I just got the word from home that my package arrived which contains a new Arc4 with the most recent version of software + my Arc4x that also contains the lastest version. Over the next few nights, I plan on peforming comparative runtime tests of each light, using the LM631. I'll use the same criteria for all 3-lights, plot them to scale, and post the results here. This is going to be very interesting I think.
Stay tuned.
Edit #1:
OK, let's set the stage. Here's the constants and particulars of the testing.
- LM631 light meter is being used. There is an inverted white-colored film canaster that rests on top of the light sensor. The sensor is set to foot-candles, on the setting just before the 10x setting.
- SureFire 123-cells registering 3.27 volts without a load are used.
- The lights are resting on the canaster and is not moved or touched throughout the testing.
- The light is set to Level-1.
- Measurements were taken at the 5-minute interval, at the top of each minute.
I will probably run each test for 2.5 hours. The intent is to measure the Arc4-X first, then the Arc4, then the LSH-P and finally a second Arc4.
Edit #2:
OK, here's the 1st runtime test of the Arc4-X light. I won't get to another test tonight. That will need to wait until tomorrow night.
Edit #3:
Alrighty then, here's the completed chart with the Arc4x, Arc4+ and LSH lights. I ran each test 2.5 hours as noted earlier. Each light had a brand new SF 123-cell that measured exactly 3.27 volts (no load). None of the lights were held, touched or moved while the test was occurring, so I can comment on heat, etc. As another point-of-reference, an ARC-AAA loaded with a fresh cell would yield "90" on this chart.
Edit #4:
A plot has been added to the graph to display the 2.5 hour test of the Arc4x which starts on Level-4.
Edit #5:
A plot has been added to the graph to display the 2.5 hour test of the Arc4+ which starts on Level-4.
Edit #6:
A plot has been added to the graph to display the 2.5 hour test of the Arc4x which starts on Level-3.
Edit #7:
A plot has been added to the graph to display the 2.5 hour test of the FireFly with a MM+ wide-open running an R2H 1-watt LED. The FireFly does not fair well at all when compared to these other lights/settings, however I included it for comparision purposes.
Edit #8:
A plot has been added to the graph to display the 2.5 hour test of the LSH-P.
Edit #9:
A plot has been added to the graph to display the 2.5 hour test of the LSH-F, which has been modified with a Lux-III, Fraen optics and power increase to 667 mA.
Edit #10:
A plot has been added to the graph to display the 2.5 hour test of the LSH-F, which has been modified with a Lux-III, Fraen optics and power increase to 833 mA.
Stay tuned.
