get your bets!

    1) 5th Gen L1-RD

    The Runtime on the 5th Gen L1-Rd went like this (No science, just real world use)

    Runtime Cut-off: 114 hours (it was putting out useless levels light and wasn't making any considerable drop's in out-put)

    *This is the 2nd runtime test for the L1, and I have left it on well past the 114 hour mark. I can still use the L1 for reading a map, and minor navigation (I can still use it for going #1 in the middle of the night, and I'll leave it at that)

    Max Out put (Max light out-put): 0-12 hours
    Prime out-put (Easily Navigate a pitch black room): 13-75 hours
    Minimal Out (Can easily read a map/navigation doable, but not recommended): 75-94 hours
    Negligible Out-out (Can read a map, but not comfortable): 94-100
    Unusable Out-Put: 100-??? (I cut it off at 114)
    -----------------------------------------------------------------------------------------------------------
    *168hr (1 week)*

    167 hours...X5 is uselss except for very upclose reading...can't see anything further thna 3-4". The L1 can still be easily used for map reading and some navigation in a pitch black environment. The two have been running for a week straight, and it looks like the L1 has won this run off. I'll leave them both running for the sake of it, but am done reporting on the X5 (although I will post a time when it shut's off...as long as it's not for another week). Same with the L1, although I'll probably shut that off when I can no longer read a map with it.

    -----------------------------------------------------------------------------------------------------------
    *250 hour update*

    X5: 1.88 volts: Still just a glow, can't see anything past 1-2". (Note, the X5 was inadvertently shut-off for about 16 hours, so it's actually at the 230'ish mark, and the voltage would be lower)

    L1: can still be used comfortably as a reading light in dark environments (Maps/Books/Circuit Breaker, etc.)

    The L1 is taking this one by storm, and still puts out 3-4 times the light of the X5 at the same voltage.
    ------------------------------------------------------------------------------------------------------------

    *365 hour update (15 Days)*

    The X5 is still glowing, but is useless. The L1 took another dip in out-put, and is only good for up close reading, but is still just a hair brighter than the X5. Will have voltage readings shortly.

    Default Re: L1-RD (L1 Red) ~vs~ X5 Red ~vs~ 24/7

    I posted this in the other thread, but I'll put it here for posterity:

    "I'm guessing both of them will last ridiculously long regardless of which one 'wins'... though I'll throw in a vote for the X5 to beat the L1 by half a day to a full day.

    When I had a red X5, I was never able to complete an acutal runtime test since I liked using the light so much.

    I did recently put in a XRE R2 into an old Nuwai Q3. Converted it to direct drive and use a nickle has a heatsink. Run direct drive off a CR123, it ran from Tuesday @ 4:30pm through the next Tuesday @ 11am when it seemed to completely shut off. If I leave it turned off for a half hour, it will light back up with enough light to read by. I checked the pull at the tailcap every evening. Overall, it slowly dropped over the first three days, then provided maybe 6 or 8 lumens for the next three days then trickled off to the 1 lumen range for the last day. I'm guessing the red X5 will act the same, but won't last quite as long as I'd suspect the five 5mm LEDs will pull more than the single XRE."

    No idea on the 24/7.

    Thanks cratz! Yeah, after starting the other two, I was like 'Why not do the 24/7?"...so, I added that into the mix. I think the L1 may win this one though, due to the X5 being brighter right off the bat, it may be pulling more juice, and have a sharper drop than the L1? But, that's why I'm doing this. This is one of the most requested runtimes on CPF, and no-one has ever had the patience. I will admit, I miss being able to properly "use" my L1 (or my X5)...sigh...It'll get interesting after the initial drop starts.

    This is great!! Are not multiple LEDs more efficient, though? The X5 may edge out based on this. Either way AOW, I just picked up the sister X5 to yours, so this is a timely test for sure!

    Yeah, that's kind of where I'm coming from... If it were a 'to 50% brightness' runtime test, I'd probably lean towards the L1 over the X5, but I'm guessing that the five 5mm LEDs will be able to churn out more 'barely enough light to navigate in a cave' amount of light longer than will the L1.

    Either way, they are both winners before the test even starts!

    Actually, when are you going to consider the light to be longer usable? When each of them reads 100 or 114?

    Not sure what you're asking the cratz??? Lumen out-put is not being measured during this, just runtime. How "useful" it is is just me comparing them to each other at any given runtime (i.e. a side by side comparison of the three at the same run time with the same fresh cells), giving the community an idea of the best "Red Battery Vampire", or help them pick which best would suit their needs.



    That said, here's what I'm seeing at the 10 hour mark:

    *L1-Red: No real change from initial output; Now the L1 is brighter than the X5, showing how fast the "initial brightness" of the X5 runs down

    *X5: Just a bit dimmer than the L1 now, but still very usable amounts of light; Brighter than the 24/7

    *24/7: No real change in brightness.

    Hmmm...13 hours, and the X5 has dimmed even more...but, it may be able to hold on there once the L1 makes it's initial drop.

    24-Hour update (24hrs 23 mins)

    Hmmm...not looking good for the X5. Here's current voltage readings on the cells:

    L1: 2.72 (1ea. 3-Watt Cree driven at 1-Watt)
    X5: 1.88 (5ea. 5mm)
    24/7: 2.76 (2ea. 5mm)

    Brightness (in order of Brightness):

    1) L1
    2) 24/7
    3) X5

    Looks like those 5mm's are wasting alot of energy...will get some beam shots up soon.

    @PSM, YEP!!! I was kinda up in the air that the X5 might beat the L1, but it's not looking to promising for the X5 right now...

    Voltage Update (36 Hours {2:03PM EST})

    X5: 1.83 (Useless level of light for navigating)
    24/7: 2.34 (Not much different than it was from start, still very navigable amounts of light being produced; Brighter than X5)
    L1: 2.24 (Still putting out plenty of light, as seen from previous runtime test)

    Default Re: *24HR. UPDATE* L1-RD (L1 Red) ~vs~ X5 Red ~vs~ 24/7

    48 Hour Update:

    L1: 2.04; Now starting to dim; still plenty of light on low for easy navigation; will still go into high, but not nearly as bright
    X5: 1.78; Still dimming, and a lot dimmer than the L1, but you can still navigate a little with it
    24/7: 2.05; Light is dead; light shut off around 45 hour mark, but it died with providing plenty of navigable light. There was no "dimming" per-se, but rather it just shut-off. Came back on after a few seconds of rest and I'll leave it running and see when it shuts back off.

    About the 49-50 hour mark, the X5 took another big drop, and is no longer useable for navigation, and is barely usable as a reading light.

    Wow... I definitely would have guessed MUCH longer than ~50 hours for the X5.

    Yer welcome PSM...I know which one I will take when the Zombies come now. I had high hopes for the X5 after reading all the hype. It's a great battery vampire/drainer, but for a red LED light, the runtime kinda sucks...L1 all the way! I'm sure this thread will get alot of views over the years though, so I know my effort wasn't in vain. I (and several other CPF'ers) always wanted to know the "real" runtime of the these lights, so, I put the final nailin the coffin. Just wish I had my 5th gen L1 white head back so I could do a side-by-side of the L1-RD/L1-Wh. I'll definitely pick up another 5th gen L1-Wh next time I have some extra funds though.

    Just found this thread- Nicely done! makes me want to run my 4 flats Milky Floodmaster on low to see if it'll go as long. Great runtime on the red!!! Thanks for doing this. Do you know if there are efficiency differences between the older L1's and the newer generations?

    I think the newer L1's are rated for 16 hours on low, while the older were rated for 90 hours.

    Have you tried the L1 with Surefire's available beam diffuser? It works really well on my red KL1.

    2nd generation red KL1 with Surefire F04 beam filter. Provides a perfectly smooth beam with lots of flood.



    The most useful lights are the ones that provide a deep red output. Your L1 appears to have a better deep red output than the 5mm LED's of the Inova, which is not surprising. To me it's not so much about having brightness, but preserving night vision.

    Can anyone determine which generation this L1 is? 3 watt LED, 22 lumens high (white) for 4 hours, 1.1 lumens low (red) for 90 hours.

    Thanks for any help.

    Yes, and it's a nice combo! In fact, it's so nice, I went ahead and "permanently" diffused my L1-Red with some glass frost. Also did that to my Kroma Mil-Spec...Much better now!

    Well said Ampdude! That's why my L1's never get fresh cells (minus a runtime test, of course). They really are too bright, and as you said, it's about preserving night vision more than anything. Yeah, the 5mm's on my X5 aren't nearly as "red" as my L1-Rd.

    *250 hour update*

    X5: 1.88 volts: Still just a glow, can't see anything past 1-2". (Note, the X5 was inadvertently shut-off for about 16 hours, so it's actually at the 230'ish mark, and the voltage would be lower)

    L1: can still be used comfortably as a reading light in dark environments (Maps/Books/Circuit Breaker, etc.)

    The L1 is taking this one by storm, and still puts out 3-4 times the light of the X5 at the same voltage.

    Huh??? A red AND white L1? May be a Milky mod??? They never came that way stock, AFAIK....But, based on the runtime numbers, that would make it a 4th or 5th gen L1, with the current (NOW DISCONTINUED... ) gen being the 6th.
