MJLED - Plugin LED Mod
Introducing the MJLED - The most efficient LED available today.

ArcMania has modified these new hi-power, super efficient
large die 5mm LEDs to function as side emitters for use in flashlights with
reflectors. These are a direct plug in replacement for the bi-pin incandescent
lamps used in popular two cell flashlights. Simply remove the stock incandescent
bulb, replace it with an MJLED and either drill out the reflector opening to
0.25 inch, or swap the reflector with a pre-drilled one from the complete MJLED
Kit. That's all there is to perform this modification to a flashlight.
Sound too good to be true? Well it's not, and we haven't told you about the best
part yet; the performance.
How does a 35 hour+ run time sound?

Note the initial illumination level of 180 Lux at one meter is about what the
first Arc Luxeon flashlights produced. But unlike the power hungry Luxeon LEDs,
the MJLED needs much less power to produce the same level of light which results
in a very long battery life. Heck, it's still turning out about 120 Lux after 24
hours continuous use.
In addition to the very long battery life, the color tint
of these LEDs is much better and consistent than Luxeon LEDs. No more "Luxeon
Lotto" hoping you don't get a dirty green tint. All the MJLEDs produce a
very white light with a slight blue tint, closely resembling a Luxeon BIN Y0
color temperature. And the special ground and polished lens produces a smooth,
bright beam with consistent tint.
While this isn't a super bright mod that will get "oohs and ahs" from
your friends, this is one flashlight mod nobody should be without. The 180 Lux
light level produced is perfect for walking trails while preserving most of your
natural night vision. The reflected illumination from the trail won't rob you of
your natural night vision, yet it's bright enough to light a pathway to easily
see obstacles on and off the trail. There's also plenty of light for tasks such
as looking behind the stereo to locate a jack to plug a cable into and other
similar common tasks.
This mod does require the use of Energizer AA or AAA lithium cells for best
performance, but alkaline cells can also be used with lesser performance.
Examples of MJLED modifications:
Here's a MiniMag 2AA flashlight that's been modified with an MJLED.

The MJLED plugs in place of the stock light bulb.

Here's a respectable 'light saber' beam shot against the wall.

And at tightest focus from about six feet (2 meters).
Note: Regular incandescent room lighting was on when these photos were taken
Here's a MiniMag 2AAA flashlight that's been modified with an MJLED.

Yes, it's finally possible to mod the 2AAA MiniMag!

In a snap you transform it in to a bright LED flashlight with a very long run time.

While we didn't have any lithium AAA cells on hand to test with, the recently
released AAA lithium cells should provide a big boost in performance over the
alkaline cells used for these photos. (Lithium AAA run time test coming soon)
Features Summary:
35 Hour+ run time on 2 Energizer lithium AA cells
180 Lux typical at one meter
Easy, "anybody can do it" simple installation
When supplied with lithium AA cells, this makes one of the longest burning
emergency lights with a 10 year shelf storage life. Never be left in the dark
again.
"If I were going cave exploring, this would at the
very least be hanging from my belt as a back up light, if not being used as the
primary illumination"
