Haiku(s) and Sundrop 3s runtime test... Includes Per-Sev's 2xAA Haiku test.

[scout24]

On the heels of last week's wildly successful LS20 runtime tests done by JBlackwood and myself, here comes the Haiku and Sundrop3s runtime test. Left to right, BB Haiku XR-E, Haiku XP-G, Sundrop 3s, and McLuxIIIT S Mizer, conversion done by Don, used as a control only. All lights on low level, BNIB Surefire primaries dated 10-2018. Turned on at 12:30 PM here in NY, I will monitor every few hours until dimming compared to McLux, and then until flickering. Enjoy! One thing I found interesting. This was the first time I put the Haiku's side by side while on, and the XP-G has a narrower beam profile, even though the beam is smoother in coverage side to side...

7 1/2 hours in, everyone is going strong... not even warm to the touch... :candle:

Thanks for taking on this project.
I will be following this for sure.

I guess there's no direct way to find the runtime except by actually burning batteries, but I think for practical purposes measuring the current and calculating a runtime estimate would have been enough.

Awesome!!! Looking foward to results...

My money is on the SunDrop FTW :thumbsup:.

Re: Haiku(s) and Sundrop 3s runtime test...

They (3S powered lights) should all be around the same I would guess...

21 hours in, not a drop in output yet, at least as far as the eyes are concerned. Still even with McLuxIII as far as output, not scientific, I suppose, but real-world. Nice to know the theoretical, but nothing beats hands on, as far as I am concerned. As they say, confidence in your gear is the result of actually using it. I do wish I had brought my Fluke home from work to measure voltage at the end, but hindsight is 20-20... More to come.

Awesome!!
thanks for sharing Scout24,curious to see the results.

26 1/2 hours, no visible drop, everyone still going strong...:thumbsup:

Re: Haiku(s) and Sundrop 3s runtime test...

31 hours as I type, still cranking along on low level... all as bright as when I started, no difference in temp, etc. I am duly impressed...:bow: I keep expecting some dropoff, but compared to the control light, nothing doing. I am going to check on the half hour now, and post when something changes.

Thanks for doing this, Greg. So impressive....the lights and the dedication of the tester!! :thumbsup::thumbsup:

You've inspired me...when my 007 comes back I may test it alongside my LS27 and PD XPG to see how they stack up. Maybe even the T1A I was fortunate enough to get from you.

You are the man! Thanks for doing this!!

:thanks::thanks::thanks:

Wow! 31 hours, nice! Dont fall asleep, you'll wake up and they may all be dead.

Great job on this BTW!

Re: Haiku(s) and Sundrop 3s runtime test...

This is great I was hoping someone would run a test like this on the XP-G do you think the run time would be longer or shorter using 2 AA primary lithium's at 1.5 volts each this is what I run in my Haiku XP-G. Thanks its always good to know what your light will do and if your are not sure about my light then I will have to run a test and see. You have sparked my curiosity.

Re: Haiku(s) and Sundrop 3s runtime test...

With L91's, i would think it would be longer...

Well, ya gotta do it now!!! :tinfoil:

Re: Haiku(s) and Sundrop 3s runtime test...

Okay, here's the deal.

10:30 last night, the slightest dimming was noticed. If you did not have a control light, you wouldn't have noticed. 34 hours in.

12:30, just a bit more dimming.

3:35 AM, stilll going, still way too bright to use to wander the house, I needed my Titan on low to go to the kitchen. Ceiling bounce was enough to make Mrs. scout stir...

5:30AM, the XP-G had shut off, but the others were enough to light up my bedroom wall 8 feet away, as the sun was coming up. 41 hours in...

7:30 AM, the Sundrop and XR-E were flickering, and the test was ended. If I rested them, a'la the LS20 test, I could get another 5-10 minutes of light again... Kudos to Don, I loved these lights before, but with in-hand runtime under their belts, I am more impressed than ever. McGizmo's rule!!!

The two Haiku batteries went into my MC-2 at 9am, cooked, but the white nichia ran for 15 min. before the red kicked in, I'll let you know how long that runs on these two wasted batteries.

Re: Haiku(s) and Sundrop 3s runtime test...

5:40 pm, and the MC2 just started blinking with the red Nichia... That's another 8hrs and 40min. of steady light from two burnt batteries that had given 40+ hrs. of service in the Haikus on low. I think they are done now...

Impressive.

Curious s to why the XP-G didn't last as long as the XR-E?

Re: Haiku(s) and Sundrop 3s runtime test...

Fisk-king- I am assuming that there is some minor variance in the cells as well as the drivers, and think it was close enough to be within specs for all concerned. I am also sure if there was some stop-and-go as far as usage, the runtime would have been even longer. I do not have the patience to do, say, 1/2 hr. a day and document how many days and or hours that adds up to... Would be interesting, though. I hope Per-Sev does the 2xAA Lithium test, as I also have that body. I agree with PSM that it would be even longer.

Scout, thanks again for doing this, 40 hours is very nice!!! :twothumbs
