TerraLUX MiniStar2 Extreme Module, retail $26.99 (www.ledsupply.com...)

The MiniStar2 Extreme is a bright retrofit "bulb" designed to be used in a 2xAA Mini-Mag. It features a new Luxeon V K2 U Bin LED.

Regarding the two photographs above: the first one is of the module itself, and the second is of the finished flashlight.


This retrofit requires you to have a 2xAA cell Mini-Mag.
To install this retrofit, just follow the easy instructions directly below:
  1. Unscrew the head, and set it aside.
  2. Remove the incandescent bulb while it's burning. Throw the bulb in a drawer or somewhere else you can find it in case you ever want to go back to a regular bulb.
  3. Unscrew the two halves of the head section, remove the old reflector, and install the one supplied with the kit.
  4. Screw the head section back together.
  5. Insert the MiniStar2 in the two closely-spaced holes where the bulb went; do not twist. If it does not light, remove the module, rotate it 180 (spin it 1/2 a turn), and reinsert it. The module should light up at this point. That's kosher, it's supposed to do that.
  6. Screw the head back onto the barrel.
  7. Do not aim at face. Place on a hard surface. Light fuse and get away.
The beam is adjustable from spot to flood, just like an unmodified Mini-Mag, by turning the bezel (head) clockwise or conterclockwise.

To change dead batteries, unscrew & remove the tailcap, dump the two dead batteries in the nearest garbage can (or the dead battery box, if your community has a battery reclamation program), load the new AA cells in button (+) end first, then screw the tailcap firmly back on. See, that was easy, wasn't it?

Current measures 582mA on my DMM's 4A scale, when used with the two Duracell AA cells that came with the Mini-Mag.

As a flashlight, the unit is sturdy, and is of a proven physical design. Mag Instruments (of which TerraLUX has *no* affiliation!) has been making flashlights for years, and they have a long track record for durability. This LED module appears that it should live up to those standards, and allow you to get many more useful years out of your tired old (but still fully serviceable) Mini-Mag.

Please note: The K2 can draw as much as 6W when run at 1.5A. The LED is running at approximately 2.5W as the Maglite's plastic reflector cannot handle, nor can the body dissipate, the heat that is generated when the LED is operating at full power.

The module uses "PowerPush" technology, which is a regulator circuit to help ensure the LED intensity remains stable as the batteries discharge.

The unit can be used as an "electronic candle" by unscrewing & removing the bezel (head) and then standing the light on its tail. The light will lose water-resistance in this mode, so please do not place it directly under the drip in a damaged ceiling, or you might be rather sorry.

Test unit of this and another TerraLUX product were sent by Z.T. of www.ledsupply.com on 01-29-07, and were received on the afternoon of 02-01-07.

Product was made in the United States. A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 00-00-00

Very good intensity
Uses a flashlight host that's very common & relatively inexpensive
Uses batteries that are common & relatively inexpensive

A bit underdriven - but this is for both the module and flashlight sakes
