Nailbender Modules in SureFire & Solar Force Hosts: Run Time Graphs

I've bought seven Nailbender XM-L U2 modules and have created some run time graphs. Copper tape was wrapped around all modules to increase heat transfer from the module to the host.















^With Fan

^NO Fan

^Same graph as above but with time scale out to 90 minutes. NO Fan.

Thank you very much for these graphs, really helps me out!

Just purchased a Nailbender drop-in and was wondering how the runtime would look with a 3100 and 2600.

I always assumed it was around half an hour on high, but i never measured it. Reinforces my use of this with a two-stage.. CR123s last at least a week with daily (12 hr work day) use. High mode is used sparingly, when actually needed!

I have two Solarforce L2M hosts that I have not put a drop-in into.

I was looking at the Solarforce XM-L U2 multi level drop-in to use.

Some CPFers do not rely on or trust the Solarforce drop-ins as they are only just alright.

I was wondering what Nailbender could offer as a suggestion for a Pocket Rocket drop-in similar to what I looked at above.

I was also wondering how that small L2M body would shed the heat properly even when using the copper tape to make good thermal contact when a high lumen drop-in is installed.

The graphs are all done with a fan blowing on them.

What happens when the same lights are subjected to high ambient real world temps as up in a non ventilated area like up in a ceiling or under a floor for us trade guys (Sparkies, Plumbers and handymen) who use these lights nearly every day.

What real role would Solarforce L2Ms with High Lumen LEDs have in a real world situation with little cooling?

Any suggestions would be helpful for me to populate these two L2M hosts just sitting around my bench laying idle.




Cheers

I added two more graphs showing the run time with NO fan. The last 3 graphs are of the same module (Smooth, 2 level, 2.8A). There's very little difference between the graphs when plotted up to 62 minutes; the fan has little impact on the run time graph. The L2T Head gets quite warm at 144F (62C). The body is only slightly cooler at 139F (59C).

The data below is with NO fan. An IR temperature sensor was used.

Elapsed Time, Minutes_____Head Temp, F (C)______Body Temp, F (C)
8_____________________114 (46)______________n/a
15____________________132 (56)______________n/a
30____________________144 (62)______________139 (59)
45____________________136 (58)______________130 (54)
60____________________129 (54)______________122 (50)
75____________________118 (48)______________112 (44)
90____________________107 (42)______________103 (39)
