Juggernaut* LED Flashlight, retail $TBA (Homemade/modified)
Manufactured by (Unknown)
Last updated 12-02-10
It looks like a Mag.
It feels like a Mag.
It smells like a Mag.
But when you turn it on, this vivid white light pours out the end, instead of that sickly dim yellow "light" produced by an unmodified Mag-Lite.
The Juggernaut LED Flashlight uses six D cells to feed three white Luxeon I LEDs in the flashlight's "business-end". The LEDs are powered by a buck converter (reduces battery voltage), which is concealed inside the bezel somewhere behind the LEDs.
* I chose the name Juggernaut because in the TV series Digimon Tamers (which I really do like!), it was an extremely powerful weapon that was designed by people at Hypnos.

Use the Juggernaut LED Flashlight like you would use an unmodified Mag-Lite. Press the rubberised button on the barrel until it clicks and then release it to turn the flashlight on; press and release it the same way again to turn the flashlight off.
For momentary (signalling) use, press the button less firmly (before it clicks) and hold it that way for as long as you need the flashlight on; release the button to turn the flashlight off.
To change dead batteries in your Juggernaut, unscrew & remove the tailcap, and dump the dead batteries into the nearest garbage can (or the dead battery box, if your community has a battery reclamation program in place).
Load six new D cells in, button-end (+) positive first. Slide them in with the barrel of the light held mainly horizontally; if you hold the barrel vertically (so that the open end faces the ceiling) and drop the D cells in, something might become damaged -- and that "something" could cause the flashlight to cease functioning!!!
Finally, screw the tailcap firmly back on.
Done with that, fun ya!!!
If you disposed of the used D cells, be sure and empty that garbage can every now and again; you don't want baby funnel web spiders, dragonfly larvae, or mourningclock butterfly caterpillars (larvae).
Measures 593mA on alkaline D cells of unknown prior usage.
I do not normally administer "The Smack Test" on homemade and/or modified products, so you'll not be seeing results of that here. I know you like to see me try and break stuff, but "ain't" "gonna" happen today, folks!!!
When that dreadful suction test (a totally nondestructive test!!!) was performed at the rear portion of the barrel, no air leakage was detected. It holds a good partial vacuum. So the Juggernut should be splash- and weather-resistant at very minimum, and even submersible to shallow depths at minimum.
I cannot perform the even more dreadful "toliet test" here, as this flashlight is simply too large and heavy to properly fit into the cistern (toliet tank) to safely perform that particular test.
You can unscrew & remove the bezel and stand the Juggernaut on its tail to use it in candle mode. You will lose some water-resistance in this mode, so don't place it directly under the drip in a leaky tent when used this way. And because of its length (19.450"), it will not be exceptionally stable in this configuration -- but it can be done if necessary.
This is on D cells of unknown prior usage; I simply do not have the $$$ to purchase new ones at this time -- nor can I furnish an estimate of when I'll actually be able to purchase them.
This is also a fairly wide-angle source, and if I've told you once, I've told you 31,054,500 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!!!

Spectrographic analysis of the LEDs in this flashlight.
I can tell by the spike at ~615nm in the orange that they're Luxeon Star I LEDs.

TEST NOTES:
Test unit is clearly a modified Mag Lite; it is simply not known when I received it or even who furnished it.
If this was you, please pipe up so I can properly thank you for it.
This is the fictitious place known as Hypnos, tracking another bio-emergence (when a digimon crosses from the digital world into the real world).
