LSH-P vs. KL-1 Runtime

[this_is_nascar]

This was not as extensive as what I'd like it to be, so I have another similar test in progress. This was a runtime and output test of my new LSH-P and KL-1 on an E1. Both had new Toshiba 123-cells measuring 3.26 volts. The LM631 was used and all readings are in the FC x 10 setting with the lights resting on the light sensor.

Time LSH-P E1-KL1
21:00 OL OL
22:20 OL OL
22:25 1015 1545
22:30 823 1470
22:38 681 1365

I then went to bed and left both lights on. Woke up at 05:30. I did not take measurements, however the KL1 was flickering. No flickering from the LSH-P. To my eyes they appeared to be very similar in brightness, but it was difficult to tell with the flickering of the KL1.

An early conclusion, based on this one and only test, shows me that the KL1 is doing a better job of using the 123-cell thru at least the first 1hr 38 min. I wish I could have gone further with the measurements. I'm curious how the readings would have progressed over the next few hours.

I'm hoping to get better numbers with the test that's currently running. After this test, I'll focus on the comparisions between my LSH-P, LS1 and LS1-REV2.

Test #2 is underway, but I'm finding the results interesting enough to post this now. The same lights were used. The same meter and method of measurement was used. The difference is this time I'm using SureFire 123-cells and they measure 3.26 volts (same as the Toshiba).

Time LSH-P E1-KL1
18:50 OL OL
19:48 OL 1999
20:05 OL 1997
20:25 OL 1858
20:53 OL 638
20:55 1999 576
21:00 814 464

Updated Times:
21:45 186 195 and flickering

The test is still going. Very strange results. Once this test is completed, I need to do one more again with the SF cells. I do like these results better, since they display a better yield on the LSH-P. I'll post my opinions of my new LSH-P in a seperate thread.

Very strange indeed.

I would recommend testing the pair with manufactuer recommended batteries, i.e. SF battery in KL1/E1 and Duracell Ultra in LSH.

<font size="2" face="Verdana, Arial">I don't beleive ARC makes a recommendation for 123-cells to power the LSH-P, however I do know that SureFire does for their line of products. I've always had best success with the SF cells, however this was a test to compare lights, not batteries. Doing what you had recommnended would have sqewed the results of the testing in SureFire's favor.
