Fenix L0P-SE runtimes

[chevrofreak]

Well, here they are, the Fenix L0P-SE runtimes, high, medium, and low.

And all three together on one graph.

Compared to the original L0P. This is based solely on throw, but should be pretty close since they use the same reflector.

Before anyone asks, the way I did the medium and low L0P-SE runtimes was different than the way I did the MillerMods L0P ones. I had the light a lot closer to the sensor to get a smoother line as it dimmed*, then using my typical method adjusted the numbers so they matched my sphere readings. The MillerMods L0P never did make it into the sphere since I hadn't built it yet. I can compare the High of the L0P-SE to the Millermods L0P since they were both done at the same distance but the output numbers can be varied due to the light not being aligned right to the sensor. You'll just have to try to extrapolate the data from there.

*when it dims and the light is further from the meter it makes the line look blocky/stepped

Great job on the graphs chevro! Those energizer E2 lithiums blow away the others. I never knew how much better they were than duracell.

You might have sold me on one of those LOP-SE's. Looks like a lot of bang for the buck. Most of the other reviews seem to be very positive also. Nice work.

Yup, those lithium cells sure do hold a lot of power and handle the current well. I think they actually have more of an advantage in AAA size than they do in AA size.

Also, here are my measured light output numbers for each level and cell. The numbers were taken at the very start of the run.

Fenix L0P-SE - high - Energizer E2 lithium: 438 - (est 31.29 lumens)
Fenix L0P-SE - high - Duracell Coppertop: 380 - (est 27.14 lumens)
Fenix L0P-SE - high - Sanyo HR-4U 900mAh Ni-MH: 380 - (est 27.14 lumens)
Fenix L0P-SE - medium - Energizer E2 lithium: 147 - (est 10.5 lumens)
Fenix L0P-SE - medium - Duracell Coppertop: 133 - (est 9.5 lumens)
Fenix L0P-SE - medium - Sanyo HR-4U 900mAh Ni-MH: 131 - (est 9.36 lumens)
Fenix L0P-SE - low - Energizer E2 lithium: 63 - (est 4.5 lumens)
Fenix L0P-SE - low - Duracell Coppertop: 59 - (est 4.21 lumens)
Fenix L0P-SE - low - Sanyo HR-4U 900mAh Ni-MH: 56 - (est 4.0 lumens)

Thanks for compiling this excellent data chevro!! It's good to see that Fenix was close with their lumen estimates on this one.

Thank you, great graghs chevro! Looks like Fenix is geting more on target with thier lumen claims. Brighter than the older model but with shorter run time. That Miller mod really cranks.

Runtimes are pretty good on all levels, for an all in one light. I`m impressed. The E1 and E0 still have there place with better runtimes and regulation. Not sure what the future holds for the basic L0P. Seems like for a few extra dollars you get so much more with the SE. Nice light.

Chevrofreak, thank you for the excellent data. Just when I became curious about the L0P-SE, I looked, and there it was.:thanks:

Thanks, chevro. That's alot of work for the team. You deserve a beer or three.

Thanks, chevro. Great charts! Looking forward to mine even more now (2nd batch shipping Monday). All we need now is a great sale somewhere on E2 AAAs....

Shopko, 4 packs of AA and AAA are marked down to $8.99 and theres a $2 rebate. It's probably a mail in rebate rather than instant though, and I think it's a limit of 1.

Buying 8 packs can drop the per cell cost quite a bit too, I think it's something like $15.88 at Walmart.

crap, I posted under the wrong username again!

Thanks Chevro!

Without a doubt, its really hard to justify an Arc-P when you see these numbers and compare prices. I have to say this year Fenix has hit a few out of the park when it comes to price to performance on LEDs. $20 gets you double the runtime at half the cost for an E0 vs. Arc-P. Or for about the same cost you get a white Luxeon at 3 brightness levels vs. an expensive angry blue Nichia CS.

Very nice! I love innovation and competition!!

Could anyone with experience (chevro perhaps) give me their opinion on using NiMH in the L0P SE? Will the light overdraw the battery easily and kill it prematurely? Once you see the output starting to dim, is it too late? Also, being a twisty, how about long term durability for the NiMH cell- will the friction of all that on/off damage the battery? Thanks in advance for the opinions/answers.

Cheers to chevro for the great runtime graphs- thanks so much for your work.

 

[chevrofreak]

It is capable of taking a Ni-MH down to the damaging levels, but it will be very dim before it gets there. I accidentaly left it running on a Ni-MH until it was .875 volts which is in the dangerously low area. The cell seems to have not suffered any damage though. I believe it was the Ni-MH run in the High graph I'm talking about, you can see that I let it run too long.

Thanks for the runtimes. I would like to see a longer runtime on the lowest mode though. Maybe Fenix could bump the lowest setting down to 1 lumen so it can run over 12 hours.

Personally I think that would be awesome provided the PWM isn't too noticeable. I can deal with it when reading with my JetBeam if all is still, but the slightest bump or shake and it gets annoying pretty fast. I am one of the proponents of a very low low though. With dark adapted eyes, 1 lumen is plenty for closeup work with out drawing too much attention from others and totally ruining night vision.

thanks chev!

I've been waiting for these. Can't thank you enough. :thumbsup:

Thank you chevrofreak, great work again.

Thanks for the tip---looks good for folks with a Shopkos nearby. Unfortunately, no Shopkos in my state (Texas). I didn't see on the webpage that they would do online orders.

However, I did remember that I had this deal on E2 AAAs saved in my Favorites---$8.99 + free ship (CONUSA---Sigman won't like this!) (+ no tax): http://store.batteryspecialists.com/l92bp4.html

Haven't dealt with them yet, so can't vouch for them.

Awesome graphs Chevro!!! This thing rocks on a lithium! I've been running mine on my duracells rechargables, but I'm gonna go pick up some lithiums from Wallys world today. Thanks
