Battle in the woods is about battle between the best compact led throwers vs the best compact HIDs.
It's a practical battle for supremacy of illumination of the cold dark woods. It's about throw but not completed about throw, as the spot size matters
Large dies were chosen for high lumen & big spot size. Smaller dies such as XPG-2 or de-domed XML were not used. Although they might be easier to achieve throw than the bigger dies, the much smaller beam spot reduces illumination coverage & thus not as useful as a searchlight in the woods.
I find even XML with dome produce too small of a spot in a 3" SMO reflector, it lost to HID even though the throw was higher (See Battle in the woods I). Thus, the the round III, much efforts were put into high current SBT-90 builds...

The Foxes won both previous battles. However, there are some new elephants in town, it's time for another round of battle.
The battle ground:
My back yard, twin skinny trees target 250 feet , the single big tree to the right of them is at 200 ft.
Photo Conditions: all are Manual Exposure: ISO 200: F3.3: 1 second exposure
While doing the beam shots, I also did 100 feet (30.5 meter) lux measurements out door.
Outdoor lux measured @ 30.5 meters under slight rain, saturated humidity, most numbers 5-10% lower than indoor 10 meter lux.
Left to right:
ThruNite TN31, XML U2 3.5A———————-100 ft outdoor wet, 106 Klux—-Indoor 10 meter lux -115 klux
FM3X Elephant CBT-90, 9A————————-100 ft outdoor wet, 100 Kux—-Indoor 10 meter lux—105 klux
FM3V Silver Elephant, CBT90,15A————100 ft outdoor wet, 150 Klux—Indoor 10 meter lux—155 klux
Fire-Fox III, 40W HID ————————————-100 ft outdoor wet, 200 Klux—-Indoor 10 meter lux—221 klux
Mr. Mayham, SR95 UT Elephant 10A—100 ft outdoor wet, 210 Klux—-Indoor 10 meter lux—228 klux
Darth Vader, 3" Aspheric XMLU2 6.5A-100 ft outdoor wet, 265 Klux—-Indoor 10 meter lux—280 klux

Last photo shows the lux meter placed at 100 ft out, Extech EZ30 meter. This is an excellent meter, the peak hold function is super useful,
allows long distance lux measurement to be done by a single person, without the need for a helper.
