Note the difference in beam colors. And then the relative light meter readings on this particular day, all taken in lux units from one meter away: 167 Lambda Illuminator 219 BadBoy 230 Pill 826 LGI (Legend 3AA direct drive mod) Actually I started the test 1 hour and 45 minutes ago using another LGI that has been my test bed light that's seen some torture already. Here are my readings so far: Ambient temps - 81 degrees F. Starting Time - 1830 hours Time - 1850 hrs Time - 1940 Time - 2000 Time - 2015 Got to get ready for work. Since it appears the temps are going down (along with lux and battery reserves) I may just leave it on and come back for additional readings later. Will do one final temp/brightness reading before heading out the door. It appears that as the batteries run down and output is less, this lowers the temps. At least that is what I am hoping. Also the LS should become more efficient as batteries are drained, and shift the light into a sort of "dusk" (not moon) mode, where it still provides fairly usable bright light, gradually diminishing over a longer period time. At least that's what I experienced with Wayne's direct drive MagLite Blasters, and hopefully it holds true here. After the light reaches a point where no real useful light (arbitrarily defined by MR Bulk as no longer able to help navigate a dark house or read fine newsprint), I will shut it down, let it cool off completely, insert fresh batteries and do a final light meter reading. Hopefully it gets back up into the 700s as it did initially. On a side note this is the same light I ran the other day for about 15 minutes where the case temp got up to 118.5F before I shut it down, so this is not a virgin LS -- it's lived a little and felt some heat already. After 2 hours and 15 minutes: Time - 2045 After 5 hours and 30 minutes: Time - 2400 Light output was still very usable, brighter than the
RAM 3-Nichia batonlight mounted on the end of my work-issued ASP baton,
and about as bright as a half-dimmed (5 clicks down) Eternalight Ergo
III and with a brighter hotspot than the Ergo:
I then terminated the test because from my experience with other 3-cell DirectDrives, at this point the light will continue at this "dusk" level for several days. After waiting 15 minutes for the batteries to recover, I metered it
again and got a reading of 244 lux. It was back up to being brighter
than the other three test lights. Wow here is a review of the LGI at THE LED MUSEUM. THANKS CRAIG!! The only thing wrong with making and selling mods is that I don't get to experience the thrill and anticipation of waiting for the postal carrier to receive lights. Now I wait for the postal carrier to give lights -- this is what my workbench looks like lately: 
Sighhhhh... Heatsinks for the latest batch of LGIs. First they are cut from a sheet of 1/8-inch thick aluminum, then two microscopic holes are drilled for the 30-gauge wire leads, then a slot is relieved between the holes on the underside so no wires are crimped during installation, then progressively buffed with 150-, 320-, and finally 600-grit sandpaper till they sparkle almost like tiny mirrors. Absolutely essential for the massive rate of heat transfer required by these little flamethrowers... Just so those of you waiting on orders know you have a bonafide anal-retentive
fanatic building your LGI:
